NASA Readies Discovery Shuttle For Final Flight 153
gabbo529 writes "After 38 trips, 352 days in orbit and more than 5,600 trips around the Earth, the space shuttle Discovery is preparing for its final launch. Since its creation, it has flown to orbit more than any other craft. It has set a number of precedents including first craft to feature a female shuttle pilot and female shuttle commander (Eileen Collins), the first African American spacewalker (Bernard Harris) and the first sitting member of congress to fly in space (Jake Garn). In its final foray into space, the Discovery will set another precedent when it flies the first humanoid robot to fly in space, Robonaut2."

False. Orion has not been cancelled. The most recent NASA authorization act passed last year authorizes over $3.6 billion in funding to develop the vehicle over the next 3 years. The Ares I/V launch vehicles are what was cancelled.

The shuttles are not reusable in any real cost saving sense. They have to have many tiles replaced, the main engines replaced, and numerous other little odds and ends. The SRBs are one of the shuttles main failings, SRBs are cheap but notice that no one else uses them for a man rated launcher.
The Shuttle will not find a buyer, it is not cost effective and never was.

Orion+Ares 1 wasn't going to be finished until 2017 at the earliest.
The first test-article of Dragon has flown, and its launch vehicle (the long pole of the system) has flown twice. Everything I hear about the Boeing offering is going well, and will probably be on a Delta IV (a flying vehicle). Orion is even still alive, and Lockheed is planning to fly a version on an Atlas V (again flying).
No one is ready to go to the moon yet, but developing a real multi-supplier infrastructure to get to LEO is a critical first step. Even more importantly, if the next administration changes plans again, the infrastructure will remain in place and make it easy to do whatever the powers that be decide.

Working for a DoD contractor that did work for Orion, I can say for certain it was cancelled (even if they do not call it that). There's no more work being done for a very critical portion of the capsule right now that our company was responsible for, and that stuff is now sitting in the corner of the lab, the responsible engineers are off working on other things.
The two words that are a death knell for any project are: "Stop Work"
Gotta post AC, simply because I cannot speak for my company, but I have eyes and can plainly see what is going (or not going) on.

SpaceX Dragon: $300-$400m (est.) per flight (...) The SpaceX Dragon isn't significantly cheaper than the shuttle, and is again, far less capable than the Shuttle, and is still an unproven design
At least for the cargo operations, SpaceX will deliver 12 flights for 1.6 billion. That works out to about $133m per flight. And it is tested [physorg.com] so they have a working rocket and a working capsule. How reliable they are can be questioned, but the design works.

I think the figures you have for the Shuttle are low. Endeavor cost $ 1.7B to build from spare components. That does not include the cost to acquire those components, and it assumes the design has been paid for already.
From Wikipedia [wikipedia.org]: Roger Pielke has estimated that the Space Shuttle program has cost about US$170 billion (2008 dollars) through early 2008. This works out to an average cost per flight of about US$1.5 billion.
