PITOT STATIC PRESSURE PROBE CALIBRATION FOR BF GOODRICH AEROSPACE

KENNEDY SPACE CENTER, FLA. -- In bay 3 of the Orbiter Processing Facility, B.F. Goodrich technician David Cobb checks the hydraulic seal he replaced in space shuttle Discovery's right main-gear strut. Engineers determined an observed leak of hydraulic fluid in the main landing gear strut exceeded specification and could not be reduced to an acceptable rate. Thus, the leaky seal and three other seals were replaced. Prior to discovery of the leak, the vehicle had been scheduled to roll over Sept. 19 from the OPF to the Vehicle Assembly Building. A new rollover date will be set for Discovery, which is targeted for launch on Oct. 23. Photo credit: NASA/George Shelton

KENNEDY SPACE CENTER, FLA. -- This photo shows the leaking hydraulic seal in space shuttle Discovery's right main-gear strut. United Space Alliance and B.F. Goodrich technicians are working to replace the seal. The struts act as shock absorbers during the shuttle's landing. Engineers determined the observed leak of hydraulic fluid in the main landing gear strut exceeded specification and could not be reduced to an acceptable rate. Removing the strut and replacing seals require disconnecting and replacing the brakes and tires, disconnecting and reconnecting instruments and other requirements to allow access to the strut. Discovery had been scheduled to roll over Sept. 19 from its processing hangar to the Vehicle Assembly Building. A new rollover date will be set after technicians determine how long replacing the seal will take. Photo credit: NASA/George Shelton

History of Chandra X-Ray Observatory

Leon Van Speybroeck of the Harvard-Smithsonian Center for Astrophysics in Cambridge Massachusetts was awarded the 2002 Bruno Rossi Prize of the High-Energy Astrophysics Division of the American Astronomy Society. The Rossi Prize is an arnual recognition of significant contributions in high-energy astrophysics in honor of the Massachusetts Institute of Technology's late Professor Bruno Rossi, an authority on cosmic ray physics and a pioneer in the field of x-ray astronomy. Van Speybroeck, who led the effort to design and make the x-ray mirrors for NASA's premier Chandra X-Ray Observatory, was recognized for a career of stellar achievements in designing precision x-ray optics. As Telescope Scientist for Chandra, he has worked for more than 20 years with a team that includes scientists and engineers from the Harvard-Smithsonian, NASA's Marshall Space Flight Center, TRW, Inc., Huhes-Danbury (now B.F. Goodrich Aerospace), Optical Coating Laboratories, Inc., and Eastman-Kodak on all aspects of the x-ray mirror assembly that is the heart of the observatory.

Hinners Point Above Floor of Marathon Valley on Mars Enhanced Color

This Martian scene shows contrasting textures and colors of "Hinners Point," at the northern edge of "Marathon Valley," and swirling reddish zones on the valley floor to the left. In this version of the image, the landscape is presented in enhanced color to make differences in surface materials more easily visible. The summit takes its informal name as a tribute to Noel Hinners (1935-2014). For NASA's Apollo program, Hinners played important roles in selection of landing sites on the moon and scientific training of astronauts. He then served as NASA associate administrator for space science, director of the Smithsonian National Air and Space Museum, director of NASA's Goddard Space Flight Center, NASA chief scientist and associate deputy administrator of NASA. Subsequent to responsibility for the Viking Mars missions while at NASA, he spent the latter part of his career as vice president for flight systems at Lockheed Martin, where he had responsibility for the company's roles in development and operation of NASA's Mars Global Surveyor, Mars Reconnaissance Orbiter, Mars Odyssey, Phoenix Mars Lander, Stardust and Genesis missions. Marathon Valley cuts generally east-west through the western rim of Endeavour Crater. The valley's name refers to the distance Opportunity drove from its 2004 landing site to arrival at this location in 2014. The valley was a high-priority destination for the rover mission because observations from orbit detected clay minerals there. Dark rocks on Hinners Point show a pattern dipping downward toward the interior of Endeavour, to the right from this viewing angle. The strong dip may have resulted from the violence of the impact event that excavated the crater. Brighter rocks make up the valley floor. The reddish zones there may be areas where water has altered composition. Inspections by Opportunity have found compositions there are higher in silica and lower in iron than the typical composition of rocks on Endeavour's rim. The scene spans from west-southwest at left to northwest at right. The larger of two stones close to each other in the foreground left of center is about 5 inches (12 centimeters) wide. On bright bedrock to the right of those stones, Opportunity inspected a target informally named "Pvt. George Gibson." Another inspected target, "Pvt. Silas Goodrich," is on the valley floor near the left edge of this scene. The informal names for these targets refer to members of the Lewis and Clark expedition's Corps of Discovery. The image combines exposures taken through three of the Pancam's color filters, centered on wavelengths of 753 nanometers (near-infrared), 535 nanometers (green) and 432 nanometers (violet). http://photojournal.jpl.nasa.gov/catalog/PIA19820

Hinners Point Above Floor of Marathon Valley on Mars

This Martian scene shows contrasting textures and colors of "Hinners Point," at the northern edge of "Marathon Valley," and swirling reddish zones on the valley floor to the left. The view combines six frames taken by the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity on Aug. 14, 2015, during the 4,108th Martian day, or sol, of the rover's work on Mars.
