Book 1996ge which has, over the past several years,seen such impressive advances in technology: large-scale detectorarrays, new designs for cooling in space, lightweight mirrortechnologies. Scientific cases for observing the cold universe areoutstanding. Observations in the FIR/Submm range will provide answe

Solar System Observations and Future Missions,are explored, and a number of observations that could enhance our understanding of Solar System objects are suggested. Finally, the adequacy of future space missions in this respect is discussed. The specific cases of ISO, FIRST and the proposed Edison are considered.

,SIRTF — The Moderate Mission,nd to dramatic rescoping of others; SIRTF is in the latter category. This paper describes the resulting redefinition of SIRTF and the technical innovations which have made it possible to package SIRTF’s key scientific capabilities into the envelope of a moderate-class mission.

CREST

Detection Limits in the Far Infrared,ton-background-limited performance and hence very deep detection limits. The dominant noise sources — photon noise, confusion by distant galaxies, and confusion by IR cirrus — scale with nearly the same power of the telescope aperture. As a result, the integration times required to reach confusion limits are nearly aperture-independent.

Aviary

Infrared Telescope in Space: IRTS,timized to observe the diffuse extended emission, and will survey about 10% of the sky in 20 days of mission life. The IRTS will provide significant information on cosmology, interstellar matter, late type stars, and interplanetary dust.

SOFIA: The Next Generation Airborne Observatory,here in the world. The concept is based on 20 years of experience with NASA’s Kuiper Airborne Observatory (KAO), which SOFIA would replace. SOFIA will complement the capabilities of other future space missions, and will enable scientists to make observations which would otherwise be made from space.
