Evans, Ronald Ellwin Jr 'Ron' (1933-1990) American pilot astronaut. Flew combat missions over Vietnam. Flew on Apollo 17.

NAME: Ronald E. Evans

BIRTHPLACE AND DATE: Evans was born November 10, 1933, in St. Francis, Kansas.

EDUCATION: Bachelor of Science degree in electrical engineering from the University of Kansas in 1956. Master of Science in aeronautical engineering from the U.S. Naval Postgraduate School in 1964.

EXPERIENCE: Evans entered the Navy after graduation and completed flight training and served aboard aircraft carriers in the Western Pacific. In 1961 - 1962 he was a combat flight instructor for F-8 fighter pilots. Thereafter he flew combat missions in the F-8 for seven months from the carrier USS Ticonderoga.

NASA selected Evans as an astronaut in April 1966. He was backup Command Module pilot on Apollo 14 and flew as Command Module pilot on Apollo 17, with Commander Gene Cernan and Lunar Module pilot Harrison H. (Jack) Schmitt. This final Apollo lunar mission was launched on December 7, 1972. While Cernan and Schmitt drove their Lunar Rover across the surface in three separate excursions, Evans maintained a solo vigil in the Command Module, mapping the moon from lunar orbit with cameras and scientific instruments. After the Lunar Module docked up with Command Module the astronauts spent two more days in lunar orbit to collect additional data. During voyage back to Earth, Evans took a 1 hour-6-minute deep space walk to retrieve film and data tapes from the Command Module instrument bay. The longest Apollo lunar mission - 301 hours, 51 minutes - ended with a December 19 splashdown in the Pacific Ocean.

Evans served as backup Command Module pilot for the 1975 joint U.S.-Russian space mission, Apollo-Soyuz Test Project, and was thereafter involved in development of the Space Shuttle. He retired as a captain from the Navy in 1975 and from NASA in March 1977. He was later Director of Space Systems Marketing for Sperry Flight Systems. He died April 6, 1990, in Scottsdale, Arizona, of a heart attack.

Payload: Apollo CSM 110 / Apollo LM 8 / ALSEP / S-IVB-509. Mass: 29,230 kg (64,440 lb). Nation: USA. Related Persons: Mitchell; Roosa; Shepard; Cernan; Engle; Evans; Chapman; McCandless; Pogue. Agency: NASA Houston. Program: Apollo. Class: Moon. Type: Manned lunar spacecraft. Flight: Apollo 14. Spacecraft: Apollo CSM. Duration: 9.00 days. Decay Date: 1971-02-09 . USAF Sat Cat: 4900 . COSPAR: 1971-008A. Apogee: 183 km (113 mi). Perigee: 170 km (100 mi). Inclination: 31.1200 deg. Period: 88.18 min. The Apollo 14 (AS-509) mission - manned by astronauts Alan B. Shepard, Jr., Stuart A. Roosa, and Edgar D. Mitchell - was launched from Pad A, Launch Complex 39, KSC, at 4:03 p.m. EST January 31 on a Saturn V launch vehicle. A 40-minute hold had been ordered 8 minutes before scheduled launch time because of unsatisfactory weather conditions, the first such delay in the Apollo program. Activities during earth orbit and translunar injection were similar to those of the previous lunar landing missions. However, during transposition and docking, CSM 110 Kitty Hawk had difficulty docking with LM-8 Antares. A hard dock was achieved on the sixth attempt at 9:00 p.m. EST, 1 hour 54 minutes later than planned. Other aspects of the translunar journey were normal and proceeded according to flight plan. A crew inspection of the probe and docking mechanism was televised during the coast toward the moon. The crew and ground personnel were unable to determine why the CSM and LM had failed to dock properly, but there was no indication that the systems would not work when used later in the flight.

    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:

    • Third manned lunar landing mission and return.
    • Use of mobile equipment transporter (MET).
    • Payload of 32,500 kilograms placed in lunar orbit.
    • Distance of 3.3 kilometers traversed on lunar surface.
    • Payload of 43.5 kilograms returned from the lunar surface.
    • Lunar surface stay time of 33 hours.
    • Lunar surface EVA of 9 hours 47 minutes.
    • Use of shortened rendezvous technique.
    • Service propulsion system orbit insertion.
    • Active seismic experiment.
    • Inflight technical demonstrations.
    • Extensive orbital science period during CSM solo operations.

Related Persons: Cernan; Evans; Schmitt; Duke; Roosa; Young. Agency: NASA Houston. Program: Apollo. Class: Moon. Type: Manned lunar spacecraft. Flight: Apollo 17. Spacecraft: Apollo CSM. Duration: 12.58 days. Decay Date: 1972-12-19 . USAF Sat Cat: 6300 . COSPAR: 1972-096A. Apogee: 167 km (103 mi). Perigee: 167 km (103 mi). Inclination: 28.5260 deg. Period: 87.83 min. Apollo 17 (AS-512), the final Apollo manned lunar landing mission, was launched from Pad A, Launch Complex 39, KSC, at 12:33 a.m. EST December 7. Crew members were astronauts Eugene A. Cernan, Ronald E. Evans, and Harrison H. Schmitt. The launch had been delayed 2 hours 40 minutes by a countdown sequencer failure, the only such delay in the Apollo program caused by a hardware failure.

    All launch vehicle systems performed normally in achieving an earth parking orbit of 170 by 168 kilometers. After checkout, insertion into a lunar trajectory was begun at 3:46 a.m.; translunar coast time was shortened to compensate for the launch delay. CSM 114 transposition, docking with LM-12, and LM ejection from the launch vehicle stage were normal. The S-IVB stage was maneuvered for lunar impact, striking the surface about 13.5 kilometers from the preplanned point at 3:27 p.m. EST December 10. The impact was recorded by the passive seismometers left on the moon by Apollo 12, 14, 15, and 16.

    The crew performed a heat flow and convection demonstration and an Apollo light-flash experiment during the translunar coast. The scientific instrument module door on the SM was jettisoned at 10:17 a.m. EST December 10. The lunar orbit insertion maneuver was begun at 2:47 p.m. and the Apollo 17 spacecraft entered a lunar orbit of 315 by 97 kilometers. After separation of the LM Challenger from the CSM America and a readjustment of orbits, the LM began its powered descent and landed on the lunar surface in the Taurus-Littrow region at 2:55 p.m. EST on December 11, with Cernan and Schmitt.

    The first EVA began about 4 hours later (6:55 p.m.). Offloading of the lunar roving vehicle and equipment proceeded as scheduled. The Apollo Lunar Surface Experiment Package was deployed approximately 185 meters west northwest of the Challenger. Astronaut Cernan drove the lunar roving vehicle to the experiments deployment site, drilled the heat flow and deep core holes, and emplaced the neutron probe experiment. Two geological units were sampled, two explosive packages deployed, and seven traverse gravimeter measurements were taken. During the 7-hour 12-minute EVA, 14 kilograms of samples were collected.

    The second extravehicular activity began at 6:28 p.m. EST December 12. Because of geological interest, station stop times were modified. Orange soil was discovered and became the subject of considerable geological discussion. Five surface samples and a double core sample were taken in the area of the orange soil. Three explosive packages were deployed, seven traverse gravimeter measurements were taken, and observations were photographed. Samples collected totaled 34 kilograms during the 7 hours and 37 minutes of the second EVA.

    The third and final EVA began at 5:26 p.m. EST December 13. Specific sampling objectives were accomplished. Samples - including blue-gray breccias, fine-grained vesicular basalts, crushed anorthositic rocks, and soils - weighed 66 kilograms. Nine traverse gravimeter measurements were made. The surface electrical properties experiment was terminated. Before reentering the LM, the crew selected a breccia rock to dedicate to the nations represented by students visiting the Mission Control Center. A plaque on the landing gear of the lunar module, commemorating all of the Apollo lunar landings, was then unveiled. After 7 hours 15 minutes, the last Apollo EVA on the lunar surface ended. Total time of the three EVAs was approximately 22 hours; the lunar roving vehicle was driven 35 kilometers, and about 115 kilograms of lunar sample material was acquired.

    While Cernan and Schmitt were exploring the lunar surface, Evans was conducting numerous scientific activities in the CSM in lunar orbit. In addition to the panoramic camera, the mapping camera, and the laser altimeter, three new scientific instrument module experiments were included in the Apollo 17 orbital science equipment. An ultraviolet spectrometer measured lunar atmospheric density and composition; an infrared radiometer mapped the thermal characteristics of the moon; and a lunar sounder acquired data on the subsurface structure.

    Challenger lifted off the moon at 5:55 p.m. EST December 14. Rendezvous with the orbiting CSM and docking were normal. The two astronauts transferred to the CM with samples and equipment and the LM ascent stage was jettisoned at 1:31 a.m. December 15. Its impact on the lunar surface about 1.6 kilometers from the planned target was recorded by four Apollo 17 geophones and the Apollo 12, 14, 15, and 16 seismometers emplaced on the surface. The seismic experiment explosive packages that had been deployed on the moon were detonated as planned and recorded on the geophones.

    During the coast back to earth, Evans left the CSM at 3:27 p.m. EST December 17 for a 1-hour 7-minute inflight EVA and retrieved lunar sounder film and panoramic and mapping camera cassettes from the scientific instrument module bay. The crew conducted the Apollo light- flash experiment and operated the infrared radiometer and ultraviolet spectrometer.

    Reentry, landing, and recovery were normal. The command module parachuted into the mid-Pacific at 2:25 p.m. EST December 19, 6.4 kilometers from the prime recovery ship, U.S.S. Ticonderoga. The crew was picked up by helicopter and was on board the U.S.S. Ticonderoga 52 minutes after the CM landed. All primary mission objectives had been achieved.

  • Apollo (ASTP) - . Call Sign: Apollo. Crew: Brand; Slayton; Stafford. Backup Crew: Bean; Evans; Lousma. Payload: Apollo CSM 111. Mass: 14,768 kg (32,557 lb). Nation: USA. Related Persons: Brand; Slayton; Stafford; Bean; Evans; Lousma. Agency: NASA Houston. Program: ASTP. Class: Moon. Type: Manned lunar spacecraft. Flight: Soyuz 19 (ASTP); Apollo (ASTP). Spacecraft: Apollo CSM. Duration: 9.06 days. Decay Date: 1975-07-24 . USAF Sat Cat: 8032 . COSPAR: 1975-066A. Apogee: 166 km (103 mi). Perigee: 152 km (94 mi). Inclination: 51.7000 deg. Period: 87.60 min. 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.
