Tracy Caldwell Dyson (born Tracy Ellen Caldwell; August 14, 1969) is an American chemist and NASA astronaut. She was a mission specialist on Space Shuttle Endeavour flight STS-118 in August 2007 and has participated in two long-duration missions to the International Space Station, Expedition 23 and 24 from April to September 2010 and Expedition 70 and 71 from March to September 2024. She has completed four spacewalks, logging nearly 24 hours of extravehicular activity.

Early life and education

Caldwell Dyson was born in Arcadia, California. She is the younger of two girls. In the early 1980s, she and her family moved to Beaumont, California, where her father worked as an electrician and where she attended junior high school and high school. Her recreational interests include running, weight training, hiking, softball, basketball, and auto repair and maintenance.

She attended California State University, Fullerton, where she competed on the CSUF Titans' track and field team as a sprinter and long jumper.

As an undergraduate researcher at California State University, Fullerton, she designed, constructed and implemented electronics and hardware associated with a laser-ionization, time-of-flight mass spectrometer for studying atmospherically relevant gas-phase chemistry. She also worked as a lab assistant in the university's research and instructional safety office, where she performed environmental monitoring of laboratories using hazardous chemicals and radioactive materials and calibrated survey instruments and helped process chemical and radioactive waste.

Career

NASA

In June 1998, Caldwell Dyson was selected by NASA, and began NASA training two months later, in August 1998. Her astronaut candidate training included orientation briefings and tours, numerous scientific and technical briefings, intensive instruction in Shuttle and International Space Station (ISS) systems, physiological training, ground school to prepare for T-38 flight training, as well as learning water and wilderness survival techniques. Completion of this training and evaluation qualified her for flight assignment as a mission specialist.

In 1999, Caldwell Dyson was assigned to the Astronaut Office ISS Operations Branch as a Russian Crusader, participating in the testing and integration of Russian hardware and software products developed for ISS. In 2000, she was assigned prime crew support astronaut for the ISS Expedition 5 crew, serving as their representative on technical and operational issues throughout the training and on-orbit phase of their mission.
