Hubble was built with a number of instruments onboard, including the Wide Field Planetary Camera (WFPC), the Goddard High Resolution Spectrograph (GHRS), the Faint Object Camera (FOC), the Faint Object Spectrograph (FOS) and the High Speed Photometer (HSP).

For 35 years, the Hubble Space Telescope has taken photos of celestial objects across the universe. Look back at 10 photos taken by the telescope orbiting above Earth's surface.

Astronauts repaired and upgraded NASA's Hubble Space Telescope over the course of five servicing missions from 1993 to 2009. Could yet another astronaut visit be in the cards?
