The science never stops on the International Space Station 🌱
At any given time, up to 100 scientific experiments are running at once on the @ISS's EXPRESS Racks, from cutting-edge medical research to orbiting veggie gardens that're helping us learn how to grow plants in space.
The refrigerator-sized lockers can be operated directly by our @NASAAstronauts (like @astro_kayla is here)—or controlled from the ground by a team of experts working around the clock at @NASA_Marshall's Payload Operations Integration Center. Thanks to this 24/7 collaboration, our EXPRESS racks just logged their 1,000,000th hour of combined powered duty: that's nearly 115 years' worth of research in just over two decades!
Even with all this science, the EXPRESS Racks are just one of the many research facilities on our orbiting laboratory. Check out nasa.gov/iss for the latest updates from the International Space Station!
