NASA SPACE SHUTTLES
The Space Shuttle
     NASA space shuttle is the worlds first reusable spacecraft, and the first spacecraft that can carry satellites from orbit and to orbit. There are four space shuttle orbiters now in operation. These are Columbia, Discovery, Atlantis and Endeavour. These are designed to fly at least 100 missions in there time with NASA. The space shuttle consists of three major components: the orbiter, a large fuel tank, and two solid rocket boosters. the orbiter is designed to house the crew, the fuel tank holes all the full that goes to the main engines, and the two solid rockets provide the lift so the shuttle can take off. The length of the space shuttle is 56.14 meters (184.2 feet), the Height of the orbiter on the runway is 17.27 meters (56.67 feet), wingspan is 23.79 meters ( 78.06 feet), and the weight of the space shuttle at liftoff is 4.5 million pounds and at the end of the mission 230,000 pounds.
 

The Power for The Space Shuttle
      The Power of the Space Shuttle is from the liquid fuel rocket engines mounted in the rear of the space craft. These are fed with fuel from the liquid fuel tank and strapped to the underside of the shuttle. Each of the fuel those fuel tanks are solid fuel rockets. The space shuttle also has two engines in the tail, called orbital maneuvering engines. These are used for adjustments for steering. The space shuttle is launched like a rocket with its three rear engines powered by the fuel tanks. The shuttle takes an up ward thrust of 1.1 million pounds. After two minutes of lift off the two solid fuel  rocket boosters break off and return to earth.
 
 

The Cargo Bay Inside the Shuttle
    The Space shuttles can carry all kinds of things to earth. It carries several satellites, telescopes, and television screens to show the arms as it operates. The Cargo Bay doors open once in space and release heat that got built up inside the space shuttle and so they can work on satellites. Once open they use remote controlled arms guide with the help of the televisions to help repair and work on the satellites. The Cargo Bay is very important in the space shuttle and makes everything easier to do.
