NASA Operation IceBridge Hangout from Punta Arenas, Chile

NEW TIME - Because both the Ambassador and NASA's Chief Scientist were able to go on an #IceBridge  flight today! Check out the Twitter chat on @NASA_Ice and tune in on Wed for this G+ Hangout.
How NASA uses lasers to keep tabs on Antarctic glaciers and sea ice with a series of manned airplane flights over the most remote continent on Earth.
U.S. Ambassador to Chile Michael Hammer and NASA Chief Scientist Ellen Stofan join us live from the Operation IceBridge base in Puenta Arenas, Chile. Joining us from Seattle, Washington is Ben Smith. He's a senior researcher at the University of Washington in Seattle. We'll be discussing ice, our changing climate and the global mission of Earth science.
IceBridge is the link between the upcoming ICESat-2 satellite mission and our history of measuring the world’s ice coverage, flying missions in both the #Arctic and #Antarctic regions of our planet. Using LIDAR laser technology, we can see not only the height of the ice coverage, but the depths, and where liquid water lies beneath.
