Musk revealed the stainless steel monstrosity during a presentation at SpaceX’s Boca Chica, Texas testing site on Saturday. The hope is that it’ll one day allow up to 100 passengers to travel to the Moon, Mars, and beyond.

The record-breaking rocket will eventually be 160 feet tall and twice as powerful, according to Musk, as NASA’s retired Saturn V rocket that took American astronauts to the Moon during the Apollo missions.
