Fixing the Hubble Space Telescope: A timeline of NASA's shuttle servicing missions

NASA astronaut Story Musgrave moves about in space shuttle Endeavour's cargo bay during the deployment of the solar array panels on the Hubble Space Telescope during the final of five STS-61 spacewalks, on Dec. 9, 1993. .

The Hubble Space Telescope is a masterwork of engineering and human ingenuity. Hubble is comparable in size and weight to a large school bus, but its contributions to science and astronomy could fill libraries.

Not only is Hubble one of Earth's premium sources for absolutely incredible, out-of-this-world imagery, it is also a testament to human curiosity and determination. The telescope has been in operation for over 30 years, undergone a total of five servicing missions and delivered nearly 250 terabytes of data in contributions to our understanding of the universe.
