SLIM, Japan’s historic moon lander, is officially powered down in preparation for a brutal, likely fatal lunar nighttime lasting around 14.5 days. Before drifting off to what very probably will be a permanent slumber, however, the small craft beamed back a few final glimpses of its new home to mission control at the Japanese space agency, JAXA.

“Last night (January 31st to February 1st), we sent a command to turn on the probe’s communication device just in case, and when there was no response, we confirmed that SLIM had entered a dormant state,” reads a machine translated message from JAXA posted to X on Thursday. “This is the last scene taken by SLIM with its navigation camera before dusk.”
After completing operation from 1/30 ~ 1/31, #SLIM entered a two week dormancy period during the long lunar night 🌚. Although SLIM was not designed for the harsh lunar nights, we plan to try to operate again from mid-February, when the Sun will shine again on SLIM’s solar cells. pic.twitter.com/JO4ZgDaOxo

Japan’s Smart Lander for Investigating Moon, or SLIM, first ran into trouble during its descent on January 19, when its main engines malfunctioned approximately 162-feet above the lunar surface. The resultant loss of thrust threw the lander off kilter, and while it arrived intact, it did so nosedown with SLIM’s solar panels faced westward. Engineers worried the lander would be unable to generate enough power to continue communicating with Earth for very long, and SLIM subsequently went silent only a few hours after its arrival—although its two, tiny autonomous robots ejected unscathed to begin their own surveys.
