1 00:00:01,000 --> 00:00:05,240 NEW INSTRUMENT WILL MAP CARBON WORLDWIDE IN 3-D 2 00:00:07,260 --> 00:00:11,780 In order to manage forests and mitigate climate change 3 00:00:12,270 --> 00:00:20,690 scientists need to understand where our carbon is being taken up and where it is already stored. 4 00:00:21,070 --> 00:00:27,340 So we are building a laser to measure trees from space. 5 00:00:29,360 --> 00:00:35,970 The Global Ecosystem Dynamics Investigation (GEDI) instrument will spend two years on the ISS 6 00:00:36,310 --> 00:00:44,830 using eight laser beams to measure every leaf, branch, tree trunk, and shrub in the ground path down on the surface. 7 00:00:45,390 --> 00:00:49,090 Photons in the laser pulse ricochet back to GEDI 8 00:00:49,110 --> 00:00:54,370 providing an intricate 3-D map of forest canopies 9 00:00:55,110 --> 00:01:03,230 Built by NASA and the University of Maryland, GEDI’s laser can peer inside even the densest tropical forests
