International Astronauts

International astronauts are those individuals from international space agencies who have trained at Johnson Space Center and serve as mission specialists with NASA. Active international astronauts are those international astronauts who are assigned to duties at the Johnson Space Center.  Those international astronauts who are not located at the Johnson Space Center and have been reassigned by their space agency to other duties in their space programs are also annotated accordingly below. Some of these reassignments are of rotational nature, and those international astronauts may, on a case by case basis, return to the active status with NASA in the future.  There are currently 13 international astronauts assigned to duties at the Johnson Space Center.
