In the space business everything depends on the President, and when a President is going to change, a lot of uncertainty preceeds the last year of any outgoing President. Reagan and Bush Sr. were the last days of cost plus programs, and Clinton ended those kind of Contracts, and began a trend of companies subcontracting work, much of it out of the country. Cost plus was gone, budgets were strained, but that changed aerospace and Space contracts totally, even thru the Bush 2 years. Obama hasn't talked about canceling programs yet, however when you are as liberal as he is, with such a liberal Congress, who knows what they will dump in favor of programs like Health care, or all these bail outs. It may not get cancelled, however stretching the schedule out further is a probabilityy, and I'm not convinced you will not see the shuttle extended to keep flying past 2010. Its replacement is a long ways off, so keeping it flying 5-10 more years seems logical, plus it would keep Rocketdyne active in those systems, which use some of the same major equipment, as the J-2 and RS-68 Delta rockets. Many of the engineers are in all these programs, plus the core of manufacturing experience.
