COSI
(2000s balloon-based gamma ray telescope)
COSI (for Compton Spectrometer and Imager, formerly
NCT for Nuclear Compton Telescope) that has made several
flights since 2005. It has science goals, including
GRB polarimetry, but also serves as a pilot
for technologies that will be used in future space-based
gamma-ray observatories.
