IMPLICATIONS OF THE SEPTEMBER 2017 SOLAR PARTICLE EVENT FORHUMAN EXPLORATION OF MARS
2018
Although the Sun is approaching solar minimum, a series of large solar particle events (SPEs)
occurred in September 2017 that impacted both Earth and Mars. In particular, the event of 10
September 2017 was the largest event that RAD has seen on the surface of Mars since it landed
in 2012. Due to the modulating effect of the Martian atmosphere, the shape and intensity of
these SEP spectra will differ significantly between interplanetary space and the Martian surface.
Understanding how these SEP events influence the surface radiation field is crucial to assessing
associated health risks for potential human missions to Mars. We will discuss in this talk the
dosimetric quantities measured by MSL RAD before, during and after the Sept. 10 event, and
their implications for potential human missions to Mars.
MSL RAD is supported by NASA (HEOMD) under JPL subcontract 1273039 to SwRI, and by
DLR in Germany under contract with Christian-Albrechts-Universitat (CAU).
