Benefits of space exploration earth and space have increased. The list of missions to the moon begin as early as 1958 and continued into the current age. A few successful lunar missions, by the USSR, include missions such as, the Luna 1 space craft that completed the first flyby of the moon in 1959, the Luna 3 lunar probe that took the first pictures of the far side of the moon in 1959, the Luna 10 orbiter that was the first orbiter of the moon in 1966, and the Lunokhod 1 lunar rover in 1970, which was the first rover that explored the surface
Surveyor program time that NASA tested such systems in the challenging thermal and radiation environment near the Moon. Each Surveyor mission consisted of a single unmanned spacecraft designed and built by Hughes Aircraft Company. The launch vehicle was the Atlas-Centaur, which injected the craft directly into trans-lunar flightpath. The craft did not orbit the Moon on reaching it, but directly decelerated from impact trajectory, from 2.6 km/s relative to the Moon before firing retrorockets to a soft landing about 3 minutes 10 seconds later. Each craft was planned to slow to about 110 m/s (4% of speed before retrofire) by a main
