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.

20 August 1977: Voyager 2 was launched from Launch Complex 41 at the Kennedy Space Center, Cape Canaveral, Florida, aboard a Titan IIIE-Centaur launch vehicle. It was placed on an orbital trajectory that would take it on a journey throughout the Solar System and beyond.

Nearly two years later, 9 July 1979, Voyager 2 made its closest approach to Jupiter, passing within 350,000 miles (570,000 kilometers) of the planet. Many dramatic images as well as scientific data were transmitted back to Earth.

The probe continued outward to Saturn, Neptune and Uranus, continuously transmitting images and data. In 1990, the space probe passed beyond the limits of the Solar System.

Voyager 2 is now in interstellar space. It crossed the heliopause, where “solar wind” is slowed by the pressure of interstellar gas, 5 November 2018. It is still operating, 46 years after it was launched.

On 21 July 2023, an erroneous instruction caused Voyager 2 to turn its antenna away from Earth, but on 5 August 2023, contact was reestablished. A power reduction strategy is hoped to allow the space probe to continue operating until 2026.

As of 15 August 2024, Voyager 2 was 136 Astronomical Units from Earth (20,345,310,413 kilometers/12,641,989,788 statute miles/10,985,588,776 nautical miles). Radio signals, traveling at the Speed of Light, take 18 hours, 56 minutes to cross that distance. It continues outbound at a rate of 3.3 AU/year. (With respect to the Sun, Voyager 2 is traveling outbound at 15.35 kilometers per second (33,330.48 miles per hour/29,832.37 knots).

20 August 1975: The Viking 1 space probe was launched from Kennedy Space Center, Cape Canaveral, Florida, aboard a Titan IIIE/Centaur rocket. For the next ten months it traveled to Mars, the fourth planet of the Solar System. Once there, it was placed in orbit and began sending telemetry data back to Earth. A Viking Lander descended to the planet’s surface, landing at Chryse Planitia.

This was the first time that a spacecraft had landed on another planet. The orbiter continued to operate over the course of 1,485 orbits. As it ran low on fuel, mission controllers boosted it into a higher orbit to prevent it falling to the planet. Orbiter operations were terminated 17 August 1980. The lander operated for 6 years, 116 days, before the mission was terminated by a faulty transmission which resulted in a loss of contact, 11 November 1982.

17 August 1958: In what was the first attempt to launch a spacecraft beyond Earth orbit, Thor-Able 1 (Missile Number 127) was to place a small instrumented satellite in orbit around the Moon. Called Pioneer,¹ the satellite carried a television camera, a micrometeorite detector and a magnetometer.

The mission was carried out by the U.S. Air Force Ballistic Missile Division and the Advanced Research Projects Agency (ARPA).

The Thor-Able lifted off from Launch Complex 17A at the Cape Canaveral Air Force Station, Florida, at 12:28:00 UTC, 4 minutes behind schedule.

73.6 seconds into the flight, at an altitude of 9.9 miles (16 kilometers), the first stage of the rocket exploded. Telemetry from the upper stages continued and was tracked until impact in the Atlantic Ocean.

An investigation found the cause of the explosion to be a turbopump failure. It was determined that a bearing in the pump’s gearbox seized, halting the flow of liquid oxygen.

The Thor Able was a two-stage orbital launch vehicle which was developed from the Douglas Aircraft Company’s SM-75 Thor intermediate-range ballistic missile.

Designated Thor DM-19, the first stage was 60.43 feet (18.42 meters) long and 8 feet (2.44 meters) in diameter. Fully fueled, the first stage had a gross weight of 108,770 pounds (49,337 kilograms). It was powered by a Rocketdyne LR-79-7 engine which burned liquid oxygen and RP-1 (a highly-refined kerosene rocket fuel) and produced 170,565 pounds of thrust (758.711 kilonewtons). This stage had a burn time of 2 minutes, 45 seconds.

The second stage was an Aerojet General Corporation-built Able, a second stage for the U.S. Navy’s Vanguard rocket. It was 21 feet, 6.6 inches (6.57 meters) long with a maximum diameter of 2 feet, 9 inches (0.84 meters), and had a gross weight of 5,000 pounds (2,268 kilograms). It used an Aerojet AJ10-101 rocket engine which burned a hypergolic mixture of nitric acid and UDMH. The second stage produced 7,711 pounds of thrust (34.300 kilonewtons) and burned for 1 minutes, 55 seconds.

The Altair X248 third stage was developed by the Alleghany Ballistics Laboratory for the U.S. Navy’s Vanguard rocket. It was 4 feet, 11 inches (1.499 meters) long, 2 feet, 7 inches (0.787 meters) in diameter, and weighed 505 pounds (229 kilograms). It was powered by a solid fuel rocket engine producing 2,300 pounds (10.231 kilonewtons) of thrust. Its burn time was 38 seconds.

The first Pioneer space probe is today designated Pioneer 0. It was built by the Ramo-Wooldridge Corporation’s Space Technologies Laboratory (STL) in Redondo Beach, California.

The lunar probe was the fourth stage  of the Thor-Able launch vehicle. It was 74 centimeters (2 feet, 5.13 inches) in diameter, 76 centimeters (2 feet, 5.9 inches) long, and weighed 38.1 kilograms (83.996 pounds). The probe’s external shell was constructed of metal and fiberglass. It carried 11.3 kilograms (24.9 pounds) of instruments designed to measure magnetic fields, radiation and micrometeorites. It also carried an infrared camera system intended to obtain close-up images of The Moon’s surface. Pioneer 0 was spin-stabilized, turning 108 r.p.m.

The probe was equipped with a Thiokol TX-8-6 solid rocket engine to decelerate it for entry into lunar orbit. The rocket engine was the main structural component of the probe. There were 8 vernier rockets to correct its trajectory.

20 May 1969: The Apollo 11 Saturn V (SA-506) “stack” was rolled out of the Vehicle Assembly Building aboard a Mobile Launch Platform, carried by a Crawler-Transporter, and moved to Launch Complex 39A. The rocket would be launched for the Moon at 13:32:00 UTC, 16 July 1969.

The two Crawler-Transporters are the world’s largest self-propelled land vehicles. They were designed and built by Marion Power Shovel Company, Marion, Ohio, and were assembled on Merritt Island. (The Crawlerway connected the island to mainland Florida, so that it now forms a peninsula.) They are 131 feet (39.9 meters) long and 113 feet  (34.4 meters) wide. The height is adjustable from 20 feet (6.1 meters) to 26 feet (7.9 meters). The load deck is 90 feet × 90 feet (27.4 × 27.4 meters). The transporters weigh 2,721 metric tons (3,000 tons).

The Crawler-Transporters were powered by two 10,687.7-cubic-inch-displacement (175.1 liters) liquid-cooled, turbosupercharged, American Locomotive Company (ALCO) V-16 251C 45° sixteen-cylinder 4-cycle diesel engines. This engine produced 2,750 horsepower. The engines drive four 1,000 kilowatt electric generators. These in turn supply electricity to sixteen 375 horsepower traction motors.

Two 1,065 horsepower White-Superior eight-cylinder diesel engines provide electrical and hydraulic power to operate the crawlers’ systems. The hydraulic system operates at 5,200 p.s.i.

The maximum loaded speed is 0.9 miles per hour (1.4 kilometers per hour).

Since the time of the Apollo and Space Shuttle Programs, the Crawler-Transporters have been upgraded to handle the Space Launch System (SLS) heavy-lift rockets. The original ALCO locomotive engines have been replaced by two Cummins QSK95 16-cylinder diesel/C3000-series 1,500 kW power generation units. The new engine displaces 5,797 cubic inches and produces a maximum 4,200 horsepower at 1,200 r.p.m. The QSK95 has 46% less displacement than the old ALCO, weighs 39% less, but produces 57% more horsepower. The generators also double the electrical output.

The Saturn V rocket was a three-stage, liquid-fueled heavy launch vehicle. Fully assembled with the Apollo Command and Service Module, it stood 363 feet (110.642 meters) tall. The first and second stages were 33 feet (10.058 meters) in diameter. Fully loaded and fueled the rocket weighed 6,200,000 pounds (2,948,350 kilograms). It could lift a payload of 260,000 pounds (117,934 kilograms) to Low Earth Orbit.

The first stage was designated S-IC. It was designed to lift the entire rocket to an altitude of 220,000 feet (67,056 meters) and accelerate to a speed of more than 5,100 miles per hour (8,280 kilometers per hour). The S-IC stage was built by Boeing at the Michoud Assembly Facility, New Orleans, Louisiana. It was 138 feet (42.062 meters) tall and had an empty weight of 290,000 pounds (131,542 kilograms). Fully fueled with 203,400 gallons (770,000 liters) of RP-1 and 318,065 gallons (1,204,000 liters) of liquid oxygen, the stage weighed 5,100,000 pounds (2,131,322 kilograms). It was propelled by five Rocketdyne F-1 engines, producing 1,522,000 pounds of thrust, each, for a total of 7,610,000 pounds of thrust at Sea Level. These engines were ignited seven seconds prior to lift off and the outer four burned for 168 seconds. The center engine was shut down after 142 seconds to reduce the rate of acceleration. The F-1 engines were built by the Rocketdyne Division of North American Aviation at Canoga Park, California.

The S-II second stage was built by North American Aviation at Seal Beach, California. It was 81 feet, 7 inches (24.87 meters) tall and had the same diameter as the first stage. The second stage weighed 80,000 pounds (36,000 kilograms) empty and 1,060,000 pounds loaded. The propellant for the S-II was liquid hydrogen and liquid oxygen. The stage was powered by five Rocketdyne J-2 engines, also built at Canoga Park. Each engine produced 232,250 pounds of thrust, and combined, 1,161,250 pounds of thrust.

The Saturn V third stage was designated S-IVB. It was built by McDonnell Douglas Astronautics Company at Huntington Beach, California. The S-IVB was 58 feet, 7 inches (17.86 meters) tall with a diameter of 21 feet, 8 inches (6.604 meters). It had a dry weight of 23,000 pounds (10,000 kilograms) and fully fueled weighed 262,000 pounds. The third stage had one J-2 engine and also used liquid hydrogen and liquid oxygen for propellant. The S-IVB wou place the Command and Service Module into Low Earth Orbit, then, when all was ready, the J-2 would be restarted for the Trans Lunar Injection.

Eighteen Saturn V rockets were built. They were the most powerful machines ever built by man.
