Hubble

Our eye on outer space

Suddenly, it happens. In a long-term research project, a breakthrough suddenly occurs or chance plays into the hands of the researchers. A new crucial discovery is made.


ON 24 APRIL 1990, the Hubble Space Telescope, named after American astronomer Edwin Hubble, was launched into orbit using the Discovery Space Shuttle. The launch went well, but it soon became clear that the costly telescope was not delivering images of the quality anticipated. It turned out that Hubble’s mirror had been polished incorrectly!

BUT SHAME ON ANYONE who gives up. In December 1993 technicians installed a corrective lens on the large telescope to fix the problem; Hubble had gotten glasses. Since then the telescope has been serviced and upgraded several times,and it continues to deliver great images that provide invaluable knowledge from its orbit about 550 km above the Earth’s surface.
