Outboard views from a NASA Space Shuttle launch with sound recorded from the SRBs during launch & trip up, and the spectacular fall back to Earth........ . . . . . . . . . . . . . . . . . .
The boosters will propel the Shuttle to 3512 mph (5652 km/h). At 124 sec. after lift off
SRBs have expended their fuel. They separate from the orbiter at an altitude of approx 30,4 mi.(49 km)
After separation, momentum will propel the SRBs for another 70 sec. to an altitude of 44,1 mi (71,6 km)
At an altitude of 2,5 mi.(4.6 km) the nose cap is jettisoned and deploys a pilot parachute.
These immediately deploys the drogue parachute which is attached to the top of the cone-
shaped structure at the end of the booster.
At an altitude of 1,2 mi (2.1 km) the cone separates and this releases three main parachutes.
These chutes will quickly slow the booster's speed from 230 mph (370 km/h) to 51 mph.(82 km/h). A motor nozzle extension is severed by a pyrotechnic charge approx 20 sec. later.
A motor nozzle extension is severed by a pyrotechnic charge approx 20 sec. later.
At approx. seven minutes after liftoff, the boosters impact the Atlantic Ocean.
The splashdown area is a box of about 7 by 10.5 mi (11 by 16.7 km) located about 140 mi (258 km). downrange from the launch pad where 2 retrieval ships collect them.
