BLAST

(Balloon-borne Large Aperture Submillimeter Telescope)
(balloon-borne 1.8m submillimeter telescope)

BLAST (for Balloon-borne Large Aperture Submillimeter Telescope) is a 1.8-meter Far Infrared (FIR) telescope that is flown in a high-altitude balloon. It has made several flights from different locations, including Antarctica, its first operational flight in 2005. Its second operational flight damaged the original 2-meter operational mirror, which was replaced by a 1.8 meter mirror.

Its instrument is an Imaging Fourier Transform Spectroscopy (IFTS), modeled after the Herschel Space Observatory SPIRE design, and the project served as a pilot for that instrument.
