Piers Sellers, a climate scientist and former astronaut who gained fame late in life for his eloquent commentary about the earth's fragility and his own cancer diagnosis, has died. He was 61.
NASA spokesman Patrick Lynch tells The Associated Press that Sellers died on Friday morning. Lynch did not provide a cause of death, but Sellers had been suffering from Stage 4 pancreatic cancer.
The British-born Sellers was deputy director for sciences and exploration at NASA's Goddard Space Flight Center in Greenbelt, Maryland. He started working for NASA as a scientist in 1982 and joined its astronaut corps in 1996. He made three flights to the International Space Station, the last in 2010.
Sellers shared his astronaut's perspective on climate change in Leonardo DiCaprio's documentary, Before the Flood.
