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.
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.
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.
The minerals identified by the Mars Reconnaissance Orbiter provide more evidence that the planet may have once been habitable.
A bombardment of the Red Planet 4 billion years ago could have created hot springs that allowed life to flourish.
