What's that in the sky? It's our researchers taking to the skies to capture data about the effects of jet biofuels on aircraft emissions and contrails. In this image, our DC-8 research aircraft, which had the job of burning the biofuel, leads one of the "sampling" chase aircraft across an early morning sky near NASA's Armstrong Aircraft Operations Facility in Palmdale, Calif. The science instruments on the chase aircraft, as they were flown through the DC-8's wake, were able to record more data about how the emissions mixed with air.

The tests confirm that the biofuels result in at least 50 percent reduction in soot emissions when burning the blended fuel as opposed to standard jet fuel. The goal of the research is to help lead to more environmentally friendly aircraft designs.
