THEMIS: Crater – false color
THEMIS Image of the Day, March 30, 2015. The THEMIS VIS camera contains 5 filters. The data from different filters can be combined in multiple ways to create a false color image. These false color images may reveal subtle variations … Continue reading

CRISM: Iron-magnesium clays at Isidis Basin rim
This image is located right along the rim of the Isidis impact basin, at the foot of Libya Montes. Here we see iron-magnesium phyllosilicates (cyan). Phyllosilicates are clay and clay-like minerals formed by chemical reactions with liquid water. They are … Continue reading
Finding Beagle 2
The UK-led Beagle 2 Mars Lander, thought lost on Mars since 2003, has been found partially deployed on the surface of the planet, ending the mystery of what happened to the mission more than a decade ago. Images taken by … Continue reading

HiRISE: Impact crater in Isidis Planitia
This recent observation is the fifth time we’ve imaged this spot on Mars. We often re-image spots on the surface to search for, or track changes, due to active processes, such as migrating sand dunes. In this case, there isn’t … Continue reading

CRISM: Phyllosilicate minerals at Isidis rim
This image is located right along the rim of the Isidis impact basin, at the foot of Libya Montes. Here we see the stratigraphy (layering) of different iron-magnesium phyllosilicates (white and pink). Phyllosilicates are clay and clay-like minerals formed by … Continue reading

Changing times in Syrtis Major
Early Mars appears to have been highly unlike today, being warmer and wetter. To find out why and how the environment changed, scientists look for inflection points in Martian history, where one geological regime gives way to another. A report … Continue reading

Sea cliffs in Libya Montes?
New work suggests that three possible shorelines from ancient lakes or seas in Isidis Planitia lie in Libya Montes. These mountains form the southern rim of Isidis, a Noachian-age impact basin 1,225 kilometers (760 miles) in diameter. They lie along … Continue reading
