SpaceX CEO celebrated the first test firing of a full-scale, built-for-flight Raptor engine for his Starship super-rocket in the usual way tonight: by tweeting about it.

“So proud of great work by @SpaceX team,” Musk wrote in a series of tweets from SpaceX’s test facility near McGregor, Texas.

Scaled-down versions of the methane-fueled Raptor rocket engine went through testing as far back as two and a half years ago, but Musk said this weekend’s test marked the “first firing of Starship Raptor flight engine.”
