In order to send one BFS to Mars, we’d need four other spaceship (fuel tankers) launches. But with a fully expendable vehicle, the cost would be relatively small to do this.

  1. Booster accelerates the BFS and tankers and returns back to the launch site on Earth.
  2. The ship flies into Earth orbit.
  3. Tankers refill the ship and return to the Earth.
  4. Refilled ship travels to Mars.
  5. Ship refilled on Mars using local resources.
  6. Ship performs Mars ascent and direct return to Earth. “Because Mars has lower gravity than Earth, you do not need a booster – you can go all the way from the surface of Mars to the surface of Earth just using the ship.” says Musk.
