NASA selects about a hundred men and women as astronaut candidates. If you are selected, you will report to NASA's Johnson Space Center in Houston for training and evaluations, which last two years. If you are a pilot, you will train in NASA's T-38 jet aircraft and shuttle training aircraft at least 15 hours each month.
Mission specialists fly four hours each month.
At the end of the two-year training period, you may be selected to become an astronaut . As an astronaut, you will continue classroom training on the various aspects of space shuttle operations that you started as an astronaut candidate. You will begin training on each individual system in the shuttle with the help of an instructor. After that, you will train in simulators for pre-launch, launch, orbit, entry and landing. Depending upon whether you are a pilot or mission specialist, you will learn how to use the shuttle's robotic arm to manipulate cargo.
