Astronaut Piers Sellers dies of pancreatic cancer
Former NASA astronaut Piers Sellers, a veteran of three Space Shuttle missions, died on Friday, Dec. 23, 2016, in Houston after more than a year of battling pancreatic cancer. He was 61.
Sellers was diagnosed in October 2015. He only revealed he was battling Stage 4 pancreatic cancer in January of this year (2016) in a New York Times column where he wrote he hoped to see solutions to climate change in his lifetime and would continue to work on climate research until he died.
Overseeing scientists researching climate and weather, Sellers was serving as the deputy director of sciences and exploration at Goddard Space Flight Center. It was a position he held since 2011.
NASA Administrator Charles Bolden, the current head of the U.S. Space Agency, said in a statement that Sellers was dedicated to all forms of exploration.
“His curiosity and drive to uncover new knowledge was generously shared with audiences around the world, both from space and in wide travels to reach as many people as possible with an essential understanding of our fragile planet,” Bolden said.
Born on April 11, 1955, in Crowborough, Sussex, in the United Kingdom, Sellers graduated with honors with a bachelor’s degree in ecological science from the University of Edinburgh in Scotland in 1976. He received a doctorate in biometeorology (the study of the relationship between organisms and weather) from Leeds University in 1981.
Sellers also had an accomplished career as a climate scientist. Before joining NASA’s astronaut corps he mapped a model of Earth’s climate system and focused on satellite remote-sensing studies. His research was focused on studying how the Earth’s biosphere and atmosphere interact. He combined the field work of various aircraft, satellites, and ground systems in Kansas, Russia, Africa, Canada, and Brazil.
However, it is his career as an astronaut that Sellers will, perhaps, be best remembered for. He participated on three Space Shuttle missions where he logged some 41 hours conducting Extravehicular Activities (EVAs) during six spacewalks.
Selected as an astronaut candidate in April 1996, Sellers worked part time in Moscow as a technical liaison on International Space Station computer software.
His first flight to space was aboard Space Shuttle Atlantis’ STS-112 mission in 2002. That flight’s primary objective was to install the S1 Truss segment in joint operations with the space station’s Expedition 5 crew.
During that flight, Sellers performed three spacewalks and logged a total of 19 hours and 41 minutes of EVA.
His second flight, STS-121, occurred in 2006. This was a 13-day flight aboard Space Shuttle Discovery, during which time he tested new equipment and procedures to increase the safety of Space Shuttle missions.
Sellers, along with fellow astronaut Mike Fossum, performed three EVAs to test the 50-foot (15-meter) long Orbiter Boom Sensor System, an extension to the Shuttle’s arm that would allow for post-launch inspections of the orbiter’s critical heat-resistant re-entry tiles.
His final flight occurred once again on Atlantis on STS-132 in 2010. Sellers served as the robotics officer and mission specialist-1 during that flight. Three spacewalks were performed to install a spare antenna and a stowage platform, replace batteries on the P6 Truss that stores solar energy. They also retrieved a power data fixture for installation on a later flight.
Over the course of three shuttle missions, Sellers was in space for a total of 34 days, 23 hours, and 3 minutes.
“Today we lost a tremendous public servant who was dedicated to NASA, the nation and the world,” Bolden said at the end of his statement. “He was a strident defender and eloquent spokesperson for our home planet, Earth. Spacewalker and scientist, free thinker and friend to our planet, and all who seek new knowledge, to say he will be missed would be a gross understatement.”
Those that knew and worked with Sellers, including members of the elite corps of astronauts that he flew and trained with, expressed their feelings on his passing.
“Saddened by the loss today of Piers Sellers – a wonderful friend and a champion for our planet,” former NASA astronaut Nicole Stott told SpaceFlight Insider. “His dedication, optimism, spirit, and humor were inspirational and will be missed. We should all take his lead and do all we can to improve life here on Earth and all the precious life that it supports.”
Heather Smith's fascination for space exploration – started at the tender age of twelve while she was on a sixth-grade field trip in Kenner, Louisiana, walking through a mock-up of the International Space Station and seeing the “space potty” (her terminology has progressed considerably since that time) – she realized at this point that her future lay in the stars. Smith has come to realize that very few people have noticed how much spaceflight technology has improved their lives. She has since dedicated herself to correcting this problem. Inspired by such classic literature as Anne Frank’s Diary, she has honed her writing skills and has signed on as The Spaceflight Group’s coordinator for the organization’s social media efforts.
