GEDI Overview

B-roll for the live shot will be added on Thursday April 18 by 6:00 p.m. EST. B-roll for Earth Day live shot. Canned interview with NASA Scientist Dr. Lesley Ott looking off camera. TRT 3:35 Canned interview with NASA scientist Dr. Melinda Webster. TRT 3:50 Celebrate Earth Day With NASAUse the hashtag #PictureEarth and share the beauty of EarthWhen you think of NASA you might be picturing astronauts, images of Jupiter and far-away galaxies, basically everything beyond our planet. But did you know that one of NASA’s biggest fields of study is our home, Earth?Of all the planets that NASA studies, none have matched the complexity of Earth. For 50 years, NASA has been sharing images of Earth that have changed our views of the planet. From the deep blue oceans to the many colors of the aurora and Earth’s vast landscapes.This Earth Day, NASA invites you to celebrate the planet we call home with a world-wide #PictureEarth social media event. Take a photo of the nature around you and share it on your social media accounts using the hashtag #PictureEarth.Join NASA scientists on 6:00 a.m. to 12:00 p.m. EDT on Friday, April 19 to find out how your viewers can join the fun and learn more about our interesting/unique/strange home.NASA has a fleet of satellites that are regularly collecting data to help us better understand and admire this little blue strange and mysterious planet.

The Global Ecosystem Dynamics Investigation (GEDI) instrument will measure forest structure and canopy height, from a perch on the International Space Station. By sending laser pulses down to Earth, GEDI will generate a three-dimensional map of forest structure that will allow scientists to better understand where carbon is being stored around the world.Music: "Hard Thinking" by Leonard-Morgen and "Hidden Files" by Sam Dodson [PRS] Complete transcript available.Watch this video on the NASA Goddard YouTube channel. NASA's new laser instrument, the Global Ecosystem Dynamics Investigation, or GEDI, has advanced laser technology that will reveal the makeup of remote forest ecosystems around the globe. GEDI will soar above Earth at 17,150 miles per hour onboard the International Space Station. Its measurements of the height of leaves, branches, trees, and shrubs below its path will help scientists map the structure of forests and better understand how ecosystems are storing or releasing carbon. GEDI's lidar instrument sends laser pulses down to Earth, where they penetrate the globe’s temperate and tropical forests. The laser beams ricochet off the first thing they hit, which can be a leaf atop a dense canopy, a protruding branch, or the ground from which the forest emerges. The energy returned to the GEDI telescope on the International Space Station will provide an intricate three-dimensional map of forest canopies and carbon storage.Led by the University of Maryland in collaboration with NASA's Goddard Space Flight Center, GEDI has the highest resolution and densest sampling of any lidar every put in orbit.

Music: Navigating the Nebulae by Or Kribos and Udi HarpazComplete transcript available. The Global Ecosystem Dynamics Investigation – or GEDI, pronounced like "Jedi," of Star Wars fame – instrument is undergoing final integration and testing this spring and summer at NASA's Goddard Space Flight Center, Greenbelt, Maryland. The instrument is expected to launch aboard SpaceX's 16th commercial resupply services mission, targeted for late 2018. GEDI is being led by the University of Maryland, College Park; the instrument is being built at NASA Goddard.From its perch on the exterior of the orbiting laboratory, GEDI will be the first space-borne laser instrument to measure the structure of Earth's tropical and temperate forests in high resolution and three dimensions. These measurements will help fill in critical gaps in scientists' understanding of how much carbon is stored in the world's forests, the potential for ecosystems to absorb rising concentrations of carbon dioxide in Earth's atmosphere, and the impact of forest changes on biodiversity.
