The goals of the Cosmic Ray Science Interest Group (CR SIG) are to provide quantitative metrics and assessments to NASA in regard to current and future needs of the cosmic-ray astrophysics community and to act as a focal point and forum for the cosmic ray community.

CR SIG will work towards producing a white paper covering:

  • the major open science questions
  • a brief survey of the current and planned, US and International, space and ground-based projects — their energy coverage (from about 108 eV to 102 eV), sky coverage, and particle type coverage (electrons, positrons, nucleons, anti-nucleons, nuclei, anti-nuclei, neutrinos, and new particles)
  • a survey of the state-of-the-art capabilities, the next generation technology needs, and potential science return from new technologies and capabilities
  • a vision for the future of cosmic ray science in space

The CR SIG is open to all members of the community.
