Clues...

...as to why LM won Orion can be found here.

Not that the reasons behind the decision will matter to some.

About the 'very good' Phase 1 performance

Was Phase 1 the part where LM originally proposed the lifting body concept reentry vehicle?

The lifting body configuration was part of the proposal for the Phase 1 configuration development/trade study contracts.

Aha! I thought so. So all the innovative work that LM had to throw away because NASA had different ideas did some good after all. Since the 'very good' Phase 1 performance was one of the deciding factors in Lockheed's victory over NG.

I've always been curious about that original Phase 1 proposal since detailed information is hard to come by. All I've seen is so far is artwork from Popular Mechanics and the non-lifting body description in astronautix.com.

So what were the empty and gross masses of the liting body, the mission module and the propulsion module? And what was the original LM lunar mission architecture with that lifting body reentry vehicle? Was the three module CM + MM + PM all lifted up together via single launch of a heavy lift version of the Atlas V? What was used for trans lunar injection burn? For lunar orbital capture burn? Did the orginal moon mission architecture have the lunar lander travel independantly to low lunar orbit with it's own Atlas V launch and it's own Earth departure stage? I can't see how the lifting body could be docked with a lander and have the thrust of an Earth departure stage pass through the common center of mass so they must have first linked up in low lunar orbit, right?

Heh, sorry, but you'll have to make do with the publicly available information to answer those questions. That info isn't mine to give out.
