This graphic shows the pattern of winds predicted to be swirling around and inside Gale Crater, where NASA's Curiosity rover landed on Mars. Modeling the winds gives scientists a context for the data from Curiosity's Rover Environmental Monitoring Station
This image maps the traverse of NASA's Mars rover Curiosity from 'Bradbury Landing' to 'Yellowknife Bay,' with an inset documenting a change in the ground's thermal properties with arrival at a different type of terrain.
Twenty-one times during the first 12 weeks that NASA's Mars rover Curiosity worked on Mars, the rover's Rover Environmental Monitoring Station (REMS) detected brief dips in air pressure that could be caused by a passing whirlwind.
Atmospheric Pressure Patterns Before and During Dust Storm
This graph compares a typical daily pattern of changing atmospheric pressure (blue) with the pattern during a regional dust storm hundreds of miles away (red). The data are by the Rover Environmental Monitoring Station (REMS) on NASA's Curiosity rover.
This graph shows the atmospheric pressure at the surface of Mars, as measured by the Rover Environmental Monitoring Station on NASA's Curiosity rover. Pressure is a measure of the amount of air in the whole column of atmosphere sitting above the rover.
This graphic tracks the maximum relative humidity and the temperature at which that maximum occurred each Martian day, or sol, for about one-fourth of a Martian year, as measured by REMS on NASA's Curiosity Mars rover.
Weather Sensors from Spain on Mars Rover Curiosity
Sensors on two finger-like mini-booms extending horizontally from the mast of NASA's Mars rover Curiosity will monitor wind speed, wind direction and air temperature; image taken during installation of the instrument inside a clean room at NASA's JPL.
The Rover Environmental Monitoring Station (REMS) on NASA's Curiosity Mars rover has detected dozens of whirlwinds, or vortex events, causing brief dips in atmospheric pressure, and sometimes other measurable effects.
