Editor's Corner

Michael King—EOS Senior Project Scientist

On December 22, Dr. Ghassem Asrar, Associate Administrator of the Office of Earth Science, announced the selection of winning proposals for end-toend small spacecraft missions known as Earth System Science Pathfinders (ESSPs). Under the terms of the competition, these ESSP mission proposals included not only instruments and data analysis, but also spacecraft, launch vehicle, and sa tellite command and control systems, and were cost capped at $90 M for the first mission and $120 M for the second mission. These principal investigator-led missions are to be developed from approval to launch in just three years (for the firs t mission) with little direct NASA oversight, and are expected to yield exciting new science that complements, but does not duplicate, the science from NASA's Earth Observing System (EOS). Furthermore, NASA policy precludes development of any mission that competes with or duplicates other capabilities available from foreign or commercial partners.

The Pathfinder Instruments for Cloud and Aerosol Spaceborne Observations- Climatologie Etendue des Nuages et des Aerosols (PICASSO-CENA), led by Dr. David Winker of NASA Langley Research Center, Hampton, VA, was selected as the primary second mission for full-scale development. It is designed to address the role of clouds and aerosol particles and their impact on the Earth's radiation budget-a balance of solar energy reaching the Earth, and lost to space, that ultimately controls the temperature of the Earth.
