"Stargazer" is an L-1011 commercial transport aircraft modified to serve as the launch platform for Orbital’s air-launched Pegasus rocket as well as a platform for airborne research projects. The L-1011 has been used to successfully launch 32 Pegasus rockets as well as the captive carry flights of the X-34 reusable launch vehicle demonstrator. The aircraft has also been used to conduct various airborne research projects including the NASA Adaptive Performance Optimization (APO) project.
Orbital’s uniquely modified L-1011 offers a variety of options for the installation of research test payloads. In addition to external mounting, platforms can be installed internally, on the upper deck or in cargo compartments. Installation, de-installation and turn around times are significantly reduced due to the adaptability and flexibility of the L-1011.
The advantages of using Orbital’s L-1011 airborne launch and research platform include:
Fully equipped as an airborne platform providing power, data, video monitoring and telemetry transmission,
Efficient design for rapid test equipment installation and removal,
FAA Certification allows worldwide access,
The unique external payload hook system can support an externally mounted pallet for aerial research equipment or for external release,
Launch Panel Operator (LPO) station to monitor and control payload,
Customer-focused flight crew and engineering staff experienced in flight test and airborne research.
