This is an overview of the operations the SpaceX ITS will take when it
departs from Earth for its #JourneyToMars.
- Passengers launch aboard the Mars spacecraft.
- Once the Mars spacecraft is in orbit, multiple tankers are sent
into orbit to refuel the Mars-bound spacecraft. (Elon said they
would refuel Mars-bound spacecraft with three to five propellant
tankers, depending on travel time and spacecraft cargo.) These
propellant tankers launch on the same reusable booster as the Mars
spacecraft, and the tankers themselves will land at the launch site
for rapid reuse.
- As soon as all the necessary propellant has been transferred, the
Mars spacecraft will perform its TMI burn.
- The Mars spacecraft (and its passengers or cargo) spend the next
few months in interplanetary space.
