ISS@25: What We Learn

We’re celebrating 25 years of International Space Station operations! The International Space Station advances scientific knowledge in Earth, space, physical, and biological sciences, for the benefits of people living on our home planet.

Through this global endeavor, 273 people from 21 countries have visited the unique microgravity laboratory that has hosted more than 3,000 research and educational investigations from people in 108 countries and areas.

The space station is a proving ground for long-duration spaceflight, including how humans will live and work around the Moon as part of Artemis.
