Pegasus
Description
Pegasus is an air-launched rocket developed by Orbital Sciences Corporation and now built and launched by Northrop Grumman. The vehicle consists of three solid-propellant stages and an optional monopropellant fourth stage. Pegasus is released from its carrier aircraft at approximately 40,000 ft (12,000 m), and its first stage has a wing and a tail to provide lift and attitude control while in the atmosphere. Notably, the first stage does not have a Thrust Vector Control (TVC) system. Pegasus is the world's first privately developed space launch vehicle.
