One of the three science instruments aboard the 2001 Mars Odyssey spacecraft is the Martian Radiation Environment Experiment, MARIE. The experiment consists of a stack of silicon detectors, augmented by a Cerenkov detector. MARIE is designed to measure a portion of the particle spectrum of the Galactic Cosmic Rays (GCR), as well as the high fluxes of low-energy protons (energies less than about 100 MeV) that are intermittently produced by active regions on the sun in Solar Particle Events (SPE). MARIE is providing the first detailed information about the radiation environment near Mars. The silicon detectors record the ionization energy loss of incident particles. For the particle energies measured by MARIE, the energy depositions in silicon are, to a good approximation, proportional to radiation dose in tissue. Thus pulse-height data from the silicon detectors provide a reliable measurement of the dose. Preliminary comparisons with the HZETRN model of the GCR show good agreement during solar quiet times, although more work is needed to adjust the model for some of the limitations of the detector. Also, several solar particle events of considerable interest have been observed. Detailed comparisons of these events as seen at Mars and as seen by near-Earth detectors such as GOES-8 provide information about the CME-driven shockwaves that accelerate the particles.
