This is the space shuttle few days back started his Voyage to space. This has made many trips successfully.
But this trip will be a loss to U.S. and to this world. The shuttle probably will not have his safe landing. It may be collapsed in the sky.
This may be because of Bin Laden killing and a revenge from pakistan with china. I suspect the recent visit of pakistan leaders at china on this issue. Their can be a plot to disaster this shuttle by purchasing Missile and it can be used from some other country to collapse the shuttle on its way to earth.
The time in which it has been sent to space is not right so this is my prediction .
NASA must alert endeavour team and not to reveal the correct time of its return to earth.
