The Orbital Sciences X-34 was intended to be a low-cost testbed for demonstrating "key technologies" that could be integrated into the Reusable Launch Vehicle program. It was intended to be an autonomous pilotless craft powered by a " Fastrac " liquid-propellant rocket engine, capable of reaching Mach 8 and performing 25 test flights per year.
Stargazer was also used for captive tests and transportation of the X-34 hypersonic research aircraft; however, the drop tests used Balls 8. Stargazer in Orbital Sciences livery launches Pegasus carrying the three Space Technology 5 satellites in 2006. Pegasus launches using Stargazer are usually conducted from Vandenberg Air Force Base.
Orbital Science made a number of strategic acquisitions in the 1990s and 2000s to strengthen its position in the satellite market. In 1994, Orbital completed acquisition of Fairchild Industries' subsidiary Space and Defense Corporation, and merged the Fairchild Space business with its own satellite design and manufacturing division.

To launch the added weight, Orbital used the more powerful Castor 30XL solid-fuel rocket as a second-stage. Starting in mid-2025, a further enlarged "Mission B" Cygnus will be introduced with a length of 7.89 meters (25.9 ft), a payload capacity of 5,000 kilograms (11,000 lb), an increase of 19.5%, and a pressurized cargo volume of 36 cubic ...
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 ...
