Making Life Multi-Planetary, Elon Musk
"We are targeting our first cargo missions in 2022 - that's not a typo, although it is aspirational. We've already started building the system - the tooling for the main tanks has been ordered, the facility is being built and we will start construction of the first ship around the second quarter of next year. In about six to nine months we should start building the first ship. I feel fairly confident that we can complete the ship and be ready for a launch in about five years. Five years seems like a long time to me. The area under the curve of resources over that period of time should enable this time frame to be met, but if not this time frame, I think pretty soon thereafter. But that is our goal, to try to make the 2022 Mars rendezvous. The Earth-Mars synchronization happens roughly every two years, so every two years there is an opportunity to fly to Mars. Then in 2024 we want to try to fly four ships - two cargo and two crew."
