We’ve all seen the commercials for the Energizer Bunny, which keeps going and going and going… it just never seems to stop. This makes for an interesting analogy with the Opportunity rover, which is just now passing its 12th anniversary on Mars. Not just 90 days, as hoped for, but 12 years and counting. Incredible.

Martian sunsets look bluish due to the light scattering effects of reddish dust in the atmosphere. The other image, from Opportunity, is of the scenic Lindbergh rock mound in the Spirit of St. Louis crater, on the rim of the huge Endeavour crater. A natural monument!

There is another little Martian mystery that has people talking this week – the odd appearance a few days ago of a small rock a …
