Raging Winds On Mars
Despite the very thin Martian atmosphere, there are also winds on Mars that are central to the climate and the distribution of dust.
Did Mars Once Have an Ocean? New Research Suggests Yes
Billions of years ago, water flowed across Mars. Most scientists agree the red planet had rivers. But did those rivers flow into an ocean? New research from the University of […]
Reconstructing Jezero Crater’s Paleoenvironment: Insights from Perseverance Rover and Orbital Data
Jezero Crater on Mars is a critical site for investigating ancient aqueous environments due to its preserved delta and lacustrine features.
ExoMars Rosalind Franklin Mars Rover Sample Processing
The Rosalind Franklin rover’s drill has a maximum reach of two metres – deeper than any other mission has ever attempted on the Red Planet. This depth allows access to […]
Born Dry or Born Wet? A Palette of Water Growth Histories in TRAPPIST-1 Analogs and Compact Planetary Systems
It is still unclear whether exoplanets in compact multiplanet systems such as TRAPPIST-1 are able to accrete large quantities of volatiles, grow to sufficient mass, and maintain robust atmospheres and […]
Multiple Episodes of Fluid Alteration in Jezero Crater Indicated by MIST Mineral Identifications in PIXL XRF Data
The Mineral Identification by Stoichiometry (MIST) algorithm can identify mineral species in geochemical data sets. MIST is applied to X-ray fluorescence chemical analyses from the Planetary Instrument for X-ray Lithochemistry […]
Away Team Training: Analogs for VENus’ GEologically Recent Surfaces (AVENGERS) Initiative
Editor’s note: when it comes to conducting field trips – sorties – Away Team missions – on another world, astrogeology and astrobiology and astrochemistry overlap with one another all the […]
The Biology, Microclimate, and Geology of a Distinctive Ecosystem Within the Sandstone of Hyper-Arid Timna Valley, Israel
Microbial endolithic communities in the sandstone rocks of the southern Negev Desert, particularly in Timna Park, were initially discovered by Imre Friedmann and Roseli Ocampo-Friedmann in their pioneering study about […]
Super Fungi Survive Extreme Mars-like Environments
People have long been intrigued by the possibility of life beyond Earth and how it might endure in extraterrestrial environments. There is no confirmed evidence of extraterrestrial life, not even […]
