The Hubble Space Telescope is deployed from NASA's space shuttle Discovery on April 25, 1990. Getting Hubble developed and launched cost $1.5 billion, but there would be ongoing costs as well - both expected and unexpected. Hubble finally launched aboard the space shuttle Discovery on Apand a day later was deployed into low Earth orbit, about 340 miles (545 kilometers) above our planet. It was more than 2.5 years before shuttle flights resumed and NASA could begin planning Hubble's launch again. 28, 1986, killing all seven astronauts on board. Hubble's planned liftoff was delayed again after the space shuttle Challenger exploded a minute after takeoff on Jan. In the meantime, the Large Space Telescope was renamed Hubble in honor of Edwin Hubble, an American astronomer who, among other things, determined that the universe extended beyond the borders of the Milky Way. NASA planned to launch the telescope in 1983, but various production delays pushed the launch date back to 1986. Congress eventually granted funding for NASA's portion of the Large Space Telescope in 1977.ĭevelopment began almost immediately. NASA then upped its lobbying efforts and got buy-in from European Space Agency, which shared the costs. The expensive project was a tough sell, and funding was initially denied by the House Appropriations Subcommittee in 1975.

The Hubble Space Telescope went through many years of development. In 1971, George Low, the agency's acting administrator at the time, greenlit the Large Space Telescope Science Steering Group, and NASA soon began lobbying Congress for funding for the endeavor. NASA was already considering a space telescope of some type, but the agency was undecided about how big to make it and where to start. The National Academy of Sciences took the pitch to NASA - the only agency capable of making the Large Space Telescope a reality. National Academy of Sciences to organize a committee of scientists to evaluate the potential of a "Large Space Telescope." With Spitzer at the helm, the committee published a document in 1969 that outlined the scientific uses of a Large Space Telescope and advocated for its construction, according to a Hubble history written by Gabriel Olkoski for NASA (opens in new tab). It took a couple more decades before the idea garnered enough support for the U.S. In 1946, soon after World War II, astronomer Lyman Spitzer proposed launching a space telescope, which could overcome the limitations of ground-based observatories.
