Research on 1-million-pound thrust plus engine begun at Rocketdyne, the feasibility of which was established in March 1955.
The feasibility of a million-pound-thrust liquid-fueled rocket engine established by the Rocketdyne Division of North American Aviation, Inc.
First U.S.-built complete liquid-rocket engine having a thrust in excess of 400,000 pounds was fired for the first time at Santa Susana, Calif.
Rocket test stand capable of testing engines to 1 million pounds thrust activated at Edwards AFB, which became operational in March 1957.
The U.S. Army Ballistic Missile Agency, Redstone Arsenal, Ala., began studies of a large clustered-engine booster to generate 1.5 million pounds of thrust, as one of a related group of space vehicles. During 1957-1958, approximately 50,000 man-hours were expended in this effort.
Von Braun produces 'Proposal for a National Integrated Missile and Space Vehicle Development Plan'. First mention of 1,500,000 lbf booster (Saturn I)
A greatly expanded NACA program of space flight research was proposed in a paper, "A Program for Expansion of NACA Research in Space Flight Technology," written principally by senior engineers of the Lewis Aeronautical Laboratory under the leadership of Abe Silverstein. The goal of the program would be "to provide basic research in support of the development of manned satellites and the travel of man to the moon and nearby planets." The cost of the program was estimated at $241 million per year above the current NACA budget.
The U.S. Air Force contracted with NAA, Rocketdyne Division, for preliminary design of a single-chamber, kerosene and liquid-oxygen rocket engine capable of 1 to 1.5 million pounds of thrust. During the last week in July, Rocketdyne was awarded the contract to develop this engine, designated the F-1.
ARPA gives Von Braun team contract to develop Saturn I (called 'cluster's last stand' due to design concept).
Rocketdyne Division of North American announced an Air Force contract for a 1-million-pound thrust engine.
The Advanced Research Projects Agency ARPA provided the Army Ordnance Missile Command (AOMC) with authority and initial funding to develop the Juno V (later named Saturn launch vehicle. ARPA Order 14 described the project: "Initiate a development program to provide a large space vehicle booster of approximately 1.5 million pounds of thrust based on a cluster of available rocket engines. The immediate goal of this program is to demonstrate a full-scale captive dynamic firing by the end of calendar year 1959." Within AOMC, the Juno V project was assigned to the Army Ballistic Missile Agency at Redstone Arsenal Huntsville, Ala.
Saturn design studies authorized to proceed at Redstone Arsenal for development of 1.5-million-pound-thrust cluster first stage.
A letter contract was signed by NASA with NAA's Rocketdyne Division for the development of the H-1 rocket engine, designed for use in a clustered-engine booster.
Pioneer I, intended as a lunar probe, was launched by a Thor-Able rocket from the Atlantic Missile Range, with the Air Force acting as executive agent to NASA. The 39-pound instrumented payload did not reach escape velocity.
The Stever Committee, which had been set up on January 12, submitted its report on the civilian space program to NASA. Among the recommendations:
NASA requested DX priority for 1.5-million-pound-thrust F-1 engine project and Project Mercury.
A contract was signed by the University of Manchester, Manchester, England, and the Air Force (AF 61(052)-168) for $21,509. Z. Kopal, principal investigator, was to provide topographical information on the lunar surface for production of accurate lunar maps.
The Space Task Group (STG) was officially organized at Langley Field, Va., to implement the manned satellite project (later Project Mercury), NASA Administrator T. Keith Glennan had approved the formation of the Group, which had been working together for some months, on October 7. Its members were designated on November 3 by Robert R. Gilruth, Project Manager, and authorization was given by Floyd L. Thompson, Acting Director of Langley Research Center. STG would report directly to NASA Headquarters.
Secretary of the Army Wilber M. Brucker and NASA Administrator T. Keith Glennan signed cooperative agreements concerning NASA, Jet Propulsion Laboratory, Army Ordnance Missile Command AOMC, and Department of the Army relationships. The agreement covering NASA utilization of the von Braun team made "the AOMC and its subordinate organizations immediately, directly, and continuously responsive to NASA requirements."
Von Braun briefs NASA on plans for booster development at Huntsville with objective of manned lunar landing. Initally proposed using 15 Juno V (Saturn I) boosters to assemble 200,000 kg payload in earth orbit for direct landing on moon.
NASA awarded contract to Rocketdyne of North American to build single-chamber 1.5-million-pound-thrust rocket engine.
Representatives of Advanced Research Projects Agency, the military services, and NASA met to consider the development of future launch vehicle systems. Agreement was reached on the principle of developing a small number of versatile launch vehicle systems of different thrust capabilities, the reliability of which could be expected to be improved through use by both the military services and NASA.
The H-1 engine successfully completed its first full-power firing at NAA's Rocketdyne facility in Canoga Park, Calif.
Rocketdyne demonstrated 1-million-pound-thrust liquid-propellant rocket combustion chamber at full power.
In a staff report of the House Select Committee on Astronautics and Space Exploration, Wernher von Braun of the Army Ballistic Missile Agency predicted manned circumlunar flight within the next eight to ten years and a manned lunar landing and return mission a few years thereafter. Administrator T. Keith Glennan, Deputy Administrator Hugh L. Dryden, Abe Silverstein, John P. Hagen, and Homer E. Newell, all of NASA, also foresaw manned circumlunar flight within the decade as well as instrumented probes soft-landed on the moon. Roy K. Knutson, Chairman of the Corporate Space Committee, NAA, projected a manned lunar landing expedition for the early 1970's with extensive unmanned instrumented soft lunar landings during the last half of the 1960's.
The Army Ordnance Missile Command (AOMC), the Air Force, and missile contractors presented to the ARPA-NASA Large Booster Review Committee their views on the quickest and surest way for the United States to attain large booster capability. The Committee decided that the Juno V approach advocated by AOMC was best and NASA started plans to utilize the Juno V booster.
NASA signed a definitive contract with Rocketdyne Division, NAA, for $102 million covering the design and development of a single-chamber, liquid-propellant rocket engine in the 1- to l.5-million-pound-thrust class (the F-1, to be used in the Nova superbooster concept). NASA had announced the selection of Rocketdyne on December 12.
After consultation and discussion with DOD, NASA formulated a national space vehicle program. The central idea of the program was that a single launch vehicle should be developed for use in each series of future space missions. The launch vehicle would thus achieve a high degree of reliability, while the guidance and payload could be varied according to purpose of the mission. Four general-purpose launch vehicles were described: Vega, Centaur, Saturn, and Nova. The Nova booster stage would be powered by a cluster of four F-1 engines, the second stage by a single F-1, and the third stage would be the size of an intercontinental ballistic missile but would use liquid hydrogen as a fuel. This launch vehicle would be the first in a series that could transport a man to the lunar surface and return him safely to earth in a direct ascent mission. Four additional stages would be required in such a mission.
The Army proposed that the name of the large clustered-engine booster be changed from Juno V to Saturn, since Saturn was the next planet after Jupiter. Roy W. Johnson, Director of the Advanced Research Projects Agency, approved the name on February 3.
Maj. Gen. John B. Medaris of the Army Ordnance Missile Command (AOMC) and Roy W. Johnson of the Advanced Research Projects Agency (ARPA) discussed the urgency of early agreement between ARPA and NASA on the configuration of the Saturn upper stages. Several discussions between ARPA and NASA had been held on this subject. Johnson expected to reach agreement with NASA the following week. He agreed that AOMC would participate in the overall upper stage planning to ensure compatibility of the booster and upper stages.
A Working Group on Lunar Exploration was established by NASA at a meeting at Jet Propulsion Laboratory (JPL). Members of NASA, JPL, Army Ballistic Missile Agency, California Institute of Technology, and the University of California participated in the meeting. The Working Group was assigned the responsibility of preparing a lunar exploration program, which was outlined: circumlunar vehicles, unmanned and manned; hard lunar impact; close lunar satellites; soft lunar landings (instrumented). Preliminary studies showed that the Saturn booster with an intercontinental ballistic missile as a second stage and a Centaur as a third stage, would be capable of launching manned lunar circumnavigation spacecraft and instrumented packages of about one ton to a soft landing on the moon.
NASA issues plan for development in next decade of Vega (later cancelled as too similar to Agena), Centaur, Saturn, and Nova launch vehicles. Juno V renamed Saturn I.
Roy W. Johnson, Director of the Advanced Research Projects Agency (ARPA), testified before the House Committee on Science and Astronautics that DOD and ARPA had no lunar landing program. Herbert F. York, DOD Director of Defense Research and Engineering, testified that exploration of the moon was a NASA responsibility.
In testimony before the Senate Committee on Aeronautical and Space Sciences, Deputy Administrator Hugh L. Dryden and DeMarquis D. Wyatt described the long-range objectives of the NASA space program: an orbiting space station with several men, operating for several days; a permanent manned orbiting laboratory; unmanned hard-landing and soft-landing lunar probes; manned circumlunar flight; manned lunar landing and return; and, ultimately, interplanetary flight.
H. Kurt Strass and Leo T. Chauvin of STG proposed a heatshield test of a fullscale Mercury spacecraft at lunar reentry speeds. This test, in which the capsule would penetrate the earth's radiation belt, was called Project Boomerang. An advanced version of the Titan missile was to be the launch vehicle. The project was postponed and ultimately dropped because of cost.
The thrust chamber of the F-1 engine was successfully static-fired at the Santa Susana Air Force-Rocketdyne Propulsion Laboratory in California. More than one million pounds of thrust were produced, the greatest amount attained to that time in the United States.
The Army Ordnance Missile Command (AOMC) submitted the "Saturn System Study" which had been requested by the Advanced Research Projects Agency ARPA on December 18, 1958. From the 1375 possible configurations screened, and the 14 most promising given detailed study, the Atlas and Titan families were selected as the most attractive for upper staging. Either the 120-inch or the 160inch diameter was acceptable. The study included the statement: "An immediate decision by ARPA as to choice of upper stages on the first generation vehicle is mandatory if flight hardware is to be available to meet the proposed Saturn schedule."
John W. Crowley, Jr., NASA Director of Aeronautical and Space Research, notified the Ames, Lewis, and Langley Research Centers, the High Speed Flight Station (later Flight Research Center), the Jet Propulsion Laboratory, and the Office of Space Flight Development that a Research Steering Committee on Manned Space Flight would be formed. Harry J. Goett of Ames was to be Chairman of the Committee, which would assist NASA Headquarters in carrying out its responsibilities in long-range planning and basic research on manned space flight.
The advanced manned space program to follow Project Mercury was discussed at a NASA Staff Conference held in Williamsburg, Va. Three reasons for such a program were suggested:
NASA Administrator T. Keith Glennan requested $3 million for research into rendezvous techniques as part of the NASA budget for Fiscal Year 1960. In subsequent hearings, DeMarquis D. Wyatt, Assistant to the NASA Director of Space Flight Development, explained that these funds would be used to resolve certain key problems in making space rendezvous practical. Among these were the establishment of referencing methods for fixing the relative positions of two vehicles in space; the development of accurate, lightweight target-acquisition equipment to enable the supply craft to locate the space station; the development of very accurate guidance and control systems to permit precisely determined flight paths; and the development of sources of controlled power.
Testifying before the House Committee on Science and Astronautics, Francis B. Smith, Chief of Tracking Programs for NASA, described the network of stations necessary for tracking a deep-space probe on a 24-hour basis. The stations should be located about 120 degrees apart in longitude. In addition to the Goldstone, Calif., site, two other locations had been selected: South Africa and Woomera, Australia.
Members of the new Research Steering Committee on Manned Space Flight were nominated by the Ames, Lewis, and Langley Research Centers, the High Speed Flight Station (HSFS) (later Flight Research Center), the Jet Propulsion Laboratory (JPL), the Office of Space Flight Development OSFD), and the Office of Aeronautical and Space Research (OASR). They were: Alfred J. Eggers, Jr. (Ames); Bruce T. Lundin (Lewis); Laurence K. Loftin, Jr. (Langley); De E. Beeler (HSFS); Harris M. Schurmeier (JPL); Maxime A. Faget (STG) ; George M. Low of NASA Headquarters OSFD) ; and Milton B. Ames, Jr. (part-time) (OASR).
In response to a request by the DOD-NASA) Saturn Ad Hoc Committee, the Army Ordnance Missile Command (AOMC) sent a supplement to the "Saturn System Study" to the Advanced Research Projects Agency ARPA describing the use of Titan for Saturn upper stages.
The Army Ordnance Missile Command submitted to NASA a report entitled "Preliminary Study of an Unmanned Lunar Soft Landing Vehicle," recommending the use of the Saturn booster.
The first Rocketdyne H-1 engine for the Saturn arrived at the Army Ballistic Missile Agency (ABMA ). The H-1 engine was installed in the ABMA test stand on May 7, first test-fired on May 21, and fired for 80 seconds on May 29. The first long-duration firing - 151.03 seconds - was on June 2.
NASA created a committee to study problems of long-range lunar exploration to be headed by Dr. Robert Jastrow.
Milton W. Rosen of NASA Headquarters proposed a plan for obtaining high-resolution photographs of the moon. A three-stage Vega would place the payload within a 500-mile diameter circle on the lunar surface. A stabilized retrorocket fired at 500 miles above the moon would slow the instrument package sufficiently to permit 20 photographs to be transmitted at a rate of one picture per minute.
The first meeting of the Research Steering Committee on Manned Space Flight was held at NASA Headquarters. Members of the Committee attending were: Harry J. Goett, Chairman; Milton B. Ames, Jr. (part-time); De E. Beeler; Alfred J. Eggers, Jr.; Maxime A. Faget; Laurence K. Loftin, Jr.; George M. Low; Bruce T. Lundin; and Harris M. Schurmeier. Observers were John H. Disher, Robert M. Crane, Warren J. North, Milton W. Rosen (part-time), and H. Kurt Strass.
The purpose of the Committee was to take a long-term look at man-in-space problems, leading eventually to recommendations on future missions and on broad aspects of Center research programs to ensure that the Centers were providing proper information. Committee investigations would range beyond Mercury and Dyna-Soar but would not be overly concerned with specific vehicular configurations. The Committee would report directly to the Office of Aeronautical and Space Research.

Tentative manned space flight priorities were established by the Research Steering Committee: Project Mercury, ballistic probes, environmental satellite, maneuverable manned satellite, manned space flight laboratory, lunar reconnaissance satellite, lunar landing, Mars Venus reconnaissance, and Mars-Venus landing. The Committee agreed that each NASA Center should study a manned lunar landing and return mission, the study to include the type of propulsion, vehicle configuration, structure, anti guidance requirements. Such a mission was an end objective; it did not have to be supported on the basis that it would lead to a more useful end. It would also focus attention at the Centers on the problems of true space flight.
ABMA static fired a single H-1 Saturn engine at Redstone Arsenal, Ala.
Director Robert R. Gilruth met with members of his STG staff (Paul E. Purser, Charles J. Donlan, James A. Chamberlin, Raymond L. Zavasky, W. Kemble Johnson, Charles W. Mathews, Maxime A. Faget, and Charles H. Zimmeman) and George M. Low from NASA Headquarters to discuss the possibility of an advanced manned spacecraft.
A report entitled "Recoverable Interplanetary Space Probe" was issued at the direction of C. Stark Draper, Director of the Instrumentation Laboratory, MIT. Several organizations had participated in this study, which began in 1957.
Construction of the first Saturn launch area, Complex 34, began at Cape Canaveral, FIa.
At an STG staff meeting, Director Robert R. Gilruth suggested that study should be made of a post-Mercury program in which maneuverable Mercury spacecraft would make land landings in limited areas.
NASA authorized $150,000 for Army Ordnance Missile Command studies of a lunar exploration program based on Saturn-boosted systems. To be included were circumlunar vehicles, unmanned and manned; close lunar orbiters; hard lunar impacts; and soft lunar landings with stationary or roving payloads.
Members of STG - including H. Kurt Strass, Robert L. O'Neal, Lawrence W. Enderson, Jr., and David C. Grana - and Thomas E. Dolan of Chance Vought Corporation worked on advanced design concepts of earth orbital and lunar missions. The goal was a manned lunar landing within ten years, rather than an advanced Mercury program.
Members of the Research Steering Committee determined the study and research areas which would require emphasis for manned flight to and from the moon and for intermediate flight steps:
At the second meeting of the Research Steering Committee on Manned Space Flight, held at the Ames Research Center, members presented reports on intermediate steps toward a manned lunar landing and return.
Bruce T. Lundin of the Lewis Research Center reported to members on propulsion requirements for various modes of manned lunar landing missions, assuming a 10,000-pound spacecraft to be returned to earth. Lewis mission studies had shown that a launch into lunar orbit would require less energy than a direct approach and would be more desirable for guidance, landing reliability, etc. From a 500,000 foot orbit around the moon, the spacecraft would descend in free fall, applying a constant-thrust decelerating impulse at the last moment before landing. Research would be needed to develop the variable-thrust rocket engine to be used in the descent. With the use of liquid hydrogen, the launch weight of the lunar rocket and spacecraft would be 10 to 11 million pounds.
A report on a projected manned space station was made to the Research Steering Committee by Laurence K. Loftin, Jr., of the Langley Research Center. In discussion, Chairman Harry J. Goett expressed his opinion that consideration of a space laboratory ought to be an integral and coordinated part of the planning for the lunar landing mission. George M. Low of NASA Headquarters warned that care should be exercised to assure that each step taken toward the goal of a lunar landing was significant, since the number of steps that could be funded was extremely limited.
Alfred J. Eggers, Jr., of the Ames Research Center told the members of the Research Steering Committee of studies on radiation belts, graze and orbit maneuvers on reentry, heat transfer, structural concepts and requirements, lift over drag considerations, and guidance systems which affected various aspects of the manned lunar mission. Eggers said that Ames had concentrated on a landing maneuver involving a reentry approach over one of the poles to lessen radiation exposure, a graze through the outer edge of the atmosphere to begin an earth orbit, and finally reentry and landing.
The Advanced Research Projects Agency (ARPA) directed the Army Ordnance Missile Command to proceed with the static firing of the first Saturn vehicle, the test booster SA-T, in early calendar year 1960 in accordance with the $70 million program and not to accelerate for a January 1960 firing. ARPA asked to be informed of the scheduled firing date.
Meetings of the STG New Projects Panel to discuss an advanced manned space flight program.
The STG New Projects Panel (proposed by H. Kurt Strass in June) held its first meeting to discuss NASA's future manned space program. Present were Strass, Chairman, Alan B. Kehlet, William S. Augerson, Jack Funk, and other STG members. Strass summarized the philosophy behind NASA's proposed objective of a manned lunar landing : maximum utilization of existing technology in a series of carefully chosen projects, each of which would provide a firm basis for the next step and be a significant advance in its own right.
At its second meeting, STG's New Projects Panel decided that the first major project to be investigated would be the second-generation reentry capsule. The Panel was presented a chart outlining the proposed sequence of events for manned lunar mission system analysis. The target date for a manned lunar landing was 1970.
A House Committee Staff Report stated that lunar flights would originate from space platforms in earth orbit according to current planning. The final decision on the method to be used, "which must be made soon," would take into consideration the difficulty of space rendezvous between a space platform and space vehicles as compared with the difficulty of developing single vehicles large enough to proceed directly from the earth to the moon.
McDonnell Aircraft Corporation reported to NASA the results of several company-funded studies of follow-on experiments using Mercury spacecraft with heatshields modified to withstand lunar reentry conditions. In one experiment, a Centaur booster would accelerate a Mercury spacecraft plus a third stage into an eccentric earth orbit with an apogee of about 1,200 miles, so that the capsule would reenter at an angle similar to that required for reentry from lunar orbit. The third stage would then fire, boosting the spacecraft to a speed of 36,000 feet per second as it reentered the atmosphere.
A study of the guidance and control design for a variety of space missions began at the MIT Instrumentation Laboratory under a NASA contract.
The ARPA-NASA Booster Evaluation Committee appointed by Herbert F. York, DOD Director of Defense Research and Engineering, April 15, 1959, convened to review plans for advanced launch vehicles. A comparison of the Saturn (C-1) and the Titan-C boosters showed that the Saturn, with its substantially greater payload capacity, would be ready at least one year sooner than the Titan-C. In addition, the cost estimates on the Titan-C proved to be unrealistic. On the basis of the Advanced Research Projects Agency presentation, York agreed to continue the Saturn program but, following the meeting, began negotiations with NASA Administrator T. Keith Glennan to transfer the Army Ballistic Missile Agency (and, therefore, Saturn ) to NASA.
At the third meeting of STG's New Projects Panel, Alan B. Kehlet presented suggestions for the multimanned reentry capsule. A lenticular-shaped vehicle was proposed, to ferry three occupants safely to earth from a lunar mission at a velocity of about 36,000 feet per second.
After a meeting with officials concerned with the missile and space program, President Dwight D. Eisenhower announced that he intended to transfer to NASA control the Army Ballistic Missile Agency's Development Operations Division personnel and facilities. The transfer, subject to congressional approval, would include the Saturn development program.
President Eisenhower announced his intention of transferring the Saturn project to NASA, which became effective on March 15, 1960.
At an STG meeting, it was decided to begin planning of advanced spacecraft systems. Three primary assignments were made:
In a memorandum to the members of the Research Steering Committee on Manned Space Flight, Chairman Harry J. Goett discussed the increased importance of the weight of the "end vehicle" in the lunar landing mission. This was to be an item on the agenda of the third meeting of the Committee, to be held in early December. Abe Silverstein, Director of the NASA Office of Space Flight Development, had recently mentioned to Goett that a decision would be made within the next few weeks on the configuration of successive generations of Saturn, primarily the upper stages, Silverstein and Goett had discussed the Committee's views on a lunar spacecraft. Goett expressed the hope in the memorandum that members of the Committee would have some specific ideas at their forthcoming meeting about the probable weight of the spacecraft.
In addition, Goett informed the Committee that the Vega had been eliminated as a possible booster for use in one of the intermediate steps leading to the lunar mission. The primary possibility for the earth satellite mission was now the first-generation Saturn and for the lunar flight the second-generation Saturn.
While awaiting the formal transfer of the Saturn program, NASA formed a study group to recommend upper-stage configurations. Membership was to include the DOD Director of Defense Research and Engineering and personnel from NASA, Advanced Research Projects Agency, Army Ballistic Missile Agency, and the Air Force. This group was later known both as the Saturn Vehicle Team and the Silverstein Committee (for Abe Silverstein, Chairman).
The initial plan for transferring the Army Ballistic Missile Agency and Saturn to NASA was drafted. It was submitted to President Dwight D. Eisenhower on December 1 1 and was signed by Secretary of the Army Wilber M. Brucker and Secretary of the Air Force James H. Douglas on December 16 and by NASA Administrator T. Keith Glennan on December 17.
The Advanced Research Projects Agency ARPA and NASA requested the Army Ordnance Missile Command AOMC to prepare an engineering and cost study for a new Saturn configuration with a second stage of four 20,000-pound-thrust liquid-hydrogen and liquid-oxygen engines (later called the S-IV stage) and a modified Centaur third stage using two of these engines later designated the S-V stage).
At the third meeting of the Research Steering Committee on Manned Space Flight held at Langley Research Center, H. Kurt Strass reported on STG's thinking on steps leading to manned lunar flight and on a particular capsule-laboratory spacecraft. The project steps beyond Mercury were: radiation experiments, minimum space and reentry vehicle (manned), temporary space laboratory (manned), lunar data acquisition (unmanned), lunar circumnavigation or lunar orbiter (unmanned), lunar base supply (unmanned), and manned lunar landing. STG felt that the lunar mission should have a three-man crew. A configuration was described in which a cylindrical laboratory was attached to the reentry capsule. This laboratory would provide working space for the astronauts until it was jettisoned before reentry. Preliminary estimates put the capsule weight at about 6,600 pounds and the capsule plus laboratory at about 10,000 pounds.
H. H. Koelle told members of the Research Steering Committee of mission possibilities being considered at the Army Ballistic Missile Agency. These included an engineering satellite, an orbital return capsule, a space crew training vehicle, a manned orbital laboratory, a manned circumlunar vehicle, and a manned lunar landing and return vehicle. He described the current Saturn configurations, including the "C" launch vehicle to be operational in 1967. The Saturn C (larger than the C-1) would be able to boost 85,000 pounds into earth orbit and 25,000 pounds into an escape trajectory.
Several possible configurations for a manned lunar landing by direct ascent being studied at the Lewis Research Center were described to the Research Steering Committee by Seymour C. Himmel. A six-stage launch vehicle would be required, the first three stages to boost the spacecraft to orbital speed, the fourth to attain escape speed, the fifth for lunar landing, and the sixth for lunar escape with a 10,000-pound return vehicle. One representative configuration had an overall height of 320 feet. H. H. Koelle of the Army Ballistic Missile Agency argued that orbital assembly or refueling in orbit (earth orbit rendezvous) was more flexible, more straightforward, and easier than the direct ascent approach. Bruce T. Lundin of the Lewis Research Center felt that refueling in orbit presented formidable problems since handling liquid hydrogen on the ground was still not satisfactory. Lewis was working on handling cryogenic fuels in space.
Committee formed to recommend post-Mercury space program. After four meetings, and studying earth-orbit assembly using Saturn II or direct ascent using Nova, tended to back development of Nova.
NASA team completed study design of upper stages of Saturn launch vehicle.
In a memorandum to Don R. Ostrander, Director of Office of Launch Vehicle Programs, and Abe Silverstein, Director of Office of Space Flight Programs, NASA Associate Administrator Richard E. Horner described the proposed Space Exploration Program Council, which would be concerned primarily with program development and implementation. The Council would be made up of the Directors of the Jet Propulsion Laboratory, the Goddard Space Flight Center, the Army Ballistic Missile Agency, the Office of Space Flight Programs, and the Office of Launch Vehicle Programs. Horner would be Chairman of the Council which would have its first meeting on January 28-29, 1960 (later changed to February 10-11, 1960).
NASA accepted the recommendations of the Saturn Vehicle Evaluation Committee Silverstein Committee on the Saturn C-1 configuration and on a long-range Saturn program. A research and development plan of ten vehicles was approved. The C-1 configuration would include the S-1 stage (eight H-1 engines clustered, producing 1.5 million pounds of thrust), the S-IV stage (four engines producing 80,000 pounds of thrust), and the S-V stage two engines producing 40,000 pounds of thrust.
President Dwight D. Eisenhower directed NASA Administrator T. Keith Glennan "to make a study, to be completed at the earliest date practicable, of the possible need for additional funds for the balance of FY 1960 and for FY 1961 to accelerate the super booster program for which your agency recently was given technical and management responsibility."
In testimony before the House Committee on Science and Astronautics, Richard E. Horner, Associate Administrator of NASA, presented NASA's ten-year plan for 1960-1970. The essential elements had been recommended by the Research Steering Committee on Manned Space Flight. NASA's Office of Program Planning and Evaluation, headed by Homer J. Stewart, formalized the ten-year plan.
On February 19, NASA officials again presented the ten-year timetable to the House Committee. A lunar soft landing with a mobile vehicle had been added for 1965. On March 28, NASA Administrator T. Keith Glennan described the plan to the Senate Committee on Aeronautical and Space Sciences. He estimated the cost of the program to be more than $1 billion in Fiscal Year 1962 and at least $1.5 billion annually over the next five years, for a total cost of $12 to $15 billion.
The Chance Vought Corporation completed a company-funded, independent, classified study on manned lunar landing and return (MALLAR), under the supervision of Thomas E. Dolan. Booster limitations indicated that earth orbit rendezvous would be necessary. A variety of lunar missions were described, including a two-man, 14-day lunar landing and return. This mission called for an entry vehicle of 6,600 pounds, a mission module of 9,000 pounds, and a lunar landing module of 27,000 pounds. It incorporated the idea of lunar orbit rendezvous though not specifically by name.
At a luncheon in Washington, Abe Silverstein, Director of the Office of Space Flight Programs, suggested the name "Apollo" for the manned space flight program that was to follow Mercury. Others at the luncheon were Don R. Ostrander from NASA Headquarters and Robert R. Gilruth, Maxime A. Faget, and Charles J. Donlan from STG.
The Army Ballistic Missile Agency submitted to NASA the study entitled "A Lunar Exploration Program Based Upon Saturn-Boosted Systems." In addition to the subjects specified in the preliminary report of October 1, 1959, it included manned lunar landings.
The first meeting of the NASA Space Exploration Council was held at NASA Headquarters. The objective of the Council was "to provide a mechanism for the timely and direct resolution of technical and managerial problems . . . common to all NASA Centers engaged in the space flight program."
Study issued by Huntsville of lunar landing alternatives using Saturn systems. Huntsville transferred from Army to NASA. Vought study on modular approach to lunar landing. Internally NASA decides on lunar landing as next objective after Mercury.
Eleven companies submitted contract proposals for the Saturn second stage (S-IV): Bell Aircraft Corporation; The Boeing Airplane Company; Chrysler Corporation; General Dynamics Corporation, Convair Astronautics Division; Douglas Aircraft Company, Inc.; Grumman Aircraft Engineering Corporation; Lockheed Aircraft Corporation; The Martin Company; McDonnell Aircraft Corporation; North American Aviation, Inc.; and United Aircraft Corporation.

NASA established the Office of Life Sciences Programs with Clark T. Randt as Director. The Office would assist in the fields of biotechnology and basic medical and behavioral sciences. Proposed biological investigations would include work on the effects of space and planetary environments on living organisms, on evidence of extraterrestrial life forms, and on contamination problems. In addition, the Office would arrange grants and contracts and plan a life sciences research center.
At a NASA staff conference at Monterey, Calif., officials discussed the advanced manned space flight program, the elements of which had been presented to Congress in January. The Goddard Space Flight Center was asked to define the basic assumptions to be used by all groups in the continuing study of the lunar mission. Some problems already raised were: the type of heatshield needed for reentry and tests required to qualify it, the kind of research and development firings, and conditions that would be encountered in cislunar flight.
STG formulated preliminary guidelines by which an "advanced manned spacecraft and system" would be developed. These guidelines were further refined and elaborated; they were formally presented to NASA Centers during April and May.
The Army Ballistic Missile Agency's Development Operations Division and the Saturn program were transferred to NASA after the expiration of the 60-day limit for congressional action on the President's proposal of January 14. (The President's decision had been made on October 21, 1959.) By Executive Order, the President named the facilities the "George C. Marshall Space Flight Center." Formal transfer took place on July 1.
Thomas E. Dolan of the Chance Vought Corporation prepared a company-funded design study of the lunar orbit rendezvous method for accomplishing the lunar landing mission.
Two of Saturn's first-stage engines passed initial static firing test of 7.83 seconds duration at Huntsville, Ala.
STG's Robert O. Piland, during briefings at NASA Centers, presented a detailed description of the guidelines for missions, propulsion, and flight time in the advanced manned spacecraft program:
Presentation by STG members of the guidelines for an advanced manned spacecraft program to NASA Centers.
Members of STG presented guidelines for an advanced manned spacecraft program to NASA Centers to enlist research assistance in formulating spacecraft and mission design.
To open these discussions, Director Robert R. Gilruth summarized the guidelines: manned lunar reconnaissance with a lunar mission module, corollary earth orbital missions with a lunar mission module and with a space laboratory, compatibility with the Saturn C-1 or C-2 boosters (weight not to exceed 15,000 pounds for a complete lunar spacecraft and 25,000 pounds for an earth orbiting spacecraft), 14-day flight time, safe recovery from aborts, ground and water landing and avoidance of local hazards, point (ten square-mile) landing, 72-hour postlanding survival period, auxiliary propulsion for maneuvering in space, a "shirtsleeve" environment, a three-man crew, radiation protection, primary command of mission on board, and expanded communications and tracking facilities. In addition, a tentative time schedule was included, projecting multiman earth orbit qualification flights beginning near the end of the first quarter of calendar year 1966.
In discussing the advanced manned spacecraft program at NASA Centers, Maxime A. Faget of STG detailed the guidelines for aborted missions and landing:
Stanley C. White of STG outlined at NASA Centers the guidelines for human factors in the advanced manned spacecraft program:
Command and communications guidelines for the advanced manned spacecraft program were listed by STG's Robert G. Chilton at NASA Centers:
John C. Houbolt of the Langley Research Center presented a paper at the National Aeronautical Meeting of the Society of Automotive Engineers in New York City in which the problems of rendezvous in space with the minimum expenditure of fuel were considered.
Four of the eight H-1 engines of the Saturn C-1 first-stage booster were successfully static-fired at Redstone Arsenal for seven seconds.
Briefings on the guidelines for the advanced manned spacecraft program were presented by STG representatives at NASA Headquarters.
STG members, visiting Moffett Field, Calif., briefed representatives of the Jet Propulsion Laboratory, Flight Research Center, and Ames Research Center on the advanced manned spacecraft program. Ames representatives then described work at their Center which would be applicable to the program: preliminary design studies of several aerodynamic configurations for reentry from a lunar trajectory, guidance and control requirements studies, potential reentry heating experiments at near-escape velocity, flight simulation, and pilot display and navigation studies. STG asked Ames to investigate heating and aerodynamics on possible lifting capsule configurations. In addition, Ames offered to tailor a payload applicable to the advanced program for a forthcoming Wallops Station launch.
In a memorandum to NASA Administrator T. Keith Glennan, Robert L. King, Executive Secretary of the Space Exploration Program Council (SEPC), reported on the status of certain actions taken up at the first meeting of the Council:
Members of STG visited the Flight Research Center to be briefed on current effort and planned activities there. Of special interest were possibilities of the Flight Research Center's conducting research on large parachutes in cooperation with Ames Research Center, analytical and simulator studies of pilot control of launch vehicles, and full-scale tests of landing capabilities of low lift over drag configurations.
NASA announced the selection of the Douglas Aircraft Company to build the second stage (S-IV) of the Saturn C-1 launch vehicle.
At Redstone Arsenal, all eight H-1 engines of the first stage of the Saturn C-1 launch vehicle were static-fired simultaneously for the first time and achieved 1.3 million pounds of thrust.
A study report was issued by the MIT Instrumentation Laboratory on guidance and control design for a variety of space missions. This report, approved by C. Stark Draper, Director of the Laboratory, showed that a vehicle, manned or unmanned, could have significant onboard navigation and guidance capability.
Members of STG presented the proposed advanced manned spacecraft program to Wernher von Braun and 25 of his staff at Marshall Space Flight Center. During the ensuing discussion, the merits of a completely automatic circumlunar mission were compared with those of a manually operated mission. Further discussions were scheduled.
STG members presented the proposed advanced manned spacecraft program to the Lewis Research Center staff. Work at the Center applicable to the program included: analysis and preliminary development of the onboard propulsion system, trajectory analysis, and development of small rockets for midcourse and attitude control propulsion.
Robcrt R. Gilruth, Paul E. Purser, James A. Chamberlin, Maxime A. Faget, and H. Kurt Strass of STG met with a group from the Grumman Aircraft Engineering Corporation to discuss advanced spacecraft programs. Grumman had been working on guidance requirements for circumlunar flights under the sponsorship of the Navy and presented Strass with a report of this work.
A discussion on the advanced manned spacecraft program was held at the Langley Research Center with members of STG and Langley Research Center, together with George M. Low and Ernest O. Pearson, Jr., of NASA Headquarters and Harry J. Goett of Goddard Space Flight Center. Floyd L. Thompson, Langley Director, said that Langley would be studying the radiation problem, making configuration tests (including a lifting Mercury) , and studying aerodynamics, heating, materials, and structures.
The consensus of the meeting was that the rendezvous technique would be essential in the foreseeable future and that experiments should be made to establish feasibility and develop the technique. There was as yet no funding for my rendezvous flight test program.
STG formed the Advanced Vehicle Team, reporting directly to Robert R. Gilruth, Director of the Mercury program. The Team would conduct research and make preliminary design studies for an advanced multiman spacecraft.
Eight H-1 engines of the first stage of the Saturn C-1 launch vehicle were static-fired for 35.16 seconds, producing 1.3 million pounds of thrust. This first public demonstration of the H-1 took place at Marshall Space Flight Center.
Assembly of the first Saturn flight booster, SA-1, began at Marshall Space Flight Center.
NASA selected Rocketdyne Division of NAA to develop the J-2, a 200,000-pound-thrust rocket engine, burning liquid hydrogen and liquid oxygen. (A decision was later made to use the J-2 in the upper stages of the Saturn C-5.)
Complete eight-engine static firing of Saturn successfully conducted for 110 seconds at MSFC, the longest firing to date.
The Saturn C-1 first stage successfully completed its first series of static tests at the Marshall Space Flight Center with a 122-second firing of all eight H-1 engines.
H. Kurt Strass of STG and John H. Disher of NASA Headquarters proposed that boilerplate Apollo spacecraft be used in some of the forthcoming Saturn C-1 hunches. (Boilerplates are research and development vehicles which simulate production spacecraft in size, shape, structure, mass, and center of gravity.) These flight tests would provide needed experience with Apollo systems and utilize the Saturn boosters effectively. Four or five such tests were projected. On October 5, agreement was reached between members of Marshall Space Flight Center and STG on tentative Saturn vehicle assignments and flight plans.
Robert O. Piland, Head of the STG Advanced Vehicle Team, and Stanley C. White of STG attended a meeting in Washington, D. C., sponsored by the NASA Office of Life Sciences Programs, to discuss radiation and its effect on manned space flight. Their research showed that it would be impracticable to shield against the inner Van Allen belt radiation but possible to shield against the outer belt with a moderate amount of protection.
The House Committee on Science and Astronautics declared: "A high priority program should be undertaken to place a manned expedition on the moon in this decade. A firm plan with this goal in view should be drawn up and submitted to the Congress by NASA. Such a plan, however, should be completely integrated with other goals, to minimize total costs. The modular concept deserves close study. Particular attention should be paid immediately to long lead-time phases of such a program." The Committee also recommended that development of the F-1 engine be expedited in expectation of the Nova launch vehicle, that there be more research on nuclear engines and less conventional engines before freezing the Nova concept, and that the Orion project be turned over to NASA. It was the view of the Committee that "NASA's 10-year program is a good program, as far as it goes, but it does not go far enough. Furthermore the space program is not being pushed with sufficient energy."
The third meeting of the Space Exploration Program Council was held at NASA Headquarters. The question of a speedup of Saturn C-2 production and the possibility of using nuclear upper stages with the Saturn booster were discussed. The Office of Launch Vehicle Programs would plan a study on the merits of using nuclear propulsion for some of NASA's more sophisticated missions. If the study substantiated such a need, the amount of in-house basic research could then be determined.
NASA Director of Space Flight Programs Abe Silverstein notified Harry J. Goett, Director of the Goddard Space Flight Center, that NASA Administrator T. Keith Glennan had approved the name "Apollo" for the advanced manned space flight program. The program would be so designated at the forthcoming NASA-Industry Program Plans Conference.
The first NASA-Industry Program Plans Conference was held in Washington, D.C. The purpose was to give industrial management an overall picture of the NASA program and to establish a basis for subsequent conferences to be held at various NASA Centers. The current status of NASA programs was outlined, including long-range planning, launch vehicles, structures and materials research, manned space flight, and life sciences.
NASA Deputy Administrator Hugh L. Dryden announced that the advanced manned space flight program had been named "Apollo." George M. Low, NASA Chief of Manned Space Flight, stated that circumlunar flight and earth orbit missions would be carried out before 1970. This program would lead eventually to a manned lunar landing and a permanent manned space station.
Name 'Apollo' selected by Silverstein. Conference with aerospace industry outlined NASA's plans for circumlunar and lunar flight.

In a memorandum to Abe Silverstein, Director of NASA's Office of Space Flight Programs, Harry J. Goett, Director of Goddard Space Flight Center, outlined the tentative program of the Goddard industry conference to be held on August 30. At this conference, more details of proposed study contracts for an advanced manned spacecraft would be presented. The requirements would follow the guidelines set down by STG and presented to NASA Headquarters during April and May. Three six-month study contracts at $250,000 each would be awarded.
Secretary of the Interior Fred A. Seaton and Secretary of the Army Wilber M. Brucker announced that the U.S. Geological Survey had completed the first known photogeological survey of the surface of the moon.
Army announced completion of a project for mapping lunar landing sites.
The Goddard Space Flight Center GSFC conducted its industry conference in Washington, D.C., presenting details of GSFC projects, current and future. The objectives of the proposed six-month feasibility contracts for an advanced manned spacecraft were announced.
In an organizational change within STG, Maxime A. Faget was appointed Chief of the Flight Systems Division and Robert O. Piland was named Assistant Chief for Advanced Projects. The Apollo Project Office was formed with Piland as Head of the Office; members included John B. Lee, J. Thomas Markley, William W. Petynia,and H. Kurt Strass.
NASA Administrator T. Keith Glennan directed that an accelerated joint planning effort be made by persons at NASA Headquarters who were most familiar with the Saturn, Apollo, manned orbital laboratory, and unmanned lunar and planetary programs. They were to determine whether the Saturn and Saturn-use programs were effectively integrated and whether sufficient design study and program development work had been done to support decisions on projected Saturn configurations.
A NASA contract for approximately $44 million was signed by Rocketdyne Division of NAA for the development of the J-2 engine.
A formal agreement was signed by the United States and South Africa providing for the construction of a new deep-space tracking facility at Krugersdorp, near Johannesburg. It would be one of three stations equipped to maintain constant contact with lunar and planetary spacecraft.
Bidder's conference for circumlunar Apollo. Specification: Saturn C-2 compatability (6,800 kg mass for circumlunar mission); 14 day flight time; three-man crew in shirt-sleeve environment.
An STG briefing was held at Langley Field, Va., for prospective bidders on three six-month feasibility studies of an advanced manned spacecraft as part of the Apollo program. A formal Request for Proposal was issued at the conference.
Charles J. Donlan of STG, Chairman of the Evaluation Board which would consider contractors' proposals on feasibility studies for an advanced manned spacecraft, invited the Directors of Ames Research Center, Jet Propulsion Laboratory, Flight Research Center, Lewis Research Center, Langley Research Center, and Marshall Space Flight Center to name representatives to the Evaluation Board. The first meeting was to be held on October 10 at Langley Field, Va.
The fourth meeting of the Space Exploration Program Council was held at NASA Headquarters. The results of a study on Saturn development and utilization was presented by the Ad Hoc Saturn Study Committee. Objectives of the study were to determine (1) if and when the Saturn C-2 launch vehicle should be developed and (2) if mission and spacecraft planning was consistent with the Saturn vehicle development schedule. No change in the NASA Fiscal Year 1962 budget was contemplated. The Committee recommended that the Saturn C-2 development should proceed on schedule (S-II stage contract in Fiscal Year 1962, first flight in 1965). The C-2 would be essential, the study reported, for Apollo manned circumlunar missions, lunar unmanned exploration, Mars and Venus orbiters and capsule landers, probes to other planets and out-of- ecliptic, and for orbital starting of nuclear upper stages.
Members were appointed to the Technical Assessment Panels and the Evaluation Board to consider industry proposals for Apollo spacecraft feasibility studies. Members of the Evaluation Board were: Charles J. Donlan (STG), Chairman; Maxime A. Faget (STG) ; Robert O. Piland (STG), Secretary; John H. Disher (NASA Headquarters Office of Space Flight Programs); Alvin Seiff (Ames); John V. Becker (Langley); H. H. Koelle (Marshall); Harry J. Goett (Goddard), ex officio; and Robert R. Gilruth (STG), ex officio.
Members of STG visited the Marshall Space Flight Center to discuss possible Saturn and Apollo guidance integration and potential utilization of Apollo onboard propulsion to provide a reserve capability. Agreement was reached on tentative Saturn vehicle assignments on abort study and lunar entry simulation; on the use of the Saturn guidance system; and on future preparations of tentative flight plans for Saturns SA-6, 8, 9, and 10.
Contractors' proposals on feasibility studies for an advanced manned spacecraft were received by STG. Sixty-four companies expressed interest in the Apollo program, and of these 14 actually submitted proposals: The Boeing Airplane Company; Chance Vought Corporation; Convair/Astronautics Division of General Dynamics Corporation; Cornell Aeronautical Laboratory, Inc.; Douglas Aircraft Company; General Electric Company; Goodyear Aircraft Corporation; Grumman Aircraft Engineering Corporation; Guardite Division of American Marietta Company; Lockheed Aircraft Corporation; The Martin Company; North American Aviation, Inc.; and Republic Aviation Corporation. These 14 companies, later reduced to 12 when Cornell and Guardite withdrew, were subsequently invited to submit prime contractor proposals for the Apollo spacecraft development in 1961. The Technical Assessment Panels began evaluation of contractors' proposals on October 10.
In a memorandum to Abe Silverstein, Director of NASA's Office of Space Flight Programs, George M. Low, Chief of Manned Space Flight, described the formation of a working group on the manned lunar landing program: "It has become increasingly apparent that a preliminary program for manned lunar landings should be formulated. This is necessary in order to provide a proper justification for Apollo, and to place Apollo schedules and technical plans on a firmer foundation.
"In order to prepare such a program, I have formed a small working group, consisting of Eldon Hall, Oran Nicks, John Disher, and myself. This group will endeavor to establish ground rules for manned lunar landing missions; to determine reasonable spacecraft weights; to specify launch vehicle requirements; and to prepare an integrated development plan, including the spacecraft, lunar landing and takeoff system, and launch vehicles. This plan should include a time-phasing and funding picture, and should identify areas requiring early studies by field organizations."
The Technical Assessment Panels presented to the Evaluation Board their findings on the contractors' proposals for feasibility studies of an advanced manned spacecraft. On October 24, the Evaluation Board findings and recommendations were presented to the STG Director.
A staff meeting of STG's Flight Systems Division was held to fix additional design constraints for the in- house design study of the Apollo spacecraft.
Fundamental decisions were made as a result of this and a previous meeting on September 20.
Included in the current Saturn flight schedule were: mid-1961, begin first-stage flights with dummy upper stages; early 1963, begin two-stage flights; late 1963, begin three-stage flights; early 1964, conclude ten-vehicle research and development flight test program.
NASA selected three contractors to prepare individual feasibility studies of an advanced manned spacecraft as part of Project Apollo. The contractors were Convair/Astronautics Division of General Dynamics Corporation, General Electric Company, and The Martin Company.
From 16 bids, Convair, General Electric, and Martin selected to conduct $250,000 study contracts. Meanwhile Space Task Group Langley undertakes its own studies, settling on Apollo CM configuration as actually built by October 1960.
Representatives of the General Electric Company, The Martin Company, and Convair/Astronautics Division of General Dynamics Corporation visited STG to conduct negotiations on the Apollo systems study contracts announced on October 25. The discussions clarified or identified areas not completely covered in company proposals. Contracts were awarded on November 15.
Key staff members of NASA Headquarters and the Commander, U.S. Air Force Research and Development Command, met at the Air Force Ballistic Missile Division, Los Angeles, Calif., to attend briefings and discuss matters of mutual concern.
At an executive session, Air Force and NASA programs of orbital rendezvous, refueling, and descent from orbit were discussed. Long-range Air Force studies on a lunar base were in progress as well as research on more immediate missions, such as rendezvous by an unmanned satellite interceptor for inspection purposes, manned maintenance satellites, and reentry methods. NASA plans for the manned lunar landing mission included the possible use of the Saturn booster in an orbital staging operation employing orbital refueling. Reentry studies beyond Mercury were concentrated on reentry at escape speeds and on a spacecraft configuration capable of aerodynamic maneuvering during reentry.
Lunar atlas prepared for USAF by group under technical direction of G. P. Kuiper was released, an "Orthographic Atlas of the Moon" charted 5,000 base points combined with best available photos and grids.
The Department of the Interior announced that the U.S. Geological Survey would undertake detailed studies of lunar geology as part of a new $205,000 program in astrogeology financed by NASA.
At a meeting, Charles J. Donlan of STG and George M. Low, John H. Disher, Milton W. Rosen, and Elliott Mitchell, all of NASA Headquarters, discussed a plan to set up informal technical liaison groups to broaden the base for inter-Center information exchange on the Apollo program with particular reference to onboard propulsion.
STG formulated a plan for the proposed Apollo Technical Liaison Groups. These Groups were to effect systematic liaison in technical areas related to the Apollo project. The objectives and scope of the plan were as follows:
Charles J. Donlan, Associate Director of STG, invited Langley, Ames, Lewis, and Flight Research Centers, Marshall Space Flight Center, and Jet Propulsion Laboratory to participate in Technical Liaison Groups in accordance with the plan drawn up on November 16.
STG held a meeting at Goddard Space Flight Center to discuss a proposed contract with MIT Instrumentation Laboratory for navigation and guidance support for Project Apollo. The proposed six-month contract for $100,000 might fund studies through the preliminary design stage but not actual hardware. Milton B. Trageser of the Instrumentation Laboratory presented a draft work statement which divided the effort into three parts: midcourse guidance, reentry guidance, and a satellite experiment feasibility study using the Orbiting Geophysical Observatory. STG decided that the Instrumentation Laboratory should submit a more detailed draft of a work statement to form the basis of a contract. In a discussion the next day, Robert G. Chilton of STG and Trageser clarified three points:
A joint briefing on the Apollo and Saturn programs was held at Marshall Space Flight Center MSFC, attended by representatives of STG and MSFC. Maxime A. Faget of STG and MSFC Director Wernher von Braun agreed that a joint STG-MSFC program would be developed to accomplish a manned lunar landing. Areas of responsibility were: MSFC launch vehicle and landing on the moon; STG - lunar orbit, landing, and return to earth.
Smith J. DeFrance, Director of the Ames Research Center, designated Ames working members on six of the nine Apollo Technical Liaison Groups. They were Stanley F. Schmidt (Trajectory Analysis), Clarence A. Syvertson (Configurations and Aerodynamics), G. Allen Smith (Guidance and Control), Glen Goodwin (Heating), Charles A. Hermach (Structures and Materials), and Harald S. Smedal (Human Factors).
Eugene J. Manganiello, Associate Director of the Lewis Research Center, appointed Lewis members to six of the Apollo Technical Liaison Groups. They were Seymour C. Himmel (Trajectory Analysis), Jack B. Esgar (Structures and Materials), Robert E. Tozier (Instrumentation and Communications), Robert F. Seldon (Human Factors), Robert R. Goodman (Mechanical Systems), and Edmund R. Jonash (Onboard Propulsion).
Representatives of Marshall Space Flight Center (MSFC) were assigned to eight of the nine Apollo Technical Liaison Groups by H. H. Koelle, Director, Future Projects Office, MSFC. They were Rudolph F. Hoelker (Trajectory Analysis), Edward L. Linsley (Configurations and Aerodynamics), Werner K. Dahm and Harvey A. Connell (Heating), Erich E. Goerner (Structures and Materials), David M. Hammock and Alexander A. McCool (Onboard Propulsion), Heinz Kampmeier (Instrumentation and Communications), Wilbur G. Thornton (Guidance and Control), and Herman F. Beduerftig (Mechanical Systems). Dual representation on two of the Groups would be necessary because of the division of technical responsibilities within MSFC.
The Director of the Flight Research Center, Paul F. Bikle, nominated Flight Research Center members to eight of the nine Apollo Technical Liaison Groups. They were Donald R. Bellman (Trajectory Analysis), Hubert M. Drake (Configurations and Aerodynamics), Euclid C. Holleman (Guidance and Control), Thomas V. Cooney (Heating), Kenneth C. Sanderson (Instrumentation and Communications), Milton O. Thompson (Human Factors), Perry V. Row (Mechanical Systems) , and Norman E. DeMar (Onboard Propulsion).
A meeting was held by representatives of STG and the MIT Lincoln Laboratory to discuss the scope of the studies to be performed by the Lincoln Laboratory on the ground instrumentation system for the Apollo program. The discussion centered about the draft work statement prepared by STG. In general, those at the meeting agreed that Lincoln Laboratory should conduct an overall analysis of the requirements for the ground system, leading to the formulation of a general systems concept. The study should be completed by the end of December 1961, with interim results available in the middle of 1961 .
First of new series of static firings of Saturn considered only 50 percent successful in 2-second test at MSFC.
Milton B. Trageser of MIT Instrumentation Laboratory transmitted to Charles J. Donlan of STG the outline of a study program on the guidance aspects of Project Apollo. He outlined what might be covered by a formal proposal on the Apollo spacecraft guidance and navigation contract discussed by STG and Instrumentation Laboratory representatives on November 22.
The first technical review of the General Electric Company Apollo feasibility study was held at the contractor's Missile and Space Vehicle Department. Company representatives presented reports on the study so that STG representatives might review progress, provide General Electric with pertinent information from NASA or other sources, and discuss and advise as to the course of the study.
Floyd L. Thompson, Director of the Langley Research Center, assigned Langley members to eight of the Apollo Technical Liaison Groups. They were William H. Michael, Jr. (Trajectory Analysis), Eugene S. Love (Configurations and Aerodynamics), John M. Eggleston (Guidance and Control), Robert L. Trimpi
(Heating), Roger A. Anderson (Structures and Materials), Wilford E. Sivertson, Jr. (Instrumentation and Communications), David Adamson (Human Factors), and Joseph G. Thibodaux, Jr. (Onboard Propulsion).
The Martin Company presented the first technical review of its Apollo feasibility study to STG officials in Baltimore, Md. At the suggestion of STG, Martin agreed to reorient the study in several areas: putting more emphasis on lunar orbits, putting man in the system, and considering landing and recovery in the initial design of the spacecraft.
Brian O. Sparks, Deputy Director of the Jet Propulsion Laboratory (JPL), designated JPL members to serve on six of the nine Apollo Technical Liaison Groups. They were Victor C. Clarke, Jr. (Trajectory Analysis), Edwin Pounder (Configurations and Aerodynamics), James D. Acord (Guidance and Control), John W. Lucas (Heating), William J. Carley (Structures and Materials), and Duane F. Dipprey (Onboard Propulsion),
Representatives of the Langley Research Center briefed members of STG on the lunar orbit method of accomplishing the lunar landing mission.

Convair/Astronautics Division of the General Dynamics Corporation held its first technical review of the Apollo feasibility study in San Diego, Calif. Brief presentations were made by contractor and subcontractor technical specialists to STG representatives. Convair/Astronautics' first approach was oriented toward the modular concept, but STG suggested that the integral spacecraft concept should be investigated.
Associate Administrator of NASA Robert C. Seamans, Jr., and his staff were briefed by Langley Research Center personnel on the rendezvous method as it related to the national space program. Clinton E. Brown presented an analysis made by himself and Ralph W. Stone, Jr., describing the general operational concept of lunar orbit rendezvous for the manned lunar landing. The advantages of this plan in contrast with the earth orbit rendezvous method, especially in reducing launch vehicle requirements, were illustrated. Others discussing the rendezvous were John C. Houbolt, John D. Bird, and Max C. Kurbjun.
The MIT Instrumentation Laboratory submitted a formal proposal to NASA for a study of a navigation and guidance system for the Apollo spacecraft.
The Grumman Aircraft Engineering Corporation began work on a company- funded lunar orbit rendezvous feasibility study.
During a meeting of the Space Exploration Program Council at NASA Headquarters, the subject of a manned lunar landing was discussed. Following presentations on earth orbit rendezvous (Wernher von Braun, Director of Marshall Space Flight Center), lunar orbit rendezvous (John C. Houbolt of Langley Research Center), and direct ascent (Melvyn Savage of NASA Headquarters), the Council decided that NASA should not follow any one of these specific approaches, but should proceed on a broad base to afford flexibility. Another outcome of the discussion was an agreement that NASA should have an orbital rendezvous program which could stand alone as well as being a part of the manned lunar program. A task group was named to define the elements of the program insofar as possible. Members of the group were George M. Low, Chairman, Eldon W. Hall, A. M. Mayo, Ernest O. Pearson, Jr., and Oran W. Nicks, all of NASA Headquarters; Maxime A. Faget of STG; and H. H. Koelle of Marshall Space Flight Center. This group became known as the Low Committee.
The Manned Lunar Landing Task Group (Low Committee) set up by the Space Exploration Program Council was instructed to prepare a position paper for the NASA Fiscal Year 1962 budget presentation to Congress. The paper was to be a concise statement of NASA's lunar program for Fiscal Year 1962 and was to present the lunar mission in term of both direct ascent and rendezvous. The rendezvous program would be designed to develop a manned spacecraft capability in near space, regardless of whether such a technique would be needed for manned lunar landing. In addition to answering such questions as the reason for not eliminating one of the two mission approaches, the Group was to estimate the cost of the lunar mission and the date of its accomplishment, though not in specific terms. Although the decision to land a man on the moon had not been approved, it was to be stressed that the development of the scientific and technical capability for a manned lunar landing was a prime NASA goal, though not the only one. The first meeting of the Group was to be held on January 9.
First meetings of the Apollo Technical Liaison Groups, formed to coordinate NASA inter-Center information exchange.
Three of the Apollo Technical Liaison Groups held their first meetings at STG (Instrumentation and Communications, Mechanical Systems, and Onboard Propulsion.
The Group for Instrumentation and Communications discussed a set of working guidelines on spacecraft instrumentation and communications, tracking considerations, and deep-space communication requirements. Progress of the three Apollo feasibility study contracts was reviewed and the proposed MIT Lincoln Laboratory study on a systems concept for the ground instrumentation and tracking required for the Apollo mission was discussed. Reports of studies were given by members from the NASA Centers. The Group recommendations were :
