Science Interest Group
Gamma Ray
The Gamma Ray SIG serves as a focal point and forum for the hard X-ray and gamma ray communities. GR SIG is open to the scientific community.
About GR SIG
Assessing Current and Future Needs for the Study of Gamma Ray Science
The Gamma Ray Science Interest Group (GR SIG) will provide quantitative metrics and assessments to NASA with regard to current and future needs of hard x-ray and gamma-ray astrophysics community.
The GR SIG will organize meetings and telecons to discuss recent science results, and current and future missions. GR SIG will also maintain a list of technology needs for future hard x-ray and gamma-ray missions, and will present suggestions to help support the specific needs of this unique community: organizational, scientific, funding.
