Blue Ghost, a NASA-funded lunar lander built and operated by the private U.S. company Firefly Aerospace, has successfully touched down on the moon.

After 45 days in space—and a pulse-pounding semi-autonomous hour-long descent to its landing site—at 3:34 A.M. EST the boxy, car-sized spacecraft’s four footpad-tipped legs crunched into the surface of Mare Crisium, a vast and ancient impact basin filled with frozen lava on the moon’s northeastern near side. This marks the second time the U.S. has soft-landed on the moon since the crewed Apollo 17 mission of 1972
