Isotopes are versions of an element with different masses. As water evaporated, light versions of carbon and oxygen were more likely to escape into the atmosphere, while the heavy versions were left behind more often, accumulating into higher abundances and, in this case, eventually being incorporated into the carbonate rocks. Scientists are interested in carbonates … Read more
During its first 10 years at Mars, MAVEN has helped to explain how the Red Planet evolved from warm and wet early on into the cold, dry world that we see today.

Tests on Earth appear to confirm how the Red Planet’s spider-shaped geologic formations are carved by carbon dioxide. Since discovering them in 2003 via images from orbiters, scientists have marveled at spider-like shapes sprawled across the southern hemisphere of Mars. No one is entirely sure how these geologic features are created. Each branched formation can … Read more
These are far-ultraviolet Hubble images of Mars near its farthest point from the Sun, called aphelion, on December 31, 2017 (top), and near its closest approach to the Sun, called perihelion, on December 19, 2016 (bottom). The atmosphere is clearly brighter and more extended when Mars is close to the Sun.Reflected sunlight from Mars at … Read more
Twelve years ago, NASA landed its six-wheeled science lab using a daring new technology that lowers the rover using a robotic jetpack. NASA’s Curiosity rover mission is celebrating a dozen years on the Red Planet, where the six-wheeled scientist continues to make big discoveries as it inches up the foothills of a Martian mountain. Just … Read more
NASA invites the media and public to explore the nexus of space and food innovation at the agency’s Deep Space Food Challenge symposium and winners’ announcement at the Nationwide and Ohio Farm Bureau 4-H Center in Columbus, Ohio, on Friday, Aug. 16. In 2019, NASA and the CSA (Canadian Space Agency) started the Deep Space Food … Read more
The six-wheeled geologist found a fascinating rock that has some indications it may have hosted microbial life billions of years ago, but further research is needed. A vein-filled rock is catching the eye of the science team of NASA’s Perseverance rover. Nicknamed “Cheyava Falls” by the team, the arrowhead-shaped rock contains fascinating traits that may … Read more
Both Shadow and Substance: The dramatic image of NASA’s Mars Exploration Rover Opportunity’s shadow was taken on sol 180 (July 26, 2004), by the rover’s front hazard-avoidance camera as the rover moved farther into Endurance Crater in the Meridiani Planum region of Mars. Source link
