Today, Elon Music revealed his plan to colonize Mars using a new Interplanetary Transport System that's in development. He shared a video that visualizes exactly what the spacecraft will look like, based on CAD models. He plans to build a fleet of these spacecraft and send them to Mars as a group, eventually creating a self-sustaining colony. This is one of Musk's most ambitious plans yet.
Right now they have a constrained budget. But Musk said the first development spaceship will, hopefully, be completed in four years, with the ability to go into orbit. The booster part, he shared, is a scaling up of their current Falcon 9 booster. He said that perhaps a 10-year timeline is a good goal for the project, but it involves a lot of risk so it's unclear exactly what the timeline will be. Dragon 2 will be sent to Mars in a couple years, he said, to help continue keeping the process moving forward.
