The chances of anything coming from Mars are a million to one they said

The chances of using that line in a thread about Mars - 100%

Yeh well, somehow "a Mars a day helps you work rest and play" just doesn't have the same impact

Clouds on Mars are quite common - whether it is water vapour, CO2 or dust.

Not like that though - its only been seen twice and it has the scientists stumped.

Seems to have gone up to around 200km above the Martian surface, twice the height of any clouds seen previously on Mars.

To put that into context - the highest altitude noctilucent clouds seen on Earth occur at around 85km.

Could be a low gravity volcano like the ones seen on Io ? ( http://en.wikipedia.org/wiki/Volcanology_of_Io )

If it were due to a volcanic eruption - it's likely that both the MRO and Mars Express would have seen some evidence of surface changes by now (both were in orbit at the time these plumes were observed).
