![]() ![]() Using a flight simulator, Ken Mattingly and the NASA engineers measured the number of amps that each of the reentry procedures required and found a way to steer the spacecraft through reentry with the limited amount of power left in the CSM’s batteries.Īpollo was a Greek God, the son of Zeus and Leto. The batteries in the CSM had been damaged in the explosion and were generating only a small portion of their usual power. No astronaut was at fault.Īn ampere (“amp” for short) is a unit used to measure the flow of electrical current, i.e., the number of electrons passing a certain point each second. The insulation on the wire burned, triggering the explosion. Later, it was found that the cause of the loss of the spacecraft was an explosion that occurred because of a defective wire connecting a fan used to stir liquid oxygen. After several harrowing experiences, including almost freezing to death and being nearly asphyxiated by carbon dioxide, enough power was found to use the CSM for reentry. The Lunar Module had no heat shield and therefore could not be used for re-entry into the earth’s atmosphere. To preserve power, the crew retreated to the Lunar Module and deactivated the systems in the CSM. The abort systems intended to permit an emergency return to earth were knocked out. ![]() Electrical power and other systems were damaged. As the space ship was preparing to begin lunar landing operations, an explosion occurred in the Command and Service Module (CSM). In 1972, most of its goals having been accomplished, the Apollo program was abandoned so that NASA could concentrate on the space shuttle.Īpollo 13, launched on April 11, 1970, was crewed by James A. No other country has landed a man on the moon. spent 25 billion dollars on the Apollo program. Three of the missions, Apollo 14, 16, and 17, were extended stays on the surface of the moon in which the astronauts used a two-man Lunar Roving Vehicle to cross the Moon’s surface.ĭuring the busiest years of the Apollo program, NASA had 36,000 permanent employees, 376,700 contract employees, and a yearly operating budget of $5.2 billion. ![]() The Apollo program landed six space ships on the moon beginning with Apollo 11 on July 16, 1969. His purpose was to provide a clear goal in the American effort to surpass the Soviet space program. In 1961 President Kennedy committed the United States to a program to put a man on the moon by 1970.
