Shannon Walker was selected by NASA to be an astronaut in 2004. She holds a Bachelor of Arts degree in Physics, as well as Master of Science and a Doctorate of Philosophy degrees in Space Physics, all from Rice University in Houston. Dr. Walker’s first space flight was in 2010, a long-duration mission on the International Space Station (ISS). She served as the pilot on the Soyuz spacecraft that took her and her crew to the ISS and served as a Flight Engineer on the Station for Expeditions 24 and 25. That mission lasted 163 days, with 161 of them on the ISS. Her second mission was also a long-duration flight on the ISS. This time she was a Mission Specialist on the Crew-1 SpaceX Crew Dragon vehicle named Resilience, which launched in November of 2020. She was a Flight Engineer on the ISS during Expedition 64 and was the ISS Commander for Expedition 65 until her crew returned to Earth in May of 2021. This mission totaled 167 days.

Experience

NASA Experience

Dr. Walker began her professional career with the Rockwell Space Operations Company at the Johnson Space Center in 1987 as a Robotics Flight Controller for the Space Shuttle Program.  She worked several Space Shuttle missions as a Flight Controller in the Mission Control Center, including STS-27, STS-32, STS-51, STS-56, STS-60, STS-61, and STS‑66.  From 1990 to 1993, Dr. Walker took a leave of absence from the Johnson Space Center to attend graduate school, where she studied the solar wind interaction with the Venusian atmosphere.  In 1995, she joined NASA’s civil service and worked in the International Space Station (ISS) Program.  Dr. Walker performed robotics integration, working with the International Partners in the design and construction of the robotics hardware for the space station.  In 1998, she joined the Mission Evaluation Room (MER) as a manager responsible for coordinating the resolution of orbit technical problems for the ISS.  In 1999, Dr. Walker moved to Moscow, Russia to work with the Russian Space Agency and its contractors to do avionics integration for the Station as well as set up a program of integrated technical problem solving amongst the International Partners.  She returned to Houston in 2000 after a year in Russia and became the technical lead for the station MER as well as the Deputy Manager of the On-Orbit Engineering Office.  Prior to selection as an astronaut candidate, Dr. Walker was the Acting Manager of the On-Orbit Engineering Office.

Selected by NASA  as an astronaut in May 2004, Walker completed Astronaut Candidate Training in February 2006.  Her training included scientific and technical briefings, intensive instruction in Shuttle and International Space Station systems, physiological training, T-38 flight training, and water and wilderness survival training.  She also completed qualification in the spacewalk skills program and the Canadian Space Agency Mobile Servicing System (MSS) Robotics Operator (MRO) course.

Following her Astronaut Candidate Training, Dr. Walker assumed the duties as the crew support astronaut for the Expedition 14 crew.  As a crew support astronaut, she was the primary contact for all crew coordination, planning, and interactions, and was the primary representative for the crew while they were in space.  In addition, Dr. Walker was assigned as a Spacecraft Communicator (CAPCOM) in the Mission Control Center in Houston.  In that role, she was the primary communication link between the crew on the space station and the ground support team.  Her work as a CAPCOM culminated in her assignment as the lead Space Station CAPCOM for the STS-118 Shuttle mission which docked with the Station, carried out four spacewalks and added the S5 truss to the station.

In the summer of 2007, Dr. Walker began training for a long-duration flight on the International Space Station.  Initially assigned as a backup Expedition 19 crewmember, she also served as a backup crew member for Expedition 21/22 before being the primary crew member for Expedition 24 and 25.

After her first flight, Dr. Walker held a variety of leadership positions within the Astronaut Office.

In February 2020, she was assigned to the Crew-1 flight.

Dr. Walker is currently the supervisor for the 2021 Class of Astronauts.
