Observations of large valley networks on today’s Mars suggest formation by flowing water. However, most climate models cannot sustain temperatures above...
NASA’s Curiosity rover has found evidence of a carbon cycle on ancient Mars, bringing scientists closer to an answer on whether the planet was ever capable...
Recent measurements from NASA’s InSight mission show that Mars’ core is less dense than planetary scientists previously believed. This indicates that...
Called ferrihydrite, this iron mineral formed during a cold, wet period on early Mars under oxidative conditions, followed by a transition to the current...
A team of planetary researchers led by Caltech has determined the chemical mechanisms by which the ancient Mars was able to sustain enough warmth in its...
Scientists from Curtin University and the University of Adelaide have analyzed a 4.45-billion-year-old zircon grain from a famous Martian meteorite called...
Sedimentary mineral deposits found on the surface of Mars may have been left by an ancient sea 3.5 billion years ago. New results from China’s Tianwen-1/Zhurong...
Carbonate minerals are of particular interest in paleoenvironmental research as they are an integral part of the carbon and water cycles, both of which...
Geological observations of Mars indicate a dense early atmosphere ranging from 0.25 to 4 bar of carbon dioxide. But 3.5 billion years ago, the Martian...
This new image from the High Resolution Stereo Camera (HRSC) onboard ESA’s Mars Express spacecraft shows Caralis Chaos, broken-down and dried-up remnants...
In a new study, planetary scientists found strong similarities between soils found in Gale Crater on Mars and those of Canada’s Newfoundland, a cold...
The history of water on Mars is a puzzle that is of interest to planetary scientists as well as the general public. The Red Planet currently has water...
The relatively well-preserved ancient crust of Mars provides a natural window into early planetary evolution not available on Earth. Mars has generally...
Ancient river deposits exist across Mars and can be identified in satellite data by erosional landforms called fluvial ridges. Fluvial ridges take the...
New observations of mud cracks made by NASA’s Curiosity rover show that high-frequency, wet-dry cycling occurred in early Martian surface environments,...
A major question in Mars history is whether the planet had an ocean in its northern hemisphere. New research provides evidence for a northern ocean or...
The subsurface of Mars during the Noachian period was likely to have been habitable for microorganisms that feed on hydrogen and produce methane, according...
Massive floods from overflowing crater lakes were responsible for eroding at least 24% of the volume of incised valleys on early Mars, according to new...
