The first one has sent a recent image of a spooky anomaly, first observed in 1976 by Viking, called the Mars Face.

NASA's robotic missions on Mars have sent home some new and intriguing video footage of weird phenomena happening on the red planet's surface.Īlthough Mars Global Surveyor robotic probe has stopped emitting and it's now officially considered "missing in action", with the causes of its disabling remaining unknown (officially it's been caused by incorrect commands that caused the battery to overheat), there are still some tools left that permit astronomers and NASA officials to receive images from the surface: Mars Reconnaissance Orbiter, an orbiting satellite, the Spirit rover, on the surface, as well as the Mars Phoenix mission, that's due for launch in August.
