Endeavour Mission

Challenge 1: Mission on Endeavor

T-minus 5, 4, 3, 2, 1, and we have liftoff! The shuttle Endeavour has cleared the tower attached to two exterior rocket boosters and an external fuel tank. The ET had to have enough fuel and power to counter the force of gravity or else, what was the point of wasting all that time and money to build it?
At an altitude of 45 km, the Solid Rocket Boosters would separate as they are no longer required. When the shuttle reaches an altitude of 100 km, the main engine stops firing and detaches from the shuttle. This happens because Endeavour has escaped the Earth's gravity and can now roam around in space. As the shuttle crew is in reach of their target, the mission specialists would take off and perform repairs in the payload bay. MS 1 would operate the Canadarm while MS 2 and 3 would build a replacement piece just in case it is needed. MS 1 would take the items required for the repairs. They are attached to the Canadarm so that they won't lose control of the satellite and drift off into the dark, endless void which we call space. After a certain amount of time, Endeavour begins its descent into the Earth.
