The Hubble Space Telescope launched on April 24, 1990 and is celebrating its 35th anniversary in 2025.
The telescope has a 2.4-meter mirror, main types of science instruments, including a suite of spectrographs and cameras that have been upgraded through five astronaut-serviced missions.

Suspended in low-Earth orbit at an altitude of some 320 miles, far above the atmospheric distortions that blur ground-based views, Hubble promised to revolutionize astronomy. And though it had a bit of a bumpy start, over the past 35 years, it has done just that.
