1990: First image sent from Hubble Space Telescope
The Hubble Space Telescope sends back its first image on 20 May 1990.
The telescope was launched on 24 April 1990 by the space shuttle Discovery. It had taken 20 years to build, at a cost of $1.55 billion.
Hubble鈥檚 first images revealed a tiny error in the manufacture of the telescope鈥檚 mirror, which was eventually repaired while in orbit in December 1993.
