The
Stratospheric Observatory for Infrared Astronomy, SOFIA, was officially
welcomed on June 27,
2007 to NASA's Dryden
Flight Research Facility adjacent to Edwards Air Force Base in southern California's Mojave Desert.
SOFIA is a Boeing 747SP (special
short-bodied but long-distance model of the 747), which served as a commercial
airliner for Pan Am and then United Airlines. The aircraft now carries a
17-ton, 100-inch (2.5-meter) diameter telescope built by the German aerospace agency
DLR and its contractors. The first test flight of the combined aircraft and
telescope assembly happened on April 26 in Waco,
Texas, the location of L-3 Communications
Integrated System's plant where the aircraft modifications were accomplished.
Former shuttle astronaut, and Dryden's chief test pilot, Gordon Fullerton was
in the captain's seat on that auspicious day for NASA, DLR, and the world
community of astronomers. SOFIA's fourth
test flight was its "ferry" flight from Texas to California (see Edna DeVore's SPACE.com column from June 7).
For SOFIA's "debut" celebration, the main
doors of the central hangar at Dryden were opened, with SOFIA on the apron, its nose almost
poking inside. Three hundred seats were ready for the invited guests, mostly
current and former SOFIA program personnel, staff from
Dryden plus Edwards AFB, and some VIPs including representatives from NASA
Headquarters and Congressional aides representing their bosses who were still
in session in Washington. SOFIA was behind the podium with its white and blue NASA colors
gleaming in the bright desert morning sunshine. (Out of view a few hundred
meters away was the space shuttle orbiter Atlantis, back from space only 5 days
earlier, being processed for its eventual return to Florida.)
Before the SOFIA ceremony, some of the guests filed
past a series of exhibits along the hangar wall. I was staffing a booth
representing the Universities Space Research Association (USRA) that has
responsibility for planning and conducting SOFIA's scientific mission, and also the SETI Institute that, along with the
Astronomical Society of the Pacific, manages SOFIA's Education & Public Outreach effort. Waving an
infrared camera back and forth, I was showing people on a monitor what they look
like at wavelengths of 8 to 14 microns, in which band room- and
human-temperature objects emit most of their thermal radiation. The infrared is
a great leveler: everyone finds themselves equally unappealing at those
wavelengths, with dark noses, black glasses, dark hair with streaks of warm
scalp showing through, and glowing white lips and tongues.
One fellow
engaged me in a series of questions about the scientific goals of SOFIA and about its education program. I
explained that one of the "sweet spots" for SOFIA scientifically is to study the "life cycle" of organic molecules in
interstellar space with its set of five powerful spectrometers. SOFIA has the ability, from the
stratosphere, to collect far-infrared and sub-millimeter radiation inaccessible
even from high mountain tops. We know that an enormous amount of organic
chemistry happens in the dark clouds from which stars and planets form.
Astrobiologists are pursuing the question of how much of the organic substances
in Earth's biosphere were home-made, so to speak, or were created in space
before the Earth formed and were somehow delivered to Earth's surface later. SOFIA's capabilities will make it perfect
for providing data to scientists researching this fascinating topic, among many
others.
My intense
questioner then asked about SOFIA's
education program, and I said, "Well, my plan is to train teams of educators to
understand the research projects of astronomers and then fly onboard SOFIA with scientist partners, sort of
like junior-varsity teachers in space. I hope to compose teams comprised of
classroom teachers, science museum docents, and even avid amateur astronomers
with their own outreach programs. The goal would be that, by participating in
actual frontier research projects, these educators would go home after their
flights and, with the help of the SOFIA E&PO crew, work together to improve
science and technical education in their communities and inspire their
students. Based on the experience of the similarly-designed FOSTER program
(conducted during the last few years of SOFIA's predecessor the Kuiper Airborne
Observatory) we also expect that the educators' careers will be invigorated,
keeping them in the field and leading them on to become teachers-of-the-year or
state curriculum coordinators, as we found when we tracked down the FOSTER
alums 10 years later."
Finally,
wondering who this bright and energetic person might be, I introduced myself,
and he, seeming startled, said, "Oh, I'm Erik Lindbergh".
I stammered and said, "It's an honor". I then pulled out my business card,
which he exchanged for his. Erik Lindbergh, grandson of aviator Charles
Lindbergh, was at Dryden that morning to re-dedicate the SOFIA aircraft as the Clipper Lindbergh.
2007 is thirty years after Erik's grandmother, Anne Morrow Lindbergh,
originally dedicated the same aircraft into commercial service with that name,
which in turn was on the 50th anniversary of Charles Lindbergh's
first solo crossing of the Atlantic. Just
then the bell rang for everyone to assemble for the SOFIA ceremony.
There were
a series of speeches, mostly short and sweet, by such dignitaries as Kevin
Peterson and Pete Worden, respectively the directors of Dryden and Ames, the two NASA centers cooperating for flight tests
and then operation of SOFIA as a scientific observatory. Then
came Erik Lindbergh's turn. He spoke extemporaneously and passionately about
the crucial necessity for humanity to think outside of our various boxes. He
pointed out the value of prizes for motivating people to accomplish great
things (Erik is a trustee of the famous X Prize Foundation, and his
grandfather's trans-Atlantic flight was substantially motivated by a prize
purse). Finally, Erik praised the adventure represented by SOFIA's mission, including searching for
organic processes in space, and taking teachers onboard to motivate the
teachers and their students (my colleagues in the audience turned to me with
eyebrows raised – where did he get those details from?). It was a sincere and
inspiring speech that left those of us on the SOFIA project glowing. Finally, Erik Lindbergh went up the
jetway steps and pulled a cord to remove red-white-and-blue bunting that
covered the script "Clipper Lindbergh" behind and below the left-hand cockpit
windows, to the loud applause of all of us assembled there, cheering SOFIA at the commencement of its own
journeys to the frontiers of human knowledge and achievement.
