In 1969, the Soviet Union's space program had success with the docking of two manned spacecraft as well as the success of their Venus and Lunar probes. The Soviets, however, suffered severe blows to their manned Lunar aspirations when their N1 rocket failed twice during two 1969 launches. <br> 1969 in spaceflight 1969 saw humanity step onto another world for the first time. On 21 July 1969, the Apollo 11 Lunar Module,
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
