NASA's highly modified Douglas DC-8 jetliner which operates as a flying science laboratory is brought into a hangar at the Armstrong Flight Research Center in Palmdale, California on July 7, 2016. The Atmospheric Tomography mission, NASA's research studies of the Earth's atmosphere, will take place this July and August as the DC-8 begins a 26-day journey from the North Pole, over the Pacific Ocean to New Zealand then across to the tip of South America, turning north over the Atlantic Ocean to the Arctic. / AFP PHOTO / Frederic J.
