Keeping with the practice of sol-by-sol discussions, here it is.

LOL The press have such short attention spans. The mission has hardly started and most of them have gone. lol

A few media outlets (worst of all, DrudgeReport) overhyped the mission with headlines like "Life on Mars?" which would naturally give the readership a hangover when they find out: that absolutely no evidence of any kind has yet been collected by the mission; that the instruments on the mission are not even capable of detecting life when they do start operating.

For those people who read headlines alone, the discovery of life on Mars is already ancient history, even though it never happened. But it will continue to "happen" every few years.

I've been wondering about that.

Are they going to vaporize all the H2O they collect to analyze it for organic compounds?

If I ran the zoo, I would definitely take a bit of ice, at least once, gently warm it to 5 degrees C or so, and turn the microscope loose on the liquid results. Long shot? Sure, but worth trying. Does anyone know these sorts of details about the science plan? and about what exactly the microsope is intended to examine? Mineral/crystal/etc. structures and (conceivably) oven-safe fossils only??

Good thing you dont run the zoo.

If you warmed the ice to 5 deg C it would boil away quickly. Even exposed ice may sublime away in minutes-hours.

The ovens in TEGA are about 3mm in dia (see http://www.lpl.arizona.edu/~rlorenz/TEGA.pdf )
so you can't get a microscope (which is an entirely different instrument elsewhere on the lander) into them
(the point is after all to seal the oven (and once you seal each one, you cant unseal it)
so you can look for water vapor, organics etc that are evolved. NB
big difference between TEGA on MPL and TEGA-II on PHX is that while the TA ovens are the same, the EGA
is very different - an absorption spectrometer for CO2 and H2O on TEGA-1, but a mass spec for TEGA-II that
might also detect organics.

But I dont think soil sampling is planned for a few sols yet.

Still another day of arm unstow yet.
