Hubble Space Telescope

This film, from Twig World, shows how scientists working on the Hubble Telescope, orbiting 400 miles above the Earth, fixed a fault by giving the telescope a pair of spectacles. The key points made in the film are: •The Hubble Telescope took eight years to build, from over 400,000 parts. •Initially, a fault in the Hubble telescope's mirror caused blurry images. •In 1993, the Hubble telescope's faulty mirror was repaired using Corrective Optics Space Telescope Axis Replacement, or COSTAR. •The Hubble telescope allows astronomers to see 10 billion light years into space.
