STS-125 is the fifth and final mission to the Hubble Space Telescope. This mission is one of the more risky missions ever taken on using a Space Shuttle. The main reason why this is risky is because the shuttle will be unable to dock with the International space station in the event that something does happen. Because of this, it will be required that a backup shuttle be placed on launch pad 39B. In this mission astronauts will:

• Replace the fine guidence sensor
• Replace six gyroscopes
• Change Batteries
• Install new thermal blanket
• Install soft-capture mechanism (for deorbiting)
• Repair Advanced Camera for Surveys (ACS)
• Replacement of the Data Handling Units (which failed in Sept.)
• Installation of the Cosmic Origins Spectrograph (COS)
• Installation of Wide Field Camera 3
