New Satellite's Lasers Will Track Tiny Changes in Polar Ice

New Satellite's Lasers Will Track Tiny Changes in Polar Ice

Once it settles into orbit 310 miles above the Earth, the satellite will start collecting data using a specially designed laser device that will give scientists more data about exactly where ice is melting and how fast.The NASA satellite will scan the Earth’s surface using six green laser beams to measure glaciers and floating sea ice.
