Follow Elon Musk's Twitter and SpaceX's Twitter for more updates on the Raptor engine's progress.

"First firing of Starship Raptor flight engine!"

SpaceX's Starship is a rocket the company is designing with the goal of transporting humans and cargo to Mars.

A "hopper" prototype that SpaceX will use to test the Starship design on short flights within Earth's atmosphere will have three Raptor engines.

The entire hollow nosecone broke off, and at the time, Musk said it would take a few weeks to fix.

A prototype version of the Starship, dubbed the Starship Hopper, is under construction at another SpaceX facility on South Texas' Gulf Coast.

'Initially making one 200 metric ton thrust engine common across ship & booster to reach the moon as fast as possible, ' Musk tweeted alongside the footage from the recent tests.

Both of these vehicles will be reusable and Raptor-powered. The Super Heavy mounts 31 Raptor engines, while the Starship has seven.

Back in December, Musk tweeted that he had redesigned the engine.

SpaceX has been developing the Raptor engine over the last few years as part of its plan to eventually send tourists to Mars.

Showing the engine in action on Twitter, the entrepreneur said he was "so proud" of the work carried out by his team at SpaceX, who recently learned that workforce numbers at the company would be cut by around 10pc. Merlins use kerosene and liquid oxygen (LOX) propellants, for example, whereas Raptors use liquid methane and LOX.

The first rocket firing happened right around 1AM Central Time on the morning of Sunday, February 3rd, 2019.
