Stunning Polar Images from NASA's Operation IceBridge

NASA isn't always just about telescopes, satellites and trips to the moon. The space agency also performs some very important research and monitoring work right here on planet Earth. One of their most vital ongoing programmes is Operation IceBridge, which looks at the troubling current rates of polar ice melting and the rise in sea levels.
Through comprehensive data collection, NASA are trying to shed some light on the matter. From 2003, they utilised their ICEsat (Ice, Cloud and land Elevation Satellite) to take the relevant measurements, but unfortunately in 2010 the satellite stopped working. Such important research couldn't stop, however, so NASA switched to the next best thing: airplanes.
