A Japanese robotic spacecraft successfully set down on the moon on Friday — but its solar panels were not generating power, which will cut the length of time it will be able to operate to a few hours.

With this achievement, Japan is now the fifth country to send a spacecraft that made a soft landing on the moon.

For JAXA, Japan’s space agency which currently operates a variety of robotic science missions in space, this was the first time it had tried to set down on a planetary body elsewhere in the solar system. The spacecraft, the Smart Lander for Investigating Moon, or SLIM, was intended to demonstrate precision landing, within a football field of a targeted destination rather than an uncertainty of miles that most landers are capable of.

The technology could also be useful for future missions like those in NASA’s Artemis program . Japan is a partner in that program, which will send astronauts back to the moon in the coming years.
