The Balloon-borne Large Aperture Submillimeter Telescope (BLAST) is a
INAOE, and Cardiff University. The third flight of BLAST in Antarctica
was a scientific success, but much of telescope was destroyed after landing. It has been rebuilt for a flight from Antarctica in the 2010-11 austral summer. This most recent flight of BLAST (aka BLAST-Pol) has a polarimeter to observe the polarized light from star forming cores. The light is polarized due to magnetic fields. It is thought that the magnetic fields inhibit the collapse of the cores. The Herschel Space Observatory does not have a polarimeter.
BLAST's primary science goals are:[1]
- Measure photometric starburst galaxies, thereby constraining the evolutionary history of those galaxies that produce the FIR/submillimeter background.
- Measure cold pre-stellar sources associated with the earliest stages of planet formation.
- Make high-resolution maps of diffuse galactic emission over a wide range of galactic latitudes.

Flights
- BLAST's first flight was an engineering (test) flight. BLAST launched at approximately 15:10 UTC September 28, 2003 from the Columbia Scientific Balloon Facility base in Fort Sumner, New Mexico, and landed approximately 26 hours later near Newcomb, New Mexico.
- BLAST's second flight was its first scientific flight. BLAST launched at 1:10 UTC June 12, 2005 from Victoria Island, Northwest Territories, Canada.
- BLAST's third flight was its second scientific flight. BLAST launched at 1:54:10 UTC December 21, 2006 from McMurdo Station, Antarctica and landed at 1:05 UTC January 2, 2007 756 km southwest of McMurdo. The telescope's third landing was disastrous; the parachute failed to release itself from the gondola (upon landing) and the Antarctic winds dragged it along the surface of the ice for 24 hours, with it finally coming to rest in a crevasse 200 km from the landing site. The hard drives containing the data it had collected were eventually located and recovered from the drag path, but the telescope was mostly destroyed.[4]
- BLAST's fourth flight (the first as BLAST-Pol) launched at 4:06 UTC December 27, 2010 from Willy Field, McMurdo Station, Antarctica and landed on the Ross Ice Shelf.
