A recent DID article explained the differences between the smaller MQ-1 Predator and MC-1 Sky Warrior UAVs, and their more advanced cousin the MQ-9 Reaper hunter-killer that can fly at 50,000 feet. As we noted at the time, however, the MQ-9 is also the basis for other UAVs, some of which are used for research. One is NASA’s Ikhana unmanned research aircraft (pron. ee-kah-nah, Choctaw language, means “intelligent”). NASA has also been intelligent, running wildfire related exercises and missions since August. Ikhana flew over several of the Southern California wildfires Wednesday, Oct 24/07, using its payload capacity to carry special thermal-infrared imaging equipment that can look right through smoke and haze to record high-quality imagery of key hot spots.

Each flight is being coordinated with the US FAA to allow the remotely piloted aircraft to fly within the national airspace while maintaining separation from other aircraft. The imagery is processed on board, downlinked, and overlaid on Google Earth maps at NASA Ames Research Center in Northern California, Then it’s made available by the National Interagency Fire Center to incident commanders in the field to aid them in allocating their fire-fighting resources. The mission was controlled by pilots remotely from a ground control station at NASA’s Dryden Flight Research Center at Edwards Air Force Base. The above 3-D image was taken at 10:21 a.m. PDT over the Harris Fire in San Diego County, looking west. The hot spots (in yellow) are concentrated on the ridgeline in the left center of the photo.

Nice work. The UAV continued its flights Thursday, and more MQ-9 Ikhana images can be found via this NASA page. You can also look at Ikhana’s page of past photos, which includes one detailing its wildfire sensor package.
