On Saturday, shuttle Discovery is going to perform the most spectacular performance of docking at the International Space Station.

One must remember that Discovery was the first of its kind orbiter which went ahead with its nose-over-tail backflip. It took place some 600 feet below the outpost. It is part of the new heat shield inspection procedure that helped the shuttle to flee the flight after the Columbia accident took place.

Said LeRoy Cain, deputy shuttle manager that Discovery has given them the ability to look forward and now they can make sure that the vehicle has a proper mission to where ever they want it to be and come back to Earth as well.

Till now, all the indicators show that everything is fine in Discovery and it will be going on its final flight after it went for its launch from the Kennedy Space Center. Cain also informed that unlike last time, even if the debris on the external tank are loose this time, they are not going to as much force as they did last time.
