Orbiting more than 200 miles (320 km) above Earth, the International Space Station (ISS) is a powerhouse of cutting-edge science and technology that unlocks discoveries in Space and our Universe. We’re testing technologies that are critical to our return to the Moon and contributing to medical and social breakthroughs that improve life on earth. After more than two decades of results, we continue to inspire future generations about the ISS with global collaboration improving and implementing sciences and technologies.
