QUOTE (Eyesonmars @ Nov 16 2012, 02:59 PM)  ... relative humidity is always 100% at sunrise .... Not sure why it would necessarily be 100% at sunrise unless there was overnight frost, which so far has not been reported. But the intent of my question related to whether any results were reported at the telecon for the humidity sensor. (None have been posted on the weather site.) An earlier post on this blog drew assurances that the sensor was not damaged, even though it is on the damaged boom. Did no one ask about it at the telecon? Is it still being commissioned? |

QUOTE (serpens @ Nov 16 2012, 02:49 PM) does anyone know if there is any residual magnetic field loop in the vicinity of Gale that would provide a localised magnetosphere effect? I think even the strongest remnant fields are so weak (~30 nT as opposed to Earth's field of ~30,000 to 60,000 nT) as to have little effect. -------------------- Disclaimer: This post is based on public information only.

On a somewhat related noted, it was mentioned here http://astrogeology.usgs.gov/news/item/sol...ueezing-more-in that they planned early morning chemcam observations to look for frost. |

Re radiation. they said Mars and the thin atmosphere does block some radiation. But different heavier particles are created with the atmosphere interaction which are as or more dangerous than the cruise radiation. Over all it seems that a trip to Mars and back would be the lifetime limit for an astronaut. But if you've gone to Mars and back I'd think you'd be wanting to spend a lot of time on Earth, lol.

It is interesting that it will be better as protection against radiation: residual magnetization or thicker layer of the atmosphere in lowlands, for example in Hellas.

Very weak indeed, but wouldn't this, combined with the solar wind induced magnetosphere boundary provide for a large part of the observed RAD attenuation? |

I think the column density of the atmosphere is a much more significant effect. At least that's the only one we looked at when we did our radiation analyses for the electronics. -------------------- Disclaimer: This post is based on public information only.
