The SpaceX test-burner engine on massive new Starship for the first time



SpaceX's massive new spacecraft tests its rocket engine for the first time Wednesday.

The "jumps" version of the Starship rocket – doubled Starhopper – did not leave the ground, but the powerful Raptor engine turned off for a short while Tethered to the ground at the SpaceX plant in South Texas.

"Starhopper completed tethered hop. All systems green," SpaceX Chief Executive Elon Musk tweeted Wednesday night.

Musk delivered the good news shortly after his second company, Tesla Inc.

TSLA, + 2.07%

reported some bad news – first quarter deliveries that fell far below analysts' expectations.

The reusable Starship rocket, which has angled halves like something out of a cartoon, can carry up to 100 people and is intended for missions to the moon, and later, March – and back.

Several tethered and suborbital tests are expected to be completed this year, and Musk has said Starship could take its first orbital flight in 2020.
