Private spaceflight company SpaceX successfully landed a reusable rocket stage Monday for the first time.
The Falcon 9 rocket stage propelled a payload of satellites about 62 miles into space before the second stage took over. The first stage then landed safely on the ground directly on target.
Reusable rocket stages are a crucial step in making private space operations more cost effective, according to the company.
SpaceX has gotten close before, but until today they hadn't stuck the landing.
SpaceX competitor Blue Origin recently performed a similar landing successfully, but this landing was from a much lower altitude.
Musk was understandably elated:
