On February 21, the first mission of the Moonrush embarked aboard a Falcon 9 rocket. The Beresheet lunar lander built by Israel’s SpaceIL was launched as a secondary payload, sharing the ride with the Indonesian communications satellite PSN-6. After reaching geostationary transfer orbit, Beresheet and the communications satellite separated from the Falcon 9 launcher. The communications satellite will propel itself to geostationary Earth orbit. Meanwhile, Beresheet is slowly raising its orbit. In early April the spacecraft will enter lunar orbit, then land on the Moon.
