KENNEDY SPACE CENTER, Fla. -- The orbiter drag chute deploys after the Space Shuttle orbiter Atlantis lands on Runway 15 of the KSC Shuttle Landing Facility (SLF) at the conclusion of the nearly 11-day STS-86 mission. Main gear touchdown was at 5:55:09 p.m. EDT, Oct. 6, 1997, with an unofficial mission-elapsed time of 10 days, 19 hours, 20 minutes and 50 seconds. The first two KSC landing opportunities on Sunday were waved off because of weather concerns. The 87th Space Shuttle mission was the 40th landing of the Shuttle at KSC. On Sunday evening, the Space Shuttle program reached a milestone: The total flight time of the Shuttle passed the two-year mark. STS86 was the seventh of nine planned dockings of the Space Shuttle with the Russian Space Station Mir. STS-86 Mission Specialist David A. Wolf replaced NASA astronaut and Mir 24 crew member C. Michael Foale, who has been on the Mir since mid-May. Foale returned to Earth on Atlantis with the remainder of the STS-86 crew. The other crew members are Commander James D. Wetherbee, Pilot Michael J. Bloomfield, and Mission Specialists Wendy B. Lawrence, Scott E. Parazynski, Vladimir Georgievich Titov of the Russian Space Agency, and Jean-Loup J.M. Chretien of the French Space Agency, CNES. Wolf is scheduled to remain on the Mir until the STS-89 Shuttle mission in January. Besides the docking and crew exchange, STS-86 included the transfer of more than three-and-a-half tons of science/logistical equipment and supplies between the two orbiting spacecraft. Parazynski and Titov also conducted a spacewalk while Atlantis and the Mir were docked KSC-97PC1497

KENNEDY SPACE CENTER, FLA. - On Launch Complex 17-A, Cape Canaveral Air Force Station, the Boeing Delta II rocket and its Mars Exploration Rover (MER-A) payload are free of the tower and ready for launch. This will be the third launch attempt in as many days after weather concerns postponed the launches June 8 and June 9. MER-A is the first of two rovers being launched to Mars. When the two rovers arrive at the red planet in 2004, they will bounce to airbag-cushioned landings at sites offering a balance of favorable conditions for safe landings and interesting science. The rovers see sharper images, can explore farther and examine rocks better than anything that has ever landed on Mars. The designated site for MER-A mission is Gusev Crater, which appears to have been a crater lake. The second rover, MER-B, is scheduled to launch June 25.

KENNEDY SPACE CENTER, FLA. — From among four lightning masts surrounding the launch pad, NASA’s New Horizons spacecraft lifts off the launch pad aboard an Atlas V rocket spewing flames and smoke. Liftoff was on time at 2 p.m. EST from Complex 41 on Cape Canaveral Air Force Station in Florida. This was the third launch attempt in as many days after scrubs due to weather concerns. The compact, 1,050-pound piano-sized probe will get a boost from a kick-stage solid propellant motor for its journey to Pluto. New Horizons will be the fastest spacecraft ever launched, reaching lunar orbit distance in just nine hours and passing Jupiter 13 months later. The New Horizons science payload, developed under direction of Southwest Research Institute, includes imaging infrared and ultraviolet spectrometers, a multi-color camera, a long-range telescopic camera, two particle spectrometers, a space-dust detector and a radio science experiment. The dust counter was designed and built by students at the University of Colorado, Boulder. The launch at this time allows New Horizons to fly past Jupiter in early 2007 and use the planet’s gravity as a slingshot toward Pluto. The Jupiter flyby trims the trip to Pluto by as many as five years and provides opportunities to test the spacecraft’s instruments and flyby capabilities on the Jupiter system. New Horizons could reach the Pluto system as early as mid-2015, conducting a five-month-long study possible only from the close-up vantage of a spacecraft. KSC-06pd0099

CAPE CANAVERAL, Fla. – As clouds begin to gather over the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida, the convoy command and SCAPE vehicles are in position in the event of a return-to-landing-site is needed after launch of space shuttle Endeavour on the STS-127 mission. NASA managers postponed today’s space shuttle launch because of lightning and thunderstorms within the 20-nautical-mile circle around the launch pad. The fifth launch attempt for the STS-127 mission was scrubbed at 6:39 p.m. EDT. The first two launch attempts on June 13 and June 17 were scrubbed when a hydrogen gas leak occurred during tanking due to a misaligned Ground Umbilical Carrier Plate. Mission managers also decided to delay tanking on July 11 for a launch attempt later in the day to allow engineers and safety personnel time to analyze data captured during lightning strikes near the pad on July 10. The fourth attempt on July 12 was scrubbed due to weather concerns as well. Photo credit: NASA/Chuck Tintera KSC-2009-4047

CAPE CANAVERAL, Fla. – Ominous clouds roll toward Launch Pad 39A at NASA's Kennedy Space Center in Florida. NASA managers postponed today’s space shuttle launch because of lightning and thunderstorms within the 20-nautical-mile circle around the launch pad. The fifth launch attempt for the STS-127 mission was scrubbed at 6:39 p.m. EDT. The first two launch attempts on June 13 and June 17 were scrubbed when a hydrogen gas leak occurred during tanking due to a misaligned Ground Umbilical Carrier Plate. Mission managers also decided to delay tanking on July 11 for a launch attempt later in the day to allow engineers and safety personnel time to analyze data captured during lightning strikes near the pad on July 10. Weather concerns caused a scrub July 12 as well. Endeavour will deliver the Japanese Experiment Module's Exposed Facility, or JEM-EF, and the Experiment Logistics Module-Exposed Section, or ELM-ES, in the final of three flights dedicated to the assembly of the Japan Aerospace Exploration Agency's Kibo laboratory complex on the International Space Station. STS-127 is the 29th flight for the assembly of the space. Photo credit: NASA/Tim Jacobs KSC-2009-4012

KENNEDY SPACE CENTER, FLA. — Great white egrets and a great blue heron in the foreground seem to stand watch as NASA’s New Horizons spacecraft leaps off the pad on time at 2 p.m. EST aboard an Atlas V rocket from Complex 41 on Cape Canaveral Air Force Station in Florida. This was the third launch attempt in as many days after scrubs due to weather concerns. The compact, 1,050-pound piano-sized probe will get a boost from a kick-stage solid propellant motor for its journey to Pluto. New Horizons will be the fastest spacecraft ever launched, reaching lunar orbit distance in just nine hours and passing Jupiter 13 months later. The New Horizons science payload, developed under direction of Southwest Research Institute, includes imaging infrared and ultraviolet spectrometers, a multi-color camera, a long-range telescopic camera, two particle spectrometers, a space-dust detector and a radio science experiment. The dust counter was designed and built by students at the University of Colorado, Boulder. The launch at this time allows New Horizons to fly past Jupiter in early 2007 and use the planet’s gravity as a slingshot toward Pluto. The Jupiter flyby trims the trip to Pluto by as many as five years and provides opportunities to test the spacecraft’s instruments and flyby capabilities on the Jupiter system. New Horizons could reach the Pluto system as early as mid-2015, conducting a five-month-long study possible only from the close-up vantage of a spacecraft.

EDWARDS, Calif. – On Edwards Air Force Base in California, space shuttle Endeavour undergoes recovery operations after its landing. The orbiter convoy normally begins recovery operations in earnest about two hours before the shuttle is scheduled to land. Specially designed vehicles or units and a team of trained personnel “safe” the orbiter and prepare it for towing. Purge and Coolant Umbilical Access Vehicles are moved into position behind the orbiter to get access to the umbilical areas. The flight crew is replaced aboard the orbiter by exchange sup¬port personnel who prepare the orbiter for ground tow operations, install switch guards and remove data packages from any onboard experiments. After a total safety downgrade, vehicle ground personnel make numerous preparations for the towing operation, including install¬ing landing gear lock pins, disconnecting the nose landing gear drag link, positioning the towing vehicle in front of the orbiter and connecting the tow bar. The decision to land Endeavour at Edwards was made due to weather concerns at NASA's Kennedy Space Center in Florida. In the 52nd landing at Edwards, Endeavour touched down at 4:25 p.m. EST to end the STS-126 mission, completing its 16-day journey of more than 6.6 million miles in space. Endeavour will be returned to Kennedy atop a Shuttle Carrier Aircraft, or SCA, a modified Boeing 747 jetliner. Photo credit: NASA/Tony Landis, VAFB KSC-08pd3885

KENNEDY SPACE CENTER, FLA. - On Launch Complex 17-A, Cape Canaveral Air Force Station, the Boeing Delta II rocket and its Mars Exploration Rover (MER-A) payload are free of the tower and ready for launch. This will be the third launch attempt in as many days after weather concerns postponed the launches June 8 and June 9. MER-A is the first of two rovers being launched to Mars. When the two rovers arrive at Mars in 2004, they will bounce to airbag-cushioned landings at sites offering a balance of favorable conditions for safe landings and interesting science. The rovers see sharper images, can explore farther and examine rocks better than anything that has ever landed on Mars. The designated site for MER-A mission is Gusev Crater, which appears to have been a crater lake. The second rover, MER-B, is scheduled to launch June 25.

KENNEDY SPACE CENTER, FLA. — Into a blue, cloud-scattered sky, NASA’s New Horizons spacecraft lifts off on time at 2 p.m. EST aboard an Atlas V rocket from Complex 41 on Cape Canaveral Air Force Station in Florida This was the third launch attempt in as many days after scrubs due to weather concerns. The compact, 1,050-pound piano-sized probe will get a boost from a kick-stage solid propellant motor for its journey to Pluto. New Horizons will be the fastest spacecraft ever launched, reaching lunar orbit distance in just nine hours and passing Jupiter 13 months later. The New Horizons science payload, developed under direction of Southwest Research Institute, includes imaging infrared and ultraviolet spectrometers, a multi-color camera, a long-range telescopic camera, two particle spectrometers, a space-dust detector and a radio science experiment. The dust counter was designed and built by students at the University of Colorado, Boulder. The launch at this time allows New Horizons to fly past Jupiter in early 2007 and use the planet’s gravity as a slingshot toward Pluto. The Jupiter flyby trims the trip to Pluto by as many as five years and provides opportunities to test the spacecraft’s instruments and flyby capabilities on the Jupiter system. New Horizons could reach the Pluto system as early as mid-2015, conducting a five-month-long study possible only from the close-up vantage of a spacecraft.

KENNEDY SPACE CENTER, Fla. -- The orbiter drag chute deploys after the Space Shuttle orbiter Atlantis lands on Runway 15 of the KSC Shuttle Landing Facility (SLF) at the conclusion of the nearly 11-day STS-86 mission. The Vehicle Assembly Building (VAB) can be seen in the background. Main gear touchdown was at 5:55:09 p.m. EDT, Oct. 6, 1997, with an unofficial mission-elapsed time of 10 days, 19 hours, 20 minutes and 50 seconds. The first two KSC landing opportunities on Sunday were waved off because of weather concerns. The 87th Space Shuttle mission was the 40th landing of the Shuttle at KSC. On Sunday evening, the Space Shuttle program reached a milestone: The total flight time of the Shuttle passed the two-year mark. STS86 was the seventh of nine planned dockings of the Space Shuttle with the Russian Space Station Mir. STS-86 Mission Specialist David A. Wolf replaced NASA astronaut and Mir 24 crew member C. Michael Foale, who has been on the Mir since mid-May. Foale returned to Earth on Atlantis with the remainder of the STS-86 crew. The other crew members are Commander James D. Wetherbee, Pilot Michael J. Bloomfield, and Mission Specialists Wendy B. Lawrence, Scott E. Parazynski, Vladimir Georgievich Titov of the Russian Space Agency, and Jean-Loup J.M. Chretien of the French Space Agency, CNES. Wolf is scheduled to remain on the Mir until the STS-89 Shuttle mission in January. Besides the docking and crew exchange, STS-86 included the transfer of more than three-and-a-half tons of science/logistical equipment and supplies between the two orbiting spacecraft. Parazynski and Titov also conducted a spacewalk while Atlantis and the Mir were docked KSC-97PC1498

EDWARDS, Calif. – Against a setting sun, space shuttle Endeavour undergoes recovery operations on Edwards Air Force Base in California after its landing. The orbiter convoy normally begins recovery operations in earnest about two hours before the shuttle is scheduled to land. Specially designed vehicles or units and a team of trained personnel “safe” the orbiter and prepare it for towing. Purge and Coolant Umbilical Access Vehicles are moved into position behind the orbiter to get access to the umbilical areas. The flight crew is replaced aboard the orbiter by exchange sup¬port personnel who prepare the orbiter for ground tow operations, install switch guards and remove data packages from any onboard experiments. After a total safety downgrade, vehicle ground personnel make numerous preparations for the towing operation, including install¬ing landing gear lock pins, disconnecting the nose landing gear drag link, positioning the towing vehicle in front of the orbiter and connecting the tow bar. The decision to land Endeavour at Edwards was made due to weather concerns at NASA's Kennedy Space Center in Florida. In the 52nd landing at Edwards, Endeavour touched down at 4:25 p.m. EST to end the STS-126 mission, completing its 16-day journey of more than 6.6 million miles in space.

CAPE CANAVERAL, Fla. – The darkened sky over Launch Pad 39A at NASA's Kennedy Space Center in Florida reveal the decision to postpone today’s space shuttle launch because of lightning and thunderstorms within the 20-nautical-mile circle around the launch pad. The fifth launch attempt for the STS-127 mission was scrubbed at 6:39 p.m. EDT. This was the fifth launch attempt for the STS-127 mission. The first two launch attempts on June 13 and June 17 were scrubbed when a hydrogen gas leak occurred during tanking due to a misaligned Ground Umbilical Carrier Plate. Mission managers also decided to delay tanking on July 11 for a launch attempt later in the day to allow engineers and safety personnel time to analyze data captured during lightning strikes near the pad on July 10. The fourth attempt on July 12 was scrubbed due to weather concerns as well. Photo courtesy of Scott Andrews KSC-2009-4045

KENNEDY SPACE CENTER, FLA. — NASA’s New Horizons spacecraft emerges from a cloud painted pink by the Atlas V rocket roaring through it after launch from Complex 41 on Cape Canaveral Air Force Station in Florida. Liftoff was on time at 2 p.m. EST. This was the third launch attempt in as many days after scrubs due to weather concerns. The compact, 1,050-pound piano-sized probe will get a boost from a kick-stage solid propellant motor for its journey to Pluto. New Horizons will be the fastest spacecraft ever launched, reaching lunar orbit distance in just nine hours and passing Jupiter 13 months later. The New Horizons science payload, developed under direction of Southwest Research Institute, includes imaging infrared and ultraviolet spectrometers, a multi-color camera, a long-range telescopic camera, two particle spectrometers, a space-dust detector and a radio science experiment. The dust counter was designed and built by students at the University of Colorado, Boulder. The launch at this time allows New Horizons to fly past Jupiter in early 2007 and use the planet’s gravity as a slingshot toward Pluto. The Jupiter flyby trims the trip to Pluto by as many as five years and provides opportunities to test the spacecraft’s instruments and flyby capabilities on the Jupiter system. New Horizons could reach the Pluto system as early as mid-2015, conducting a five-month-long study possible only from the close-up vantage of a spacecraft.

KENNEDY SPACE CENTER, FLA. — From between lightning masts surrounding the launch pad, NASA’s New Horizons spacecraft roars into the blue sky aboard an Atlas V rocket spewing flames and smoke. Liftoff was on time at 2 p.m. EST from Complex 41 on Cape Canaveral Air Force Station in Florida. This was the third launch attempt in as many days after scrubs due to weather concerns. The compact, 1,050-pound piano-sized probe will get a boost from a kick-stage solid propellant motor for its journey to Pluto. New Horizons will be the fastest spacecraft ever launched, reaching lunar orbit distance in just nine hours and passing Jupiter 13 months later. The New Horizons science payload, developed under direction of Southwest Research Institute, includes imaging infrared and ultraviolet spectrometers, a multi-color camera, a long-range telescopic camera, two particle spectrometers, a space-dust detector and a radio science experiment.

KENNEDY SPACE CENTER, FLA. - On Launch Complex 17-A, Cape Canaveral Air Force Station, the Boeing Delta II rocket and its Mars Exploration Rover (MER-A) payload are free of the tower (right) and ready for launch. This will be the third launch attempt in as many days after weather concerns postponed the launches June 8 and June 9. MER-A is the first of two rovers being launched to Mars. When the two rovers arrive at Mars in 2004, they will bounce to airbag-cushioned landings at sites offering a balance of favorable conditions for safe landings and interesting science. The rovers see sharper images, can explore farther and examine rocks better than anything that has ever landed on Mars. The designated site for MER-A mission is Gusev Crater, which appears to have been a crater lake. The second rover, MER-B, is scheduled to launch June 25.

EDWARDS, Calif. – Against a setting sun, space shuttle Endeavour undergoes recovery operations on Edwards Air Force Base in California after its landing. The orbiter convoy normally begins recovery operations in earnest about two hours before the shuttle is scheduled to land. Specially designed vehicles or units and a team of trained personnel “safe” the orbiter and prepare it for towing. Purge and Coolant Umbilical Access Vehicles are moved into position behind the orbiter to get access to the umbilical areas. The flight crew is replaced aboard the orbiter by exchange sup¬port personnel who prepare the orbiter for ground tow operations, install switch guards and remove data packages from any onboard experiments. After a total safety downgrade, vehicle ground personnel make numerous preparations for the towing operation, including install¬ing landing gear lock pins, disconnecting the nose landing gear drag link, positioning the towing vehicle in front of the orbiter and connecting the tow bar. The decision to land Endeavour at Edwards was made due to weather concerns at NASA's Kennedy Space Center in Florida. In the 52nd landing at Edwards, Endeavour touched down at 4:25 p.m. EST to end the STS-126 mission, completing its 16-day journey of more than 6.6 million miles in space. Endeavour will be returned to Kennedy atop a Shuttle Carrier Aircraft, or SCA, a modified Boeing 747 jetliner. Photo credit: NASA/Tony Landis, VAFB KSC-08pd3887
