23 March 1912: Wernher Magnus Maximilian Freiherr von Braun, rocket engineer, was born at Wyrzysk, Province of Posen, in the German Empire, in what is now Poland. He was the second of three children of Magnus Alexander Maximillian von Braun, head of the Posen provincial government, and Emmy von Quistorp.

Wernher von Braun originally wanted to be a musician and composer, having learned to play the cello and piano at an early age. After reading a speculative book on space flight, though, his interests shifted.

In 1929, the 17-year-old von Braun joined Verein für Raumshiffahrt, the German rocketry association. He worked with Hermann Oberth in testing liquid-fueled rockets, based on successful rockets designed by Dr. Robert H. Goddard in the United States.

Von Braun graduated from Technische Hochschule Berlin in 1932, with a degree in mechanical engineering (Diplom-Ingenieur). Two years later, he received a doctorate in physics (Dr. phil.) at Friederich-Wilhelm University of Berlin. He also studied at ETH Zürich.

In Germany before World War II, Dr.-Ing. von Braun worked on the problems of liquid-fueled rockets and developed the Aggregat series of rockets, including the A4, which would become known as the V-2 (Vegeltungswaffe 2) military rocket. The German Army’s Ordnance Department gave von Braun a grant to further study liquid-fueled rockets, which he pursued at an artillery range at Kummersdorf, just south of Berlin. As rocketry work expanded, the tests were eventually moved to the Peenemünde Military Test Site on the island of Usedom on the Baltic coast, where von Braun was technical director under Colonel Dr. Ing. Walter R. Dornberger.

The first successful launch of the A4 took place 3 October 1942. By the end of World War II, Nazi Germany had launched more than 3,200 V-2 rockets against Belgium, England, France and The Netherlands.

As World War II in Europe came to a close and the collapse of Nazi Germany was imminent, von Braun had to choose between being captured by the Soviet Red Army or by the Allies. He surrendered to the 324th Infantry Regiment, 44th Infantry Division, United States Army in the Bavarian Alps, 2 May 1945.

Under Operation Paperclip, Wernher von Braun and many other scientists, engineers and technicians were brought to the United States to work with the U.S. Army’s ballistic missile program at Fort Bliss, Texas, White Sands Proving Grounds, New Mexico, and the Redstone Arsenal, Huntsville, Alabama.

Sufficient parts and materiel and been transferred from Germany to construct more than one hundred V-2 rockets for testing at White Sands. Over a five year period, there were 67 successful launches, but it is considered that as much knowledge was gained from failures as successes.

In 1950, von Braun and his team were sent to Redstone Arsenal, Huntsville, Alabama, where they worked on more advanced rockets. The first production rocket was the short-range ballistic missile, the SSM-A-14 Redstone, which was later designated PGM-11. This rocket was capable of carrying a 3.8 megaton W39 warhead approximately 200 miles (322 kilometers) The first Redstone was launched at Cape Canaveral Air Force Station, 20 August 1953. Modified Redstone MRLV rockets were used to launch the first Mercury spacecraft with NASA astronauts Alan Shepherd and Gus Grissom. Von Braun later worked on the U.S. Army’s Jupiter-A intermediate range ballistic missile. A modified Jupiter-C was used to launch Explorer 1, the United States’ first satellite.

Wernher von Braun travelled to Germany in 1947 to marry his cousin, Maria Luise von Quistorp, and then returned to the United States. He became a naturalized citizen of the United States of America in 1955.

In 1960 von Braun and hist team were transferred from the Army Ballistic Missile Agency to NASA’s new Marshall Space Flight Center at Redstone Arsenal. He was now able to pursue his original interest, manned flight into space. Work proceeded on the Saturn rocket series, which were intended to lift heavy payloads into Earth orbit. This resulted in the Saturn A, Saturn B and the Saturn C series, ultimately becoming the Saturn V moon rocket.

With the Apollo Program coming to an end, Dr. von Braun left NASA in 1972. A year later, he was diagnosed with kidney cancer. Wernher von Braun died of pancreatic cancer, 17 June 1977 at the age of 65 years.

3 March 1969: At 11:00:00 a.m. Eastern Standard Time (16:00:00 UTC), Apollo 9 Saturn V (AS-504), the second manned Saturn V rocket, is launched from Launch Complex 39A at the Kennedy Space Center, Cape Canaveral, Florida. Aboard are astronauts Colonel James Alton McDivitt, U.S. Air Force, the Spacecraft Commander; Colonel David Randolph Scott, U.S. Air Force, Command Module Pilot; and Mr. Russell Louis Schweickart (formerly an Air Force pilot), Lunar Module Pilot. McDivitt and Scott were on their second space flight. Rusty Schweickert was on his first.

The 10-day Earth orbital mission is used to test docking-undocking with the lunar module, and to certify the LM as flight-worthy. This was necessary before the program could proceed to the next phase: The Moon.

The Apollo Command/Service Module was built by the Space and Information Systems Division of North American Aviation, Inc., at Downey, California.

The SPS engine was an AJ10-137, built by Aerojet General Corporation of Azusa, California. It burned a hypergolic fuel combination of Aerozine 50 and nitrogen tetraoxide, producing 20,500 pounds of thrust (91.19 kilonewtons). It was designed for a 750 second burn, or 50 restarts during a flight.

The Apollo Lunar Module was built by Grumman Aerospace Corporation to carry two astronauts from lunar orbit to the surface, and return. There was a descent stage and ascent stage. The LM was intended only for operation in the vacuum of space, and was expended after use.

The LM was 23 feet, 1 inches (7.036 meters) high with a maximum landing gear spread of 31 feet (9.449 meters). It weighed 33,500 pounds (15,195 kilograms). The spacecraft was designed to support the crew for 48 hours, though in later missions, this was extended to 75 hours.

The Descent Stage was powered by a single TRW LM Descent Engine. The LMDE used hypergoloc fuel and was throttleable. It produced from 1,050 pounds of thrust (4.67 kilonewtons) to 10,125 pounds (45.04 kilonewtons). The Ascent Stage was powered by a Bell Aerospace Lunar Module Ascent Engine. This also used hypergolic fuels. It produced 3,500 pounds of thrust (15.57 kilonewtons).

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 (6770.19 kilonewtons), each, for a total of 7,610,000 pounds of thrust at Sea Level (33,850.97 kilonewtons). 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 (1,022.01 kilonewtons), and combined, 1,161,250 pounds of thrust (717.28 kilonewtons).

The Saturn V third stage was designated S-IVB. It was built by Douglas Aircraft 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 would 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.

21 December 1968: At 12:51:00 UTC, Apollo 8 lifted off from Launch Complex 39A at the Kennedy Space Center, Cape Canaveral, Florida.  Aboard were Mission Commander Frank F. Borman II, Command Module Pilot James A. Lovell, Jr., and Lunar Module Pilot William A. Anders.

Apollo 8 was the second manned mission of the Apollo program. It was the first manned spacecraft to leave Earth orbit, travel to and orbit the Moon, then return to Earth.

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 Mission Commander, on his third space flight, was Eugene A. Cernan. The Command Module Pilot was Ronald A. Evans, on his first space flight, and the Lunar Module Pilot was Harrison H. Schmitt, also on his first space flight.

Schmitt was placed in the crew because he was a professional geologist. (He replaced Joe Engle, an experienced test pilot who had made sixteen flights in the X-15 hypersonic research rocketplane. Three of those flights were higher than the 50-mile altitude, qualifying Engle for U.S. Air Force astronaut wings.)

The launch of Apollo 17 was delayed for 2 hours, 40 minutes due to a minor mechanical malfunction. When it did liftoff, at 12:33 a.m. EST, the launch was witnessed by more than 500,000 people.
