A new NASA laser instrument set to launch to the International Space Station in December will help scientists create the first three-dimensional map of the world’s temperate and tropical forests. The Global Ecosystem Dynamics Investigation, or GEDI, is scheduled to launch on SpaceX’s Falcon 9 rocket. From the station, GEDI’s advanced laser technology will reveal the three-dimensional structure of forest ecosystems around the globe.GEDI pronounced “Jedi,” will soar over both the dark side and the light side of Earth at 17,150 miles per hour. Measurements of the height of foliage, branches, trees and shrubs below its path will yield new insights into how forests are storing or releasing carbon.
