In March 2015 there will be an enhanced Space Shuttle released called the Orion. It will carry more cargo than any other shuttle to the Space Station that might be done around 2020 or so. Cross your fingers and hope that it does not explode like the Challenger.
However, the Orion will cause serious problems in the space program. At 2010 NASA will work only on Orion and on nothing else. Actually Orion will replace the Space Shuttle! Let’s hope this works
