SpaceX has been very busy lately with the development of its Starship prototypes. Based on recent activity at its Boca Chica facility, and recent images provided by Musk himself, it looks like they are about ready to make their biggest leap yet. Yesterday, on Oct. 14th, Musk announced that the eighth prototype of the Starship (SN8) has received the three Raptor engines it will use to make its planned 15.25 km (50,000 ft).
