The Shuttle is being shelved in 2010. The Crew Exploration Vehicle (or CEV) has been designed, approved, budgeted and ground service facilities are being readied.
Unfortunately they must stop use of the current shuttles by 2010 - however the so called CEV or “Orion spacecraft” is now not expected to be ready or usable until something like 2016 - so we have a 5 to 6 year gap....
