The Pegasus is an air-launched rocket developed by Orbital Sciences Corporation (now part of Northrop Grumman Innovation Systems). Capable of carrying small payloads of up to 443 kilograms (977 lb) into low Earth orbit, 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.
After more than 15 years of operation, NASA’s Aeronomy of Ice in the Mesosphere (AIM) spacecraft has ceased operations due to battery issues.
Sub-orbital launch under Rocket Lab’s Hypersonic Accelerator Suborbital Test Electron (HASTE) program, details TBD.
