After many delays, as well as a reinstatemnet after its cancellation, STS 125 will fly to the Hubble Space Telescope to complete the final servicing mission. The mission will replace components as well as upgrade aspects of the Telescope, allowing it to continue to explore deep space until the James Clerk Maxwell telescope is launched to replace it in 2015.
