Optical Design and Testing of a Fast, Large Aperture, Infrared Space Telescope,um aperture 2.5 metre with an F/1.2 primary and wavelength coverage from λ = 2 to at least 40 .m, and possibly to 100 .m. Compactness, low thermal emission from the optics and structure, diffraction limited imaging at λ = 2 .m, and sensitivity to misalignment aberrations and manufacturing errors wer

Aspects of Data Flow for an Edison-Type Observatory,e in the near (2–50 .m) infrared and having a mission lifetime often to twenty years. This would be achieved using a passively cooled mirror and an instrumental package whose passive cooling is aided by a mechanical cooler. The data-flow to and from such a telescope would be large and thus the data-

Stellar Infrared Astronomy with Edison,an be extracted from such observations. Some emphasis is placed on the possibilities of stellar IR astronomy using a large space-borne telescope, especially with respect to the much better spatial and spectral resolution of such a telescope compared to the current generation of ground-based and space IR telescopes.
