SOFIA
Astronomy Jet Makes First Flight
International astronomers are a major step closer to unlocking secrets
of the cosmos. A modified 747 airliner mounting a huge infrared
telescope took to the skies for the first time on April 26,
2007 as a NASA flight crew put the big jet through the first
of several shakedown flights since the airplane underwent major
modifications at L-3 Communications in Waco, Texas. NASA research
pilot and astronaut Gordon Fullerton led the crew making the
historic first flight.
To enable the 45,000-pound infrared telescope to scan the skies, the
747 was modified by cutting a 16-foot tall opening in the aft fuselage,
and fairing 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 huge 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.
After a few shakedown flights over Texas, SOFIA will fly to NASA's
Dryden Flight Research Center in California’s Mojave Desert
for flight tests combined with integration of its sophisticated
astronomy hardware.
SOFIA project manager Bob Meyer said the integrated approach will enable
scientists to begin making infrared images even before the modified
jetliner has completed its flight testing program.
Pilot Gordon Fullerton's NASA crew for the first flight of SOFIA included
copilot Bill Brockett, flight engineer Larry LaRose, and flight test
engineer Marty Trout. L-3's flight test analyst Don Stonebrook was also
a crewmember.
SOFIA is a joint international effort by NASA and DLR, the German
Aerospace Center. In addition to Dryden, NASA's Ames Research
Center at Moffett
Field in California's San Francisco Bay area is deeply involved in
the science of SOFIA. The entire effort is supported by Universities
Space
Research Association (USRA), a non-profit group of universities created
in 1969 by the National Academy of Sciences.
