Randy Bresnik: Content: Image; Description: Astronaut Randy Bresnik is pictured near the base of the Orbiter Boom Sensor System on the starboard side of the cargo bay of the space shuttle Atlantis, docked with the International Space Station. Astronauts Bresnik and Mike Foreman were in the midst of the second of three scheduled spacewalks for the STS-129 mission, working in cooperation with the five current crewmembers for the orbital outpost and with their five Atlantis crewmates, all of whom provided support for the spacewalk from inside the station.

Space Shuttle Atlantis: Content: Image; Description: This view of the aft portion of the space shuttle Atlantis, including the three main engines, was provided by the Expedition 21 crew during a survey of the approaching vehicle prior to docking with the International Space Station. As part of the survey and every mission's activities, Atlantis performed a back-flip for the rendezvous pitch maneuver. The image was photographed with a digital still camera, using a 400mm lens at a distance of about 600 feet (180 meters). Image Credit: NASA

COBE Satellite Marks 20th Anniversary: Content: Image; Description: NASA's Cosmic Background Explorer (COBE) satellite rocketed into Earth orbit on Nov. 18, 1989, and quickly revolutionized our understanding of the early cosmos. Developed and built at Goddard Space Flight Center in Greenbelt, Md., COBE precisely measured and mapped the oldest light in the universe -- the cosmic microwave background. For these results, COBE scientists John Mather, at Goddard, and George Smoot, at the University of California, Berkeley, shared the 2006 Nobel Prize in physics. The mission ushered cosmologists into a new era of precision measurements, paving the way for deeper exploration of the microwave background by NASA's ongoing WMAP mission and the European Space Agency's new Planck satellite.
