Lake under south polar ice cap requires local heat source
Thermal modeling suggests that active magmatism in the past few hundred thousand years could account for the presence of a large lake previously hypothesized beneath the Red Planet’s southern ice cap. Liquid water appears to be a fundamental requirement for … Continue reading

Volcanism under the south pole ice cap of Mars?
A study published last year in the journal Science suggested liquid water is present beneath the south polar ice cap of Mars. Now, a new study in the AGU journal Geophysical Research Letters argues there needs to be an underground … Continue reading

Do slope streaks show global-scale water processes on Mars today?
[Editor’s note: From a paper by Anshuman Bhardwaj and three co-authors recently published in Reviews of Geophysics.] Are Slope Streaks Indicative of Global‐Scale Aqueous Processes on Contemporary Mars? • We provide a systematic survey and evaluation of the literature covering … Continue reading

Mars Express: Shaping the surface with water, wind, and ice
ESA’s Mars Express has imaged an intriguing part of the Red Planet’s surface: a rocky, fragmented, furrowed escarpment lying at the boundary of the northern and southern hemisphere. This region is an impressive example of past activity on the planet … Continue reading

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
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

Mars Express radar finds liquid water under Mars south polar region
Editor’s note: NASA has commented on this discovery. Radar data collected by ESA’s Mars Express point to a pond of liquid water buried under layers of ice and dust in the south polar region of Mars. [The researchers’ paper reporting … 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
