SpaceX is preparing for the next test flight of its massive Starship prototype rocket, as debate swirls over founder Elon Musk's influence on the US government's space program. Starship is designed to eventually be fully reusable and is key to Musk's vision of colonizing Mars.

SpaceX announced a one-day delay from a targeted launch on Mar. 5 in a post on X Wednesday morning. You can watch the Flight 8 launch live here at Space.com, courtesy of SpaceX, or directly via the company. Coverage will begin about 40 minutes before liftoff.
