Space Shuttle Atlantis with Hubble

This artist's concept shows the space shuttle Atlantis hovering above the Earth. As the shuttle turns, it reveals the NASA/ESA Hubble Space Telescope attached to the shuttle via its robotic arm. Servicing Mission 4 will be the fifth and final visit to Hubble. The primary objective of the mission is to deliver two new instruments. The Cosmic Origins Spectrograph (COS) will sit in the slot currently occupied by the now redundant COSTAR package and the enhanced Wide Field Camera 3 (WFC3) will replace the current WFPC2. Both instruments use advanced technology to improve Hubble's potential for discovery dramatically and enable observations of the faint light from the youngest stars and galaxies in the Universe.
