The story of what comes next is complicated. About 6 years ago, Bush cancelled the shuttle program
(with a planned ~5 year phase out), partly as a result of the Columbia accident, and partly because the
shuttles were getting old. At that time, Bush and NASA tried to start a new program to replace the shuttle
which would first take people back to the Moon (by ~2020), and then on to Mars (in the 2030s). NASA
began work on a new "Constellation" program which would have comprised a new heavy launch vehicle (the Ares),
a crew command ship (Orion), and a lunar lander (Altair). There were similarities to the Apollo program
but with new design features that would enable the same technologies to carry astronauts all the way to
Mars once the Moon had been reached.
NASA ran into technical and moreover financial difficulties developing Constellation in ~2008/2009 and Obama
called for a review. The result of that review (the Augustine report) led to no funding for Constellation in FY2011,
mainly due to budgetary issues. NASA had estimated the cost for the new program as $100 billion in the
first 10 years, i.e. just to get back to the Moon, which meant that it would probably be more like $200 billion.
I think the current plan is to continue development of the Orion crew vehicle, and kick the can down the road
by a few years on the decision re the development of the Ares series of launch vehicles.
The Museum of Flight up here is getting the full scale training fuselage so its not a total bumer but it would have been nice to get the real thing.
Hahaha! Don't go giving them ideas now.
