Fact Sheet
Good to Go
Astronaut Michael Good works inside Hubble Space Telescope on May 17 during the fourth of five spacewalks to repair and upgrade the orbiting observatory. During the spacewalks, Good and three other astronauts replaced several scientific instruments along with the telescope's batteries, three gyroscopes, and failed electronics units. They also repaired two other instruments. Astronomers hope the repairs, along with a boost to a higher altitude, will keep the telescope going for another five years. [NASA]
