Starship just completed its last flight of 2025. What comes next for Musk’s SpaceX.

Following a successful test flight for Starship, SpaceX is done with launches for the year and will be working to ready the next generation of its technology — in pursuit of lofty ambitions like an eventual colonization of Mars.

The 404-foot reusable megarocket, which is made up of the Super Heavy booster and the Starship upper stage, ascended from SpaceX’s Starbase facility in South Texas at 7:23 p.m. ET Monday. Over the course of about an hour, the Super Heavy booster successfully separated from Starship and made a soft splashdown in the Gulf of Mexico. Starship launched a series of mock Starlink satellites, briefly relit one of its engines and performed some tests before splashing down in the Indian Ocean.
