Hubble Space Telescope data, while the Goddard Space Flight Center controls the spacecraft. Space telescopes were proposed as early as 1923. Hubble was funded in the 1970s, with a proposed launch in 1983, but the project was beset by technical delays, budget problems, and the "Challenger" disaster (1986). When finally launched in 1990, Hubble's main mirror was found to have spherical aberration, compromising the telescope's capabilities. The optics were corrected to their intended quality by a servicing mission in 1993. Hubble is the only telescope designed to be serviced in space by astronauts. After launch by in 1990, five subsequent Space Shuttle missions
Space Shuttle crew members to the ISS, to stay docked for 180 days, and then return them back to Earth. These spacecraft were to become operational in the 2010s. Space Shuttles have been features of fiction and nonfiction, from children's movies to documentaries. Early examples include the 1979 "James Bond" film, "Moonraker", the 1982 Activision videogame "Space Shuttle: A Journey into Space" (1982) and G. Harry Stine's 1981 novel "Shuttle Down". In the 1986 film "SpaceCamp", "Atlantis" accidentally launches into space with a group of U.S. Space Camp participants as its crew. A space shuttle named "Intrepid" is featured in the 1989
