Unmanned NASA Aircraft Crashes During Science Mission
NASA is investigating the loss of a small unpiloted aircraft over the Arctic Ocean Friday, July 26, while it conducted research on sea ice. The Sensor Integrated Environmental Remote Research Aircraft (SIERRA) was about four hours into a planned six-hour flight when it experienced a problem that caused it to lose altitude and crash in the ocean. The incident occurred at 6:15 p.m. AKDT (10:15 p.m. EDT).
The flight originated from Oliktok Point, off the northern coast of Alaska. The crash site is extremely remote, about 40 miles farther north in the Beaufort Sea. No one on the ground was injured. Environmental impacts at the crash site are expected to be minimal because of the aircraft’s small size. At the time, SIERRA had less than six gallons of fuel and oil aboard. A mishap investigation is underway.
The aircraft was one of three unmanned aerial vehicles taking part in a science experiment called the Marginal Ice Zone Observations and Processes Experiment (MIZOPEX). Mission objectives were to probe the ocean's role in recent declines in Arctic sea ice using a sophisticated set of radars and other instruments.
SIERRA was a medium-class, unmanned aircraft system with a wingspan of 20 feet and a weight of 400 pounds. It was designed to perform remote sensing and atmospheric sampling missions in isolated and often inaccessible regions, such as over mountain ranges, the open ocean, or the Arctic and Antarctic regions. NASA acquired SIERRA from the U.S. Naval Research Laboratory in 2006 and conducted its first mission surveying sea ice off the coast of Svalbard, Norway, in 2009. The vehicle was valued at $250,000.
