A new theoretical model suggests that ancient floods that carved canyons on Earth and Mars may have been much smaller but lasted longer than previously thought.
The discovery of dense concentrations of recurring flowlike features in two Valles Marineris chasms could aid in the search for life and influence future exploration of the Red Planet.
Landing robotics distinguish the craft from past models, allowing researchers to target smaller flat areas that are surrounded by rock.
Temperature readings acquired from orbit show that Mars's surface gets cold enough at night to allow layers of solid carbon dioxide frost up to several hundred micrometers thick to build up near the equator.
New computer simulations of Martian dust devils could aid Red Planet weather forecasts.
The rover's neutron spectroscopy instrument hints at an unexpected trend: The upper soil levels in the layers of Gale Crater's Kimberley formation seem to hold more water-associated hydrogen.
NASA's first Mars program director advised the creators of the new film The Space Between Us, which opens this summer, on the science related to Mars colonization.
The Public Lecture at AGU's 2016 Fall Meeting will feature three experts—including one still in high school—to discuss landing site selection for the Mars 2020 rover.
NASA's latest mission to Mars has uncovered the origins of fast-moving streams of particles high above the planet, flowing against the solar wind.
Massive meteorites likely slammed into a Martian ocean billions of years ago, unleashing tsunami waves up to 120 meters tall, a close study of a region of the Red Planet's terrain has found.
