(Suborbital Polarimeter for Inflation Dust and the Epoch of Reionization)
(2015 airborne observatory to observe CMB polarization)

SPIDER (SPIDER is the official name, but previously was considered an acronym for Suborbital Polarimeter for Inflation Dust and the Epoch Of Reionization) is a balloon-borne observatory with six 26-cm aperture microwave, cryogenically-cooled refracting telescopes, each dedicated to a polarimeter with TES sensors. It is part of the effort to find large-scale patterns (primordial B-modes) in CMB polarization. SPIDER flew its initial mission over Antarctica in January 2015, successfully yielding data, though damaged on landing, not unusual for such balloon-based missions (but still far less expensive than equivalent space-based observatories). Plans were announced for another flight covering more frequencies, but I've found no recent references.
