NASA boasts a strong presence on the International Space Station (ISS) as Mission Specialists conduct vital research and work with developing technologies that will impact life in space and on Earth.

For each Expedition (e.g., 31, 32)—approximately every three months—3 astronauts (one U.S.) go up to the ISS, and 3 astronauts (one U.S) return home.
