Sounds messed up and shallow I guess but I have some time to waste so I dont mind. All im interested in is to maybe find something cool in the pictures I go through.

Funny, I just wanted to post Michael Mumma statement about findings of methane on Mars ( and for now 3 independent researchers team confirmed methane).
And I highly daubted - that methane is result of vulcanic activity ...it must be a very volcanic effect, coz sunlight destroy methane in about 300 years!!?
Ammonia is not a stable molecule in the Martian atmosphere. If it was not replenished in some way, it would only last a few hours before it vanished
Nitrogen is rare in the Martian environment but because no form of terrestrial life can exist without it, the presence of ammonia may indicate that Martian microbial life is hoarding it.
"There are no known ways for ammonia to be present in the Martian atmosphere that do not involve life," the Nasa scientist said.

The two possible sources are either active volcanoes, none of which have been found yet on Mars, or microbes.
Vittorio Formisano, principal investigator for the instrument, is expected to release details of new findings at an international conference being held next week in Paris. Although Mars Express has been in orbit around Mars since December 2003, scientists have so far only analyzed a fraction of the data.
The detection of ammonia comes just a few months after methane was found in the Martian atmosphere. Methane is another gas hinting strongly of a biological origin

Than we are left - with biological origin of that gas, living microbes.
Methane on Mars may be produced at rates 3000 times higher than previously thought and partially destroyed by dust storms, controversial new research suggests.

The last of the 27th release is called "Candidate Cavern Entrance Northeast of Arsia Mons", but I think someone in here may find it a different thing.
You can see it here.
And here you can see a close-up with a enhancement of the "cavern entrance".

The HiRISE camera is very sensitive and we can see details in almost any shadow on Mars, but not here.............The range to the target site was 252.5 km (157.8 miles). At this distance the image scale is 25.3 cm/pixel (with 1 x 1 binning) so objects ~76 cm across are resolved.

I have so many references to Methane from official pages that i hardly know what to do with them. I love how every reference contains that interesting bits of other information that one can compare to notice just how significant it in fact is.
As i understand that is their estimation for how fast methane is destroyed in the Martian atmosphere but since they have now detected ammonia ( which as i recall basically breaks down from Methane due to solar activity) the game is pretty much up as one can tell from statements such as the following.
