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 them provided 85% of the Space Shuttle's thrust at liftoff and for the first two minutes of ascent.
The historic Space Shuttle reused its Solid Rocket Boosters, its RS-25 engines and the Space Shuttle orbiter that acted as an orbital insertion stage, but it did not reuse the External Tank that fed the RS-25 engines. This is an example of a reusable launch system which reuses specific components of rockets.
The Heavy Lift Launch Vehicle was a study by NASA to turn the Space Shuttle launch stack into a dedicated uncrewed cargo launcher. The external tank and Space Shuttle Solid Rocket Boosters (SRBs) would be combined with a cargo module that took the place of the shuttle orbiter and included the Space Shuttle Main Engines.
In 2013 SpaceX was testing reusable technologies both for its first-stage booster launch vehicle designs (with three test vehicles: Grasshopper, F9R Dev1, and F9R Dev2) – and for its new reusable SpaceX Dragon 2 space capsule (with a low-altitude test vehicle called DragonFly).
The Space Shuttle, composed of an orbiter launched with two reusable solid rocket boosters and a disposable external fuel tank, carried up to eight astronauts and up to 50,000 lb (23,000 kg) of payload into low Earth orbit (LEO).
The booster casings for the Space Shuttle Solid Rocket Boosters were recovered and refurbished for reuse from 1981 to 2011 as part of the Space Shuttle program. In a new development program initiated in 2011, SpaceX developed reusable first stages of their Falcon 9 rocket.
The Reusable Booster System (RBS) was a United States Air Force research program, circa 2010 to 2012, to develop a new prototype vertical-takeoff, horizontal-landing (VTHL) [1] reusable booster and a new prototype expendable second stage to replace the existing Evolved Expendable Launch Vehicles (EELV) after 2025. [2] The program was ...
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 skirt.
