Astronauts complete Hubble repairs

摘要

The Hubble Space Telescope has had its vision refreshed. On 18 May, astronauts completed the final overhaul of the ageing astronomical icon. The mission has included installing a new camera, a new spectrograph and making repairs to two other instruments (see Nature 459, 21; 2009).rnThe servicing - involving five days of spacewalks (pictured) from the Atlantis space shuttle - also included new batteries, gyroscopes and repairs to the telescope's thermal insulation.
