This paper reviews the phosphate phases in meteorites and those measured by landed spacecraft, what they reveal about past igneous and aqueous conditions on Mars, and important implications for potential […]
NASA’s Curiosity rover, currently exploring Gale Crater on Mars, is providing new details about how the ancient Martian climate went from potentially suitable for life — with evidence for widespread […]
In a new study appearing today in the journal AGU Advances, scientists at MIT and NASA report that seven rock samples collected along the “fan front” of Mars’ Jezero Crater […]
Early diagenetic nodules with low permeable and weather-resistant structures are considered to be favorable for biosignature preservation.
The question of whether Mars ever supported life has captivated the imagination of scientists and the public for decades. Central to the discovery is gaining insight into the past climate […]
Although Mars presents a barren, dusty landscape with no signs of life so far, its geological features such as deltas, lakebeds, and river valleys strongly suggest a past where water […]
A research team using the ChemCam instrument onboard NASA’s Curiosity rover discovered higher-than-usual amounts of manganese in lakebed rocks within Gale Crater on Mars, which indicates that the sediments were […]
A recent paper may help explain why a portable chemistry lab on NASA’s Curiosity rover has continually sniffed out traces of the gas near the surface of Gale Crater.
The rover has arrived at an area that may show evidence liquid water flowed on this part of Mars for much longer than previously thought.
Discrepancies have emerged concerning the application of sulfur stable isotope ratios as a biosignature in impact crater paleolakes.
