On Thursday night, SpaceX founder Elon Musk shared photos of Raptor rocket engines that recently left the company’s factory in Hawthorne, Calif., headed out to be tested at its facility near McGregor, Texas. “Preparing to fire the Starship Raptor engine,” he said by way of a caption on Twitter.

The photos were interesting, but Musk had additional comments about the engine that revealed much about how the company is proceeding with overall design of the vehicle it will power. SpaceX’s approach seems focused on keeping costs down and moving as quickly as possible towards a launch of the Starship spacecraft and Super Heavy rocket in the early 2020s.

For example, Musk said, “Initially making one 200 metric ton thrust engine common across ship & booster to reach the Moon as fast as possible. Next versions will split to vacuum-optimized (380+ sec Isp) & sea-level thrust optimized (~250 ton).”
