http://marsweather.com ADMIN: Link fixed
There seems to be a new website in preparation for the weather reports. But at there and the old site http://cab.inta-csic.es/rems/marsweather.html which is up to Sol 22 now, I notice there is no entry for the humidity. The humidity sensor is on Boom 2, the damaged boom. Does that mean the humidity sensor is non-operational? (Although that was not mentioned at the press conference where the damage was discussed.) |

I setup a MSL Route Map thread to keep record of Curiosity path during the mission.
Some basic rules are on the first post but here too, just in case. (Phil, I "stole" your yesterday post here for that purpose. Hope you don't mind ) Thread created for posting MSL route maps and map updates. Comments / suggestions adding value to the route maps are allowed, but discussions regarding the route itself and "future" paths are not. Use the currently active thread for the latter. |

The humidity data must be missing for that reason (though according to the bbc which is where I got the news first they implied it was wind sensors only that might suffer a glitch.) Whether or not they can recover the data is up to there engineering wizards. -------------------- |

I had the impression that the wind sensors were more fragile than the humidity sensor. http://cab.inta-csic.es/rems/rems_instrument.html I don't know, but I'd be surprised if the humidity sensor was damaged. -------------------- Disclaimer: This post is based on public information only.

All is explained. The Vaisala data sheet indicates that the probe measures relative humidity so this is probably no more than an descriptive error on the weather page. Sounds good, though trying to specify an average relative humidity during the day with such large temperature swings becomes difficult to interpret. If we assume the specific humidity is approximately constant, then the saturation vapor pressure during the day would vary by orders of magnitude, as would the relative humidity. It is impressive though the range of temperatures the probe can measure RH at: http://cab.inta-csic.es/rems/rems_RHS_en.html -------------------- Steve [ my home page and planetary maps page ]

Moved several posts related to the Descent Stage and debris to the MSL EDL Hardware thread.

QUOTE (jmknapp) Finally found my red-blue glasses to check out some of the nice anaglyphs created by members here. Nice effects. Now I just wish there was a way to search for them by an "anaglyph" tag or some such. Or maybe a gallery page. Quick follow up to a very old post- You can search for anaglyphs- 1) click "search" in the top dark-grey bar 2) select the forum you wish to search 3) click 'More Options' 4) bottom left, select "show results as posts" 5) click 'Perform the Search' button You'll get a list, with thumbnails of posts which include the term 'anaglyph', makes it easy to scroll through. |
