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
Hubble Space Telescope 0.5–1.0 arcseconds, compared to a theoretical diffraction-limited resolution of about 0.05 arcsec for a telescope with a mirror in diameter. Second, a space-based telescope could observe infrared and ultraviolet light, which are strongly absorbed by the atmosphere. Spitzer devoted much of his career to pushing for the development of a space telescope. In 1962, a report by the US National Academy of Sciences recommended the development of a space telescope as part of the space program, and in 1965 Spitzer was appointed as head of a committee given the task of defining scientific objectives for a large space telescope.
