This photo provided by SpaceX shows a prototype of its Mars ship, Starship, that launched on Tuesday, Aug. 5, 2020 in south Texas. Tuesday night's flight lasted barely 45 seconds, but was an important first for SpaceX's Starship. SpaceX chief Elon Musk tweeted: "Mars is looking real." Musk says several more short hops are planned before a test version of Starship aims for a high altitude. The latest prototype is relatively plain: It stands a full-scale 100 feet tall and resembles a steel silo with a cap on top. (SpaceX via AP)
