NAME: Edgar D. Mitchell
BIRTHPLACE AND DATE: Mitchell was born September 17, 1930, in Hereford.
EDUCATION: Bachelor of Science in industrial management from Carnegie Institute of Technology in 1952. Bachelor of Science in aeronautical engineering from the U.S. Naval Postgraduate School in 1961. Doctorate of Science in aeronautics/astronautics from the Massachusetts Institute of Technology in 1964.
EXPERIENCE: Mitchell entered the Navy in 1952 and was commissioned an ensign a year later. He completed flight training in July 1954 and was assigned to Patrol Squadron 29 deployed to Okinawa. Assigned to a Heavy Attack Squadron in 1957, he flew off the aircraft carriers USS Bon Homme Richard and USS Ticonderoga. He later served as a research pilot with Air Development Squadron 5 and as Chief of Project Management Division of the Navy Field Office for the Manned Orbiting Laboratory project. He graduated first in his class from the Air Force Aerospace Research Pilot School, and served an instructor as the school thereafter. Mitchell was selected as a NASA astronaut in April 1966.
Mitchell was selected as Lunar Module pilot for Apollo 14, which launched on January 31, 1971. The mission was commanded by Alan Shepard and Command Module Pilot was Stuart Roosa. On February 5, Shepard and Mitchell landed their Lunar Module in the Fra Mauro highlands while Roosa orbited overhead in Kitty Hawk. During 33 hours on the surface, Shepard and Mitchell made two outside excursions during which they set up a nuclear-powered science station, collected 42 kg of moon rocks, and obtained core samples of the lunar regolith.
Mitchell long had an interest in extra-sensory perception and while on the lunar surface he conducted unauthorised ESP experiments with a friend in Chicago. Following the Apollo program, he retired from NASA and from the Navy and founded the Institute of Noetic Sciences in an effort to integrate various scientific disciplines into the study of human consciousness. He has written several books, including the 1996's The Way of the Explorer.

On May 19 the crew elected not to make the first of a series of midcourse maneuvers. A second preplanned midcourse correction that adjusted the trajectory to coincide with a July lunar landing trajectory was executed at 3:19 p.m. The maneuver was so accurate that preplanned third and fourth midcourse corrections were canceled. During the translunar coast, five color TV transmissions totaling 72 minutes were made of the spacecraft and the earth.
At 4:49 p.m. EDT on May 21 the spacecraft was inserted into a lunar orbit of 110.4 by 315.5 kilometers. After two revolutions of tracking and ground updates, a maneuver circularized the orbit at 109.1 by 113.9 kilometers. Astronaut Cernan then entered the LM, checked all systems, and returned to the CM for the scheduled sleep period.
On May 22 activation of the lunar module systems began at 11:49 a.m. EDT. At 2:04 p.m. the spacecraft were undocked and at 4:34 p.m. the LM was inserted into a descent orbit. One hour later the LM made a low-level pass at an altitude of 15.4 kilometers over the planned site for the first lunar landing. The test included a test of the landing radar, visual observation of lunar lighting, stereo photography of the moon, and execution of a phasing maneuver using the descent engine. The lunar module returned to dock successfully with the CSM following the eight-hour separation, and the LM crew returned to the CSM.
The LM ascent stage was jettisoned, its batteries were burned to depletion, and it was placed in a solar orbit on May 23. The crew then prepared for the return trip to earth and after 61.5 hours in lunar orbit a service propulsion system TEI burn injected the CSM into a trajectory toward the earth. During the return trip the astronauts made star-lunar landmark sightings, star-earth horizon navigation sightings, and live television transmissions.
Apollo 14 entered lunar orbit at 1:55 a.m. EST on February 4. At 2:41 a.m. the separated S-IVB stage and instrument unit struck the lunar surface 174 kilometers southeast of the planned impact point. The Apollo 12 seismometer, left on the moon in November 1969, registered the impact and continued to record vibrations for two hours.
After rechecking the systems in the LM, astronauts Shepard and Mitchell separated the LM from the CSM and descended to the lunar surface. The Antares landed on Fra Mauro at 4:17 a.m. EST February 5, 9 to 18 meters short of the planned landing point. The first EVA began at 9:53 a.m., after intermittent communications problems in the portable life support system had caused a 49-minute delay. The two astronauts collected a 19.5-kilogram contingency sample; deployed the TV, S-band antenna, American flag, and Solar Wind Composition experiment; photographed the LM, lunar surface, and experiments; deployed the Apollo lunar surface experiments package 152 meters west of the LM and the laser-ranging retroreflector 30 meters west of the ALSEP; and conducted an active seismic experiment, firing 13 thumper shots into the lunar surface.
A second EVA period began at 3:11 a.m. EST February 6. The two astronauts loaded the mobile equipment transporter (MET) - used for the first time - with photographic equipment, tools, and a lunar portable magnetometer. They made a geology traverse toward the rim of Cone Crater, collecting samples on the way. On their return, they adjusted the alignment of the ALSEP central station antenna in an effort to strengthen the signal received by the Manned Space Flight Network ground stations back on earth.
Just before reentering the LM, astronaut Shepard dropped a golf ball onto the lunar surface and on the third swing drove the ball 366 meters. The second EVA had lasted 4 hours 35 minutes, making a total EVA time for the mission of 9 hours 24 minutes. The Antares lifted off the moon with 43 kilograms of lunar samples at 1:48 p.m. EST February 6.
Meanwhile astronaut Roosa, orbiting the moon in the CSM, took astronomy and lunar photos, including photos of the proposed Descartes landing site for Apollo 16.
Ascent of the LM from the lunar surface, rendezvous, and docking with the CSM in orbit were performed as planned, with docking at 3:36 p.m. EST February 6. TV coverage of the rendezvous and docking maneuver was excellent. The two astronauts transferred from the LM to the CSM with samples, equipment, and film. The LM ascent stage was then jettisoned and intentionally crashed on the moon's surface at 7:46 p.m. The impact was recorded by the Apollo 12 and Apollo 14 ALSEPs.
The spacecraft was placed on its trajectory toward earth during the 34th lunar revolution. During transearth coast, four inflight technical demonstrations of equipment and processes in zero gravity were performed.
The CM and SM separated, the parachutes deployed, and other reentry events went as planned, and the Kitty Hawk splashed down in mid-Pacific at 4:05 p.m. EST February 9 about 7 kilometers from the recovery ship U.S.S. New Orleans. The Apollo 14 crew returned to Houston on February 12, where they remained in quarantine until February 26.
All primary mission objectives had been met. The mission had lasted 216 hours 40 minutes and was marked by the following achievements:
One anomaly, an auxiliary propulsion system leak on the S-IVB stage, produced an unpredictable thrust and prevented a final S-IVB targeting maneuver after separation from the CSM. Tracking of the S-IVB ended at 4:04 p.m. EST April 17, when the instrument unit's signal was lost. The stage hit the lunar surface at 4:02 p.m. April 19, 260 kilometers northeast of the target point. The impact was detected by the seismometers left on the moon by the Apollo 12, 14, and 15 missions.
Spacecraft operations were near normal during the coast to the moon. Unexplained light-colored particles from the LM were investigated and identified as shredded thermal paint. Other activities during the translunar coast included a cislunar navigation exercise, ultraviolet photography of the earth and moon, an electrophoresis demonstration, and an investigation of the visual light-flash phenomenon noted on previous flights. Astronaut Duke counted 70 white, instantaneous light flashes that left no after-glow.
Apollo 16 entered a lunar orbit of 314 by 107.7 kilometers at 3:22 p.m. April 19. After separation of LM-11 Orion from CSM 112 Casper, a CSM active rendezvous kept the two vehicles close together while an anomaly discovered on the service propulsion system was evaluated. Tests and analyses showed the redundant system to be still safe and usable if required. The vehicles were again separated and the mission continued on a revised timeline because of the 5 3/4-hour delay.
The lunar module landed with Duke and Young in the moon's Descartes region, about 230 meters northwest of the planned target area at 9:23 p.m. EST April 20. A sleep period was scheduled before EVA.
The first extravehicular activity began at 11:59 a.m. April 21, after the eight-hour rest period. Television coverage of surface activity was delayed until the lunar roving vehicle systems were activated, because the steerable antenna on the lunar module could not be used. The lunar surface experiments packages were deployed, but accidental breaking of the electronics cable rendered the heat flow experiment inoperable. After completing activities at the experiments site, the crew drove the lunar roving vehicle west to Flag Crater, where they performed the planned tasks. The inbound traverse route was just slightly south of the outbound route, and the next stop was Spook Crater. The crew then returned via the experiment station to the lunar module and deployed the solar wind composition experiment. The duration of the extravehicular activity was 7 hours 11 minutes. The distance traveled by the lunar roving vehicle was 4.2 kilometers. The crew collected 20 kilograms of samples.
The second extravehicular traverse, which began at 11:33 a.m. April 22, was south-southeast to a mare-sampling area near the Cinco Craters on Stone Mountain. The crew then drove in a northwesterly direction, making stops near Stubby and Wreck Craters. The last leg of the traverse was north to the experiments station and the lunar module. The second extravehicular activity lasted 7 hours 23 minutes. The distance traveled by the lunar roving vehicle was 11.1 kilometers.
Four stations were deleted from the third extravehicular traverse, which began 30 minutes early at 10:27 a.m. April 23 to allow extra time. The first stop was North Ray Crater, where "House Rock" on the rim of the crater was sampled. The crew then drove southeast to "Shadow Rock." The return route to the LM retraced the outbound route. The third extravehicular activity lasted 5 hours 40 minutes, and the lunar roving vehicle traveled 11.4 kilometers.
Lunar surface activities outside the LM totaled 20 hours 15 minutes for the mission. The total distance traveled in the lunar roving vehicle was 26.7 kilometers. The crew remained on the lunar surface 71 hours 14 minutes and collected 96.6 kilograms of lunar samples.
While the lunar module crew was on the surface, Mattingly, orbiting the moon in the CSM, was obtaining photographs, measuring physical properties of the moon and deep space, and making visual observations. Essentially the same complement of instruments was used to gather data as was used on the Apollo 15 mission, but different areas of the lunar surface were flown over and more comprehensive deep space measurements were made, providing scientific data that could be used to validate findings from Apollo 15 as well as add to the total store of knowledge of the moon and its atmosphere, the solar system, and galactic space.
The LM lifted off from the moon at 8:26 p.m. EST April 23, rendezvoused with the CSM, and docked with it in orbit. Young and Duke transferred to the CSM with samples, film, and equipment, and the LM was jettisoned the next day. LM attitude control was lost at jettison; therefore a deorbit maneuver was not possible and the LM remained in lunar orbit, with an estimated orbital lifetime of about one year.
The particles and fields subsatellite was launched into lunar orbit and normal system operation was noted. However, the spacecraft orbital shaping maneuver was not performed before ejection and the subsatellite was placed in a non-optimum orbit that resulted in a much shorter lifetime than the planned year. Loss of all subsatellite tracking and telemetry data on the 425th revolution (May 29) indicated that the subsatellite had hit the lunar surface.
The mass spectrometer deployment boom stalled during a retract cycle and was jettisoned before transearth injection. The second plane-change maneuver and some orbital science photography were deleted so that transearth injection could be performed about 24 hours earlier than originally planned.
Activities during the transearth coast phase of the mission included photography for a contamination study for the Skylab program and completion of the visual light-flash-phenomenon investigation that had been partially accomplished during translunar coast. A 1-hour 24-minute transearth extravehicular activity was conducted by command module pilot Mattingly to retrieve the film cassettes from the scientific instrument module cameras, inspect the equipment, and expose a microbial-response experiment to the space environment. Two midcourse corrections were made on the return flight to achieve the desired entry interface conditions.
