Detecting carbonates on the martian surface
Was Mars warm and wet enough to support life during the planet’s first few hundred million years? Scars of ancient lakes and rivers, as well as minerals that form only when water is present, have convinced many researchers that Mars … 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

CRISM: Hydrated minerals in Chryse Planitia
The Chryse Planitia is a smooth circular plain that has a diameter of 1600 km, and has a depth of 2.5 km below its average surface altitude, making it one of Mars’s lowest regions. Chryse Planitia was a landing site … Continue reading
CRISM: Phyllosilicate minerals near Mawrth Vallis
This image, which covers a site located slightly west of the Mawrth Vallis outflow channel, shows aluminum-containing minerals called phyllosilicates in a cyan color and iron-magnesium-containing phyllosilicates in a red/magenta color. Phyllosilicates are clay and clay-like minerals formed by chemical … Continue reading

Opportunity explores aluminum-bearing site
With its solar panels their cleanest in years, NASA’s decade-old Mars Exploration Rover Opportunity is inspecting a section of crater-rim ridgeline chosen as a priority target due to evidence of a water-related mineral. Orbital observations of the site by another … Continue reading

CRISM: Aluminum and iron/magnesium clays in Mawrth Vallis
This image, which covers a site located northeast of Oyama Crater, shows aluminum-containing minerals called phyllosilicates in a cyan color and iron-magnesium-containing phyllosilicates in a red/magenta color. Phyllosilicates are clay and clay-like minerals formed by chemical reactions with liquid water. … Continue reading

Opportunity hunts ancient clays
From A.J.S. Rayl’s blog at The Planetary Society: “At the western rim of Endeavour Crater, Opportunity spent the month of May exploring a new clayground along Murray Ridge and the Mars Exploration Rovers (MER) mission trundled into the 125th month … Continue reading

CRISM: Aluminum phyllosilicates in Mawrth Vallis
This image is located right along the dichotomy boundary within a drainage channel named Mawrth Vallis. Here we see aluminum phyllosilicates (cyan to blue) exposed on the rim of a crater. Phyllosilicates are clay and clay-like minerals formed by chemical … Continue reading
