SpaceX hopes to land at least two cargo missions to Mars a mere five years from now. The aerospace company's chief, Elon Musk, discussed its plans at the International Astronautical Congress (IAC) in Australia. He talked about how SpaceX intends to use the BFR, the massive rocket it's developing, to fly Martian settlers to their new home and to take people anywhere on Earth in under an hour. In addition to landing two cargo missions on the red planet by 2022, it hopes to be able to confirm sources of water and potential hazards by that time. SpaceX also plans to start building mining, power and life support infrastructure that year to prepare for the first settlers that could arrive as soon as 2024.
