Elon Musk, chief executive of SpaceX, has unveiled the plans for his next spacecraft—codenamed the “Big Fucking Rocket”—which would enable the company to build a base on the moon and colonize Mars. Musk claimed it would also permit commercial travel to anywhere on Earth in less than an hour, in a speech at the International Astronautical Congress in Australia. The Canadian-American business magnate said Friday that he hopes SpaceX can first launch a BFR by 2022, with four in total flying to Mars in the two years afterward.
