Luna 2 also crash land on the Moon in exactly the same way. Crash landing proved useful even after soft landing was mastered. NASA used crash landings to test whether Moon craters contained ice by crashing space probes into craters and testing the debris that got thrown out. The satellite's impact made it the first man-made object to land on another celestial body. "Luna 2" carried 5 different instruments to conduct various tests while it was on its way to the Moon. The scintillation counters would be used to measure any ionizing radiation; the Cherenkov radiation detectors would be measuring for electromagnetic
Luna programme not assigned a Luna number. Those that failed in low Earth orbit were usually given Cosmos designations. The estimated cost of the Luna programme was about $4.5 billion. "Luna 1" (January 1959) missed its intended impact with the Moon and became the first spacecraft to fall into orbit around the Sun. "Luna 2" (September 1959) mission successfully hit the Moon's surface, becoming the first man-made object to reach the Moon. "Luna 3" (October 1959) rounded the Moon later that year, and returned the first photographs of its far side, which can never be seen from Earth. "Luna 9" (February 1966)
