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 2 a different vehicle, delaying the flight by three days. "Luna 2", like "Luna 1", took a direct path to the Moon, with a velocity high enough to result in a travel time of around 36 hours. "Luna 2" hit the Moon about from the centre of the visible disk on 1959 September 13 at 21:02:24 UTC. "Luna 2" was similar in design to "Luna 1", a spherical spacecraft with protruding antennas and instrumentation. The instrumentation was also similar to Luna 1, including scintillation counters, geiger counters, a magnetometer, Cherenkov detectors, and micrometeorite detectors. There were no propulsion systems on "Luna
