CAPE CANAVERAL, Fla. – STS-125 Mission Specialist Michael Good puts on his launch-and-entry suit before heading for Launch Pad 39A at NASA's Kennedy Space Center in Florida. This launch will be Good's first space shuttle flight. Liftoff is scheduled for 2:01 p.m. May 11 EDT. Atlantis' 11-day flight will include five spacewalks to refurbish and upgrade NASA's Hubble Space Telescope with state-of-the-art science instruments that will expand Hubble's capabilities and extend its operational lifespan through at least 2014. The payload includes a Wide Field Camera 3, fine guidance sensor and the Cosmic Origins Spectrograph. Photo credit: NASA/Kim Shiflett KSC-2009-3043

CAPE CANAVERAL, Fla. – Technicians in the Payload Hazardous Servicing Facility remove the protective cover from the Wide Field Camera 3, or WFC3. The WFC3 is part of the payload on space shuttle Atlantis for the fifth and final Hubble servicing mission, STS-125. As Hubble enters the last stage of its life, WFC3 will be Hubble's next evolutionary step, allowing Hubble to peer ever further into the mysteries of the cosmos. WFC3 will study a diverse range of objects and phenomena, from young and extremely distant galaxies, to much more nearby stellar systems, to objects within our very own solar system. WFC3 will take the place of Wide Field Planetary Camera 2, which astronauts will bring back to Earth aboard the shuttle. Launch of Atlantis is targeted at 1:34 a.m. EDT Oct. 8.

CAPE CANAVERAL, Fla. – Inside a test cell in the Vehicle Assembly Building at NASA's Kennedy Space Center, a portion of Atlantis’ external tank is sealed to prevent contamination so that technicians can replace a valve after small dings were found on the sealing surface of the quick disconnect system that handles liquid-hydrogen fuel for the shuttle’s three main engines. The tank will be attached to the twin solid rocket boosters on Aug. 3 for the STS-125 mission, the fifth and final shuttle servicing mission to NASA’s Hubble Space Telescope. During the mission, the crew will install new instruments on the telescope, including the Cosmic Origins Spectrograph and the Wide Field Camera 3. A refurbished Fine Guidance Sensor will replace one unit of three now onboard. Mission specialists will also install new gyroscopes, batteries and thermal blankets on the telescope. Launch is targeted for Oct. 8. Photo credit: NASA/Jim Grossmann KSC-08pd2152

CAPE CANAVERAL, Fla. – After rotation of the Wide Field Camera 3 (background left), or WFC3, in the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center, technicians check the data. The WFC3 will be transferred to the Super Lightweight Interchangeable Carrier. WFC3 is part of the payload on space shuttle Atlantis' STS-125 mission for the fifth and final Hubble servicing flight to NASA's Hubble Space Telescope. The curved edge shown at top is the radiator, the "outside" of WFC3 that will be exposed to space and will expel heat out of Hubble and into space through black body radiation. As Hubble enters the last stage of its life, WFC3 will be Hubble's next evolutionary step, allowing Hubble to peer ever further into the mysteries of the cosmos. WFC3 will study a diverse range of objects and phenomena, from young and extremely distant galaxies, to much more nearby stellar systems, to objects within our very own solar system.

This color image of Saturn was taken with the Hubble Space Telescope's (HST's) Wide Field Camera (WFC) at 3:25 am EDT, August 26, 1990, when the planet was at a distance of 2.39 million km (360 million miles) f... More

STS125-S-001 (December 2007) --- This STS-125 crew patch shows HST along with a representation of its many scientific discoveries. The overall structure and composition of the Universe is shown in blue and filled with planets, stars, and galaxies. The black background is indicative of the mysteries of dark-energy and dark-matter. The new instruments to be installed on HST during this mission, Wide Field Camera-3 and the Cosmic Origins Spectrograph, will make observations to help understand these unseen components which seem to dominate the structure of the Universe. The red border of the patch represents the red-shifted glow of the early Universe, and the limit of the Hubble's view into the cosmos. Upon completion of STS-125, the fifth mission to service HST, the Hubble will provide even deeper and more detailed views of the Universe. Soaring by the telescope is the space shuttle which initially deployed Hubble and has enabled astronauts to continually upgrade the telescope, significantly contributing to the expansion of human knowledge. The NASA insignia design for space shuttle flights is reserved for use by the astronauts and for other official use as the NASA Administrator may authorize. Public availability has been approved only in the forms of illustrations by the various news media. When and if there is any change in this policy, which is not anticipated, the change will be publicly announced. Photo credit: NASA STS125-S-001

The tank will be attached to the twin solid rocket boosters on Aug. 3 for the STS-125 mission, the fifth and final shuttle servicing mission to NASA’s Hubble Space Telescope. During the mission, the crew will install new instruments on the telescope, including the Cosmic Origins Spectrograph and the Wide Field Camera 3. A refurbished Fine Guidance Sensor will replace one unit of three now onboard. Mission specialists will also install new gyroscopes, batteries and thermal blankets on the telescope. Launch is targeted for Oct. 8. Photo credit: NASA/Jim Grossmann KSC-08pd2156

CAPE CANAVERAL, Fla. – In the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center, technicians check the placement of an overhead crane to the Wide Field Camera 3, or WFC3, that will transfer the WFC3 to the Super Lightweight Interchangeable Carrier. WFC3 is part of the payload on space shuttle Atlantis' STS-125 mission for the fifth and final Hubble servicing flight to NASA's Hubble Space Telescope. As Hubble enters the last stage of its life, WFC3 will be Hubble's next evolutionary step, allowing Hubble to peer ever further into the mysteries of the cosmos. WFC3 will study a diverse range of objects and phenomena, from young and extremely distant galaxies, to much more nearby stellar systems, to objects within our very own solar system. WFC3 will take the place of Wide Field Planetary Camera 2, which astronauts will bring back to Earth aboard the shuttle. Launch of Atlantis is targeted at 1:34 a.m. EDT Oct. 8.

CAPE CANAVERAL, Fla. – STS-125 crew members conduct equipment and procedure familiarization on parts of the payload in the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center in Florida in preparation for their mission to service NASA's Hubble Space Telescope. Space shuttle Atlantis' 11-day flight is targeted for launch May 12 and will include five spacewalks to refurbish and upgrade the telescope with state-of-the-art science instruments. The payload includes a Wide Field Camera 3, fine guidance sensor and the Cosmic Origins Spectrograph. As a result, Hubble's capabilities will be expanded and its operational lifespan extended through at least 2014. Photo credit: NASA/Kim Shiflett KSC-2009-2512
