I was doing some research for a space piece I’m working on for the summer issue of The New Atlantis, and ran across this old post from five years ago, when I took apart one of Gregg Easterbrook’s nonsensical space policy columns:
He’s doing something worse than comparing apples to oranges–he’s comparing space capsules to commercial airliners. There is no way to infer the costs of one from the other–they are totally irrelevant to each other. One carries hundreds of people, has to fly thousands of times, provides its own propulsion, has to meet all requirements of FAA certification. The other is simply a can that carries four people or so, with basic subsystems like a reaction-control system, avionics, life support, with thermal protection and a recovery system if it’s going to do an entry. And in fact, it’s also “well-understood engineering,” and has been since 1968 or so. It may be expensive, but there’s no way to tell by looking at airliners.
The best way to tell is to do a parametric cost analysis on it. It’s basically an upgraded Apollo capsule (and perhaps service module for modest propulsion and additional consumables). We know how much that cost the first time, and it should be easier now, particularly considering the technology advances over the past four decades (e.g., computer microization). If NASA can’t develop that vehicle in a few years for a few billion, it should be disbanded.
Well, it’s been a few years, and more than a few billion…
