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.

But you can only measure where something’s going, and how fast, if you manage to hit it again and again.Blackmore's lidar reads the velocity of the objects it detects: The things moving away from the vehicle are in red, those moving toward it are in blue.
