Space Shuttle’s Reusable Solid Rocket Motor

The space shuttle’s reusable solid rocket motor is the largest solid rocket motor ever flown, the only one rated for human flight and the first designed for reuse.

The space shuttle’s reusable solid rocket motor is the largest solid rocket motor ever flown, the only one rated for human flight and the first designed for reuse. Each shuttle launch requires the boost of two reusable solid rocket motors to lift the 4.5-million-pound shuttle vehicle. During space shuttle flights, solid rocket motors provide 80 percent of the thrust during the first two minutes of flight. Each motor, the primary component of the shuttle’s twin solid rocket boosters, generates an average thrust of 2.6 million pounds and is just over 126 feet long and 12 feet in diameter.
