Satellite Contributions to Climate Change Studies

Abstract

This year, well-deserved attention has been given to longtime NASA employee Katherine Johnson (Figure 1) for her crucial calculations for the flights of the Mercury and Apollo astronauts in the 1960s-attention that has come through the best-selling book Hidden Figures by Margot Lee Shetterly and the Oscar-nominated movie based on the book. Johnson is still alive, now 98 years old, and has relayed how thrilled she was with her NASA job and the privilege it afforded her of being part of the grand enterprise of sending human explorers into space. I too, for the past 38 years, have been thrilled to be a part of NASA and to have the privilege to be a participant in one of NASA's other grand enterprises, this one being to use satellites to observe Earth from space, monitor and analyze its changes, and benefit humanity through the knowledge obtained.
