Friendly Solano Skies – and Crowds

Against a backdrop of blustery winds from the San Francisco Bay area and beautiful, cloudless skies, an estimated daily crowd of 100,000 gathered at Travis Air Force Base, Calif., to see the U.S. Air Force Thunderbirds put on their trademark spectacular air shows at the “Skies Over Solano” Air Power Expo July 30-31.

Fellow NASA research pilot Hernan Posada and I were invited to represent NASA at the event, near Fairfield, Calif. We flew one of Dryden’s Beechcraft B-200 Super King Airs on a route that led us from our home base at Edwards over the snow-covered Sierra Nevada range and into California’s agriculture-rich Sacramento/San Joaquin valleys. Upon arrival Friday afternoon, the ramp was filling with a wide assortment of civilian and military aircraft, classic and current, as we met other pilots and aircrews from around the country.

Our hosts, the 60th Air Mobility Wing, commanded by Col. James Vechery, held an evening BBQ mixer for performers and exhibiters at the wing’s air museum. Along with the terrific welcome – and appropriate safety advisories – Col. Vechery advised us that the proper response to hearing someone mention “Team Travis” was a loud, unanimous cry of “air power!!!” The 60th AMW operates three different types of aircraft: cargo-carrying C-5s and C-17s as well as KC-10 aerial refueling tankers.

The next two days were filled with awesome exhibitions of aerial skills, ranging from gut-wrenching civilian aerobatics to ear-splitting military aircraft fly-bys. Even the U.S. Air Force Academy Parachute Team managed to maneuver to pinpoint landings in the gusty winds.

Personally, our greatest thrills came from the visiting public, who eagerly greeted us with enthusiasm and excitement over the fact that NASA was there. Initial questions from the public centered mainly on the future of human space exploration. We reminded most that humans are living in space as we speak, and will continue to do so as we expect further developments in space exploration in the coming years. We also mentioned the proliferation of robotic planetary exploration that is continuing. Of course, our primary messages were about that first “A” in NASA, and how we’re heavily engaged in using aircraft for two primary NASA missions: research in aeronautics and in Earth science. In particular, our B200 display board showed how these aircraft are used for vital research, from testing a cave-detection sensor destined for a Mars orbiter to wildfire location missions.

The most rewarding part of all of this was that 100% of the public’s response is that they are diehard NASA fans and want to see more and greater accomplishments in the future. Oh yeah – and handing out those NASA stickers and pins is always a crowd pleaser, too!

Seeing Stars

NASA Dryden Student Intern
We were screeching down the runway, engines blasting, accelerating until the shuddering giant leapt off the ground into flight. SOFIA was in the air. The thought of flying on board an airplane that has a hole in its side and carries a 17-ton telescope was a little disconcerting, but after several weeks on the SOFIA project as an intern, learning all about the effort it took to make the aircraft operational, I trusted that we would return to Palmdale safely.

Within the first few minutes of the flight, fellow intern Stephanie Sodergren and I were giggling with excitement from our seats in what used to be the modified 747’s first-class cabin. We quickly hung a picture of the predicted flight pattern, planning to highlight the path as we traveled overnight. We got out our NASA “meatball” tattoos and stuck them to our biceps. “It’s only been thirty minutes and we’ve done so much! We still have nine and a half more hours of flight to go!”
 
It was a clear and calm night over the Pacific Ocean. I gazed through the cockpit windows on the upper deck at the billions of stars visible, and thought solemnly that this may be the closest I will ever be to the stars. I pretended I was in space, gazing down at clouds I imagined to be the continents of Earth. Below, on the lower deck, the scientists and flight crew were looking through the telescope at pinpoints in this vast, unknown universe.
 
Sitting at the conference table on the passenger deck, I gave myself a fast lesson in the basics of star formation, using a textbook written by Dana Backman, SOFIA education and public outreach director. Relating the information to my college course material and my knowledge of the GREAT – German Receiver for Astronomy at Terahertz Frequencies – instrument mounted on the SOFIA telescope, I gained a deeper understanding of how complex technologies are used to “look” through the cocoons of dust to see stars forming. Two astrophysicists sat across from me, receiving the GREAT’s real-time data output. “Here, come look at this!” they would say to me over the audio distribution system’s headsets. They turned their laptop screen around so I could see the fresh data on newborn “cocooned” stars in the giant gas nebula known as the Elephant Trunk formation. When it was announced that we were flying at 45,000 feet, the highest altitude flown on a SOFIA science mission, the scientists and I exchanged excited glances.

Several hours later, we were nearing the end of the journey home. I was the last of the five interns awake, eating cookies with the astrophysicists as they showed me their compiled data. It was a successful science mission, and everyone was in a good mood. A faint glow began coming from the horizon, so I headed back up to the cockpit for the landing. As the light from stars shining across the heavens was overcome by our own star’s light, I felt a twinge of sadness about my SOFIA flight coming to an end. I was exhausted, but part of me wanted to go right back up to the stratosphere. As I was listening in on the headset in the cockpit, I could hear an Australian airline on approach to California. Land was now in sight as mountains began to emerge beneath snowy clouds. I estimated we were flying right over California State University, Long Beach – my college!

With the desert approaching in the distance, I felt such a sense of pride for what had been accomplished overnight. All the effort by engineers, technicians, scientists and managers, German and American, had congealed to produce scientific data from a world incomprehensibly far from our own island of life. I had never felt our species’ innate aspiration to explore and discover more strongly than at that moment. Humbled by the vastness of space, I was beaming with pride and confidence in mankind.
 
I can only describe my experience of flying on SOFIA as beautiful. From the bright stars to the flight crew’s camaraderie to the notion of such a small speck of humanity – me – gazing out into the limitless unknown, I had learned so much besides the basics of star formation that night. I was ecstatic, thinking about the universe we live in. With so much effort being put into each mission by everyone in the SOFIA program, I had to pause and reflect on the words of J.F. Kennedy as he initiated our quest to the moon: NASA does what it does not because it is easy, but because it is hard.
 
My 10-week internship experience has been fantastic. I have met so many great, smart people who have helped me learn all about NASA, SOFIA, science, program management, astronomy, and much more. I had the best summer working with my mentor, Stephen Jensen, and fellow interns at NASA. I’m looking forward to applying what I learned and sharing my experiences back at school, hopefully inspiring others to pursue similar experiences. Because of this internship, I was able to secure a job working with SOFIA’s education and public outreach department, and will be working with Stephanie Sodergren on the department’s website during the next school year.
 
Thank you, NASA, for giving me this opportunity, and for showing the world what humans are capable of achieving.
