HOUSTON (NASA PR) — The International Space Station has spent more than two decades in low-Earth orbit serving as Earth’s orbiting laboratory. Groundbreaking research aboard the station in its unique microgravity environment has led to benefits back on the ground and paved the way for future deep space missions.

KENNEDY SPACE CENTER, Fla. (NASA PR) — The 24^thSpaceX cargo resupply services mission, targeted to launch in late December from NASA’s Kennedy Space Center in Florida, carries scientific research and technology demonstrations to the International Space Station. The experiments aboard include studies of bioprinting, crystallization of monoclonal antibodies, changes in immune function, plant gene expression changes, laundering clothes in space, processing alloys, and student citizen science projects.
