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
Konrad Dannenberg a rocket engine for the V-2 ballistic missile. He was at Peenemünde on 3 October 1942 to witness the launch of the first man-made object to reach outer space, a V-2 rocket. This was the first man-made vehicle to reach space based on a then-current definition of 50 miles in altitude (see Kármán line for relevant background). Many improvements on which he worked could not be completed in time for production. After Thiel's death in an August 1943 bombing raid, a design freeze stopped all development efforts. Dannenberg then became Walter Riedel's deputy and headed the crash effort to finalize
