The report, published today in the Nature Geoscience journal, found it could take only five to ten minutes for the snow to descend one mile on Mars. French researchers had previously discovered that actual light snowfall seems to have occurred on Mars in 2008. They made the finding with the help of a laser aboard NASA’s Phoenix Mars Lander, a robotic spacecraft that landed on Mars in 2008.
However, data from NASA’s Reconnaissance Orbiter and Mars Global Surveyor now shows that on cold nights, when gusts of wind collide with clouds of water vapour in the Martian atmosphere with a certain amount of force, the water vapour transforms into icy particles that cause “microbursts” of snow flurries.
But these snowflakes are understood to be different than the ones seen on planet Earth.
