I know, this should probably be a part of the SpaceX main thread, but I couldn't resist!  T-3 hours to Elon's talk!

A couple of handy links:

Any of the links in the comments here: https://www.reddit.com/r/spacex/comments/54itnx/rspacex_mars_architecture_announcementiac_2016/

HYPE!

 

Sad, looks like the virgin galactic thing isn't being streamed.  Fingers for BO's being streamed.

Why would it not be reusable, if they make the effort in the video to show it returning to Earth...? :wink:

A much more interesting question for me, though: anyone got a link to the IAC live feed that doesn't require Flash Player? I'm stuck on a machine that doesn't have it and cannot install it. The link supplied by IAC requires Flash.

Ah nevermind, there's a youtube mirror directly from SpaceX. Sweet! :)

Yeah, the whole thing looks too sci-fi to be realistic: those solar panels, the massive windows, landing on the launch pad and relaunching immediately, a single tanker to refuel... and the terraforming. There's too much artistic license in there to take it seriously.

Those 42 engines seem very close together. Definitely no room to all gimbal. So either they only gimbal the center ones (which seem to have a bit more room) or they control trajectory by throttling, which seems tricky.

I like that they used a moon gravity assist to get to mars.

 

But how can the booster land on the same launchpad?   It must either SSTO or turn around in order to do that, dV requirement looks to be huge for both of those options..

It doesn't SSTO. It should have pretty much the same profile as the F9 RTLS.

I'm more dubious about landing on the launch mounts. If I get that right, that means no landing legs on the booster. Ballsy !

IMO, the booster isn't a SSTO with an MCT on top.  The MCT launch partially fuelled, then uses most of its fuel to insert into orbit.
