NASA Dryden aircraft technician Don Bailes is assisted by two mission scientists in positioning the Laser Vegetation Imaging Sensor's instrumentation rack in NASA's DC-8 airborne science laboratory in preparation for the Fall 2009 Operation IceBridge mission. The mission is a study of Antarctica's sea ice, glaciers, and ice sheets. Developed at NASA's Goddard Space Flight Center, the laser altimeter collects data on topography and vegetation coverage.
