SUNNYVALE, Calif., Aug. 26, 2013 /PRNewswire/ -- Ten years ago, NASA's Spitzer Space Telescope – built, integrated and tested at Lockheed Martin [NYSE: LMT] Space Systems in Sunnyvale – roared into space from the Kennedy Space Center in Florida, carrying the observatory into an Earth-trailing orbit around the sun. The Spitzer Space Telescope is a space-borne, cryogenically-cooled infrared observatory that studies objects ranging from our Solar System to the distant reaches of the Universe. Lockheed Martin Space Systems in Denver provides mission support for Spitzer spaceflight operations in conjunction with the Jet Propulsion Laboratory and the California Institute of Technology. "We are extremely proud of our decades of work on behalf of NASA, and honored to have played such a key role in the Spitzer Space Telescope program," said Jim Crocker, Lockheed Martin vice president of Civil Space. "It is particularly satisfying because celebrating Spitzer's 10 th anniversary seemed unlikely at the outset as the mission was designed to last between two and five years." In May 2009 the onboard liquid helium supply on Spitzer was exhausted. The mission was extended, however, because the two shortest wavelength detectors in Spitzer's camera continued functioning perfectly as the observatory trailed far behind the Earth in its orbit, through the cold of deep space. The Spitzer Space Telescope views the universe in infrared light, which is largely blocked by the Earth's atmosphere. With Spitzer, astronomers have determined that Earth-like planets form around many, if not most of the nearby Sun-like stars in our galaxy, suggesting that the potential for life might be more common than previously thought. In looking at our own galaxy – the Milky Way galaxy – the observatory has given astronomers valuable insights by revealing where new stars are forming. In addition, the infrared eyes of Spitzer are ideal for studying distant planet forming disks, and characterizing planets beyond our Solar System.
