During his visit, Mr. DiCaprio interviewed Dr. Piers Sellers, an Earth scientist, former astronaut and current deputy director of Goddard’s Sciences and Exploration Directorate. The two discussed the different missions NASA has underway to study changes in the Earth’s atmosphere, water and land masses for a climate change documentary that Mr. DiCaprio has in production.
