  5. 5. Curiosity is exploring a hypothesis that south-tilted sandstone beds on Gale Crater’s plains indicate water-driven transport of sediment, building lower Mount Sharp from lake deposits NASA/JPL-Caltech/GSFC Possible lake deposits at the base of Mount Sharp Mount Sharp 5
  6. 6. Curiosity’s Radiation Assessment Detector measures high-energy radiation The RAD instrument measured the radiation flux from both galactic cosmic rays and solar energetic particles, in cruise and at Mars’ surface If shielded similarly to the RAD instrument, a crewed mission would receive ~1 Sievert of exposure in a round trip to Mars with 500 sols on the surface [Hassler et al., 2014] Hard Solar Event 6
