Full Version: More Water Clues From Mars Express
Unmanned > Mars & Missions > Orbiters > Mars Express & Beagle 2
But now, new data from the Omega visible and near-IR imaging spectrometer onboard Mars Express has found a large region - 60 kilometres by 200 km - that shows the clear spectral signature of calcium-rich sulphates, probably gypsum. This means that at least a portion of that northern "ocean" area was indeed covered by standing water for a long time.

Formaldehyde, frozen sea, and now possibly gypsum. What is going on?

Gypsum has been mentioned (along with magnesium sulfate) so often with respect to the MER missions, that somehow, I do not find it such a big deal that more of it was discovered.
If it was carbonates, that would be a whole new ballgame smile.gif

ESA has released more high-res images of the ice-patch in the northern crater, at:

There are also context maps giving the location.
