First evidence of hidden underground channels on Mars
 

One of the largest of the recently carved channel systems on Mars, once sculpted by massive floods but now smothered under ancient lavas, is more than twice as deep as previously thought. Using radar data gathered by the Mars Reconnaissance Orbiter, researchers were able to see several dozens of meters below ground level in an area (dotted box, above) including the presumed source of Marte Vallis, a chaotic system of channels (depicted in white) created less than 500 million years ago—a geologically recent era in the Red Planet’s history.
