NASA

Grier Wilt is an ExtraVehicular Activities (EVA) Flight Controller and Instructor at the NASA Johnson Space Center in Houston, Texas. In this capacity, Ms. Wilt plans spacewalk missions aboard the International Space Station, trains an international cadre of astronauts for those missions, and supports those EVAs real-time from Mission Control. Concurrent with her International Space Station work, Ms. Wilt serves on the Artemis team to enable exploration spacewalk missions on the lunar surface, NASA’s next step beyond low earth orbit. 

Prior to her current role, Grier served as the Deputy Director of NASA Operations in Star City, Russia overseeing US astronaut training at the Gagarin Cosmonaut Training Center while also serving as the Business Manager for the NASA Human Spaceflight Program in Russia. 

Grier holds a Master’s degree in Mechanical Engineering from the University of Washington in Seattle and Bachelor’s Degrees in Mechanical Engineering and International Studies from The Pennsylvania State University. Her graduate research focused on bone loss mitigation in reduced gravity which resulted in the opportunity to fly aboard multiple zero gravity parabolic flight campaigns for her research. Throughout her career and education, she has lived abroad in Germany, Australia, Morocco, and Russia.

Outside of work, Grier actively volunteers in the community and enjoys participating in STEM outreach in order to increase access to the sciences for underserved communities. Her hobbies include hiking, rock climbing, sailing, and flying as a private pilot.
