IAI Beresheet

IAI Beresheet was a demonstrator of a small robotic lunar lander and lunar probe, co-developed by SpaceIL and Israel Aerospace Industries with support from the Israel Space Agency and its major financier Morris Kahn. It was the first privately initiated Moon mission and was stimulated by the Google Lunar X Prize. The lander stood about 1.5 metres high, had a net mass of 150 kilograms and about 585 kilograms when fuelled at launch. Its propulsion system was designed and built by Israel Aerospace Industries and used monomethylhydrazine fuel with mixed oxides of nitrogen oxidizer, with a restartable main engine called the LEROS 2b. It launched on 22 February 2019 on a SpaceX Falcon 9 as a secondary payload, was captured into lunar orbit on 4 April 2019, and crashed on the Moon on 11 April 2019 after a gyroscope failure during the landing approach.
