Mars has water trapped in the polar ice caps. More water may lie just beneath the surface.
26 September 2013, 05:01 PM ET
Water on Mars has long been sought after by researchers.
26 September 2013, 02:01 PM ET
Future Mars explorers should be able to get all the water they need out of the red dirt beneath their boots, a new study suggests. NASA's Mars rover Curiosity has found that surface soil on the Red Planet contains about 2 percent water by weight.

Small, serpentine robots could help Mars rovers collect soil samples from crevices beneath rocks and other hard-to-reach places, and they could pull their wheeled siblings to safety if the bigger vehicles get bogged down in soft sand.

NASA's Mars rover Curiosity has revealed no trace of methane, a potential sign of primitive life, on the Martian surface, despite past observations of the gas by spacecraft orbiting the Red Planet and from Earth, researchers say.
