Landing a spacecraft on the moon has long been a series of hits and misses. Last year, a spacecraft built by Intuitive Machines through a NASA-sponsored program put the US back on the moon for the first time since the end of the Apollo program, but the lander ended up tipping on its side and operated briefly on the surface. Now another US company Firefly Aerospace on Sunday added its lunar lander to the win list, becoming the first private entity to pull off a fully successful moon landing. Both US businesses are part of NASA's effort to support commercial deliveries to the moon ahead of astronaut missions later this decade.

The U.S. follows four months later with Surveyor 1. Both countries achieve more robotic landings
