Reusable Space Shuttle

            You may came across many sites explains about the reusable space shuttle but here you can feel the difference. I tried my level best to collect more information about reusable space shuttle.Don't wait here you go for the information about the reusable space shuttle.
             As we all know the first reusable space shuttle was launched in 1981 by the Space giants US.In Spacecraft history it can carry large satellites to and from orbit.The shuttle launches like rocket and lands like an airplane.Discovery,Atlantis and Endeavour are the space shuttles now in operation.
Space Shuttle                   Delivered Year 
Columbia                           March 1979
Discovery                          November 1983
Atlantis                              April 1985 
Endeavour                        May 1991


Orbiter:
             It is the sole controller of the space craft.In short we can say it is the brain as well as the heart of the Space Shuttle.It contains the latest advances in flight control, thermal protection, and liquid-rocket propulsion and it also composed of pressurised crew compartment, the huge cargo bay and the three main engines.
The crew cabin has three levels: 
1)The flight deck--where the commander and pilot control the craft
2)The mid-deck--the galley, toilet, sleep stations, and storage and experiment lockers where found
3)The utility area--for air and water tanks.
External Tank:
                        Its  length of 47 m (154 ft) and a diameter of 8.4 m(27.5 ft).External Tank are made from aluminum alloys, During the first 8.5 minutes space shuttle consumes the fuel of about 1.99 million litres (526,000 gal) .
                        The space shuttle's external fuel tank is the only part of the launch vehicle that currently is not reused. 
Solid Rocket Booster(SRB):
                         There are two SRB's are used in the space shuttle.It provide most power for first 2.5 min of flight.The SRBs take the space shuttle to an altitude of 45 km (28 mi) and a speed of 4973 km/hr (3094 mph) before they separate from Space Shuttle.
                           Normally mission has been planned from 5 to 16 days in duration.But STS 80 stayed in orbit for 17.5 days on a single mission.The smallest crew ever to fly of 2 members and the largest crew member of 8 members.
