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 1 first instance of radio communication at the half-million-kilometer distance. A malfunction in the ground-based control system caused an error in the rocket's burntime, and the spacecraft missed the target and flew by the Moon at a distance of 5,900 km at the closest point. "Luna 1" then became the first man-made object to reach heliocentric orbit and was then dubbed a "new planet" and renamed "Mechta" ("Dream"). "Luna 1" was also referred to as the "First Cosmic Rocket", in reference to its achievement of escape velocity. "Luna 1" contained radio equipment including a tracking transmitter and telemetry system, and five
