The Mars Reconnaissance Orbiter is testing a series of large spacecraft rolls that will help it hunt for water. After nearly 20 years of operations, NASA’s Mars Reconnaissance Orbiter (MRO) is on a roll, performing a new maneuver to squeeze even more science out of the busy spacecraft as it circles the Red Planet. Engineers […]

NASA’s Perseverance Rover Scours Mars for Science
In addition to drilling rock core samples, the science team has been grinding its way into rocks to make sense of the scientific evidence hiding just below the surface. On June 3, NASA’s Perseverance Mars rover ground down a portion of a rock surface, blew away the resulting debris, and then went to work studying […]
NASA’s Curiosity Mars Rover Starts Unpacking Boxwork Formations
The rover recently drilled a sample from a new region with features that could reveal whether Mars’ subsurface once provided an environment suitable for life. New images from NASA’s Curiosity Mars rover show the first close-up views of a region scientists had previously observed only from orbit. The images and data being collected are already […]
A Martian Volcano in the Mist
Arsia Mons, one of the Red Planet’s largest volcanoes, peeks through a blanket of water ice clouds in this image captured by NASA’s 2001 Mars Odyssey orbiter on May 2, 2025. Odyssey used a camera called the Thermal Emission Imaging System (THEMIS) to capture this view while studying the Martian atmosphere, which appears here as […]
NASA Mars Orbiter Captures Volcano Peeking Above Morning Cloud Tops
The 2001 Odyssey spacecraft captured a first-of-its-kind look at Arsia Mons, which dwarfs Earth’s tallest volcanoes. A new panorama from NASA’s 2001 Mars Odyssey orbiter shows one of the Red Planet’s biggest volcanoes, Arsia Mons, poking through a canopy of clouds just before dawn. Arsia Mons and two other volcanoes form what is known as […]
NASA’s MAVEN Makes First Observation of Atmospheric Sputtering at Mars
After a decade of searching, NASA’s MAVEN (Mars Atmosphere Volatile Evolution) mission has, for the first time, reported a direct observation of an elusive atmospheric escape process called sputtering that could help answer longstanding questions about the history of water loss on Mars. Scientists have known for a long time, through an abundance of evidence, […]
Devil’s in Details in Selfie Taken by NASA’s Mars Perseverance Rover
The rover took the image — its fifth since landing in February 2021 — between stops investigating the Martian surface. A Martian dust devil photobombed NASA’s Perseverance Mars rover as it took a selfie on May 10 to mark its 1,500th sol (Martian day) exploring the Red Planet. At the time, the six-wheeled rover was […]
Sunset on Mars
NASA’s Mars Exploration Rover Spirit captured this stunning view as the Sun sank below the rim of Gusev crater on Mars 20 years ago. In this image, the bluish glow in the sky above the Sun would be visible to us if we were there, but an artifact of the panoramic camera’s infrared imaging capabilities […]
