A new photo shows just how big SpaceX's Starship Mars-colonizing vehicle will be.
SpaceX founder and CEO Elon Musk tweeted an image Sunday (May 3) looking up at the belly of the latest Starship prototype, the SN4, which is on the test stand at the company's South Texas site. The shot shows the SN4's single Raptor engine, looking extremely lonely in the center of a 30-foot-wide (9 meters) expanse.
"SN4 fire soon. Raptor looks so smol," Musk wrote in the tweet.
