Stargazer carrying a Pegasus XL rocket over the Atlantic
Stargazer is a Lockheed L-1011 TriStar built in 1974, that was modified in 1994 for use by Orbital Sciences (now part of Northrop Grumman) as a mother ship launch pad for the Pegasus launch vehicle. As of October 2022, 45 rockets (containing nearly 100 satellites) have been launched from it, using the Pegasus-H and Pegasus-XL configurations. As of 2019, Stargazer was the only L-1011 airframe still airworthy.
