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 her area of study was the solar wind interaction with the Venusian atmosphere. In 1995 she joined the NASA civil service and began working in the International Space Station (ISS) Program at the Johnson Space Center. Dr. Walker worked in the area of robotics integration, working with the ISS International Partners in the design and construction of the robotics hardware for the Space Station. In 1998 she joined the ISS Mission Evaluation Room ( MER) as a manager for coordinating on-orbit problem resolution for the International Space Station. In 1999 Dr. Walker moved to Moscow, Russia to work with the Russian Space Agency and its contractors in the areas of avionics integration for the ISS as well as integrated problem solving for the ISS. She returned to Houston in 2000 after a year in Russia and became the technical lead for the ISS MER as well as the Deputy Manager of the On-Orbit Engineering Office. Most recently, prior to selection as an astronaut candidate, Dr. Walker was the Acting Manager of the On-Orbit Engineering Office.

Selected by NASA in May 2004. In February 2006 she completed Astronaut Candidate Training that 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. Completion of this initial training qualified her for various technical assignments within the Astronaut Office and future flight assignment as a mission specialist. Dr. Walker is in dedicated training for long duration flight on the International Space Station and is currently assigned as a back-up Expedition 19 crew member.
