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?
