Contrails, the lines of clouds from high-flying aircraft that crisscross the skies, are familiar sights, but they may have an unseen effect on the planet – trapping heat in the atmosphere. Working with Boeing, and other partners, NASA researchers are collecting data to see how new, greener aviation fuels can help reduce the problem.
