Mars CO2 ice cap throughout the martian year
This animation shows a side-by-side comparison of CO2 ice at the north (left) and south (right) Martian poles over the course of a typical year (two Earth years). This simulation isn’t based on photos; instead, the data used to create … Continue reading

Mars orbiters reveal seasonal dust storm pattern
After decades of research to discern seasonal patterns in Martian dust storms from images showing the dust, but the clearest pattern appears to be captured by measuring the temperature of the Red Planet’s atmosphere. For six recent Martian years, temperature … Continue reading

Tallying up where the Martian carbon went
Scientists may be closer to solving the mystery of how Mars changed from a world with surface water billions of years ago to the arid Red Planet of today. A new analysis of the largest known deposit of carbonate minerals … Continue reading

Are brines actually needed to make recurring slope lineae flow?
Recurring slope lineae (RSL) are finger-like dark lines on steep slopes that appear and grow longer during the warmest time of year, then fade and disappear over winter. They repeat the following Mars year in the same places. While scientists … Continue reading

Ancient Mars biosphere: deep underground?
Something like half of Earth’s entire biomass lies underground in the form of microorganisms living off geothermal heat and chemicals in the crustal rocks. Could the same hold true for Mars, now or in bygone times? If so, it’s hard … Continue reading

Lava flows resurfaced crater lakes after water was gone
Fire and water didn’t mix when it came to resurfacing basins that lie along Martian fluvial valley networks. A study of some 30 open-basin lakes (paleolakes) with floors covered by lava flows has concluded that at least these basins were … Continue reading
