Depending on what NASA's "Major" finding's that they plan to announce, and the final science results from the phoenix mission, Im wondering if Vastitas Borealis could be added to the allready 6 final landing sites for MSL?. Phoenix's landing site looks sofar VERY science rich, and worthy for exploration for another mission pancam.gif wheel.gif wheel.gif wheel.gif .

I believe that anything that far north would violate the minimum temperature limits.

True, though the limits are not entirely based on temperature. All sites must be within 45 degrees of the equator and meet other constraints. See http://webgis.wr.usgs.gov/msl/Engineering.htm

Mike, could you go into more detail about the lat limitations? Only thing I can think of besides temp is relay satellite availability, and that's far from guaranteed during the mission timeline; it's a somewhat puzzling constraint.

It's mostly to do with total energy for heating of things that aren't warmed by the RTG waste heat. There are also DTE and relay geometry constraints. The site I linked to has details (in the PDF document http://webgis.wr.usgs.gov/msl/docs/MSL_Eng...uide_v4.5.1.pdf .)

For DTE, how far above or below the horizon at the phoenix landing site would earth be?.

PHX doesn't do DTE smile.gif But Earth on Sol 69 is moving from 4.7 degrees above the Northern horizon at 10pm local, to 47.8 degrees above the Southern Horizon at 10AM local

I was saying DTE for MSL hypothetically if MSL were to land at the phoenix landing site smile.gif .

WOW - more funky flight hardware!!

I hope when it's all shipped to KSC, it's still in pieces. Watching that final ATLO stuff via KSC webcams was fantastic... Phoenix didn't really have much of that. Of course, what I hope more, is that it all comes together well, and on time biggrin.gif

That thing does NOT look stable.

I found this article about The Potential MSL Site: Miyamoto Crater
It explains a lot about the geology of the site and the pluses and minuses of the site.

The article is dated September 16, 2008 and was put out by
The Martian Chronicles

Looks like reactions weren't all the same... rolleyes.gif

"After the vote is revealed, there is some discussion of whether things were fair: (Diana Blaney: Is there a bimodal distribution related to who is in the room -- basically the 'spectroscopy' sites have sunk to the middle from comparatively favored position at early landing sites...Steve Ruff: Why did the vote go on the questions tailored in this way? A pure ranking would have been better)."

"A bunch of people are bummed out by the results (quite openly), but some are happy (less openly)."

Here.
