The Graphite-Epoxy Motor (GEM) is a family of solid rocket boosters developed in the late 1980s and used since 1990. GEM motors are manufactured with carbon-fibre-reinforced polymer casings and a fuel consisting of HTPB-bound ammonium perchlorate composite propellant. GEM is produced by Northrop Grumman Space Systems. [1]

The Star 30 (TE-M-700-2) is a solid fuel motor, with the 30 representing the approximate diameter of the stage in inches. [37] Different versions (A, B, C, E and PB) were used as an apogee motor for satellites such as G-STAR, Skynet 4, Koreasat or the HS-376 satellite bus. [37] Star 30E was used by the ORBEX small orbital launcher. [37]
[1] [2] Boosters are traditionally necessary to launch spacecraft into low Earth orbit (absent a single-stage-to-orbit design), and are especially important for a space vehicle to go beyond Earth orbit. [citation needed] The booster is dropped to fall back to Earth once its fuel is expended, a point known as booster engine cut-off (BECO). [3]
The CASTOR 1200 motor is a proposed booster based on the Space Shuttle Solid Rocket Booster and was intended to be used as the first stage of the OmegA's heavy configuration. The inaugural flight of the new motor was suggested to occur in the 2020s. It has also been proposed to replace the 5 segment RSRMVs on the Block 2 Space Launch System.
A solid rocket booster (SRB) is a 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.
Solid-propellant rockets or solid-fuel rockets have a motor that uses solid propellants, typically a mix of powdered fuel and oxidizer held together by a polymer binder and molded into the shape of a hollow cylinder. The cylinder is ignited from the inside and burns radially outward, with the resulting expanding gases and aerosols escaping out ...
The Taurus launch vehicle, later renamed [1] Minotaur-C (for "Minotaur-Commercial"), was the first of the Minotaur vehicle family, and the first ground-launched orbital booster developed by Orbital Sciences Corporation (OSC), derived by adding a solid booster stage to the air-launched Pegasus rocket. The first flight, sponsored by DARPA, was in ...
