The Tsiolkovsky International Space Film Festival (Tsiolkovsky ISFF) is an annual event held in Kaluga, Russia, dedicated to films and programs about space, its exploration, and its relationship with science, art, and culture. The festival aims to showcase new space-themed films and promote various areas of science and art connected to space, fostering international dialogue between scientists and filmmakers. It features competitive, non-competitive, and retrospective screenings, and its jury includes professional filmmakers, astronauts, and scientists from the space industry. The festival's logo is based on a drawing by Konstantin Tsiolkovsky, a pioneer of astronautics, from his "Album of Space Travel" created for the first Soviet science fiction film "Space Flight."
