Editor's Corner

Michael King, EOS Senior Project Scientist

I’m pleased to announce the selection of two new space mission proposals as part of the Earth System Science Pathfinder (ESSP) program that will give new insight into the Earth’s carbon cycle and how oceans affect and respond to climate change. NASA has selected the Orbiting Carbon Observatory (OCO) and the Aquarius mission from 18 ESSP proposals received. Of the original 18 proposals, six were selected for a detailed assessment, with the OCO and Aquarius missions now moving on toward final implementation.

The Orbiting Carbon Observatory will provide global measurements of atmospheric carbon dioxide needed to describe the geographic distribution and variability of carbon dioxide sources and sinks. Aquarius will provide the first-ever global maps of salt concentration on the ocean surface, a key area of scientific uncertainty in the oceans’ capacity to store and transport heat, which in turn affects Earth’s climate and the water cycle. Dr. David Crisp of NASA’s Jet Propulsion Laboratory will be the principal investigator for the OCO mission and Dr. Chet Koblinsky of NASA’s Goddard Space Flight Center will serve as principal investigator for the Aquarius mission. Both of these missions will...
