It appears that the second engine burn to raise the orbit of Israel’s privately built lunar lander, Beresheet, did not happen as planned because of an unexpected computer reboot.
In a statement Tuesday morning, SpaceIL and Israel Aerospace Industries (IAI) engineers said they were investigating the malfunction, but said that other than a known problem with the navigation system’s star tracker, the Beresheet’s systems were all functioning properly.
The maneuver was scheduled to take place Monday night, as the spacecraft passed near the Earth in an area where the Ramat Gan-based SpaceIL ground crew would not be in direct communication with the craft.
During the pre-maneuver phase, the spacecraft computer reset unexpectedly, and the maneuver was automatically cancelled.
The question that immediately comes to mind: Did they purchase a space-hardened computer? Cosmic rays can wreck havoc on computer memory, causing just this type of unexpected reset, so computers in space need to be much better shielded than on Earth.
