Space Shuttle Columbia wind down after STS-118. It was to service the Hubble Space Telescope two more times between 2004 and 2005, but no more missions were planned for it again except for a mission designated STS-144 where it would retrieve the Hubble Space Telescope from orbit and bring it back to Earth. Following the "Columbia" accident, NASA flew the STS-125 mission using "Atlantis", combining the planned fourth and fifth servicing missions into one final mission to Hubble. Because of the retirement of the Space Shuttle fleet, the batteries and gyroscopes that keep the telescope pointed will eventually fail also because of the
Space telescope 1971. Space telescopes are distinct from other imaging satellites pointed toward Earth for purposes of espionage, weather analysis and other types of information gathering. Wilhelm Beer and Johann Heinrich Mädler in 1837 discussed the advantages of an observatory on the Moon. In 1946, American theoretical astrophysicist Lyman Spitzer proposed a telescope in space, 11 years before the Soviet Union launched the first satellite, "Sputnik 1". Spitzer's proposal called for a large telescope that would not be hindered by Earth's atmosphere. After lobbying in the 1960s and 70s for such a system to be built, Spitzer's vision ultimately materialized into the
