Current state-of-the-art instrumentation being sent to Mars to collect and analyze evidence of ancient life on the red planet may not be sensitive enough to make accurate assessments, according to an ...
The ongoing search for signs of life on Mars relies in part on terrestrial analogs – places on Earth closely resembling the past or current geology and climate of the red planet that can be readily ex...
The eerie sound of an extraterrestrial whirlwind has reached the Earth from more than 50 million miles away, thanks to the first working microphone to traverse the surface of Mars. The audio records t...
If experiments done in small bottles in a University of Oregon lab are accurate, the friction of colliding Martian dust particles is unlikely to generate big electrical storms or threaten newly arrive...
Multi-temporal Earth Observation and Mars orbital imagery data with frequent repeat coverage provide great capability for planetary surface change detection. When comparing two images taken at differe...
Quantitative analysis of hydrated minerals from hyperspectral remote sensing data is fundamental for understanding Martian geologic process. Because of the difficulties for selecting endmembers from h...
Geochemical studies of shergottites (Martian basalts) based on Rb-Sr, Sm-Nd, and Lu-Hf isotopic systematics have provided clues to understanding the geochemical evolution of the Martian mantle and id...
Dramatic climate cycles on early Mars, triggered by buildup of greenhouse gases, may be the key to understanding how liquid water left its mark on the planet's surface, according to a team of planetar...
The Sixth International Conference on Mars Polar Science and Exploration will be held September 5–9, 2016, at the University of Iceland in Reykjavik, Iceland. Reykjavik was chosen as the site of the s...

Remote sensing data from orbiter missions have proposed that ground ice may currently exist on Mars, although the volume is still uncertain. Recent analyses of Martian meteorites have suggested that ...
We have identified two classes of crater clusters on Mars. One class is “small clusters” (crater diameter D ~ tens m, spread over few hundred m), fitting our earlier calculations for the breakup of we...
While new evidence suggests that Mars may harbor a tiny amount of liquid water, it exists today as a largely cold and arid planet. Three billion years ago, however, the situation may have been much di...
The extensive valley networks on the surface of Mars were probably created by running water billions of years ago, but the source of that water is unknown. Now, a team of Penn State and NASA researche...
Lujendra Ojha, the Georgia Tech Ph.D. candidate who led the study, first noticed these puzzling features in High Resolution Imagine Science Experiment (HiRISE) images returned by the MRO spacecraft as...
