SpaceX launches its biggest, most beefed-up Starship yet on a test flight

At 407 feet (124 meters), the latest model eclipses the older Starship lines by several feet (more than 1 meter) and packs more engine thrust.

The revamped booster sports fewer but bigger and stronger grid fins for steering it back to Earth following liftoff, and a larger and more robust fuel transfer line to feed the 33 main engines. This fuel line is the size of SpaceX's Falcon 9 first-stage booster. The retro-looking, stainless steel spacecraft also has more of everything -- more cameras and more navigation and computer power -- as well as docking cones for future rendezvous and moon missions.
