Plans for the space shuttle started in 1970 with the first orbiter, Enterprise, debuting in 1976. Key events included the first American woman, Sally Ride, going to space in 1983, the Challenger explosion in 1986 due to an O-ring failure, and the Columbia disaster in 2003 when heat tiles were damaged on launch. The last space shuttle launch was in 2011, ending the 30-year program.
11. 3 main parts: Orbiter (houses the crew), Large external fuel tank ( holds fuel for main engines, and it burns up in the atmosphere after each launch), and the Two solid rocket boosters (provides most of the shuttle’s life during the first two minutes)
12. Has a robotic arm so the crews can move large objects and it helps them with their spacewalks
15. Equipment Bay: smaller lower deck can’t go there unless floor panels of the middeck are lifted
16.
17. First stage Ascent: after 2 minutes, shuttle is 45 kilometers and traveling 4,900 kilometers per hr. Booster casing are jettisoned, and gets parachuted into the Atlantic Ocean, recovered by special NASA ships to be refilled with fuel
30. Cause was due to an o-ring failure in right rocket booster, cold weather was the contributing factor
