Michael King—EOS Senior Project Scientist

On March 18, Mr. William Townsend, acting Associate Administrator for the Office of Mission to Planet Earth, announced the selection of winning proposals for endto- end science missions known as Earth System Science Pathfinders (ESSP). Under the terms of the competition, these ESSP proposals included not only instruments and data analysis, but also spacecraft, launch vehicle, and satellite command and control systems, and were cost capped at $60 M for the first mission and $90 M for the second mission. These principal investigator-led missions are to be developed from approval to launch in just 3 years (for the first mission) with little direct NASA oversight, and are expected to yield exciting new science that complements, but does not duplicate, NASA Earth Observing System (EOS).

The Vegetation Canopy Lidar (VCL) mission, led by Prof. Ralph Dubayah of the University of Maryland, College Park, will provide the first global inventory of the vertical structure of forest canopies across the Earth using a multibeam laser-ranging lidar system.
