NAME: Alan L. Bean
BIRTHPLACE AND DATE: Bean was born March 15, 1932, in Wheeler, Texas.
EDUCATION: Bean received a Bachelor of Science degree in aeronautical engineering from the University of Texas in 1955.
EXPERIENCE: As a Navy ROTC student, Bean was commissioned after graduation from college. After completing flight training, he was assigned to a jet attack squadron at the Naval Air Station in Jacksonville, Florida. After a four-year tour, he attended the Navy Test Pilot School and thereafter flew several types of new Navy aircraft as a test pilot.
Bean was selected by NASA in the third group of astronauts in October 1963. He served on the backup crews of Gemini 10 and Apollo 9 missions before assignment as Lunar Module pilot for Apollo 12. On November 19, 1969, Commander Pete Conrad and Bean landed on the Ocean of Storms and became the third and fourth humans to walk on the moon, while Richard Gordon orbited overhead in the Command Module. During two outside excursions they deployed several surface experiments, powered by the first nuclear thermal generator deployed on the moon. Their pinpoint landing allowed them to inspect an unmanned Surveyor spacecraft that landed there two years earlier. They collected and returned 30 kg of rocks and lunar soil for study on Earth.
Bean commanded the second manned Skylab mission, Skylab 3, launched on July 28, 1973. The other crew members were Science Pilot Owen Garriott and Command Module pilot Jack Lousma. They would spend 59 days aboard the space workshop. On the third EVA of the mission, Bean and Garriott installed a new set of gyroscopes to replace failed units. During the course of the mission Earth resources photography, solar astronomy, metals processing and biological experiments were conducted.
Bean retired from the Navy in 1975 but continued with NASA as head of the Astronaut Candidate Operations and Training Group. He retired from NASA in 1981 and thereafter became a space painter of some repute.
Exciting mission with successful docking with Agena, flight up to parking orbit where Gemini 8 Agena is stored. Collins space walks from Gemini to Agena to retrieve micrometeorite package left in space all those months. Loses grip first time, and tumbles head over heels at end of umbilical around Gemini. Package retrieved on second try.
The Gemini X mission began with the launch of the Gemini Atlas-Agena target vehicle from complex 14. The Gemini Agena target vehicle (GATV) attained a near-circular, 162- by 157-nautical-mile orbit. Spacecraft No. 10 was inserted into a 145- by 86-nautical-mile elliptical orbit. Slant range between the two vehicles was very close to the nominal 1000 miles. Major objective of the mission was achieved during the fourth revolution when the spacecraft rendezvoused with the GATV at 5 hours 23 minutes ground elapsed time and docked with it about 30 minutes later. More spacecraft propellant was used to achieve rendezvous than had been predicted, imposing constraints on the remainder of the mission and requiring the development of an alternate flight plan. As a result, several experiments were not completed, and another secondary objective - docking practice - was not attempted. To conserve fuel and permit remaining objectives to be met, the spacecraft remained docked with the GATV for about 39 hours. During this period, a bending mode test was conducted to determine the dynamics of the docked vehicles, standup extravehicular activties (EVA) were conducted, and several experiments were performed. The GATV primary and secondary propulsion systems were used for six maneuvers to put the docked spacecraft into position for rendezvous with the Gemini VIII GATV as a passive target. The spacecraft undocked at 44 hours 40 minutes ground elapsed time, separated from the GATV, and used its own thrusters to complete the second rendezvous some three hours later. At 48 hours and 42 minutes into the flight, a 39-minute period of umbilical EVA began, which included the retrieval of a micrometorite collection package from the Gemini VIII Agena. The hatch was opened a third time about an hour later to jettison extraneous equipment before reentry. After about three hours of stationkeeping, the spacecraft separated from the GATV. At 51 hours 39 minutes ground elapsed time, the crew performed a true anomaly-adjust maneuver to minimize reentry dispersions resulting from the retrofire maneuver. The retrofire maneuver was initiated at 70 hours 10 minutes after liftoff, during the 43rd revolution. The spacecraft landed within sight of the prime recovery ship, the aircraft carrier Guadalcanal, some 5 km from the planned landing point on July 21.
Apollo 9 (AS-504), the first manned flight with the lunar module (LM-3), was launched from Pad A, Launch Complex 39, KSC, on a Saturn V launch vehicle at 11:00 a.m. EST March 3. Originally scheduled for a February 28 liftoff, the launch had been delayed to allow crew members James A. McDivitt, David R. Scott, and Russell L. Schweickart to recover from a mild virus respiratory illness. Following a normal launch phase, the S-IVB stage inserted the spacecraft into an orbit of 192.3 by 189.3 kilometers. After post-insertion checkout, CSM 104 separated from the S-IVB, was transposed, and docked with the LM. At 3:08 p.m. EST, the docked spacecraft were separated from the S-IVB, which was then placed on an earth-escape trajectory.
On March 4 the crew tracked landmarks, conducted pitch and roll yaw maneuvers, and increased the apogee by service propulsion system burns.
On March 5 McDivitt and Schweickart entered the LM through the docking tunnel, evaluated the LM systems, transmitted the first of two series of telecasts, and fired the LM descent propulsion system. They then returned to the CM.
McDivitt and Schweickart reentered the LM on March 6. After transmitting a second telecast, Schweickart performed a 37-minute extravehicular activity (EVA), walking between the LM and CSM hatches, maneuvering on handrails, taking photographs, and describing rain squalls over KSC.
On March 7, with McDivitt and Schweickart once more in the LM, Scott separated the CSM from the LM and fired the reaction control system thrusters to obtain a distance of 5.5 kilometers between the two spacecraft. McDivitt and Schweickart then performed a lunar-module active rendezvous. The LM successfully docked with the CSM after being up to 183.5 kilometers away from it during the six-and-one-half-hour separation. After McDivitt and Schweickart returned to the CSM, the LM ascent stage was jettisoned.
During the remainder of the mission, the crew tracked Pegasus III, NASA's meteoroid detection satellite that had been launched July 30, 1965; took multispectral photos of the earth; exercised the spacecraft systems; and prepared for reentry.
The Apollo 9 CM splashed down in the Atlantic 290 kilometers east of the Bahamas at 12:01 p.m. EST. The crew was picked up by helicopter and flown to the recovery ship U.S.S. Guadalcanal within one hour after splashdown. Primary objectives of the flight were successfully accomplished.
Apollo 12 (AS-507)-with astronauts Charles Conrad, Jr., Richard F. Gordon, Jr., and Alan L. Bean as the crewmen-was launched from Pad A, Launch Complex 39, KSC, at 11:22 a.m. EST November 14. Lightning struck the space vehicle twice, at 36.5 seconds and 52 seconds into the mission. The first strike was visible to spectators at the launch site. No damage was done. Except for special attention given to verifying all spacecraft systems because of the lightning strikes, the activities during earth-orbit checkout, translunar injection, and translunar coast were similar to those of Apollo 10 and Apollo 11.
During the translunar coast astronauts Conrad and Bean transferred to the LM one-half hour earlier than planned in order to obtain full TV coverage through the Goldstone tracking station. The 56-minute TV transmission showed excellent color pictures of the CSM, the intravehicular transfer, the LM interior, the earth, and the moon.
At 10:47 p.m. EST, November 17, the spacecraft entered a lunar orbit of 312.6 x 115.9 kilometers. A second service propulsion system burn circularized the orbit with a 122.5-kilometer apolune and a 100.6-kilometer perilune. Conrad and Bean again transferred to the LM, where they perfomed housekeeping chores, a voice and telemetry test, and an oxygen purge system check. They then returned to the CM.
Conrad and Bean reentered the LM, checked out all systems, and at 10:17 p.m. EST on November 18 fired the reaction control system thrusters to separate the CSM 108 (the Yankee Clipper) from the LM-6 (the Intrepid). At 1:55 a.m. EST November 19, the Intrepid landed on the moon's Ocean of Storms, about 163 meters from the Surveyor III spacecraft that had landed April 19, 1967. Conrad, shorter than Neil Armstrong (first man on the moon, July 20), had a little difficulty negotiating the last step from the LM ladder to the lunar surface. When he touched the surface at 6:44 a.m. EST November 19, he exclaimed, "Whoopee! Man, that may have been a small step for Neil, but that's a long one for me."
Bean joined Conrad on the surface at 7:14 a.m. They collected a 1.9-kilogram contingency sample of lunar material and later a 14.8-kilogram selected sample. They also deployed an S-band antenna, solar wind composition experiment, and the American flag. An Apollo Lunar Surface Experiments Package with a SNAP-27 atomic generator was deployed about 182 meters from the LM. After 3 hours 56 minutes on the lunar surface, the two astronauts entered the Intrepid to rest and check plans for the next EVA.
The astronauts again left the LM at 10:55 p.m. EST November 19. During the second EVA, Conrad and Bean retrieved the lunar module TV camera for return to earth for a failure analysis, obtained photographic panoramas, core and trench samples, a lunar environment sample, and assorted rock, dirt, bedrock, and molten samples. The crew then examined and retrieved parts of Surveyor III, including the TV camera and soil scoop. After 3 hours 49 minutes on the lunar surface during the second EVA, the two crewmen entered the LM at 2:44 a.m. EST November 20. Meanwhile astronaut Gordon, orbiting the moon in the Yankee Clipper, had completed a lunar multispectral photography experiment and photographed proposed future landing sites.
At 9:26 a.m. EST November 20, after 31 hours 31 minutes on the moon, Intrepid successfully lifted off with 34.4 kilograms of lunar samples. Rendezvous maneuvers went as planned. The LM docked with the CSM at 12:58 p.m. November 20. The last 24 minutes of the rendezvous sequence was televised. After the crew transferred with the samples, equipment, and film to the Yankee Clipper, the Intrepid was jettisoned and intentionally crashed onto the lunar surface at 5:17 p.m. November 20, 72.2 kilometers southeast of Surveyor III. The crash produced reverberations that lasted about 30 minutes and were detected by the seismometer left on the moon.
At 3:49 p.m. EST November 21, the crew fired the service propulsion system engine, injecting the CSM into a transearth trajectory after 89 hours 2 minutes in lunar orbit. During the transearth coast, views of the receding moon and the interior of the spacecraft were televised, and a question and answer session with scientists and the press was conducted.
Parachute deployment and other reentry events occurred as planned. The CM splashed down in mid-Pacific at 3:58 p.m. EST November 24, 7.25 kilometers from the recovery ship, U.S.S. Hornet. The astronauts, wearing flight suits and biological face masks, were airlifted by helicopter from the CM to the recovery ship, where they entered the mobile quarantine facility. They would remain in this facility until arrival at the Lunar Receiving Laboratory, MSC. The Apollo 12 mission objectives were achieved and the experiments successfully accomplished.
Explored lunar surface near LM and deployed ALSEP unmanned scientific station equipment.
Moonwalk to Surveyor 3, which had landed two years before. Recovered parts of Surveyor 3 which seemed to show that Earth bacteria could survive for that period in space and be revived.
Threw excess equipment out of LM before lift-off.
Continued maintenance of the Skylab space station and extensive scientific and medical experiments. Installed twinpole solar shield on EVA; performed major inflight maintenance; doubled record for length of time in space. Completed 858 Earth orbits and 1,081 hours of solar and Earth experiments; three EVAs totalled 13 hours, 43 minutes.
The space vehicle, consisting of a modified Apollo command and service module payload on a Saturn IB launch vehicle, was inserted into a 231.3 by 154.7 km orbit. Rendezvous maneuvers were performed during the first five orbits as planned. During the rendezvous, the CSM reaction control system forward firing engine oxidizer valve leaked. The quad was isolated. Station-keeping with the Saturn Workshop began approximately 8 hours after liftoff, with docking being performed about 30 minutes later.
Replaced film cartridges for solar camera.
This flight marked the culmination of the Apollo-Soyuz Test Project, a post-moon race 'goodwill' flight to test a common docking system for space rescue. 15 July 1975 began with the flawless launch of Soyuz 19. Apollo followed right on schedule. Despite a stowaway - a 'super Florida mosquito' - the crew accomplished a series of rendezvous manoeuvres over the next day resulting in rendezvous with Soyuz 19. At 11:10 on 17 July the two spacecraft docked. The crew members rotated between the two spacecraft and conducted various mainly ceremonial activities. Stafford spent 7 hours, 10 minutes aboard Soyuz, Brand 6:30, and Slayton 1:35. Leonov was on the American side for 5 hours, 43 minutes, while Kubasov spent 4:57 in the command and docking modules.
After being docked for nearly 44 hours, Apollo and Soyuz parted for the first time and were station-keeping at a range of 50 meters. The Apollo crew placed its craft between Soyuz and the sun so that the diameter of the service module formed a disk which blocked out the sun. This artificial solar eclipse, as viewed from Soyuz, permitted photography of the solar corona. After this experiment Apollo moved towards Soyuz for the second docking.
Three hours later Apollo and Soyuz undocked for the second and final time. The spacecraft moved to a 40 m station-keeping distance so that the ultraviolet absorption (UVA MA-059) experiment could be performed. This was an effort to more precisely determine the quantities of atomic oxygen and atomic nitrogen existing at such altitudes. Apollo, flying out of plane around Soyuz, projected monochromatic laser-like beams of light to retro-reflectors mounted on Soyuz. On the 150-meter phase of the experiment, light from a Soyuz port led to a misalignment of the spectrometer, but on the 500-meter pass excellent data were received; on the 1,000-meter pass satisfactory results were also obtained.
With all the joint flight activities completed, the ships went on their separate ways. On 20 July the Apollo crew conducted earth observation, experiments in the multipurpose furnace (MA-010), extreme ultraviolet surveying (MA-083), crystal growth (MA-085), and helium glow (MA-088). On 21 July Soyuz 19 landed safely in Kazakhstan. Apollo continued in orbit on 22-23 July to conduct 23 independent experiments - including a doppler tracking experiment (MA-089) and geodynamics experiment (MA-128) designed to verify which of two techniques would be best suited for studying plate tectonics from earth orbit.
After donning their space suits, the crew vented the command module tunnel and jettisoned the docking module. The docking module would continue on its way until it re-entered the earth's atmosphere and burned up in August 1975. Apollo splashed down about 7,300 meters from the recovery ship New Orleans. However the flight of the last Apollo spacecraft was marred by the fact that the crew almost perished while the capsule was descending under its parachute.
A failure in switchology led the automatic landing sequence to be not armed at the same time the reaction control system was still active. When the Apollo hadn't begun the parachute deployment sequence by 7,000 metres altitude, Brand hit the manual switches for the apex cover and the drogues. The manual deployment of the drogue chutes caused the CM to sway, and the reaction control system thrusters worked vigorously to counteract that motion. When the crew finally armed the automatic ELS 30 seconds later, the thruster action terminated.
During that 30 seconds, the cabin was flooded with a mixture of toxic unignited propellants from the thrusters. Prior to drogue deployment, the cabin pressure relief valve had opened automatically, and in addition to drawing in fresh air it also brought in unwanted gases being expelled from the roll thrusters located about 0.6 meter from the relief valve. Brand manually deployed the main parachutes at about 2,700 meters despite the gas fumes in the cabin.
By the time of splashdown, the crew was nearly unconscious from the fumes, Stafford managed to get an oxygen mask over Brand's face. He then began to come around. When the command module was upright in the water, Stafford opened the vent valve, and with the in-rush of air the remaining fumes disappeared. The crew ended up with a two-week hospital stay in Honolulu. For Slayton, it also meant the discovery of a small lesion on his left lung and an exploratory operation that indicated it was a non-malignant tumour.
