Glaciers Tell A Story Of Ancient Mars
A new paper published in Icarus describes, maps and dates how glaciers and glacial runoff sculpted the northeastern rim of Mars’ Hellas basin over the last 3 billion years. The […]

Biosignatures: On The Peril of Inferring Phytoplankton Properties From Remote-Sensing Observations
Since 1978, sensors on remote-sensing satellites have provided global, multi-band images at optical wavelengths to assess ocean color. In parallel, sophisticated radiative transfer models account for attenuation and emission by […]

The Presence Of Liquid Water Is The Most Probable Explanation For Data Collected By Mars Insight
Data about Mars’ planetary crust gathered from the Mars InSight lander are best explained by the conclusion that the crust has stores of liquid water. Analysis led by Vashan Wright, […]

There Are Oceans Of Water On Mars. They’re Just Too Deep To Tap.
Using seismic activity to probe the interior of Mars, geophysicists have found evidence for a large underground reservoir of liquid water — enough to fill oceans on the planet’s surface.

Marsquakes May Help Reveal Whether Liquid Water Exists Underground On Mars
If liquid water exists today on Mars, it may be too deep underground to detect with traditional methods used on Earth. But listening to earthquakes that occur on Mars — […]
