Book Description
Approximately 9000 square degrees of the celestial sphere was surveyed in four infrared bands with a rocket-probe-borne telescope. This Far Infrared Sky Survey Experiment (FIRSSE) covered the galactic plane between 120 degrees and 255 degrees longitude and the Orion and Taurus Molecular Clouds. A list of almost 300 bright 90 μm sources is presented along with associated measurements at 20, 27, and 40 μm. A description is given of the conduct of the experiment, the first space-borne use of super-fluid helium under active thermal loading.

Book Description
Numerical coadding of repeated scans of an attitude-stabilized rocket-launched cryogenic telescope has achieved the theoretical gain of N in signal-to-noise ratio. The 3 December 1975 flight of the telescope also demonstrated a sensitivity improvement nearly as large, resulting from the increased effective-integration time, while retaining the higher frequency response of the detectors to discriminate in favor of point sources. Several infrared sources in a 1.2 deg by 10 deg area around beta-Andromeda were measured at 11.0 and 19.6 micrometers, including two faint red galaxies (NGC 389 and NGC 393) and a number of unidentified objects.
