A NASA four-engine, P3-turboprop, “flying laboratory” airplane flew its last flight in a two-week-long series of flights scanning a section of Alaska's coast. The scanning was part of a collaborative project between NASA, NOAA, and representatives from the University of Colorado and the University of Alaska at Fairbanks. The project, called Arctic 2003, had collected data about sea-ice variability for comparison with data that NASA's Aqua satellite had collected. The Aqua had launched in May 2002 with a state-of-the-art radiometer for studying water systems. The P3 had carried equipment similar to Aqua's radiometer~ a Japanese-developed microwave scanner~ but because it had flown closer to the ground than the Aqua, the P3 had been able to collect sharper images. P3 flights had traveled over Norton Sound, St. Lawrence Island, St. Matthew Island, Point Hope, and Barrow. In addition to the P3 and Aqua data, ground crews had traveled to some areas to collect samples of ice and snow.
