Official NASA Biography as of June 2016:David R. Scott (Colonel, USAF, Ret.)
NASA Astronaut (former)

PERSONAL DATA: Born June 6, 1932, in San Antonio, Texas. Married. Two children. Recreational interests include swimming, handball, skiing, and photography.

EDUCATION: Graduated from Western High School, Washington, D.C.; received a Bachelor of Science degree from the United States Military Academy and the degrees of Master of Science in Aeronautics and Astronautics and Engineer in Aeronautics and Astronautics from the Massachusetts Institute of Technology; awarded an Honorary Doctorate of Astronautical Science from the University of Michigan in 1971. He has graduated from the Air Force Experimental Test Pilots School and Aerospace Research Pilots School.

ORGANIZATIONS: Scott is a fellow of the American Astronautical Society, Associate fellow of the American Institute of Aeronautics and Astronautics, and member of the Society of Experimental Test Pilots, and Tau Beta Pi, Sigma Xi and Sigma Gamma Tau.

SPECIAL HONORS: Two NASA Distinguished Service Medals, the NASA Exceptional Service Medal, two Air Force Distinguished Service Medals, the Air Force Distinguished Flying Cross, the Air Force Association's David C. Schilling Trophy and the Robert J. Collier Trophy for 1971.

EXPERIENCE: Scott graduated fifth in a class of 633 at West Point and subsequently chose an Air Force career. He completed pilot training at Webb Air Force Base, Texas, in 1955 and then reported for gunnery training at Laughlin Air Force Base, Texas, and Luke Air Force Base, Arizona.

He was assigned to the 32d Tactical Fighter squadron at Soesterberg Air Base (RNAF), Netherlands, from April 1956 to July 1960. Upon completing this tour of duty, he returned to he United States for study at the Massachusetts Institute of Technology.

He retired from the Air Force in March 1975 with the rank of Colonel and over 5600 hours of flying time.

NASA EXPERIENCE: Scott was one of the third group of astronauts named by NASA in October 1963.

On March 16, 1966, he and command pilot Neil Armstrong were launched into space on the Gemini 8 mission--a flight originally scheduled to last three days but terminated early due to a malfunctioning thruster. The crew performed the first successful docking of two vehicles in space and demonstrated great piloting skill in overcoming the thruster problem and bringing the spacecraft to a safe landing.

Scott served as command module pilot for Apollo 9, March 3-13, 1969. This was the third manned flight in the Apollo series, the second to be launched by a Saturn V, and the first to complete a comprehensive earth-orbital qualification and verification test of a "fully configured Apollo spacecraft." The ten-day flight provided vital information previously not available on the operational performance, stability, and reliability of lunar module propulsion and life support systems. Highlight of this evaluation was completion of a critical lunar-orbit rendezvous simulation and subsequent docking, initiated by James McDivitt and Russell Schweickart from within the lunar module at a separation distance which exceeded 100 miles from the command/service module piloted by Scott. The crew also demonstrated and confirmed the operational feasibility of crew transfer and extravehicular activity techniques and equipment, with Schweickart completing a 46-minute EVA outside the lunar module. During this period, Dave Scott completed a 1-hour stand-up EVA in the open command module hatch photographing Schweickart's activities and also retrieving thermal samples from the command module exterior. Apollo 9 splashed down less than four miles from the helicopter carrier USS GUADALCANAL.

In his next assignment, Scott was designated backup spacecraft commander for Apollo 12.

He made his third space flight as spacecraft commander of Apollo 15, July 26 - August 7, 1971. His companions on the flight were Alfred M. Worden (command module pilot) and James B. Irwin (lunar module pilot). Apollo 15 was the fourth manned lunar landing mission and the first to visit and explore the moon's Hadley Rille and Apennine Mountains which are located on the southeast edge of the Mare Imbrium (Sea of Rains). The lunar module, "Falcon," remained on the lunar surface for 66 hours and 54 minutes (setting a new record for lunar surface stay time) and Scott and Irwin logged 18 hours and 35 minutes each in extravehicular activities conducted during three separate excursions onto the lunar surface. Using "Rover-1" to transport themselves and their equipment along portions of Hadley Rille and the Apennine Mountains, Scott and Irwin performed a selenological inspection and survey of the area and collected 180 pounds of lunar surface materials. They deployed an ALSEP package which involved the emplacement and activation of surface experiments, and their lunar surface activities were televised using a TV camera which was operated remotely by ground controllers stationed in the mission control center located at Houston, Texas. Other Apollo 15 achievements include: largest payloads ever placed into earth and lunar orbits; first scientific instrument module bay flown and operated on an Apollo spacecraft; longest distance traversed on lunar surface; first use of a lunar surface navigation device (mounted on Rover-1); first subsatellite launched in lunar orbit; and first extravehicular (EVA) from a command module during transearth coast. The latter feat performed by Worden during three excursions to "Endeavour's" SIM-bay where he retrieved film cassettes from the panoramic and mapping cameras and reported his personal observations of the general condition of equipment housed there. Apollo 15 concluded with a Pacific Ocean splashdown and subsequent recovery by the USS OKINAWA.

He has logged 546 hours and 54 minutes in space, of which 20 hours and 46 minutes were in Extravehicular Activity. He is only one of three Astronauts who have flown both earth orbital and lunar Apollo Missions.

Official Biography

NAME: David R. Scott

BIRTHPLACE AND DATE: Scott was born June 6, 1932, in San Antonio, Texas.

EDUCATION: Scott received a Bachelor of Science degree from the U.S. Military Academy in 1954, standing fifth in a class of 633, and the degrees of Master of Science in Aeronautics and Astronautics and Engineer in Aeronautics and Astronautics from Massachusetts Institute of Technology in 1962.

EXPERIENCE: After graduation from the US Military Academy in 1954, he entered the US Air Force. He later graduated from the Experimental Test Pilot School and Aerospace Research Pilot School at Edwards Air Force Base, California.

NASA selected him as an astronaut in 1963. On March 16, 1966 Scott and Neil Armstrong aboard Gemini 8 conducted the first docking in space. But shortly after the Gemini and the Agena docked, the craft began spinning out of control. Armstrong disengaged from the Agena, thinking the problem was on there, but the tumbling worsened. It was later determined that it was one of 16 Gemini thrusters that was stuck. Unable to stop the spin with the main thrusters, Armstrong shut down the Gemini's reaction control system and brought the craft under control using a second set of 16 thrusters intended only for use on re-entry. Mission Control ordered Armstrong and Scott to cut the flight short and they splashed down in a contingency recovery area in the western Pacific. Scott missed out on his planned space walk.

Scott's next flight was Apollo 9, a ten day earth orbit test of the first complete set of Apollo hardware. Commander James A. McDivitt and Lunar Module pilot Russell L. Schweickart accompanied Scott on the March 3, 1969 launch. McDivitt and Schweickart took the Lunar Module on its first manned test, flying 182 km away from Scott in the Command Module before flying back to a rendezvous and docking.

Scott was in command of the fourth lunar landing, Apollo 15, launched on July 26, 1971,. He and James B. Irwin flew their Lunar Module to the moon's surface while Alfred M. Worden waited in the Command Module in lunar orbit. This was the first extended scientific expedition to the moon and the first to use the Lunar Rover. In three separate excursions over three days they explored the most spectacular Apollo landing site, a narrow valley hemmed in on three sides by the 4,500 m Apennine Mountains and on the fourth by a 2 km wide canyon, Hadley Rille. They returned with 77 kg of rocks, having left behind an ALSEP science station for continued monitoring of the lunar environment.

Following the moon flight, Scott held administrative posts with NASA, including Director of the Dryden Flight Research Center at Edwards Air Force Base. He retired from the Air Force in 1975 as a colonel. He was later President of Scott Science and Technology.

    The group was selected to provide crew members for planned Apollo missions (then planned as 4 Saturn I missions in 1965, 2-4 Saturn IB missions in 1966, 6 Saturn V missions from 1967).. Qualifications: Qualified jet pilot with minimum 1,000 flight-hours, bachleor's degree in engineering or physical or biological sciences, under 35 years old, under 183 cm height, excellent health. US citizen.. There were 271 applications, 200 from civilians (including two women) and 71 from military pilots (including two African-Americans). President Kennedy pushed for NASA to appoint a black astronaut, but neither of the applicants met the test pilot requirements. Bobby Kennedy arranged for one of these, USAF Captain Edward Dwight, to be enrolled in the USAF Test Pilot school. He graduated, and then had the necessary qualifications. He was 28 years old, an engineering school graduate, and a B-57 bomber command pilot with 2,000 hours flying time. However NASA did not find him as well qualified as other candidates, and he was not among the 32 chosen for final physical and mental tests.

    From these 32, the final 14 were selected. Of them, four would die (two in a T-38 crash, one in a car crash, and one in the Apollo 204 ground fire) before flying in space. All of the ten remaining would fly in the Apollo program.

  • Gemini 8 - . Call Sign: Gemini 8. Crew: Armstrong, Scott. Backup Crew: Conrad, Gordon. Payload: Gemini SC8. Mass: 3,788 kg (8,351 lb). Nation: USA. Related Persons: Armstrong, Conrad, Gordon, Scott. Agency: NASA Houston. Program: Gemini. Class: Manned. Type: Manned spacecraft. Flight: Gemini 8. Spacecraft: Gemini. Duration: 0.45 days.

    The Atlas-Agena target vehicle for the Gemini VIII mission was successfully launched from KSC Launch Complex 14 at 10 a.m. EST March 16. The Gemini VIII spacecraft followed from Launch Complex 19 at 11:41 a.m., with command pilot Neil A. Armstrong and pilot David R. Scott aboard. The spacecraft and its target vehicle rendezvoused and docked, with docking confirmed 6 hours 33 minutes after the spacecraft was launched. This first successful docking with an Agena target vehicle was followed by a major space emergency. About 27 minutes later the spacecraft-Agena combination encountered unexpected roll and yaw motion. A stuck thruster on Gemini put the docked assembly into a wild high speed gyration. Near structural limits and blackout, Armstrong undocked, figuring the problem was in the Agena, which only made it worse. The problem arose again and when the yaw and roll rates became too high the crew shut the main Gemini reaction control system down and activated and used both rings of the reentry control system to reduce the spacecraft rates to zero. This used 75% of that system's fuel. Although the crew wanted to press on with the mission and Scott's planned space walk, ground control ordered an emergency splashdown in the western Pacific during the seventh revolution. The spacecraft landed at 10:23 p.m. EST March 16 and Armstrong and Scott were picked up by the destroyer U.S.S. Mason at 1:37 a.m. EST March 17. Although the flight was cut short by the incident, one of the primary objectives - rendezvous and docking (the first rendezvous of two spacecraft in orbital flight) - was accomplished.

    Primary objectives of the scheduled three-day mission were to rendezvous and dock with the Gemini Agena target vehicle (GATV) and to conduct extravehicular activities. Secondary objectives included rendezvous and docking during the fourth revolution, performing docked maneuvers using the GATV primary propulsion system, executing 10 experiments, conducting docking practice, performing a rerendezvous, evaluating the auxiliary tape memory unit, demonstrating controlled reentry, and parking the GATV in a 220-nautical mile circular orbit. The GATV was inserted into a nominal 161-nautical mile circular orbit, the spacecraft into a nominal 86 by 147-nautical mile elliptical orbit. During the six hours following insertion, the spacecraft completed nine maneuvers to rendezvous with the GATV. Rendezvous phase ended at 5 hours 58 minutes ground elapsed time, with the spacecraft 150 feet from the GATV and no relative motion between the two vehicles. Stationkeeping maneuvers preceded docking, which was accomplished at 6 hours 33 minutes ground elapsed time. A major problem developed 27 minutes after docking, when a spacecraft orbit attitude and maneuver system (OAMS) thruster malfunctioned. The crew undocked from the GATV and managed to bring the spacecraft under control by deactivating the OAMS and using the reentry control system (RCS) to reduce the spacecraft's rapid rotation. Premature use of the RCS, however, required the mission to be terminated early. The retrofire sequence was initiated in the seventh revolution, followed by nominal reentry and landing in a secondary recovery area in the western Pacific Ocean. The spacecraft touched down less than 10 km from the planned landing point. The recovery ship, the destroyer Leonard Mason, picked up both crew and spacecraft some three hours later. Early termination of the mission precluded achieving all mission objectives, but one primary objective - rendezvous and docking - was accomplished. Several secondary objectives were also achieved: rendezvous and docking during the fourth revolution, evaluating the auxiliary tape memory unit, demonstrating controlled reentry, and parking the GATV. Two experiments were partially performed.

    Before the Apollo 1 fire, it was planned that McDivitt's crew would conduct the Apollo D mission - a first manned test in earth orbit of the Lunar Module. Separate Saturn IB launches would put Apollo Block II CSM 101 / AS-207 and Lunar Module LM-2 / AS-208 into earth orbit. The crew would then rendezvous and dock with the lunar module and put it through its paces. After the fire, it was decided to launch the mission on a single Saturn V as Apollo 9.

Period: 88.60 min.

    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.

    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.

    Apollo 15 (AS-510) with astronauts David R. Scott, Alfred M. Worden, and James B. Irwin aboard was launched from Pad A, Launch Complex 39, KSC, at 9:34 a.m. EDT July 26. The spacecraft and S-IVB combination was placed in an earth parking orbit 11 minutes 44 seconds after liftoff. Activities during earth orbit and translunar injection (insertion into the trajectory for the moon) were similar to those of previous lunar landing missions. Translunar injection was at about 12:30 p.m., with separation of the CSM from the LM/S-IVB/IU at 12:56 p.m. At 1:08 p.m., onboard color TV showed the docking of the CSM with the LM.

    S-IVB auxiliary propulsion system burns sent the S-IVB/IU stages toward the moon, where they impacted the lunar surface at 4:59 p.m. EDT July 29. The point of impact was 188 kilometers northeast of the Apollo 14 landing site and 355 kilometers northeast of the Apollo 12 site. The impact was detected by both the Apollo 12 and Apollo 14 seismometers, left on the moon in November 1969 and February 1971.

    After the translunar coast, during which TV pictures of the CSM and LM interiors were shown and the LM communications and other systems were checked, Apollo 15 entered lunar orbit at 4:06 p.m. EDT July 29.

    The LM-10 Falcon, with astronauts Scott and Irwin aboard, undocked and separated from the Endeavor (CSM 112) with astronaut Worden aboard. At 6:16 p.m. EDT July 30, the Falcon landed in the Hadley-Apennine region of the moon 600 meters north-northwest of the proposed target. About two hours later, following cabin depressurization, Scott performed a 33-minute standup EVA in the upper hatch of the LM, during which he described and photographed the landing site.

    The first crew EVA on the lunar surface began at 9:04 a.m. July 31. The crew collected and stowed a contingency sample, unpacked the ALSEP and other experiments, and prepared the lunar roving vehicle (LRV) for operations. Some problems were encountered in the deployment and checkout of the LRV, used for the first time, but they were quickly resolved. The first EVA traverse was to the Apennine mountain front, after which the ALSEP was deployed and activated, and one probe of a Heat Flow experiment was emplaced. A second probe was not emplaced until EVA-2 because of drilling difficulties. The first EVA lasted 6 hours 33 minutes.

    At 7:49 a.m. EDT August 1, the second EVA began. The astronauts made a maintenance check on the LRV and then began the second planned traverse of the mission. On completion of the traverse, Scott and Irwin completed the placement of heat flow experiment probes, collected a core sample, and deployed the American flag. They then stowed the sample container and the film in the LM, completing a second EVA of 7 hours 12 minutes.

    The third EVA began at 4:52 a.m. August 2, included another traverse, and ended 4 hours 50 minutes later, for a total Apollo 15 lunar surface EVA time of 18 hours 35 minutes.

    While the lunar module was on the moon, astronaut Worden completed 34 lunar orbits in the CSM operating scientific instrument module experiments and cameras to obtain data concerning the lunar surface and environment. X-ray spectrometer data indicated richer abundance of aluminum in the highlands, especially on the far side, but greater concentrations of magnesium in the maria.

    Liftoff of the ascent stage of the LM, the first one to be televised, occurred at 1:11 p.m. EDT August 2. About two hours later the LM and CSM rendezvoused and docked, and film, equipment, and 77 kilograms of lunar samples were transferred from the LM to the CSM. The ascent stage was jettisoned and hit the lunar surface at 11:04 p.m. EDT August 2. Its impact was recorded by the Apollo 12, Apollo 14, and Apollo 15 seismometers, left on the moon during those missions. Before leaving the lunar orbit, the spacecraft deployed a subsatellite, at 4:13 p.m. August 4, in an orbit of 141.3 by 102 kilometers. The satellite would measure interplanetary and earth magnetic fields near the moon. It also carried charged-particle sensors and equipment to detect variations in lunar gravity caused by mascons (mass concentrations).

    A transearth injection maneuver at 5:23 p.m. August 4 put the CSM on an earth trajectory. During the transearth coast, astronaut Worden performed an inflight EVA beginning at 11:32 a.m. August 5 and lasting for 38 minutes 12 seconds. He made three trips to the scientific instrument module (SIM) bay of the SM, twice to retrieve cassettes and once to observe the condition of the instruments in the SIM bay.

    CM and SM separation, parachute deployment, and other reentry events went as planned, but one of the three main parachutes failed, causing a hard but safe landing. Splashdown - at 4:45 p.m. EDT (20:45 GMT), after 12 days 7 hours 12 minutes from launch - was 530 kilometers north of Hawaii and 10 kilometers from the recovery ship U.S.S. Okinawa. The astronauts were carried to the ship by helicopter, and the CM was retrieved and placed on board. All primary mission objectives had been achieved.
