Since Icesat, the satellite NASA scientists used to collect data from the Arctic and Antarctic failed in 2009, scientists fly in a plane over the remote regions to document ice melting.
With NASA’s satellites down, scientists have to travel low and slow over Greenland’s glaciers to measure melting ice. Host Bruce Gellerman talks with science reporter Dan Grossman who hitched a ride on the science plane and also talks with NASA scientist Lora Koenig.
