Atmospheric deployment of tethered systems - The proposed TSS-2 flight demonstration

Areas of strong user interest in the atmospheric deployment of tethered systems are addressed. They include hypersonic and aerothermodynamics research to support next-generation aerospace vehicle design, lower thermosphere scientific research supporting global change monitoring and earth systems investigations, and payload recovery/trash disposal from Space Station Freedom. The proposed tethered flight demonstration TSS-2 is described.

The Large Deployable Reflector - A technology development challenge

The proposed Large Deployable Reflector (LDR) telescope is an astrophysical orbiting platform whose aperture is of the order of 20 m, and is dedicated to observations in the IR and sub-mm wavelengths. NASA is currently planning a 5-year technology development program that will allow the requisite hardware and software to reach the state required for economical and reliable implementation. A computer model simulation is envisioned toward this end that will encompass and integrate structural, thermal, control, optics, and systems program elements. Possession of the enabling technology is foreseen for the early 1990s.
