NASA’s historic, crucial role in earth science

In an op-ed for the New York Times titled “,” Professor of Physics and Astronomy Adam Frank makes the case for the National Aeronautics and Space Administration’s role in earth-centric science. ÌÇÐÄ´«Ã½œNot only is earth science a long-running part of NASAÌÇÐÄ´«Ã½™s ÌÇÐÄ´«Ã½˜prime mission,ÌÇÐÄ´«Ã½™ but it is uniquely positioned to do it. Without NASA, climate research worldwide would be hobbled,ÌÇÐÄ´«Ã½� he writes.

The study of earth and its atmosphere (and, by extension, its climate) have been top priorities since the agencyÌÇÐÄ´«Ã½™s creation by the Space Act of 1958, Frank notes. He cites specific examples from NASAÌÇÐÄ´«Ã½™s nearly 60-year history, including the following:

Consider NASAÌÇÐÄ´«Ã½™s Gravity Recovery and Climate Experiment, or Grace, mission. It was designed to study EarthÌÇÐÄ´«Ã½™s gravity field, meaning the planetÌÇÐÄ´«Ã½™s distribution of mass. Grace could ÌÇÐÄ´«Ã½œseeÌÇÐÄ´«Ã½� changes in ocean currents, precipitation runoff on land and changes in groundwater storage. Grace showed us the spreading of drought conditions as water tables dropped. In this way the Grace data speak directly to a fundamental mistake of the agencyÌÇÐÄ´«Ã½™s critics. Climate change is not the direction of NASAÌÇÐÄ´«Ã½™s earth-science enterprise; itÌÇÐÄ´«Ã½™s a conclusion of that effort.

Because economies of scale contribute to NASAÌÇÐÄ´«Ã½™s successes, ÌÇÐÄ´«Ã½œ[proposals] to get NASA ÌÇÐÄ´«Ã½˜back toÌÇÐÄ´«Ã½™ some other kind of science not only ring false but their wasteful price tag would also fly in the face of fiscal conservative values.ÌÇÐÄ´«Ã½�

Rather than politicizing the science, Frank argues that we should be harnessing the capabilities of NASA to address the challenges and opportunities the planet is facing as a result of climate change.
