This artist's impression shows the Space Shuttle during the currently planned Servicing Mission (SM4) to repair and upgrade the NASA/ESA Hubble Space Telescope in 2008.
This Servicing Mission will not only ensure that Hubble can function for perhaps as much as another ten years, it will also increase its capabilities significantly in key areas.
As part of the upgrade, two new scientific instruments will be installed: the Cosmic Origins Spectrograph and the Wide Field Camera 3.
