Dr. Julie Robinson, Deputy Director for Earth Science, NASA 

When humans explore space, we have to reproduce all the same systems that Earth provides to sustain life—water, air, surface, and biota — in order to survive in the unforgiving environment of space. In several decades of continuous presence on the International Space Station, we have learned surprising things about the engineering of systems that support human life.  At the same time, we have collected extraordinary data about the Earth system passing below us. Spaceflight gives us the opportunity to understand climate change and mitigate its effects to improve the resilience of communities on our home planet. Join Julie Robinson, NASA’s deputy director for earth science, as we explore what living in space teaches us about life on Earth.
