The balloon-borne Gamma-Ray Imager/Polarimeter for Solar flares (GRIPS) instrument will provide a near-optimal combination of high-resolution imaging, spectroscopy, and polarimetry of solar-flare gamma-ray/hard X-ray emissions from ~20 keV to >~10 MeV. GRIPS launched on January 19, 2016, for a long-duration flight over Antarctica at an altitude of up to 130,000 feet.  Learn more about the science, the team, and the instrument.  Also, you can follow the project on Twitter!
