Small-Class

Overview

Pegasus was specically developed to provide cost-effective access to space for the small satellite

community. The Pegasus air-launch system is the industry’s workhorse, providing launch services for

technology demonstration, scientic investigation, remote sensing and communications missions. The

three-stage Pegasus boosts small satellites weighing up to 1,000 pounds (450 kilograms) into low-

Earth orbit. Pegasus is carried aloft by an L-1011 carrier aircraft to approximately 40,000 feet (12,000

meters) over open ocean, where it is released and then free-falls in a horizontal position for ve seconds

before igniting its rst stage rocket motor. In a typical mission Pegasus delivers its payload into orbit in a

little over ten minutes.

System Features

• Inertially guided three stage solid rocket propulsion

• Horizontal satellite integration and simplied launch operations

• Carrier aircraft provides on-board payload monitoring and control

• Air-launched mobility enables launch from anywhere, worldwide:

- Demonstrated launch capability from U.S. Air Force Western Range (WR), Eastern Range (ER),

NASA’s Wallops Flight Facility, Canary Islands and Kwajalein launch sites

- Flight-proven with a demonstrated success record:

- 42 missions conducted

- 28 consecutive fully successful missions

• Flexibility to support unique user needs

World's leading small-class space

launch vehicle.

42 missions conducted; awless record

since late 1996.

Launches conducted from California,

Virginia, Florida, the Canary Islands

and the Kwajalein Atoll in the Marshall

Islands.

Pegasus "Firsts"

• World's rst privately developed space

launch vehicle.

• Maiden 1990 mission marked the

rst all-new, unmanned space launch

vehicle developed in the U.S. in more

than 20 years.

• First winged vehicle to accelerate to

eight times the speed of sound.

• First air-launched rocket to place

satellites into orbit, using its carrier

aircraft as an "air breathing reusable

rst stage."
