Just as NASA scientists were preparing to use Curiosity's "wet chemistry" experiment for the first time, the rover's drill broke, throwing a key test for orgainics on the Red Planet into doubt.
The Columbia Hills region is one of three locations on the Red Planet — along with Jezero Crater and NE Syrtis — that have been identified as leading contenders as landing sites for NASA's next Mars rover.
A cluster of recent meteorite impacts on Mars have been found, highlighting a deadly hazard for future Mars colonists.
Eight potential locations will be studied only three or four will be prioritized for exploration by NASA's next rover mission to the Red Planet.
The mystery of how Mars could have once had water flowing on its surface has deepened — the Red Planet's early atmosphere likely possessed hundreds of times less carbon dioxide than needed to keep it warm enough for liquid water to exist.
Courtesy of the European Mars Express orbiter, a new perspective of the Red Planet's north pole provides a stunning new view of the ancient Martian ice.
Rovers have limited time on Mars, so to optimize the science returns, geologists on Earth are devising new strategies for NASA's rover drivers to find the ripest areas of study.
A new analysis of a rare Mars meteorite resets the clock for when our neighboring planet was covered with lava flows.
A new report says development on the sample return cache system for NASA's next rover mission to the Red Planet is behind schedule, possibly delaying the rover's launch.
A new study suggests periodic releases of methane from the Red Planet's surface turned its atmosphere into an efficient trap for solar radiation, letting temperatures climb high enough for liquid water to persist.
