22 May 1969, 21:30:43 UTC: Just over 100 hours after launch from Kennedy Space Center, Snoopy, the Lunar Module for the Apollo 10 mission came within 47,400 feet (14,447.5 meters) of the Lunar surface during a full dress rehearsal for the upcoming Apollo 11 landing. Mission Commander Thomas P. Stafford and Lunar Module Pilot Eugene A. Cernan rode Snoopy toward the surface and back, while John W. Young remained in orbit around the Moon aboard the Command and Service Module, Charlie Brown.

Thomas P. Stafford had flown two previous missions in the Gemini Program, Gemini 6 and Gemini 9. Apollo 10 was his third space flight.

John Watts Young flew six space missions: Gemini 3 and Gemini 10, Apollo 10 and Apollo 16, and Space Shuttle missions STS-1 and STS-9. He was to command STS-61J when the space shuttle fleet was grounded following the loss of Challenger. Young has flown 34 days, 19 hours, 39 seconds in space. He made 3 EVAs with a total of 20 hours, 14 minutes, 14 seconds outside his spacecraft.

Eugene A. Cernan had flown Gemini 9 with Stafford. He would later fly Apollo 17 back to the Moon. On 13 December 1972, Gene Cernan was the last man to stand on the surface of the Moon.

During the Apollo 10 mission, everything except an actual landing was done. The Lunar Module separated from the Command Service Module in lunar orbit and descended to within 47,400 feet (14,447.5 meters) of the surface. The CSM and LM were in lunar orbit for 2 days, 13 hours, 37 minutes, 23 seconds before returning to Earth. During the return, the CSM reached a maximum speed of 24,791 miles per hour (39,897 kilometers per hour).

At T+192:03:23 (16:52:25 UTC, 26 May) the Apollo capsule and the three astronauts splashed down in the Pacific Ocean 400 miles (643.7 kilometers) east of American Samoa. The duration of the mission was 8 days, 3 minutes, 23 seconds.

Eugene Andrew Cernan (The Provi of 1952)

Eugene Andrew Cernan was born at Chicago, Illinois, 14 March 1934. He was the second child of Andrew George Cernan, a manufacturing foreman, and Rose A. Cihlar Cernan. Gene Cernan graduated from Proviso East High School, Maywood, Illinois, in 1952.

Cernan entered Purdue University, West Lafayette, Indiana, as an engineering student. He was a midshipman in the U.S. Navy Reserve Officers Training Corps (R.O.T.C.), and a member of the Phi Gamma Delta fraternity (ΦΓΔ) , serving as treasurer. He was also president of the Quarterdeck Society and the Scabbard and Blade, and a member of the Phi Eta Sigma (ΦΗΣ) honor society and Tau Beta Pi (ΤΒΠ) engineering honor society. He served on the military ball committee and was a member of the Skull and Crescent leadership honor society. During his Midshipman Cruise in 1955, Cernan served aboard the Worcester-class light cruiser USS Roanoke (CL-145). Cernan graduated from Purdue in 1956 with Bachelor of Science Degree in Electrical Engineering (B.S.E.E.).

Cernan was commissioned as an ensign, United States Navy, 2 June 1956, and was assigned to flight training. He was promoted to lieutenant (junior grade), 1 December 1957. Lieutenant Cernan completed flight school and qualified as Naval Aviator. He was assigned to Attack Squadron 126 (VA-126) at NAS Miramar, San Diego, California, flying the North American Aviation FJ-4B Fury. On 1 June 1960, Cernan was promoted to the rank of lieutenant.

Cernan earned a Master of Science Degree in Aeronautical Engineering from the U.S. Naval Postgraduate School at Monterey, California, in 1963.

In October 1963, Lieutenant Cernan was selected as an Astronaut for the National Aviation and Space Administration (NASA). He was one of 14 members of NASA Astronaut Group 3, which was announced 18 October 1963.

Gene Cernan was promoted to the rank of commander, United States Navy, 3 June 1966. He flew as pilot of Gemini IX-A, 3-6 June 1966. (Thomas P. Stafford was the command pilot.) The mission included a rendezvous with a Lockheed Agena target vehicle. A planned docking with the Agena could not be carried out because the docking shroud had failed to deploy correctly. On 6 June, Cernan conducted an “EVA” (Extravehicular Activity, of “space walk”). During the 2 hour, 7 minute EVA, numerous difficulties were encountered.

Cernan was promoted to the rank of captain, United States Navy, 10 July 1970. He was next assigned as the backup to Alan B. Shepard as mission commander for Apollo 14.

On 23 January 1971, Cernan was flying a Bell Model 47G-3B-1 helicopter, NASA 947 (N947NA, serial number 6665), on a proficiency flight, when it crashed in the Indian River near Malabar, Florida. The helicopter was destroyed and Cernan was slightly injured. The official investigation reported the cause as a “misjudgement in estimating altitude.” In his autobiography, Cernan wrote,

Without ripples, the water provided no depth perception and my eyes looked straight through the clear surface to the reflective river bottom. I had lost sight of the water.

EDUCATION: Graduated from Orlando High School, Orlando, Florida; received a bachelor of science degree in aeronautical engineering with highest honors from Georgia Institute of Technology in 1952.

ORGANIZATIONS: Fellow of the American Astronautical Society (AAS), the Society of Experimental Test Pilots (SETP), and the American Institute of Aeronautics and Astronautics (AIAA).

SPECIAL HONORS: Awarded the Congressional Space Medal of Honor (1981), 4 NASA Distinguished Service Medals, NASA Outstanding Leadership Medal (1992), NASA Exceptional Engineering Achievement Medal (1987), NASA Outstanding Achievement Medal (1994), Navy Astronaut Wings (1965), 2 Navy Distinguished Service Medals, 3 Navy Distinguished Flying Crosses, the Georgia Tech Distinguished Young Alumni Award (1965), Distinguished Service Alumni Award (1972), the Exceptional Engineering Achievement Award (1985), the Academy of Distinguished Engineering Alumni (1994), and the American Astronautical Society Space Flight Award (1993), Distinguished Executive Award (1998), Rotary National Space Achievement Award (2000). Inducted into 6 Aviation and Astronaut Halls of Fame. Recipient of more than 80 other major awards, including 6 honorary doctorate degrees.

NAVY EXPERIENCE: Upon graduation from Georgia Tech, Young entered the United States Navy. After serving on the west coast destroyer USS LAWS (DD-558) in the Korean War, he was sent to flight training. He was then assigned to Fighter Squadron 103 for 4 years, flying Cougars and Crusaders.

After test pilot training at the U.S. Navy Test Pilot School in 1959, he was assigned to the Naval Air Test Center for 3 years. His test projects included evaluations of the Crusader and Phantom fighter weapons systems. In 1962, he set world time-to-climb records to 3,000-meter and 25,000-meter altitudes in the Phantom. Prior to reporting to NASA, he was maintenance officer of Phantom Fighter Squadron 143. Young retired from the Navy as a Captain in September 1976, after completing 25 years of active military service.

NASA EXPERIENCE: In September 1962, Young was selected as an astronaut. He is the first person to fly in space six times from earth, and seven times counting his lunar liftoff. The first flight was with Gus Grissom in Gemini 3, the first manned Gemini mission, on March 23, 1965. This was a complete end-to-end test of the Gemini spacecraft, during which Gus accomplished the first manual change of orbit altitude and plane and the first lifting reentry, and Young operated the first computer on a manned spacecraft. On Gemini 10, July 18-21, 1966, Young, as Commander, and Mike Collins, as Pilot, completed a dual rendezvous with two separate Agena target vehicles. While Young flew close formation on the second Agena, Mike Collins did an extravehicular transfer to retrieve a micro meteorite detector from that Agena. On his third flight, May 18-26, 1969, Young was Command Module Pilot of Apollo 10. Tom Stafford and Gene Cernan were also on this mission which orbited the Moon, completed a lunar rendezvous, and tracked proposed lunar landing sites. His fourth space flight, Apollo 16, April 16-27, 1972, was a lunar exploration mission, with Young as Spacecraft Commander, and Ken Mattingly and Charlie Duke. Young and Duke set up scientific equipment and explored the lunar highlands at Descartes. They collected 200 pounds of rocks and drove over 16 miles in the lunar rover on three separate geology traverses.

Young’s fifth flight was as Spacecraft Commander of STS-1, the first flight of the Space Shuttle, April 12-14, 1981, with Bob Crippen as Pilot. The 54-1/2 hour, 36-orbit mission verified Space Shuttle systems performance during launch, on orbit, and entry. Tests of the Orbiter Columbia included evaluation of mechanical systems including the payload bay doors, the attitude and maneuvering rocket thrusters, guidance and navigation systems, and Orbiter/crew compatibility. One hundred and thirty three of the mission’s flight test objectives were accomplished. The Orbiter Columbia was the first manned spaceship tested during ascent, on orbit, and entry without benefit of previous unmanned missions. Columbia was also the first winged reentry vehicle to return from space to a runway landing. It weighed about 98 tons as Young landed it on the dry lakebed at Edwards Air Force Base, California.

Young’s sixth flight was as Spacecraft Commander of STS-9, the first Spacelab mission, November 28-December 8, 1983, with Pilot Brewster Shaw, Mission Specialists Bob Parker and Owen Garriott, and Payload Specialists Byron Lichtenberg of the USA and Ulf Merbold of West Germany. The mission successfully completed all 94 of its flight test objectives. For ten days the 6-man crew worked 12-hour shifts around-the-clock, performing more than 70 experiments in the fields of atmospheric physics, Earth observations, space plasma physics, astronomy and solar physics, materials processing and life sciences. The mission returned more scientific and technical data than all the previous Apollo and Skylab missions put together. The Spacelab was brought back for re-use, so that Columbia weighed over 110 tons as Young landed the spaceship at Edwards Air Force Base, California.

Young was also on five backup space flight crews: backup pilot in Gemini 6, backup command module pilot for the second Apollo mission (before the Apollo Program fire) and Apollo 7, and backup spacecraft commander for Apollo 13 and 17. In preparation for prime and backup crew positions on eleven space flights, Young has put more than 15,000 hours into training so far, mostly in simulators and simulations.

He has logged more than 15,275 hours flying time in props, jets, helicopters, rocket jets, more than 9,200 hours in T-38s, and six space flights of 835 hours.

In January 1973, Young was made Chief of the Space Shuttle Branch of the Astronaut Office, providing operational and engineering astronaut support for the design and development of the Space Shuttle. In January 1974, he was selected to be Chief of the Astronaut Office, with responsibility for the coordination, scheduling, and control of activities of the astronauts. Young served as Chief of the Astronaut Office until May 1987. During his tenure, astronaut flight crews participated in the Apollo-Soyuz joint American-Russian docking mission, the Space Shuttle Orbiter Approach and Landing Test Program, and 25 Space Shuttle missions. From May 1987 to February 1996, Young served as Special Assistant to the Director of JSC for Engineering, Operations, and Safety. In that position, he had direct access to the Center Director and other senior managers in defining and resolving issues affecting the continued safe operation of the Space Shuttle. Additionally, he assisted the Center Director in providing advice and counsel on engineering, operational, and safety matters related to the Space Station, Shuttle upgrades, and advanced human Space Exploration Programs, back to the Moon and on to Mars.

In February 1996 Young was assigned as Associate Director (Technical), responsible for technical, operational and safety oversight of all Agency Programs and activities assigned to the Johnson Space Center. On December 31, 2004 Young retired from NASA. He continues to advocate the development of the technologies that will allow us to live and work on the Moon and Mars. Those technologies over the long (or short) haul will save civilization on Earth. the official biography of John W. Young from the National Aeronautics and Space Administration, Lyndon B.
