The Mars Science Laboratory (MSL) Radiation Assessment Detector (RAD) — •Robert F. Wimmer-Schweingruber1, Stephan Boettcher1, Soenke Burmeister1, Cesar Martin1, Guenther Reitz2, Don Hassler3, Arik Posner3, and and the RAD Team1,2,3 — 1IEAP, University of Kiel, Leibnizstr. 11, 24098 Kiel, Germany — 2DLR Cologne — 3Southwest Research Institute
NASAs Mars Science Laboratory mission will explore and quantitatively assess a local region on the Mars surface as a potential habitat for life, past or present. Its top-level science goals are to a) Asses the biological potential of at least one target environment b) characterize the geology and geochemistry of the landing region at all appropriate scales c) Investigate planetary processes of relevance to past habitability including the role of water d) Characterize the broad spectrum of surface radiation, including the galactic cosmic radiation, solar proton events, and secondary neutrons.
The Radiation Assessment Detector RAD will 1) measure energetic charged particles (Z = 1 - 26) with energies up to 100 MeV/nucleon 2) measure neutral particles (neutrons and gammas) with energies up to 100 MeV 3) measure energetic electrons with energies up to 10 MeV 4) measure dose and LET spectra on the Martian surface 5) distinguish between major particles species 6) measure at a time resolution sufficient to resolve spectra associated with solar particle events.
We will present the current status of MSL/RAD, design and first test and calibration results.
