Elon Musk just gave a presentation in Australia, updating SpaceX’s plans for the interplanetary transporter. It seems they are indeed making some meaningful progress… with an aspirational goal of sending to of these rather gigantic landers to Mars in 2022 carrying cargo, and four in 2024… two of which are to be manned. Seems ambitious. But then… this is SpaceX, and they’ve accomplished some amazing things in the field of rocketry. if they’d just stop tinkering with that silly hyperloop and devote the effort and manpower to *this…*
It would be entertaining as hell of SpaceX gets the BFR up and running and shooting prototype interplanetary colonization ships to Mars before NASA even has the SLS ready to go.
