A New Explanation for Organics on a Mars Rock That Fell to Earth
Organic molecules on a Martian meteorite have fueled nearly 30 years of scientific debate. New evidence suggests they were formed by Martian processes, offering more support for a once habitable environment on the Red Planet.
Scientists Turn Back Time to Track Methane Emissions on Mars
Period spikes of methane on Mars could originate inside Gale crater, where NASA’s Curiosity rover is currently exploring.s
Machine Learning Algorithms Help Scientists Explore Mars
Researchers applied machine learning algorithms to several distinct chemical compositions of Mars and suggest that these algorithms could be a powerful tool to map the planet’s surface on a large scale.
Planetary Dunes Tell of Otherworldly Winds
On Earth and throughout our solar system, ripples and dunes in sand and dust offer insights into how winds blow, liquid currents flow, and solid particles fly and bounce over the terrain.
NASA Prepares Its Artemis Gateway to Orbit the Moon
Throughout its anticipated 15-year tour of duty, the Gateway will serve as a station for astronauts and lunar landers—and enable new scientific discovery.
Scientists Plan a Home Away from Home for Mars Samples
The core tubes being collected by the Perseverance rover won’t arrive for years, but NASA and the European Space Agency are outlining needs for a facility to assess their safety and store and distribute them.

A Simple Recipe for Making the First Continental Crust
Laboratory experiments serendipitously revealed a rock-forming process that might explain how the first continental crust formed on Earth—and possibly on Mars.
Summer Could Be Earthquake Season on Mars
InSight data hint that shifting carbon dioxide ice loads, illumination changes, or solar tides could drive an uptick in marsquakes during northern summer—a “marsquake season.”
