SpaceX CEO Elon Musk said on Tuesday that the company's ambitious Starship launch vehicle's next flight test is now expected to be next week, later than his previous timeline of Jan. 10.

Starship is scheduled to launch from Starbase on Monday (Jan. 13) at 5:00 p.m. EST (2200 GMT). It will be the seventh test flight for the giant rocket, which SpaceX is developing to help humanity settle Mars and achieve a variety of other exploration feats.

SpaceX’s most ambitious Starship flight yet will see reused hardware, the deployment of 10 fake satellites and another attempt to catch the booster with “chopsticks”
