Andrew Wyeth's final sleep

I was actually introduced to this artist via social media (StumbleUpon), by the knowledgeable Mr. Greene. I really enjoy Wyeth's work. For real.

High methane concentrations (reds and yellows) appear during martian summer in localized plumes.


Methane does not necessarily mean life. It could rather be a false alarm.

Mars

We have lots and lots of outstanding images, (with a dash of 'photoshopping') of Mars. This here, published on Discovery Space, is one of my favorites.

With Global Navigation Satellite System GNSS (or GPS if you like) and some other techno stuff.
