Rover Accidentally Uncovers Mars Hydrothermal Vent 53

Posted by ScuttleMonkey on Saturday May 24, 2008 @04:04AM from the best-discoveries-by-accident dept.

The rover Spirit has been dragging one wheel around the surface of Mars for some time. One of the resulting gouges revealed a mineral deposit which was probably caused by a hydrothermal vent. This implies a large amount of water was present when the vent was active.

I thought of this at first, but Lake Nyos was a crater lake that flooded an adjacent valley with CO2. I doubt that these caverns have the same possibility to allow the CO2 to flow down hill and "pool" in to an area below sea level.
