• Zenith 1 Patch Panel reconfiguration
• Installation of 6 Station-to-Shuttle Power Transfer System (SSPTS) floating power connector grounding sleeves.
• Deployment of Lower Inboard PAS and open target cover [for STS-133]
• Tuck down Lab/Node 2 cables
• Install JPM spacewalk handrails and worksite interfaces.
• Install gap spanner to replace Harmony handrail
• Reboost station (if needed)
• Perform imagery survey during fly around
• Perform an additional four hours handover per rotating crew member
• Perform Maui Analysis of Upper Atmosphere (MAUI), Shuttle Exhauster Ion Turbulence Experiments (SEITE), and SIMPLEX (payloads of opportunity – not during docked operations)
• Perform Station Detailed Test Objective 1300-U, ISS Structural Life Validation and Extension during Shuttle Mated Reboost and undocking.

Launch: May 11,2009 2:01PM EST (18:01 UTC)
Landing: May 22,2009 11:41AM EST (15:41 UTC)

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
