Former astronaut and recent administrator of the National Oceanic and Atmospheric Administration, Dr. Kathryn Sullivan said, "It's a pretty remarkable little blue marble that we live on." Sullivan was discussing the environmental changes you can see from space during our Earth Day episode of "What's New in Aerospace." Sullivan shared her perspective on our changing planet, the importance of satellite technologies in looking at Earth, and how all that data can be combined and shared on a global scale.
