Science Interest Group
X-Ray
The X-Ray Science Interest Group (XR SIG) serves as an active communication forum for X-Ray astrophysics. XR SIG is open to the scientific community.
About XR SIG
Supporting Mission Studies and Concept Development for Future X-Ray Observatories
The X-Ray Science Interest Group (XR SIG) will provide quantitative metrics and assessments to NASA with regard to future X-Ray observatories.
XR SIG will track and analyze evolving science goals and requirements in X-Ray astronomy, especially as current hot topics evolve. XR SIG will also analyze technology development and prioritization plans and assist the Physics of the Cosmos Program Analysis Group in determining technology needs.
