ICESat-2 Laser Fires for 1st Time, Measures Antarctic Height

10.03.2018
With each of its 10,000 pulses per second, the laser instrument aboard NASA's ICESat-2 is sending 300 trillion green photons of light to the ground and detecting the few that return: the method it uses to measure Earth’s changing ice. By the morning of Oct. 3, ICESat-2 returned its first height measurements across the Antarctic ice sheet.
