SpaceX's Starship rocket set for historic launch and splashdown.

SpaceX is preparing for the first orbital-velocity launch of its Starship deep-space rocket system, which consists of a first-stage booster called Super Heavy and an upper-stage spacecraft known as Starship. The test flight will use prototypes Ship 24 and Booster 7 and will take around 90 minutes, starting at Starbase, flying east over the Gulf of Mexico and between the Straits of Florida, and finishing off near Hawaii. Both Super Heavy and Starship are designed to be fully reusable, but this will be the only flight for Booster 7 and Ship 24, which will splash down in the ocean.
