The spacewalkers have successfully installed the Wide Field Camera 3 on Hubble and stowed the old camera, WFPC 2 (Photos), inside its protective enclosure for the return trip home. The spacewalkers’ next major task will be the replacement of the Science Instrument Command and Data Handling Unit.
The computer sends commands to Hubble’s science instruments and formats science data for transmission to the ground. The on orbit unit experienced computer anomalies in September 2008. NASA decided that the prudent thing to do was to delay the planned October 2008 launch of Atlantis on the Hubble servicing mission until this ground spare was ready to fly.

- Astronauts remove Hubble's first Wide Field and Planetary Camera to replace it with its more powerful successor, Wide Field and Planetary Camera 2, during Hubble’s first servicing mission in 1993. The camera, shaped something like a grand piano, weighs 610 pounds (277 kg) on Earth, but nothing in space. It can detect stars a billion times fainter than the ones we can see with our eyes. Most of Hubble’s most popular pictures have been taken with this second camera. (more)
