> then SLS would represent a ~17 year long program that cost at least 41 billion dollars that netted 5 mission launches
SLS will never be worth it. But I'd discount from that price tag the continuity benefits of keeping the Shuttle folks around, and aerospace engineers employed, across the chasm years of the 2010s.
Yeah, it’d be really nice if we could somehow express the strategic capabilities maintained in these discussions. Because on the face of it, SLS looks terrible, but paying that much to maintain the national capability to make something like the shuttle and SRBs feels reasonable.
Kind of similar to farm subsidies and the strategic implications there.
