(PHYSorg.com Space & Earth)

For almost a year now, SpaceX has been building a series of Starship prototypes that will test how the system fares when launched to orbit. Coming on the heels of successful hop tests with the Starship Hopper, these tests will validate the spacecraft and its Raptor engines in space. Unfortunately, the company has encountered some hiccups with these prototypes, as the first two exploded during pressure testing.
