BeforeSpaceX's Starship exploded above Boca Chica, Texas, on April 20, it spread debris for miles and caused the Federal Aviation Administration (FAA) to ground the program to determine what went wrong during the test.
Why it matters: While these types of FAA safety investigations are standard for launches that don't go according to plan, this one could delay future Starship flight tests, which may have cascading effects on SpaceX and its partners, including NASA.
