![]() Get the latest updates on NASA missions, watch NASA TV live, and learn about our quest to reveal the unknown and benefit all humankind. The mission is managed by NASA with operational support from NOAA and its Joint Polar Satellite System, which manages the satellite's ground system. brings you the latest images, videos and news from America's space agency. Suomi NPP sends its data once per orbit to a ground station in Svalbard, Norway, and continuously to local direct broadcast users distributed around the world. But closer observations revealed that astronomers had captured the largest cosmic explosion ever witnessed, an event thought to have been. The spacecraft flies 824 kilometres (512 miles) above the surface in a polar orbit, circling the planet about 14 times a day. It started as an unremarkable flicker in the night sky. Named for satellite meteorology pioneer Verner Suomi, NPP flies over any given point on the earth’s surface twice each day at roughly 1:30 am and 1:30 pm. In this case, auroras, fires, and other stray light have been removed to emphasize the city lights. VIIRS detects light in a range of wavelengths from green to near-infrared and uses filtering techniques to observe dim signals such as gas flares, auroras, wildfires, city lights, and reflected moonlight. The night time view of the earth was made possible by the "day-night band" of the Visible Infrared Imaging Radiometer Suite. It took 312 orbits and 2.5 terabytes of data to get a clear shot of every parcel of the earth’s land surface and islands.
