After several tests indicating the model was too small to permit refinements, Goddard decided to build a rocket twenty-fold larger. During 1926 a new tower was built, and flow regulators, multiple liquid injection into large combustion chambers, means for measurement of pressure and lifting force, electrically fired igniter, and turntable for rotation were developed.

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. References: 16 .
A NASA Headquarters working group, headed by Bernard Maggin, completed a staff paper presenting arguments for establishing an integrated research, development, and applied orbital operations program at an approximate cost of $1 billion through 1970. The group identified three broad categories of orbital operations: inspection, ferry, and orbital launch. It concluded that future space programs would require an orbital operations capability and that the development of an integrated program, coordinated with Department of Defense, should begin immediately. The group recommended that such a program, because of its scope and cost, be independent of other space programs and that a project office be established to initiate and implement the program.
STG completed the first draft of "Project Apollo, Phase A, General Requirements for a Proposal for a Manned Space Vehicle and System" (Statement of Work), an early step toward the spacecraft specification. A circumlunar mission was the basis for planning. References: 16 .
Alan Shepard first American in space, less than a month after Gagarin and only on a 15 minute suborbital flight. Only manned flight with original capsule (tiny round porthole and periscope a la Vostok). If NASA had not listened to Von Braun, Shepard would have flown on the MR-BD flight of 24 March, beating Gagarin by three weeks and becoming the first man in space (though not in orbit). Shepard's capsule reached an altitude of 115.696 miles, range of 302 miles,and speed of 5,100 miles per hour. He demonstrated control of a vehicle during weightlessness and high G stresses. Recovery operations were perfect; there was no damage to the spacecraft; and Astronaut Shepard was in excellent condition. Additional Details: Mercury MR-3. References: 5 , 16 , 26 , 33 , 59 , 60 .
Some significant features of a revised Apollo and AAP-integrated program plan were: CSM would be available to support the first four AAP launches; AAP-1/ AAP-2 in early 1969 were to accomplish OWS objectives; AAP-3/AAP-4 in mid-1969 were to accomplish the 56-day ATM objectives in conjunction with reuse of the OWS. Two additional AAP flights were planned for 1969 to revisit the OWS and the ATM using refurbished command modules flown initially on Earth-orbit Apollo flights in 1968. AAP missions planned for low Earth orbit during 1970 would utilize two dual launches (one manned CSM and one unmanned experiment module per dual launch) and two single-launch, long-duration CSM to establish and maintain near- continuous operation of the OWS cluster and a second ATM.

ASPO reported a recent manned-test abort of the portable life support system had been caused by a nonfunctional lithium hydroxide canister. Quality control procedures were in existence and if properly implemented would have precluded the abort incident. To prevent similar incidents from occurring, all manned-test and flight equipment would be accompanied by complete documentation, would be visually inspected, and would be certified by quality assurance personnel before use.

The Centaur RL-10B-2 second stage engine's combustion chamber ruptured at the beginning of the second burn. The hot gases already in the chamber vented, putting the stage/spacecraft assembly into an uncontrollable tumble. The Orion 3 communications satellite ended up in a useless parking orbit of 162 km x 1378 km x 29.5 deg. It was to have served the Asia-Pacific region for Loral Orion with 33 Ku-band and 10 C-band transponders.
