NASA’s photos of Earth released during Artemis II’s mission around the moon show our planet against the dark backdrop of space. Auroras illuminated the thin atmosphere, city lights dotted the outline of continents, and brown deserts gave way to green vegetation.
 
Are those city lights normally this bright? What kind of clouds are swirling over the Atlantic Ocean? Is that hazy brown bit dust, or smoke, or something else?

To dig into the mysteries of our planet Earth, NASA has a fleet of satellites in orbit, gathering data around the clock. Join one of these satellites — the Plankton, Aerosol, Cloud, ocean Ecosystem satellite (PACE), which launched in February 2024 — to explore its unique views of our home planet’s ocean, atmosphere, and land surfaces.
