NASA has honored Piers Sellers, an astronaut on the Space Shuttle Atlantis in 2002, who recently died of pancreatic cancer, the administration said.
NASA administrator Charles Bolden said Sellers joined the NASA astronaut corps in 1996 and flew to the International Space Station in 2002, 2006 and 2010, performing six spacewalks and various space station assembly tasks.
He later served as deputy director of the sciences and exploration directorate and acting director of the Earth sciences division at NASA´s Goddard Space Flight Center in Greenbelt, Maryland.
NASA remembers Sellers as a public servant dedicated to NASA, the nation and the world. He was a strident defender and eloquent spokesperson for Earth.
