Elon Musk’s plans for the future of SpaceX are riding on Starship and Super Heavy, a fully reusable rocket and booster that when stacked are taller than the State of Liberty and its pedestal. While Starship has flown to high altitudes a number of times, the company has never flown the rocket to space. As early as Thursday, April 20, SpaceX will attempt to launch Starship to orbital velocities from a test site in Texas, with the vehicle circling the Earth before splashing down in waters off the coast of the Hawaii an hour later. A launch attempt on Monday was scrubbed.
