Station Facts and Figures
Crew members live and work aboard the International Space Station orbiting Earth 16 times a day. The orbital outpost is larger than a six-bedroom house with six sleeping quarters, two bathrooms, a gym, and a 360-degree view bay window.

NASA Astronaut Record Holders
Astronaut Frank Rubio holds the NASA record for the longest single spaceflight. Astronaut Peggy Whitson holds the NASA record for most cumulative days in space.
Meet the Station Record Holders![NASA astronaut Frank Rubio completed a single mission aboard the International Space Station of 371 days on Sept. 27, 2023. Rubio surpasses NASA astronaut Mark Vande Hei who ended his mission after 355 days on March 30, 2022.](https://www.nasa.gov/wp-content/uploads/2023/05/single-spaceflight-info8.jpg?w=1024)
International Cooperation
An international partnership of space agencies provides and operates the elements of the International Space Station. The principals are the space agencies of the United States, Russia, Europe, Japan, and Canada. The orbital outpost has been the most politically complex space exploration program ever undertaken.
