Image of the Day: Great Blue Sand Dunes of Mars

  Blue-Crator-thumb-600x450-115713

This is image of the Red Planet, snapped by NASA's Mars Reconnaissance Orbiter shows blue sand dunes covering part of the Rabe crater, a 100-kilometre-diameter impact site in the planet's southern highlands. The dunes are an accumulation of basalt sands from the crater's floor, sculpted by Martian winds. This granular image reveals the thumbprint-like texture of the ridges, troughs and ripples formed there.

Don't be steppin' on mah Blue Sand Dunes.

Perhaps life used to flourish on the Great Blue Sands of Mars with it's blue crystal clear rivers running smoothly by and between the towering volcanoes and hulking canyons...
