Japan's SLIM Probe Regains Power, Resumes Lunar Operations

The spacecraft, which landed more than a week ago, overcame a power outage due to solar panel displacement and has resumed its mission to analyze lunar rocks.

  • Japan's SLIM spacecraft has regained power more than a week after it achieved a precise lunar landing but ran out of electricity because its solar panels were at the wrong angle.
  • The probe was likely able to generate power thanks to a change in the sunlight's direction, and has resumed its operations to analyse the composition of olivine rocks on the lunar surface.
  • SLIM lost the thrust of one of its two main engines shortly before the touchdown for unknown reasons and ended up drifting a few dozen metres away from the target.
  • The probe's solar panels faced westward due to the displacement and could not immediately generate power. JAXA manually unplugged SLIM's dying battery 2 hours and 37 minutes after the touchdown.
  • JAXA does not have a clear date when SLIM will end its operation on the moon, but the agency has previously said the lander was not designed to survive a lunar night. The next lunar night begins on Thursday.
