It looks like Congress’s insistence that NASA start building a heavy-lift vehicle now is leading the agency toward a very expensive dead-end project that will cost $11 billion but do little to advance that august body’s supposed goal of sending humans out beyond Earth orbit. Chris Bergin over at NASASpaceflight.com has a detailed explanation here; Henry Vanderbilt of the Space Access Society has provided this more succinct summary:
Early word is, it’s an UGLY plan (a good match for the mandate): Â Have the existing contractors build a hasty 70-ton payload Shuttle-Derived launcher using a pair of old-style 4-segment solids and three surplus Space Shuttle Main Engines, then fly this four times starting in 2016 (using up the existing SSMEs.) Â Then, after spending $11.5 billion (ignoring the near-certain overruns) for just four flights, shut this project down and start all over, with a “competition” between several different 130-ton capacity heavy lifter concepts.
Dumber than dirt? Absolutely. But, it’s perhaps the only way that NASA can try to meet the Congressional mandate to build a HLV it doesn’t immediately need using space shuttle technology it is trying to abandon by an unrealistic deadline. And because it doesn’t produce a 130-ton vehicle by the end of 2016 as Congress mandates, the plan doesn’t even really do that.
Vanderbilt has sent out an action alert urging people to call their Congressmen urging them to oppose the Space Launch System program as currently configured and allow NASA to hold an open competition to solicit proposals for a new HLV. It is reproduced in full after the break.
