A pair of them provided 85% of the Space Shuttle's thrust at liftoff and for the first two minutes of ascent. After burnout, they were jettisoned, and parachuted into the Atlantic Ocean, where they were recovered, examined, refurbished, and reused. The Space Shuttle SRBs were the most powerful solid rocket motors to ever launch humans. [2]
The mission used Space Shuttle Challenger, which lifted off from launch pad 39B (LC-39B) on January 28, 1986, from Kennedy Space Center, Florida. The mission ended in disaster following the destruction of Challenger 73 seconds after lift-off, because of the failure of an O-ring seals on Challenger ' s right solid rocket booster, which led to ...
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 1,300 metres per second (2,900 mph) and an altitude of approximately 44 ...
The Solid Rocket Boosters (SRB) provided 71.4% of the Space Shuttle's thrust during liftoff and ascent, and were the largest solid-propellant motors ever flown. [5] Each SRB was 45 m (149.2 ft) tall and 3.7 m (12.2 ft) wide, weighed 68,000 kg (150,000 lb), and had a steel exterior approximately 13 mm (.5 in) thick.
The SRMU's fuel geometry is designed to generate highest thrust before 40 seconds, and to rapidly decrease thrust after 120 seconds. [3] Two SRMUs provide all of the Titan IV-B's thrust at liftoff and function as a "stage 0"; the LR87-AJ-11 on the core ignites at T+131 seconds, 15 seconds before booster separation. [6]
The longest orbital flight of the Shuttle was STS-80 at 17 days 15 hours, while the shortest flight was STS-51-L at one minute 13 seconds when the Space Shuttle Challenger broke apart during launch. The cold morning shrunk an O-Ring on the right Solid Rocket Booster causing the external fuel tank to explode.
The Space Shuttle Challenger was destroyed 73 seconds after lift-off on STS-51-L at an altitude of 15 kilometers (49,000 ft). The investigation found that cold weather conditions caused an O-ring seal to fail, allowing hot gases from the shuttle's solid rocket booster (SRB) to impinge on the external propellant tank and booster strut.
The Orbital Maneuvering System (OMS) is a system of hypergolic liquid-propellant rocket engines used on the Space Shuttle and the Orion spacecraft.Designed and manufactured in the United States by Aerojet, [1] the system allowed the orbiter to perform various orbital maneuvers according to requirements of each mission profile: orbital injection after main engine cutoff, orbital corrections ...
