CAPE CANAVERAL, Fla. (AP) — A private U.S. lunar lander has touched down on the moon, but company officials say it was sending a weak signal.

The lander guided itself to the surface Thursday, searching for a relatively flat spot among all the cliffs and craters near the south pole.

Intuitive Machines was striving to become the first private business to pull off a lunar landing, a feat achieved by only five countries.

The craft is part of NASA’s efforts to commercialize moon deliveries ahead of the planned return of astronauts.

There hasn’t been a U.S. spacecraft on the moon since the end of NASA’s Apollo program.
