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 The original ALCO locomotive engines have been replaced by two Cummins QSK95 16-cylinder diesel/C3000-series 1,500 kW power generation units.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.

20 January 1930: Colonel Edwin E. Aldrin, Jr., Sc.D., United States Air Force (Retired), was born at Glen Ridge, New Jersey, the second child of Edwin Eugene Aldrin, Aviation Director of Standard Oil Company of New Jersey, and Marion Gaddys Moon Aldrin.
The family resided in Montclair, New Jersey. “Buzz” Aldrin attended Montclair High School, and participated in football and track and field (pole vault). He graduated in 1947.
After high school, Aldrin turned down a full scholarship to attend the Massachusetts Institute of Technology (M.I.T.) and instead entered the United States Military Academy at West Point, New York. During his Plebe Year (freshman), Cadet Aldrin placed first in academics and physical education. He was a member of the French Club and the track and swim teams. In his third year he was a cadet corporal, and was designated as “distinguished.” He served as a cadet lieutenant during his final year.

Aldrin graduated from West Point on 5 June 1951 with a Bachelor of Science Degree in Mechanical Engineering (B.S.M.E.). He was ranked third in his class. A notation in the class yearbook states,
“As is evidenced by his fine record at the Academy, Buzz should make a capable, dependable and efficient officer in the U.S. Air Force.”
—The Howitzer 1951, at Page 98
Aldrin accepted a commission as a second lieutenant in the United States Air Force, with his date of rank retroactive to 1 June 1951. Second Lieutenant Aldrin was assigned to basic flight training at Bartow Air Force Base, Florida. Advanced training took place at Bryan Air Force Base, Texas. He trained as a fighter pilot and transitioned to the North American Aviation F-86 Sabre at Nellis Air Force Base, near Las Vegas, Nevada.
Lieutenant Aldrin flew the North American Aviation F-86E Sabre with the 16th Fighter Interceptor Squadron, 51st Fighter Interceptor Wing, located at Suwon Air Base (K-13), Korea. On 14 May 1953 he shot down an enemy Mikoyan-Gurevich MiG 15 fighter, for which he was awarded the Distinguished Flying Cross.¹ Three weeks later, 7 June, he shot down a second MiG 15.

In 1959 Captain Aldrin returned to the United States to enter a masters degree program in aeronautics at the Massachusetts Institute of Technology, Cambridge, Massachusetts. Aldrin and his wife were both very seriously ill at this time, and he was a patient in a military hospital for the first six months. With nothing to do but study, Aldrin finished first among the other Air Force officers in the program.
Aldrin remained at M.I.T. to earn a Doctorate in Science in Astronautics (Sc.D.) by devising orbital navigation techniques. His thesis on Manned Orbital Rendezvous, earned Buzz another nickname: “Dr. Rendezvous.”
In October 1963, Major Aldrin was selected as an astronaut for the Gemini Program. He was one of 14 members of NASA Astronaut Group 3, which was announced 18 October 1963. He flew with James A. Lovell, Jr., aboard Gemini XII, 11–15 November 1966. They made 59 orbits of the Earth in 3 days, 22 hours, 34 minutes, 31 seconds. Aldrin performed the first successful “space walk.” He was outside the spacecraft for three “EVAs,” of 2 hours, 29 minutes; 2 hours, 6 minutes; and 55 minutes. A rendezvous and docking with an Agena target vehicle was also successful.

Neil A. Armstrong
Neil A. Armstrong, the first man to walk on the moon, was born in Wapakoneta, Ohio, on August 5, 1930. He began his NASA career in Ohio.
After serving as a naval aviator from 1949 to 1952, Armstrong joined the National Advisory Committee for Aeronautics (NACA) in 1955. His first assignment was with the NACA Lewis Research Center (now NASA Glenn) in Cleveland. Over the next 17 years, he was an engineer, test pilot, astronaut and administrator for NACA and its successor agency, the National Aeronautics and Space Administration (NASA).
As a research pilot at NASA’s Flight Research Center, Edwards, Calif., he was a project pilot on many pioneering high speed aircraft, including the well known, 4000-mph X-15. He has flown over 200 different models of aircraft, including jets, rockets, helicopters and gliders.
Armstrong transferred to astronaut status in 1962. He was assigned as command pilot for the Gemini 8 mission. Gemini 8 was launched on March 16, 1966, and Armstrong performed the first successful docking of two vehicles in space.
As spacecraft commander for Apollo 11, the first manned lunar landing mission, Armstrong gained the distinction of being the first man to land a craft on the moon and first to step on its surface.
Armstrong subsequently held the position of Deputy Associate Administrator for Aeronautics, NASA Headquarters, Washington, D.C. In this position, he was responsible for the coordination and management of overall NASA research and technology work related to aeronautics.
He was Professor of Aerospace Engineering at the University of Cincinnati between 1971-1979. During the years 1982-1992, Armstrong was chairman of Computing Technologies for Aviation, Inc., Charlottesville, Va.
He received a Bachelor of Science Degree in Aeronautical Engineering from Purdue University and a Master of Science in Aerospace Engineering from the University of Southern California. He holds honorary doctorates from a number of universities.
Armstrong is a Fellow of the Society of Experimental Test Pilots and the Royal Aeronautical Society; Honorary Fellow of the American Institute of Aeronautics and Astronautics, and the International Astronautics Federation.
He is a member of the National Academy of Engineering and the Academy of the Kingdom of Morocco. He served as a member of the National Commission on Space (1985-1986), as Vice-Chairman of the Presidential Commission on the Space Shuttle Challenger Accident (1986), and as Chairman of the Presidential Advisory Committee for the Peace Corps (1971-1973).
Armstrong has been decorated by 17 countries. He is the recipient of many special honors, including the Presidential Medal of Freedom; the Congressional Space Medal of Honor; the Explorers Club Medal; the Robert H.
