via Tumblr http://bit.ly/1N7Cqxk Academy Award winning actor and environmental activist @LeonardoDiCaprio visited Goddard Saturday to talk about NASA Earth science with former astronaut Piers Sellers, the current deputy director of Goddard’s Sciences and Exploration Directorate.

They discussed NASA missions studying changes in the Earth’s atmosphere, water and land masses for a climate change documentary DiCaprio has in production.

Using Goddard’s Hyperwall high-definition display system, they viewed presentations based on actual science data captured by NASA’s fleet of satellites orbiting Earth, as well as climate and ocean-current modeling done by the NASA Center for Climate Simulation at Goddard.

Mr. DiCaprio also viewed the clean room where the next-generation James Webb Space Telescope is being developed.
