It turns out, SpaceX is working on not one, but two Starships at the same time. “SpaceX is doing simultaneous competing builds of Starship in Boca Chica Texas & Cape Canaveral Florida,” SpaceX founder and CEO Elon Musk said in a tweet Tuesday. Musk went on to answer a few questions on Twitter, saying that the competition is really to figure out which location is better for building, and that the answer might be both. SpaceX did not immediately respond to a request for comment. In November, Musk renamed the Big Falcon Rocket to Starship.
