SpaceX just launched a satellite that could help pave the way for a private space station in the very near future.

A Falcon 9 rocket lifted off from Cape Canaveral Space Force Station in Florida today at 1:09 a.m. EDT (0509 GMT), on a multi-satellite rideshare mission that SpaceX calls Bandwagon-4.

Among the 18 payloads on board the Falcon 9 is Haven Demo, a pathfinder for Haven-1, the private space station that California company Vast Space plans to launch to Earth orbit next year.

"The first step in our iterative approach towards building next-generation space stations, Haven Demo will test critical systems for Haven-1, including propulsion, flight computers and navigation software," Vast wrote in a description of the satellite.

Vast's Haven-1 will launch to low Earth orbit (LEO) atop a Falcon 9, perhaps as soon as the second quarter of 2026. If that schedule holds, Haven-1 — which can support up to four astronauts at a time — will be the first standalone private space station in human history.

The other 17 payloads that went up today will be operated by South Korea's Agency for Defense Development (ADD), the Berlin-based company Exolaunch, Turkey's Fergani Space, the weather-forecasting outfit Tomorrow Companies and Starcloud, which aims to build data centers in space.
