History of spaceflight out by NASA. The programs goal was to orbit and land manned vehicles on the moon. The program ran from 1969 to 1972. Apollo 8 was the first manned spaceflight to leave earth orbit and orbit the Earth's moon on December 21, 1968. Neil Armstrong and Buzz Aldrin became the first men to set foot on the moon during the Apollo 11 mission on July 20, 1969. The Skylab programs goal was to create the first space station of NASA. The program marked the last launch of the Saturn V rocket on May 19, 1973. Many experiments were performed on
Spaceflight Shuttle fleet operated from April 1981 until July 2011. SpaceShipOne has conducted two human suborbital spaceflights. On a sub-orbital spaceflight the spacecraft reaches space and then returns to the atmosphere after following a (primarily) ballistic trajectory. This is usually because of insufficient specific orbital energy, in which case a suborbital flight will last only a few minutes, but it is also possible for an object with enough energy for an orbit to have a trajectory that intersects the Earth's atmosphere, sometimes after many hours. Pioneer 1 was NASA's first space probe intended to reach the Moon. A partial failure caused
