The Balloon-borne Large Aperture Submillimeter Telescope for Polarimetry (BLASTPol) is a suborbital mapping experiment designed to study the role played by magnetic fields in the star formation process. BLASTPol uses a total power instrument and an achromatic half-wave plate to modulate the polarization signal. During its first flight from Antarctica in December 2010, BLASTPol made degree scale maps of linearly polarized dust emission from molecular clouds in three wavebands centered at 250, 350, and 500 mu m. This unprecedented dataset in terms of sky coverage, with sub-arcminute resolution, allows BLASTPol to trace magnetic fields in star-forming regions at scales ranging from cores to entire molecular cloud complexes. A second long-duration flight is scheduled for December 2012.
