KENNEDY SPACE CENTER, FLA. - STS-114 Mission Specialist Stephen Robinson is helped by the Closeout Crew with his launch and entry suit before entering Space Shuttle Discovery. The Return to Flight mission to the International Space Station carries the External Stowage Platform-2, equipped with spare part assemblies, and a replacement Control Moment Gyroscope contained in the Lightweight Multi-Purpose Experiment Support Structure and Multi-Purpose Logistics Module Raffaello, housing 15 tons of hardware and supplies that will be transferred to the Station after the Shuttle docks to the complex . On this mission, the crew will perform inspections on-orbit for the first time of all of the Reinforced Carbon-Carbon (RCC) panels on the leading edge of the wings and the Thermal Protection System tiles using the new Canadian-built Orbiter Boom Sensor System and the data from 176 impact and temperature sensors. Mission Specialists will also practice repair techniques on RCC and tile samples during a spacewalk in the payload bay. KSC-05pp1799

CAPE CANAVERAL, Fla. – A closeup of the wing leading edge on space shuttle Atlantis where a reinforced-carbon carbon, or RCC, panel has been removed. The structural edge of the wing (area of red and green behind the panels) will undergo spar corrosion inspection to verify the structural integrity of the wing. The RCC panels will be placed in protective coverings until the inspection is complete. Atlantis will make the 31st flight to the International Space Station for the STS-129 mission, targeted for launch on Nov. 12. Photo credit: NASA/Tim Jacobs KSC-2009-3832

KENNEDY SPACE CENTER, FLA. - Viewed from a camera in the midst of Florida greenery across the marshy water, Space Shuttle Discovery leaps through billows of smoke and steam on Launch Pad 39B on the historic Return to Flight mission STS-114. Liftoff occurred at 10:39 a.m. EDT. This is the 114th Space Shuttle flight and the 31st for Discovery. The 12-day mission is expected to end with touchdown at the Shuttle Landing Facility on Aug. 7. On this mission to the International Space Station the crew will perform inspections on-orbit for the first time of all of the Reinforced Carbon-Carbon (RCC) panels on the leading edge of the wings and the Thermal Protection System tiles using the new Canadian-built Orbiter Boom Sensor System and the data from 176 impact and temperature sensors. Mission Specialists will also practice repair techniques on RCC and tile samples during a spacewalk in the payload bay. During two additional spacewalks, the crew will install the External Stowage Platform-2, equipped with spare part assemblies, and a replacement Control Moment Gyroscope contained in the Lightweight Multi-Purpose Experiment Support Structure.

KENNEDY SPACE CENTER, FLA. - In the Orbiter Processing Facility (OPF), a United Space Alliance technician examines the attachment points for the spars on the exterior of a wing of Space Shuttle Atlantis. Reinforced Carbon Carbon (RCC) panels are mechanically attached to the wing with a series of floating joints - spars - to reduce loading on the panels caused by wing deflections. The aluminum and the metallic attachments are protected from exceeding temperature limits by internal insulation. The next launch of Atlantis will be on mission STS-114, a utilization and logistics flight to the International Space Station.

KENNEDY SPACE CENTER, FLA. - STS-114 Pilot James Kelly is helped by the Closeout Crew with his launch and entry suit before entering Space Shuttle Discovery.The Return to Flight mission to the International Space Station carries the External Stowage Platform-2, equipped with spare part assemblies, and a replacement Control Moment Gyroscope contained in the Lightweight Multi-Purpose Experiment Support Structure and Multi-Purpose Logistics Module Raffaello, housing 15 tons of hardware and supplies that will be transferred to the Station after the Shuttle docks to the complex . On this mission, the crew will perform inspections on-orbit for the first time of all of the Reinforced Carbon-Carbon (RCC) panels on the leading edge of the wings and the Thermal Protection System tiles using the new Canadian-built Orbiter Boom Sensor System and the data from 176 impact and temperature sensors. Mission Specialists will also practice repair techniques on RCC and tile samples during a spacewalk in the payload bay. KSC-05pp1795

KENNEDY SPACE CENTER, FLA. - Jim Landy, NDE specialist with USA, looks closely at an area of a Reinforced Carbon Carbon panel just examined using flash thermography. A relatively new procedure at KSC, thermography uses high intensity light to heat areas of the panels. The panels are then immediately scanned with an infrared camera. As the panels cool, any internal flaws are revealed. The gray carbon composite RCC panels are attached to the leading edge of the wing of the orbiters. They have sufficient strength to withstand the aerodynamic forces experienced during launch and reentry, which can reach as high as 800 pounds per square foot. The operating range of RCC is from minus 250º F to about 3,000º F, the temperature produced by friction with the atmosphere during reentry. The panels will be installed on the orbiter Discovery, designated for the first Return to Flight mission, STS-114. KSC-04pd0450

KENNEDY SPACE CENTER, FLA. - Workers in the Orbiter Processing Facility prepare the Reinforced Carbon-Carbon (RCC) chin panel to install on Discovery. The chin panel is the smile-shaped section of RCC directly below the nose cap that provides a thermal barrier during re-entry. The nose cap, with chin panel, was removed from the vehicle in the summer of 2003 and returned to the vendor, where it underwent numerous forms of Non-Destructive Evaluation. These tests included X-ray, ultrasound and eddy current to ensure its structural integrity prior to reinstallation. Discovery is designated as the Return to Flight vehicle for mission STS-114, no earlier than March 2005. KSC-04pd1423

KENNEDY SPACE CENTER, FLA. - Clouds of smoke and steam fill Launch Pad 39B as Space Shuttle Discovery roars into the sky on the historic Return to Flight mission STS-114. Liftoff occurred at 10:39 a.m. EDT. It is the 114th Space Shuttle flight and the 31st for Discovery. The 12-day mission is expected to end with touchdown at the Shuttle Landing Facility on Aug. 7. On this mission to the International Space Station the crew will perform inspections on-orbit for the first time of all of the Reinforced Carbon-Carbon (RCC) panels on the leading edge of the wings and the Thermal Protection System tiles using the new Canadian-built Orbiter Boom Sensor System and the data from 176 impact and temperature sensors. Mission Specialists will also practice repair techniques on RCC and tile samples during a spacewalk in the payload bay. During two additional spacewalks, the crew will install the External Stowage Platform-2, equipped with spare part assemblies, and a replacement Control Moment Gyroscope contained in the Lightweight Multi-Purpose Experiment Support Structure.

KENNEDY SPACE CENTER, FLA. - In the Orbiter Processing Facility (OPF), United Space Alliance technicians replace the attachment points for the spars on the interior of a wing of Space Shuttle Atlantis. Reinforced Carbon Carbon (RCC) panels are mechanically attached to the wing with a series of floating joints - spars - to reduce loading on the panels caused by wing deflections. The aluminum and the metallic attachments are protected from exceeding temperature limits by internal insulation. The next launch of Atlantis will be on mission STS-114, a utilization and logistics flight to the International Space Station.

KENNEDY SPACE CENTER, FLA. - As billows of smoke and steam roll away, Space Shuttle Discovery leaps from Launch Pad 39B on the historic Return to Flight mission STS-114. Liftoff occurred at 10:39 a.m. EDT. At right is the 290-foot water tower that holds the 300,000 gallons of water that flood the pad for sound suppression. This is the 114th Space Shuttle flight and the 31st for Discovery. The 12-day mission is expected to end with touchdown at the Shuttle Landing Facility on Aug. 7.
