Mars Rover Curiosity is above all a robot geologist, but that’s not stopping it from tracking weather on the Red Planet as well. And what strange weather it is. The latest exciting result from Curiosity: atmospheric pressures at some places on Mars swing wildly throughout the day.
We’ve long known that temperatures on Mars can vary widely over the course of a single Martian day, as its thin atmosphere and lack of stabilizing oceans make it particularly sensitive to the coming and going of the suns rays. But what we didn’t know (though we previously have theorized) is that barometric pressures change radically throughout the day as well, at least in certain places.
