“On Mars, these are the last things you would expect to move, because you need really strong wind to displace even regular sand,” Silvestro said, adding that “the atmosphere of Mars is always surprising — it can do what you would not expect for such a faint atmosphere.“
The findings were unexpected, Silvestro said, because megaripples are made up of coarse grains of sand, particularly at the crests of the rippled features. Fine particles of dust can blow around during Martian dust storms, but it was not previously known if the wind on Mars was powerful enough to sculpt megaripples.
The scientists are planning to expand their focus to include other sites on Mars, including one near the planet’s northern polar region. Silvestro said the research could inform future human exploration of the planet, as scientists will need to understand how the Martian climate may affect astronaut crews.
“We haven’t checked if they are active or not, but there are megaripples about 200 kilometers [about 124 miles] from the Perseverance landing site,” he said.
if Mars has no air, how on earth '...Mars may actually be windier...'?
All y’all had to do was ask. I could’ve told you all that.
