VSE Costs Climbing?

Editor's update: seems that there is a lot of hallway chatter at MSFC - and elsewhere - about the advisability of switching from RS-68 engines to RD-180s for the CaLV - the prime issue being performance and the smaller booster diameter you could get (back to 27 feet) by going with RD-180s. There is also hallway chatter about the notion of dumping the CLV alltogether and considering an EELV such as the Atlas V. Seems that the current CLV has some difficulties (as designed) in getting the current CEV (as designed) into space.

Editor's note: Word has it that internal studies done by/for Scott Pace's PA&E office show a growth in projected costs to complete the CEV program - by as much as $10-15 billion. In addition, individual lunar missions using one CEV, CLV, CaLV, LSAM, LSAS, etc. are now estimated to cost $5 Billion each. By comparison, Space Shuttle missions cost $0.5 billion each.

NASA News Conference With Mike Griffin: Exploration Systems Architecture Study (Transcript) (Sep 2005)

"As to what it's all going to cost, our estimates are about--that it will cost for the first human lunar return, it will cost about 55 percent measured in constant dollars of what Apollo cost spread out over 13 years. Apollo was done in eight years. So, spreading it out over 13 years, it will cost about 55 percent of what Apollo cost, a specific number in today's dollars, about $104 billion for the first human lunar return along the lines of the architecture you saw today."

Editor's note: That was then, this is now ...
