Watch: SpaceX prototype Starship rocket just exploded in a big fireball

SpaceX's Starship SN4 prototype launch vehicle just exploded in a huge fireball during a static fire test in Boca Chica, Texas. While the Starship spacecraft is still early in development, the explosion doesn't feel great leading up to the SpaceX-NASA historic launch now scheduled for tomorrow. Scrubbed on Wednesday due to weather, it'll be the first time humans will launch to space from the United States since 2011 and the first time a private company will take humans offworld.
