Could martian liquid water hold enough oxygen to support life?

A team led by scientists at Caltech and the Jet Propulsion Laboratory (JPL), which Caltech manages for NASA, has calculated that if liquid water exists on Mars, it could — under specific conditions — contain more oxygen than previously thought … Continue reading

Portable radar unit could help astronauts hunt for water on Mars

Analogue astronauts have successfully trialed a radar that could help future Mars explorers identify where to dig for water. ScanMars is an Italian experiment that was used to identify subsurface water features in the Mars-like Dhofar region of Oman during … Continue reading

Mars Express: From worry to water

In 2004, a year after Europe’s first mission to Mars was launched, the flight dynamics team at ESA’s operations centre encountered a serious problem. New computer models showed a worrying fate for the Mars Express spacecraft if mission controllers continued … Continue reading

History of Mars’ water, seen through the lens of Gale Crater

The surface of Mars today is cold, dry, and inhospitable to life. But was it always so? Past research indicates that the Red Planet may have been a very different world more than 3 billion years ago, with warmer weather, … Continue reading

Dormant microbial life in Atacama Desert goes active when wet — true for Mars, too?

It may rain once a decade or less in South America’s Atacama Desert, but tiny bacteria and microorganisms survive there, hinting at the possibility of similar life on Mars, researchers said Monday. [Their report was published in the Proceedings of … Continue reading

Mars: not as dry as it seems

When searching for life, scientists first look for an element key to sustaining it: fresh water. Although today’s Martian surface is barren, frozen and inhabitable, a trail of evidence points to a once warmer, wetter planet, where water flowed freely. … Continue reading

Clays quickly cooked in early Mars steambath

New research suggests that the bulk of clay minerals on Mars could have been formed as the planet’s crust cooled and solidified, not by later interactions with water on the surface as has long been assumed. (…) There are thousands … Continue reading

Shock tests on synthetic Mars-meteorite mineral suggest a more water-rich history

Mars may have been a wetter place than previously thought, according to research on simulated Martian meteorites conducted, in part, at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab). In a study published [March 6, 2017] in the … Continue reading

Curiosity findings from Yellowknife Bay sharpen CO2 paradox of ancient Mars climate

Mars scientists are wrestling with a problem. Ample evidence says ancient Mars was sometimes wet, with water flowing and pooling on the planet’s surface. Yet, the ancient sun was about one-third less warm and climate modelers struggle to produce scenarios … Continue reading
