Serena Maria Auñón-Chancellor (M.D., M.P.H.) (born April 9, 1976, in Indianapolis, Indiana) is an American physician, engineer, and NASA astronaut. She visited the ISS as a flight engineer for Expedition 56/57 on the International Space Station.
Auñón-Chancellor attended Poudre High School in Fort Collins, Colorado. She holds a B.S. degree in Electrical Engineering from George Washington University, an M.D. from the University of Texas Health Science Center at Houston (UTHealth) in 2001, and an M.P.H. degree from the University of Texas Medical Branch (UTMB) in 2006. She completed a three-year residency in internal medicine at UTMB in Galveston, Texas, in 2004, and then completed an additional year as Chief Resident. She also completed an aerospace medicine residency at UTMB. She is board certified in Internal Medicine and Aerospace Medicine.
Auñón-Chancellor was hired by NASA as a flight surgeon and spent over nine months in Russia supporting medical operations for International Space Station astronauts. She served as the deputy crew surgeon for STS-127 and Expedition 22. She also serves as the deputy lead for Orion – Medical Operations.
She received the 2009 Julian E. Ward Memorial Award from the Aerospace Medical Association for her contributions to spaceflight crewmember clinical care and development of medical kits to support launch and landing in Kazakhstan.
Auñón-Chancellor was selected as an astronaut candidate in June 2009. She completed the astronaut candidacy training program in 2011.
As part of her training, she spent two months in Antarctica from 2010 to 2011 as part of the ANSMET expedition. The ANSMET expedition consisted of a 9-member systematic team and a 4-member reconnaissance team that explored new areas where future teams may go. Collectively they returned over 1200 meteorites.
Auñón's father is Dr. Jorge Auñón, a Cuban exile who arrived in the United States in 1960; her mother is Margaret Auñón.
Auñón-Chancellor is married to physicist Dr. Jeff Chancellor, and has a step-daughter named Serafina Chancellor. They currently live in League City, Texas.
Auñón-Chancellor is a licensed amateur radio operator with the call sign of KG5TMT. She earned her Technician Class license and was granted her callsign by the Federal Communications Commission (FCC) on June 2, 2017. Auñón-Chancellor was the last astronaut to have made random (unscheduled) ham radio contacts from the ISS, generally working morning and early afternoon Saturday (US Time) passes over the US during the final weeks of her ISS mission.
