The Planetary Atmospheres and Exospheres group of the PSSC works on the origin, composition, dynamics, and evolution of solar system atmospheres. Shown here, such work includes Martian dust storms and weather, the Earth’s dynamic atmosphere and its interactions with space weather, and the methane-rich atmosphere of Titan as a possible analogue for Earth’s prebiotic world.
