Returning to NASA's Mars Exploration Rover for the first time in weeks, one can take for granted dozens of new photographs and discoveries because of Spirit's and Opportunity's solid construction — the rovers now having outlived their factory specifications by nearly sixfold. Venerable or not, the rovers' ability to chew gum and walk at the same time is something mission commanders are happy to show off. Spirit's patient observation of dust devils has paid off with a short film of one of the wind phenomena. The rover has also been rummaging about a nearby rock outcropping. Opportunity, while struggling for purchase on a dune, has been stargazing and captured the above image of our planet in Martian twilight; reminding us that two bodies as astronomically close as Earth and Mars are, for our metric, very small and very far from one another.
