A New Mission Concept for the Space Infrared Telescope Facility
The Space Infrared Telescope Facility will be a one-meter-class cryogenically cooled infrared astronomy observatory.
A New Mission Concept for the Space Infrared Telescope Facility
This paper describes a new mission concept for the Space Infrared Telescope Facility (SIRTF). In this concept, the observatory is launched with just enough energy to escape Earth's gravity.
Predicting Spacecraft Trajectories
Calculations include drag, nonsphericity, and other perturbations. Artificial Satellite Analysis Program (ASAP) is general orbit-prediction program that incorporates sufficient orbit-modeling accuracy for mission design, maneuver analysis, and mission planning. Suitable for studying planetary orbit missions with spacecraft trajectories of exploratory (mapping) nature. Sample data included for study of drift cycle of geosynchronous station, strategy for mapping Venus by radar, frozen orbit about Mars, and repeat-ground-trace orbit. ASAP written in FORTRAN 77.
