Lot of MER chatter that doesn't appear in the press releases. Some MSL landing site chatter.

Beware of the link to this report from the main page. It links to a truncated version that doesn't have an explanation of the truncation, nor a link to the rest of the doc (no "next page" or "page 1 of n"). There is a link to a "printer friendly" HTML version that displays the whole report (my link above goes there). I'd be pissed if I was Bruce.

Some random stuff:

But Squyres added that, after the first tentative detection of this mineral, the team had decided to confirm it by tuning the spectrometer to the specific frequency band used to measure jarosite and then leaving it running for fully 24 hours. In the process they not only solidly confirmed the jarosite, but found that the etched rock contains not a trace of pyroxene and olivine -- two minerals found in huge amounts in the basalt lava rock which covers most of Mars. So, if the etched rock started out as basalt or volcanic ash, it has been very massively altered indeed by water.

About an upcoming experiment at Rio Tinto:
(MARTE's procedures also serve as a technique to develop ways of extracting and analyzing such samples without contaminating them -- thus serving as a useful procedure to rehearse similar future biological drilling operations on Mars. In fact, next year another project will actually set up a simulated Mars lander at the site to drill automatically deep into the ground and analyze the samples it extracts without direct intervention by human engineers or scientists.)
