Watch: SpaceX test fires powerful giant Starship spacecraft

SpaceX is a big step closer to sending its giant Starship spacecraft into orbit, completing an engine-firing test at the launch pad on Thursday.

Thirty-one of the 33 first-stage booster engines ignited for about 10 seconds in south Texas. The team turned off one engine before sending the firing command and another engine shut down _ "but still enough engines to reach orbit!" tweeted SpaceX's Elon Musk.

Musk estimates Starship's first orbital test flight could occur as soon as March if testing goes well.

The booster remained anchored to the pad as planned during the test. There were no signs of major damage to the launch tower.

NASA is counting on Starship to land astronauts on the moon in a few years, while rich businessmen already are booking lunar flybys. Farther down the road, Musk wants to use the mammoth Starships to send crowds to Mars.
