242 seconds (2.37 km/s) Burn time. 123 s. Propellant. PBAN - APCP. The Space Shuttle Solid Rocket Booster (SRB) was the first solid-propellant rocket to be used for primary propulsion on a vehicle used for human spaceflight. [1] A pair of these provided 85% of the Space Shuttle 's thrust at liftoff and for the first two minutes of ascent.
Solid rocket booster. A solid rocket booster (SRB) is a large solid propellant motor used to provide thrust in spacecraft launches from initial launch through the first ascent. Many launch vehicles, including the Atlas V, [1] SLS and Space Shuttle, have used SRBs to give launch vehicles much of the thrust required to place the vehicle into orbit.
The SRB casings were made of 12.7 mm (0.50 in) thick steel and were much stronger than the orbiter and ET; thus, both SRBs survived the breakup of the Space Shuttle stack, even though the right SRB was still suffering the effects of the joint burn-through that had set the destruction of Challenger in motion.

The first occurrence of in-flight O-ring erosion occurred on the right SRB on STS-2 in November 1981. [3]: 126 In August 1984, a post-flight inspection of the left SRB on STS-41-D revealed that soot had blown past the primary O-ring and was found in between the O-rings. Although there was no damage to the secondary O-ring, this indicated that ...
The booster separation motors or BSMs 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 frustum and four on the aft ...
The Single Resolution Board (SRB) is an EU agency that was established in Brussels in 2015 as part of the broader set of reforms known as the banking union. It acts as the bank resolution authority for a subset of banks in the euro area and as the institutional hub of the Single Resolution Mechanism (SRM). Resolution is the restructuring of a ...
