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.

Meanwhile, we visited NOAA's ARO facility here at Pole and collected our own samples of the clearest air on Earth.… twitter.com/i/web/status/811115947666894848
The ole @GRIPSballoon luck, with regards to the weather, is back. Still waiting at Pole for good weather to fly out to the GRIPS site.
Congrats to the BACCUS, ANITA IV and STO-2 balloon teams who have all launched this season from LDB McMurdo. t.co/yZu62bNCS6
The Twin Otter plane arrived at South Pole a few of days ago. We are waiting on good weather for our reconnoissance flight to @GRIPSballoon
It's been great to get to know our extended groom and mountaineering team while we wait out the weather delays @GRIPSballoon
The @GRIPSballoon team is currently waiting for a Twin Otter plane to arrive at South Pole before we can get out on a reconnoissance flight.
Last year, NASA set a record for latest Antarctic balloon launch (@GRIPSballoon); this year, the earliest. The clim… twitter.com/i/web/status/803544205188599808
@NDuncanSolar and I are on the ice. We're going through field safety training before heading out to recover .@GRIPSballoon
The .@GRIPSballoon is at the Amundsen-Scott South Pole Station safe and sound!
We've spent that last few days preparing for the .@GRIPSballoon recovery in McMurdo, sending cargo to Pole for stage 2.
The .@GRIPSballoon team survived happy camper training out on the Ross Ice Shelf. It was actually too hot in our tents.
Getting ready for Deep Field Shakedown training. A mini field camp training out on the Ross ice shelf before we really go into the field.

Congrats @Calidarien @hazbain @NDuncanSolar and NASA/Berkeley team on successful @GRIPSballoon launch in Antarctic! twitter.com/antarcticreport/status/689267875748556800
Thank you everyone who has supported us throughout the project, at home, here in Antarctica and today's launch! We very much appreciate it!!
