Captured in 2012 by NASA’s Mars Reconnaissance Orbiter (MRO), the dust plume reached around 20 km into the thin Martian atmosphere, and the funnel itself was roughly 140 metres in diameter.
These dust devils are common in this region of Mars in spring and summer, when the Sun heats up the surface, and warm, rising air currents being to rotate.
According to other images captured by the MRO’s onboard HiRISE camera, it’s estimated that wind speeds for these little sand tornadoes can reach 110 km/hour. You can even see some footage of other Martian dust devils here.
While they look impressive, we’re glad we’re not experiencing them up close.
