Basic Astronaut training begins with an intensive two-year program. During the two years, candidates recieve training in basic science (math, astronomy, physics, geology, meteorology, and oceanography) and technology (navigation, orbital mechanics, and materials processing). Also included in the basic courses are parachute jumping, land and sea survivel techniques, and micro gravity of space flights.
