As President Donald Trump and Elon Musk argued on social media on Thursday, the world's richest man threatened to decommission a space capsule used to take astronauts and supplies to the International Space Station.
A few hours later, Musk said he wouldn't follow through on the threat.
After Trump threatened to cut government contracts given to Musk's SpaceX rocket company and his Starlink internet satellite services, Musk responded via X that SpaceX "will begin decommissioning its Dragon spacecraft immediately.''
It was unclear how serious Musk's threat was, but several hours later — in a reply to another X user — he said he wouldn't do it.
The capsule, developed with the help of government contracts, is an important part of keeping the space station running. NASA also relies heavily on SpaceX for other programs including launching science missions and, later this decade, returning astronauts to the surface of the moon.
The Dragon capsule
SpaceX is the only U.S. company capable right now of transporting crews to and from the space station, using its four-person Dragon capsules.
Boeing's Starliner capsule has flown astronauts only once; last year's test flight went so badly that the two NASA astronauts had to hitch a ride back to Earth via SpaceX in March, more than nine months after launching last June.
