Pegasus XL | 8 x CYGNSS

CYGNSS or Cyclone Global Navigation Satellite System is a NASA developed system to improve hurricane forecasting. It is a constellation of 8 small observation satellites, 27.5 kg each, that will make accurate measurements of ocean surface winds in and near the eye of the storm throughout the lifecycle of tropical cyclones, typhoons & hurricanes.

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.

Orbital ATK Inc. was an American aerospace manufacturer and defense industry company. It was formed in 2015 from the merger of Orbital Sciences Corporation and parts of Alliant Techsystems. Orbital ATK was purchased by Northrop Grumman in 2018.
