Japan makes history with tense, successful moon landing Japan's SLIM “Moon Sniper” spacecraft made a successful lunar landing Friday, making the country just the fifth to robotically land on the moon.

Japan’s SLIM “Moon Sniper” spacecraft made a successful lunar landing Friday, making the country just the fifth to robotically land on the moon.

The Smart Lander for Investigating Moon (SLIM) spacecraft began its descent from a 15-kilometer perilune shortly after 10:00 a.m. Eastern, Jan. 19 (1500 UTC), decelerating from a speed of around 1,700 meters per second.

SLIM appeared to have successfully touched down at 10:20 a.m. (1520 UTC), during a Japan Aerospace Exploration Agency (JAXA) livestream of the event. It was not however immediately clear if the landing was successful, with the livestream ending inconclusively. A wait of more than an hour followed for clarification and confirmation.

JAXA confirmed landing success during a press conference just under two hours after the landing occurred. However the spacecraft’s solar cells were not generating electricity. The reason for the solar cell issue was not immediately known, but spacecraft orientation—suggesting the lander may have rolled—is consider a possibility. SLIM is currently working on battery power.

    Congrats to everyone at JAXA for touching down on the surface of the moon! It is a bummer it didn’t go entirely as planned but still a huge accomplishment and I’m sure they will get lots of valuable data for subsequent missions.
