The hull can now be seen in the National Air and Space Museum, in Washington DC, where it is a popular tourist attraction. A number of additional Salyuts were also produced, as backups or as flight articles that werelater canceled.

• The U.S. Space Station Freedom program, which—despite being under development for ten years—was never launched, evolved into the International Space Station, incorporating elements of the also canceled Russian Mir-2 station, which was never constructed.

• Other canceled space station programs included the United States Air Force Manned Orbiting Laboratory project, canceled in 1969, about a year before the first planned test flight; this was unusual in being an explicitly military project, as opposed to the Soviet Almaz program, which was heavily intertwined with—and concealed by—the contemporaneous Salyut program.

• The European Columbus project planned to create a small space station serviced by the Hermes shuttle. It evolved into the ISS Columbus module.                                                                                                                                                                                                                                                                                                                                                                                                                                    
• worldwide to pursue careers in science, technology, engineering and mathematics through amateur radio communications opportunities with the ISS crew. ARISS is an international working group, consisting of delegations from 9 countries including several countries in Europe as well as Japan, Russia, Canada, and the United States. In areas where radio equipment cannot be used, speakerphones connect students to ground stations which then connect the calls to the station.

• First Orbit is a feature-length documentary film about Vostok 1, the first manned space flight around the Earth. By matching the orbit of the International Space Station to that of Vostok 1 as closely as possible, in terms of ground path and time of day, documentary filmmaker Christopher Riley and ESA astronaut Paolo Nespoli were able to film the view that Yuri Gagarin saw on his pioneering orbital space flight. This new footage was cut together with the original Vostok 1 mission audio recordings sourced from the Russian State Archive. Nespoli, during Expedition 26/27, filmed the majority of the footage for this documentary film, and as a result is credited as its director of photography.[64] The film was streamed through the website firstorbit.org in a global YouTube premiere in 2011, under a free license.

• In May 2013, commander Chris Hadfield shot a music video of David Bowie's Space Oddity on board the station; the film was released freely on YouTube. It was the first music video ever to be filmed in space
