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 (rocket) over the cause and solution to it. It was believed that the vibrations developed as a consequence of adding the Blok E upper stage to the R-7, shifting its center of mass. The first probe launched by a Luna 8K72 to reach orbit was Luna 1, launched 2 January 1959, which was intended as a lunar impactor mission. Luna 1 instead passed within of the Moon's surface 4 January 1959, and then went into orbit around the Sun between the orbits of Earth and Mars. The fifth flight of a Luna 8K72 (July 1959) ended 220 seconds after launch due
