The three-stage Pegasus is capable of deploying small satellites weighing up to 1,000 pounds into low-Earth orbit. Pegasus is carried aloft to approximately 40,000 feet over open ocean, where it is released and then free-falls in a horizontal position for five seconds before igniting its first stage rocket motor. With the aerodynamic lift generated by its unique delta-shaped wing, Pegasus typically delivers satellites into orbit in a little over 10 minutes.
