Forest-mapping instrument for space station passes major milestone

A laser-based instrument for mapping the 3-D structure of Earth's forests has passed a major milestone toward deployment on the International Space Station (ISS). The Global Ecosystem Dynamics Investigation (GEDI), led by the University of Maryland, College Park, and built by NASA's Goddard Space Flight Center in Greenbelt, Maryland, successfully transitioned to "Phase B," moving from requirements development and mission definition to preliminary design. GEDI will provide the first comprehensive, high-resolution measurements of the vertical canopy structure of Earth's temperate and tropical forests.
