A toxic chemical in Martian dirt may obscure scientists' search for extraterrestrial life. Perchlorates on the Red Planet may cause reactions in Curiosity's soil samples that destroy organic compounds, researchers say.
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.
24 September 2013, 06:02 PM ET
The 1-ton Curiosity rover paused to examine a few rocks late last week, making the first of five planned science stops en route to the 3.4-mile-high Mount Sharp. The break was fruitful, returning further signs of long-ago flowing water.
20 September 2013, 11:23 AM ET
The Mars Science Laboratory's navigation technology allows controllers to simply determine a destination and let the rover figure out how to drive there. The software searches for obstacles and holes, then safely avoids them.
11 September 2013, 11:27 AM ET
TextureCam, a technology whose development is led by NASA's Jet Propulsion Laboratory, is designed to take pictures of rocks in 3-D and prioritize the ones that are most scientifically interesting. The smart camera could be used on Mars or more distant lo
