CAPE CANAVERAL, Fla. – In the clean room of the Payload Hazardous Processing Facility at NASA's Kennedy Space Center, a worker from NASA's Goddard Space Flight Center uses black light inspection for a thorough cleaning of the Cosmic Origins Spectrograph, or COS. Black light inspection uses UVA fluorescence to detect possible particulate microcontamination, minute cracks or fluid leaks. The COS will be installed on the Hubble Space Telescope on space shuttle Atlantis' STS-125 mission. COS will be the most sensitive ultraviolet spectrograph ever flown on Hubble and will probe the "cosmic web" - the large-scale structure of the universe whose form is determined by the gravity of dark matter and is traced by galaxies and intergalactic gas. The COS far-ultraviolet channel has a sensitivity 30 times greater than that of previous spectroscopic instruments for the detection of extremely low light levels. Launch of Atlantis on the STS-125 mission is targeted for Oct. 8. Photo credit: NASA/Kim Shiflett KSC-08pd2325

Hall of Fame astronauts and visitors gathered to honor 2011 inductees Karol "Bo" Bobko and Susan Helms. During his 19 years in the astronaut program, Bobko flew on three space shuttle missions and logged more than 386 hours in space. He served as pilot during the first voyage of space shuttle Challenger aboard STS-6 in April 1983 and as commander during the maiden flight of space shuttle Atlantis aboard STS-51J in October 1985. Helms, a five-time space shuttle astronaut, has logged 5,064 hours in space. During her stay onboard the International Space Station as a member of the Expedition-2 crew in 2001, Helms performed a world record 8 hour and 56 minute spacewalk. Bobko and Helms join the ranks of the U.S. Astronaut Hall of Fame bringing the number of space explorers enshrined in the Hall of Fame to 79. Photo Credit: NASA/Jim Grossmann KSC-2011-3401

CAPE CANAVERAL, Fla. -- In the Space Shuttle Main Engine Processing Facility at NASA's Kennedy Space Center in Florida, two of six space shuttle main engines are prepared for the STS-134 and STS-335 missions. Postflight inspections and maintenance of each engine are conducted in the facility between shuttle missions by Pratt & Whitney Rocketdyne aerospace technicians. Three main engines are clustered at the aft end of the shuttle and have a combined thrust of more than 1.2 million pounds. Each engine utilizes liquid hydrogen for fuel and liquid oxygen as oxidizer and operates during the entire eight-and-a-half minute ride to orbit. Space shuttle Endeavour's STS-134 mission is the final planned mission of the Space Shuttle Program and will deliver the Alpha Magnetic Spectrometer, as well as critical spare components, to the International Space Station next year. Shuttle Atlantis will be prepared for STS-335, which is the planned "launch on need," or potential rescue mission, for Endeavour's STS-134 mission. For information, visit www.nasa.gov/shuttle.

Range : 280,000 km. ( 170,000 miles ) P-34726 BW Two 10 minute exposures of Neptune's rings clearly show the two main rings , as well as the inner faint ring and the faint band that extends planetward from roughly halfway between the two bright rings. Both bright rings have material throughout their entire orbit, and are therefore continuous. The inner ring and the broad band are much fainter than the two narrow main rings. These images were taken 1 hour and 27 minutes aprt, using the clear filter on Voyager 2's wide angle camera. These long exposures images were taken while the rings were backlit by the sun. This viewing geometry enhances the visibility of dust and allows optically thinner parts of the rings to be seen. The bright glare in the center is due to overexposure of the crescent of Neptune . The two gaps in the upper part of the outer ring in the image on the left are due to the removal of blemishes during computer processing of the images. Numerous bright stars are evident in the background. ARC-1989-A89-7045

KENNEDY SPACE CENTER, Fla. -- After a 24-hour delay of the STS-105 launch, Commander Scott Horowitz is the first off the Astrovan returning the crews to the Operations and Checkout Building. Behind him is Mission Specialist Daniel Barry. Launch countdown activities for the 12-day mission were called off at about 5:12 p.m. Aug. 9 during the T-9 minute hold due to the high potential for lightning, a thick cloud cover and the potential for showers. These were clear violations of launch weather criteria. The next launch attempt will be on Friday, Aug. 10, at the preferred launch time of about 5:15 p.m. The launch window extends for about 5 minutes. On the mission, Space Shuttle Discovery will be transporting the Expedition Three crew and several scientific experiments and payloads to the International Space Station, including the Early Ammonia Servicer (EAS) tank. The EAS, which will support the thermal control subsystems until a permanent system is activated, will be attached to the Station during two spacewalks. The three-member Expedition Two crew will be returning to Earth aboard Discovery after a five-month stay on the Station KSC-01pp1451

Part of the payload is the Early Ammonia Servicer (EAS) tank, which will be attached to the Station during the spacewalks. The EAS contains spare ammonia for the Station’s cooling system. The three-member Expedition Two crew will be returning to Earth aboard Discovery after a five-month stay on the Station. [Photo by Scott Andrews; Nikon D1X camera KSC01padig271

KENNEDY SPACE CENTER, FLA. -- The space shuttle Atlantis STS-122 crew receives instruction on slidewire basket operation, part of the emergency exit system on the fixed service structure on Launch Pad 39A. Standing, from left, are Mission Specialists Stanley Love; Leopold Eyharts' backup, Frank De Winne; and Pilot Alan Poindexter. Standing in the basket, from left, are Mission Specialists Hans Schlegel, Leland Melvin and Rex Walheim. Schlegel, Eyharts and De Winne are with the European Space Agency. Eyharts will remain on the International Space Station as a flight engineer for Expedition 16 following the STS-122 mission. Seven slidewire baskets are available to carry the crew from the level of the pad's Orbiter Access Arm to a safe landing site below, if needed. Each basket can hold up to three people. A braking system catch net and drag chain slow, and then halt, the baskets as they travel down the wire at approximately 55 miles per hour. The journey takes about half a minute. A bunker is located in the landing zone 1,200 feet west of the pad, with an M-113 armored personnel carrier stationed nearby. The STS-122 crew is at NASA's Kennedy Space Center to take part in terminal countdown demonstration test, or TCDT, activities, a standard part of launch preparations. The TCDT provides astronauts and ground crews with equipment familiarization and a simulated launch countdown before launch. On mission STS-122, Atlantis will deliver the European Space Agency's Columbus module to the International Space Station. Columbus is a multifunctional, pressurized laboratory that will be permanently attached to U.S. Node 2, called Harmony, and will expand the research facilities aboard the station. Launch is targeted for Dec. 6. Photo credit: NASA/Kim Shiflett KSC-07pd3387

Seven slidewire baskets are available to carry the crew from the level of the pad's Orbiter Access Arm to a safe landing site below, if needed. Each basket can hold up to three people. A braking system catch net and drag chain slow, and then halt, the baskets as they travel down the wire at approximately 55 miles per hour. The journey takes about half a minute. A bunker is located in the landing zone 1,200 feet west of the pad, with an M-113 armored personnel carrier stationed nearby. The STS-122 crew is at NASA's Kennedy Space Center to take part in terminal countdown demonstration test, or TCDT, activities, a standard part of launch preparations. The TCDT provides astronauts and ground crews with equipment familiarization and a simulated launch countdown before launch. On mission STS-122, Atlantis will deliver the European Space Agency's Columbus module to the International Space Station. Columbus is a multifunctional, pressurized laboratory that will be permanently attached to U.S. Node 2, called Harmony, and will expand the research facilities aboard the station. Launch is targeted for Dec. 6. Photo credit: NASA/Kim Shiflett KSC-07pd3386

CAPE CANAVERAL, Fla. – In the clean room of the Payload Hazardous Processing Facility at NASA's Kennedy Space Center, a worker from NASA's Goddard Space Flight Center uses black light inspection for a thorough cleaning of the Cosmic Origins Spectrograph, or COS. Black light inspection uses UVA fluorescence to detect possible particulate microcontamination, minute cracks or fluid leaks. The COS will be installed on the Hubble Space Telescope on space shuttle Atlantis' STS-125 mission. COS will be the most sensitive ultraviolet spectrograph ever flown on Hubble and will probe the "cosmic web" - the large-scale structure of the universe whose form is determined by the gravity of dark matter and is traced by galaxies and intergalactic gas. The COS far-ultraviolet channel has a sensitivity 30 times greater than that of previous spectroscopic instruments for the detection of extremely low light levels.

CAPE CANAVERAL, Fla. -- In the Space Shuttle Main Engine Processing Facility at NASA's Kennedy Space Center in Florida, one of six space shuttle main engines is prepared for the STS-134 and STS-335 missions. Postflight inspections and maintenance of each engine are conducted in the facility between shuttle missions by Pratt & Whitney Rocketdyne aerospace technicians. Three main engines are clustered at the aft end of the shuttle and have a combined thrust of more than 1.2 million pounds. Each engine utilizes liquid hydrogen for fuel and liquid oxygen as oxidizer and operates during the entire eight-and-a-half minute ride to orbit. Space shuttle Endeavour's STS-134 mission is the final planned mission of the Space Shuttle Program and will deliver the Alpha Magnetic Spectrometer, as well as critical spare components, to the International Space Station next year. Shuttle Atlantis will be prepared for STS-335, which is the planned "launch on need," or potential rescue mission, for Endeavour's STS-134 mission. For information, visit www.nasa.gov/shuttle.

Three main engines are clustered at the aft end of the shuttle and have a combined thrust of more than 1.2 million pounds. Each engine utilizes liquid hydrogen for fuel and liquid oxygen as oxidizer and operates during the entire eight-and-a-half minute ride to orbit. Space shuttle Endeavour's STS-134 mission is the final planned mission of the Space Shuttle Program and will deliver the Alpha Magnetic Spectrometer, as well as critical spare components, to the International Space Station next year. Shuttle Atlantis will be prepared for STS-335, which is the planned "launch on need," or potential rescue mission, for Endeavour's STS-134 mission. For information, visit www.nasa.gov/shuttle.
