space shuttle is such a spacecraft that can perform complicated work and reusable .it is  a most gorgeous version in order to perform perfectly in the universe.space shuttle is known as 'STS' as it combines rocket launch,re-entry space plane and orbital space craft .the main purpose of launching space shuttle is to establish numerous satellites ,generating interplanetary problem and testing astrology un.NASA ,which is famous for space related matter ,funding money from USA .a space craft is usually used for orbital space missions performed by NASA .a space shuttle consists of shuttle stack ,two slender ( SRBs) ,along with orbiter vehicle .OV carries out the crew and payload .Generally it is stacked or closely adjusted with vehicle building.at the starting time the space craft usually stands on a platform and after sometime it is detonated at launch.the shuttle stack launches like a rocket. After launching it lifts of three main engines, two SRBS. Liquid hydrogen and Liquid Oxygen is used on the main tank. After reaching its high speed(7.8 k.m./s) it can cross the low earth orbit. The external tank is used in orbit. Especially 5 or 7 cruise carried by the orbiter. A large cargo is carried by the orbiter which makes it unique than present spacecraft. The most recent developed telescope is Hubble Telescope which is used by this kind of space shuttle to capture many mysterious images of universe In such way a space shuttle works.
