    Radiation Assessment Detector (RAD)

    The Radiation Assessment Detector (RAD) will be part of a suite of instruments onboard the Mars Science Laboratory (a Mars rover scheduled to launch in 2009 intended to study the habitability of Mars). The RAD is designed to be one of the first instruments sent to Mars specifically to prepare for future human exploration. Smaller than a milk carton in size, RAD would measure and identify all high-energy radiation on the Martian surface, such as protons, energetic ions of various elements, neutrons, and gamma rays. That includes not only direct radiation from space, but also secondary radiation produced by the interaction of space radiation with the Martian atmosphere and surface rocks and soils.

    SIREST V1.0

    Space Ionizing Radiation Environments and Shielding Tools (SIREST V1.0) Site can be used to evaluate mission requirements against radiation effects from the space environment.

    Space Radiation Analysis Group (SRAG)

    The Space Radiation Analysis Group (SRAG) operates out of HEFD at JSC and provides products and services to ensure radiation exposures received by astronauts remain below established action levels and limits, conform to the ALARA principle, and comply with federal law. SRAG provides preflight training to crew members and flight controllers, analyses of both natural and man-made radiation sources, inflight radiation monitoring and exposure analysis support, and postflight dosimetry report. In the conduct of their responsibilities, SRAG interacts with the SRHP to keep abreast of research results, promising technologies and techniques, risk assessments and countermeasures.

    The Space Radiation Shielding Project, MSFC

    The Space Radiation Shielding Project is part of Space Radiation Health Research, a new research initiative sponsored by the Exploration Systems Mission Directorate at NASA Headquarters.
