NASA’s Flights Over Antarctic Continent Bridge Satellite Gap

NASA is currently conducting Operation Ice Bridge, a six-year campaign of annual flights to each of Earth’s polar regions designed to help scientists bridge the gap between NASA’s Ice, Cloud and Land Elevation Satellite (ICESat) — which is operating the last of its three lasers — and ICESat-II, scheduled to launch in 2014 by providing the needed data collected by researchers on board the DC-8, a 157-foot-long airborne laboratory and the largest aircraft in NASA’s airborne science fleet that accommodates many instruments.
