Hi Senthil,
The parachute in the shuttle is an aid to assist the braking system. The shuttle enters the atmosphere like a glider and lands at relatively high speeds, while it does not have conventional aircraft-like landing gear. That's why shuttle deploy a parachute while landing. It is deployed only at touch-down. Hope this is clear

The parachute is released after the craft touched the ground. This is done to reduce the momentum and hence speed . Many fughter jets also use the same technique. The landing is similar to any other aircraft landing.

Ha ha ha ha ha ha uggh...sorry, I just couldn't control my laughter.
Dear Senthil, most of the aircrafts & space crafts which tarvel at high speed requires a chute to exert some control over the landing.... Its not because it has been dropped from the space station.
Chute only operated where there is air pressure and gravity (some force). A parachute is of no use in outer space.

Why don't they use DISK brake, which is very efficient in my PULSAR Bike

You see this on aircraft carriers also, where you have shorter runways and the high tech aircrafts, which come in a tremendous speed have to be slowed down by releasing the parachutes. Otherwise, they will land up on the other side of the runway on the carrier - which in this case is not some grassy patch but sea.

Parachute is to reduce the speed when the shuttle touches the runway at very high speed. It enters the atmosphere at 5times greater than the sound speed.
