Piers Sellers is currently Deputy Director of the Sciences and Exploration Directorate and Acting Director of the Earth Sciences Division at NASA/GSFC. He was born and educated in the United Kingdom and moved to the U.S. in 1982 to carry out climate research at NASA/GSFC. From 1982 to 1996, he worked on global climate problems, particularly those involving interactions between the biosphere and the atmosphere, and was involved in constructing computer models of the global climate system, satellite data interpretation and conducting large-scale field experiments in the USA, Canada, Africa, and Brazil. He served as project scientist for the first large Earth Observing System platform, Terra, launched in 1998. He joined the NASA astronaut corps in 1996 and flew to the International Space Station (ISS) in 2002, 2006, and 2010, carrying out six spacewalks and working on ISS assembly tasks. He returned to Goddard Space Flight Center in June, 2011.

Leonardo DiCaprio visited Goddard Saturday to discuss Earth science with Piers Sellers

Academy Award®- winning actor and environmental activist Leonardo DiCaprio visited NASA’s Goddard Space Flight Center in Greenbelt, Maryland on Saturday, April 23, 2016. 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. Using a wall-size, high-definition display system that shows visual representations based on actual science data, Mr. DiCaprio and Dr. Sellers discussed data results from NASA’s fleet of satellites in Earth’s orbit. During his visit, Mr. DiCaprio also visited the facility holding NASA’s James Webb Space Telescope that is being developed as a large infrared telescope with a 6.5-meter primary mirror. The telescope will be launched on an Ariane 5 rocket from French Guiana in October of 2018, and will be a premier observatory of the next decade, serving thousands of astronomers worldwide.

Orion Crew Module Arrival at Mole Pier

The Orion crew module is being moved into a covered structure at the Mole Pier at Naval Base San Diego in California where it will be prepared for return to NASA's Kennedy Space Center in Florida. Orion was secured on its crew module recovery cradle in the well deck of the USS Anchorage after it was recovered from the Pacific Ocean. After lifting off at 7:05 a.m. EST on Dec. 5, atop a Delta IV Heavy rocket from Space Launch Complex 37 at Cape Canaveral Air Force Station in Florida, Orion completed a two-orbit, four-and-a-half hour mission to test systems critical to crew safety, including the launch abort system, the heat shield and the parachute system. NASA, the U.S. Navy and Lockheed Martin coordinated efforts to recover Orion after splashdown in the Pacific Ocean. The Ground Systems Development and Operations Program led the recovery efforts.
