SpaceX has done it again – a second ‘hop’ flight in under a month for its Starship prototype. This was a 150 meter (just under 500 foot) test flight from its Boca Chica, Texas development site. The prototype used in this instance was SN6, a more recent model than the SN5 test article that SpaceX used to complete a similar test at the beginning of August.

The hop flight is a key part of its testing program for Starship, and its Raptor engine. These prototypes are equipped with only one such engine, but the final production version will have six, including three designed to fly in Earth’s atmosphere, and three to be used while the vehicle is in space.
