Luna 2 also crash land on the Moon in exactly the same way. Crash landing proved useful even after soft landing was mastered.

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
