Hubble Timeline

Follow Hubble's journey from an idea of a "Large Space Telescope" to its position as one of the most scientifically productive and beloved telescopes of all time. The timelines below offer an interactive selection of Hubble highlights.

Quick Facts

Since launch, Hubble has overcome its troubled beginnings to perform innumerable science observations that have revolutionized humanity’s understanding of the universe. From determining the age of the universe to observing dramatic changes on celestial bodies in our own solar system, Hubble has become one of humanity’s greatest scientific instruments.

The complete timeline below describes Hubble’s history from the first proposal of a space telescope by Lyman Spitzer in 1946, through the completion of Hubble’s five servicing missions in the 1990s and 2000s, and to many of the significant observations and discoveries Hubble has made during its years in orbit.
