12 p.m. EDT — Talk and Visuals: “The Next Generation Blue Marble from Suomi NPP
Often cited as the most-viewed photograph of all time, the view of Earth’s disk from Apollo 17 is emblematic of our home planet as an isolated blue marble. Despite the ubiquity of the Blue Marble, few people realize NASA has viewed the Earth since the agency’s creation. In this talk Rob Simmon of NASA’s Earth Observatory will discuss the history of NASA’s evolving views of Earth, from the first weather satellites to the latest climate missions, from the orbit of Mercury to the edge of the Solar System. He will also describe the techniques used to build images that simulate the view from space, including cloud-free global composites and a picture of the Eastern Hemisphere from NASA and NOAA’s newest Earth-observing mission, Suomi NPP. Speaker: Robert Simmon, NASA’s Earth Observatory
Length: 20 minutes
