Home This diagram illustrates Mars’ “thermal tides,” a weather phenomenon responsible for large, daily variations in pressure at the Martian surface. Sunlight heats the surface and atmosphere on the day side of the planet, causing air to expand upwards.

This graphic shows the pattern of winds predicted to be swirling around and inside Gale Crater, which is 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 (REMS). (Image credit: NASA/JPL-Caltech/ESA/DLR/FU Berlin/MSSS)
