Hubble's journey and the technology that makes it possible

Launched in 1990, Hubble has been visited by astronauts four times in order to make repairs and add new instruments. Each instrument that flies on Hubble has special features that let astronomers study the heavens in different ways. Hubble’s unique capabilities can also be partnered with other space observatories and those on the ground to enable scientists to explore the universe in ways that no single mission could ever accomplish alone.
