The Hubble Space Telescope was launched by the Space Shuttle in April 1990. This is not an exploration probe moving away from the Earth vicinity, but it is an orbiting telescope that overcomes the Earth's atmosphere and distinguishes details on the surface of planets. Images sent by Hubble are of excellent quality, especially since it was repaired in 1993 by astronauts from the space shuttle.
The Hubble telescope is managed from the Space Science Institute in Baltimore (USA) as an automatic telescope. It was repaired again in 1999 (change of gyroscopes) to remain operational in the coming years.
