NASA Completes First Checkout Flight Of Airborne Observatory

SPACE SCOPES

Flying at altitudes above 40,000 feet, this special 747SP will rise above most atmospheric water vapor to give the 98.4-inch diameter infrared telescope clear access to collect infrared images from space.

NASA successfully completed the first of several planned checkout test flights of the Stratospheric Observatory for Infrared Astronomy (SOFIA) aircraft. The flight took place in Waco, Texas, to observe the low-speed and low-altitude handling performance of the aircraft. NASA research pilot and former astronaut Gordon Fullerton led the crew making the historic first flight.

"Today's first flight of SOFIA is a major milestone for the program and I want to thank the entire SOFIA team for all of its hard work over the years in making this first flight a success," said Jon Morse, director of the Astrophysics Division, NASA Headquarters, Washington.

The tests are required prior to the aircraft's ferry flight to its home base at NASA's Dryden Research Center, Edwards, Calif., tentatively scheduled for late May or early June. Once the aircraft arrives at Dryden, further development and a series of flight tests will take place leading up to science observations scheduled for 2009 or 2010.

Prior to this first successful flight, the airplane underwent major modifications at L-3 Communications Integrated Systems in Waco, Texas. To enable the 45,000-pound infrared telescope to scan the skies, the 747SP was modified by cutting a 16-foot tall opening in the aft fuselage, and equipping it with a sliding door.

By flying at altitudes above 40,000 feet, this special 747SP will rise above most atmospheric water vapor to give the 98.4-inch diameter infrared telescope clear access to collect infrared images from space.

The telescope can be positioned anywhere in the skies, unlike ground-based telescopes, and between science missions it can be serviced and reconfigured as needed to accomplish world-class astronomy.

SOFIA will study the universe in the infrared spectrum. SOFIA also will be used to develop observational techniques, new instrumentation, and to educate young scientists and teachers in the discipline of infrared astronomy.

Hubble Celebrates Its Seventeenth Birthday With The Birth Of A Star

Baltimore MD (SPX) Apr 24, 2007
In celebration of the 17th anniversary of the launch and deployment of NASA's Hubble Space Telescope, a team of astronomers is releasing one of the largest panoramic images ever taken with Hubble's cameras. It is a 50-light-year-wide view of the central region of the Carina Nebula where a maelstrom of star birth - and death - is taking place.
