SpaceX Breakthrough as Mars 'Starship' Prototype Rocket Aces Successful Test Flight - ScienceAlert

SpaceX on Tuesday successfully completed a flight of less than a minute of the largest prototype ever tested of the future rocket Starship, which the company hopes to use one day to colonize Mars.

"Mars is looking real," SpaceX founder Elon Musk tweeted in response to a fan.

The current Starship prototype is fairly crude: it's a large metallic cylinder, built in a few weeks by SpaceX teams on the Texas coast, in Boca Chica – but it's still smaller than the actual rocket will be.
