It is no easy task to capture the shadow of Pluto as it travels across the surface of Earth at more than 53,000 mph-but that is exactly what NASA scientists and flight crew did on the night of June 29, 2015. In this 4-minute, 55-second video, the Stratospheric Observatory for Infrared Astronomy (SOFIA) aircraft's infrared telescope successfully observed the dwarf planet as it passed in front of a distant star. This event, known as an occultation, allowed scientific analysis of Pluto and its atmosphere by flying SOFIA at the right moment to an exact location where Pluto's shadow fell on Earth. This 4-minute, 55-second video shows the careful planning and real-time adaption of the observatory’s flight path leading up to observation, and highlights the data’s contributions to the New Horizons mission.
SOFIA is a joint project of NASA and the German Aerospace Center (DLR). The aircraft is operated by NASA's Armstrong Flight Research Center and based at Hangar 703 in Palmdale, CA. NASA’s Ames Research Center in Moffett Field, CA is home to the SOFIA Science Center that is managed by NASA in cooperation with the Universities Space Research Association headquartered in Columbia, MD, and the German SOFIA Institute at the University of Stuttgart.
