NASA scientists gather data from Mars, two asteroids and a distant galaxy as they fly on SOFIA, NASA's Stratospheric Observatory for Infrared Astronomy 747 plane, as they fly on a 10-hour, 5,000-mile flight from California to Texas, then up to British Columbia and back on Tuesday, Jan. 24, 2017. Four educators, two from California and two from Wisconsin, flew on the flight at part of NASA's Airborne Astronomy Ambassadors program. (Photo by Rachel Luna/The Sun, SCNG)
