As the shuttle takes off, Ride is thrust back into her seat by three times the force of gravity. The two solid boosters fall away and parachute into the ocean, where they will be recovered for later use. After about eight minutes, the shuttle's engines cut off.
The big orange fuel tank falls into the atmosphere and burns up. Inside the shuttle, Ride is weightless, soaring 185 miles above the earth.
