Booster separation motor
The booster separation motors on the Space Shuttle were relatively small rocket motors that separated the reusable solid rocket boosters (SRB) from the orbiter after SRB burnout. Eight booster separation motors were attached to each of the shuttle's two reusable solid rocket boosters, four on the forward skirt and four on the aft skirt. About two minutes into a space shuttle flight, all 16 of these motors were fired simultaneously for 1.2 seconds, providing the precise thrust required to safely separate the spent boosters from the space shuttle's external tank and orbiter, while traveling more than and an altitude of approximately .
The booster separation motors were produced by ATK Launch Systems Group, part of Alliant Techsystems (ATK) Inc., at their facility in Brigham City, Utah.
Booster separation motors weighed when loaded with propellant. Each was approximately long and in diameter.
