SpaceX Dragon derived lander launched by SLS
« on: 07/17/2017 10:17 PM »
NASA doesn't have the budget to build a lunar Lander; surely SpaceX could quote for a fix price contract to design and build a Dragon 2 derived (apollo style) lunar Lander to be launched by SLS?

I'm thinking a stripped down Dragon2 with no heat shield as the upper stage and another ring of Draco’s with 3/4 legs for the lower stage. All the components our being developed anyway.

NASA still gets to use the SLS and Orion, SpaceX gets a new revenue stream.

Why is nothing like this being proposed? What am I missing?

Extensively discussed elsewhere, an unmodified Dragon v2 with a trunk turned into a fuel tank (discarded before touchdown) could land on the Moon, with a drop tank and legs on the trunk a Dragon v2 could both land and launch again from the Moon into lunar orbit.

No proposal because there's no plans (as of now) for NASA to go to the Moon.

Why would SpaceX do this? It's a dead end. It would distract them from development of a MUCH more capable "lunar lander" called ITS...

Also, "Rockets and rocket parts are not like LEGO elements"

Because it won't work on many levels
NASA would have to hold an open competition
Spacex would not build such a kludge

There was a thread about this earlier this year. We more or less came to the conclusion that the Dragon pressure shell and Draco landing thrusters could be adapted; but most everything else would be new-build. Less expensive than a complete 'clean-sheet' design, but still a complicated thing. Boeing had some designs for a single-stage crewed Lander a couple years ago. All SpaceX would have to do is follow the basic concept, but compete for a lower-priced version.
