SpaceX fired the first firing of its Raptor vacuum engine while integrated into a Starship vehicle. The engine is used in the vacuum of space.
Meanwhile, Elon Musk tweeted that Starship No. 20 could be ready for a suborbital flight next month. The vehicle would take off from Boca Chica, Texas and land in the Pacific Ocean near Hawaii.
The flight is dependent upon approval by the Federal Aviation Administration, which is considering SpaceX’s plan to expand its Texas facility to accommodate launches of Starship and Super Heavy. FAA held two public hearings last week about the plan.
SpaceX is moving ahead with development of the Boca Chica site, which it has dubbed Starbase, despite a lack of approval from the FAA.
