The International Space Station (ISS) is a multinational collaborative project between five space agencies around the world (NASA, Roscosmos, ESA, JAXA, CSA), which serves as a microgravity and space environment research laboratory for astrobiology, astronomy, meteorology, physics, and other fields. The ISS is suited for testing the spacecraft systems and equipment required for possible future long-duration missions to the Moon and Mars.



Since January 2023, all visiting missions to the space station are separated into their own co-dependent addons. These are the following:


  • This addon will replace the stock installation of the ISS.
  • Due to limitations of Celestia's own programming regarding orbits of artificial satellites, the orbit of the ISS does not reflect its real life trajectory, only its basic orbital information as of 2001-Apr-28 (i.e. the same as the default ISS's orbit)

The International Space Station (as of 2023-Mar-18)
