The Taurus rocket is a four stage, solid fuel launch vehicle built by Orbital Sciences Corporation. It is based on the air-launched Pegasus rocket from the same manufacturer. The Taurus rocket is able to carry a payload of around 1,350 kg into a low Earth orbit. First launched in 1994, it has successfully completed a total of six out of seven military and commercial missions.[1]

Stages
The Taurus first stage, a Castor 120 made by Thiokol, is based on a Peacekeeper ICBM first stage. Stages 2 and 3 are Orion-50s (like the Pegasus-1 but without wings or stabilisers), and stage 4 is an Orion-38 like a Pegasus-3.[2]
