The brave little rover has been stuck in the sand for a year and a half, spinning her wheels and wiggling her robot arm futilely. As she's kicked up sand, though, she has uncovered deeper layers of Martian soil, and analysis of the difference between the surface and what lies beneath shows evidence of water.
Spirit is still stuck in the sand, and Opportunity's future beyond Mars' next solstice is unclear, but the Mars Reconnaissance Orbiter continues to beam back groundbreaking images from high above the Red Planet. Using images taken from NASA's MRO, researchers at Imperial and University Colleges London have determined that water-filled lakes existed on the Martian surface 800 million years later than previously thought.

Just because NASA has two robots on the surface right now doesn't mean the landing of the Phoenix probe is a sure thing. At a news conference yesterday, NASA officials stressed that landing a spacecraft on Mars isn't easy: 55 percent of all attempts to do so have failed. Not to mention that the technique Phoenix will use to do so hasn't been employed in a while.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
