Unmanned spacecraft "SLIM" enters "dormant state" at night JAXA. The Japanese unmanned probe SLIM successfully landed on the moon last month.
It has been using its onboard solar cells to generate electricity and proceed with the investigation. But the sun appeared at the landing site... and the spacecraft is not designed to withstand such low temperatures. It is known that temperatures on the lunar surface can drop to around -170 degrees Celsius at night. If the situation can be maintained, we would like to restart the investigation, the agency said.
