Radiation chat.

Chris, any characterization of what this level of radiation would mean for an astronaut on Mars ???...probablly too early to comment...

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.

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. :D

I was going to suggest the same :)

The SkyCrane "crater".

This mission has seemingly moved on to the "it's a rock" phase.

Leo just asked that question!

Answer is it's complex and one of the more interesting questions. RAD will help design the shielding for HSF Mars missions.

More notes that this landscape looks a lot like Earth, "it feels comfortable"

One thing I've noticed from these early pictures is that the rover's wheels did not seem to sink into the surface at all...implies to me that the surface where MSL landed is quite hard....no dunes in sight a la MERs

The ballast impacts are far away (and across a dune field they don't want to cross). So unlikely to check out those new holes.

Sounds like the ballast impacts will not be investigated- would have to traverse the dune field, and travel across areas where the stratigraphy is obscured.

And the answer is 0517:57 UTC SCET, so the value we thought we heard on the SOL 0 thread (0514:39) was something else.
This is much more consistent with the expected timeline.

So there will be that animation of landing in hi res in a day or so I believe!

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.

Answer is it's complex and one of the more interesting questions. 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.

Given finite cash, if we want to go to Mars then we should go to Mars.

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......

I'd have to listen to it again.
They said something was 1014:39 but maybe it wasn't rover touchdown
or maybe it wasn't PDT but some uncorrected telemetry counter value?

I'd be cautious crossing anything off the list if all we have is less than a week's worth of uncalibrated data.

Yes. Wait for publication in a peer-reviewed journal.
