Radiation chat.
Heh. Hat tip to conspiracy theorists! Saying people might think NASA is pulling a fast one and that they put a rover out in the mojave desert.

Bedrock is pretty high up to be the floor of the crater. Guess is that it is a "rock" that formed some time after the crater. Do not know how hard the rock is, so rock in quotation marks.

RAD will help design the shielding for HSF Mars missions.

RAD will help design the shielding for HSF Mars missions.Looking at the graph though average radiation looks about half that of cruise- which is at least what one would expect from having a planet blocking half of the sky. Those peaks show that shielding of some kind is likely still required.
It wasn't heard wrong, that's what they said the other day (14:39). They have finally corrected it after being asked to, but not explained why they had it wrong.
So can we now cross off "unreasonable" radation levels on Mars for humans off the Mars Risk list ...I believe that was one of the major unknowns......
