Castor (rocket stage)
Solid-fuel orbital vehicle component / From Wikipedia, the free encyclopedia
Castor is a family of solid-fuel rocket stages and boosters built by Thiokol (now Northrop Grumman) and used on a variety of launch vehicles.[1] They were initially developed as the second-stage motor of the Scout rocket. The design was based on the MGM-29 Sergeant, a surface-to-surface missile developed for the United States Army at the Jet Propulsion Laboratory.[2][3]
