Mysterious White Cloud Hangs Over Martian Volcano (vice.com) 59
Last month, the European Space Agency's Mars Express orbiter spotted a white cloud suspended over the western slope of Arsia Mons, an enormous volcano near the red planet's equator. The 930-mile-long cloud looks like the kind of volcanic plumes huffed out by Earth's active volcanoes -- but it's not; "Arsia Mons is long extinct -- its last eruption is estimated to have occurred around 50 million years ago," reports Motherboard. From the report: The volcano still plays a role in shaping the water-ice cloud, though, along with atmospheric dust levels and the Martian seasons. With its 12-mile-high peak and diameter of nearly 400 miles, Arsia Mons is 30 times more voluminous than the largest volcanoes on Earth. Its humongous bulk condenses and cools air currents as they pass over the summit, creating this âoeorographic cloudâ -- a nephologic formation that tend to form over leeward (downwind) slopes -- on the western flank of the volcano.

Mars has an atmosphere, not air.

Air and atmosphere are used interchangeably. you can find articles on the offical NASA website referring to "martian air". Case in point, these articles found with Google. You can email NASA that they're doing it wrong.

So what are we supposed to call the currents in the gas around Mars then? Gas currents? Methane Currents? Martian Atmospheric Gas Flow Movements? MAGFMs?
Seriously, Air Currents are a good enough analogue.

A few answers...
1) They did not spend "2 days" in the belts. They "rocketed through" at earth escape velocity.
2) You're talking about the radiation in space. The w

Like a lenticular cloud (Score:3)
Lenticular clouds [wikipedia.org] are also created by air currents being lifted over mountains (or other terrain features). But they tend to disappear a short distance downwind of this point due to the air descending and the condensation re-evaporating. Either meteorology and thermodynamics are vastly different on Mars than on Earth, or this appears to be some gas venting from the summit.
