SpaceX foresees eventually putting a Starship into orbit, and then refueling it with another Starship so it can continue on a journey to Mars or beyond.
The eventual objective is to establish bases on the Moon and Mars and put humans on the "path to being a multi-planet civilization," according to Musk.
"We are at this brief moment in civilization where it is possible to become a multi-planet species," he said. "That's our goal. I think we've got a chance."
