What’s really happening in the Martian sky? Scientists are eager to find out, and the public can help. Cloudspotting on Mars invites participants to examine NASA images for signs of clouds above the Red Planet, contributing to real scientific research on daily and seasonal weather patterns.

Using data from the Mars Climate Sounder aboard the Mars Reconnaissance Orbiter, participants will help identify high-altitude water-ice and carbon-dioxide clouds. These observations support ongoing research into Mars’s climate and offer clues about the planet’s past, including conditions that may once have supported liquid water. Participants will learn how to recognize and label cloud features so scientists can study how Martian clouds form and evolve over time.

This program will be in-person, livestreamed by SciStarter, at the Granville Branch, allowing participants to contribute data and chat with scientists in real time. Attendees should bring their own devices, laptops are recommended, followed by tablets, and charging cords for the two-hour program.

The event is part of Acts of Science: Connected, a Citizen Science Month collaboration with SciStarter and NASA Citizen Science. No science background is required, just curiosity and an interest in exploring Mars. The program is free and open to the public.
