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 part of the Expedition 23 and Expedition 24 crew on the International Space Station from April 2010 to September 2010. She has completed three spacewalks, logging more than 22 hours of extravehicular activity.[1][2] She is currently in space since March 23, 2024 for a third time, for a six-month mission onboard the ISS.

Early life and education

Caldwell Dyson was born in Arcadia, California.[1] 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. Her recreational interests included running, weight training, hiking, softball, basketball, and auto repair and maintenance.

She attended

U.S. Naval aviator George Dyson.[2] She believes in God,[4] and was raised as a Methodist. [citation needed
].

As an undergraduate researcher at California State University, Fullerton, she designed, constructed and implemented electronics and hardware associated with a laser-ionization,

gas-phase chemistry.[5][6] 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. During college and after it, she also worked as an electrician and inside wireman for her father's electrical contracting company, where she performed commercial and light industrial construction.[1]

At the

scanning tunneling microscopy system.[1]

In 1997, Caldwell Dyson received the Camille and Henry Dreyfus Postdoctoral Fellowship in Environmental Science to study atmospheric chemistry at the University of California, Irvine.[8] There, she investigated reactivity and kinetics of atmospherically relevant systems using atmospheric pressure ionization mass spectrometry, Fourier transform infrared and ultraviolet absorption spectroscopies. In addition, she developed methods of chemical ionization for spectral interpretation of trace compounds. Caldwell Dyson has published and presented her work in numerous papers at technical conferences and in scientific journals.[1]

Career

NASA

In June 1998, Caldwell Dyson was hired by

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. During ISS Expeditions 4 through 6, Caldwell Dyson served as an ISS spacecraft communicator (CAPCOM) inside Mission Control. In 2003, she made a transition to the Astronaut Shuttle Operations Branch and was assigned to flight software verification in the Shuttle Avionics Integration Laboratory and worked supporting launch and landing operations at Kennedy Space Center, Florida. Caldwell Dyson also served as Lead CAPCOM for Expedition 11.

Between her second and third flights, Caldwell Dyson continued to work inside Houston’s Mission Control Center as CAPCOM for both space shuttle and space station operations, serving as the lead CAPCOM for various ISS missions, including the lead and development of the CAPCOM cadre for

Kjell Lindgren
.

Caldwell Dyson initiated and led several projects to improve training and operations aboard the ISS, most notably developing the EVA Qualification training flow (EVQ) for astronaut candidates.

As Tracy Dyson, she is the host of a series on NASA TV called StationLife, which focuses on facets of life aboard the International Space Station.[9]

On March 21, 2017, Dyson stood behind

President Trump as he signed a bill for NASA to send humans to Mars in the 2030s and receive $19.5 billion in 2018 funding. Dyson and fellow NASA astronaut Chris Cassidy presented Trump with an official flight jacket during the ceremony.[10]

STS-118

Caldwell Dyson was assigned to

Columbia disaster
.

On August 8, 2007, Caldwell Dyson lifted off for the first time on the 119th Space Shuttle flight, the 22nd flight to the station, and the 20th flight for Endeavour. During the mission, she successfully added another truss segment, a new gyroscope and external spare parts platform to the International Space Station. A new system that enables docked shuttles to draw electrical power from the station to extend visits to the outpost was activated successfully. A total of four spacewalks (EVAs) were performed by three crew members. Endeavour carried some 5,000 pounds of equipment and supplies to the station and returned to Earth with some 4,000 pounds of hardware and no-longer-needed equipment. Traveling 5.3 million miles in space, the STS-118 mission was completed in 12 days, 17 hours, 55 minutes and 34 seconds. On day 7 of the flight of STS-118, Caldwell-Dyson celebrated her 38th birthday in space.

Expedition 23/24

Caldwell Dyson was assigned for her second space flight on November 21, 2008. Her second space mission consisted of a six-month mission to the International Space Station.[12]

After a successful liftoff on April 2, 2010, from the

Mikhail Korniyenko and following a two-day rendezvous and docking maneuver with the ISS, she joined Expedition 23 as a flight engineer and transferred on June 2, 2010, to Expedition 24 again as a flight engineer after the departure of the Soyuz TMA-17
.

During the first half of her flight, Caldwell-Dyson and the Expedition 23 crew were joined by the STS-131 crew from April 7 to April 17. This period was the first and only time that four women were together on board the same spacecraft: Caldwell-Dyson, NASA astronauts Stephanie Wilson and Dorothy Metcalf-Lindenburger, and JAXA astronaut Naoko Yamazaki. From May 16 to May 23, the second and last Space Shuttle visiting mission for Caldwell-Dyson's flight, STS-132, joined the Expedition 23 crew for the installation of the Russian-built module Rassvet.

The second half of Caldwell-Dyson's mission was marked by the failure of a coolant pump at the beginning of August. Caldwell Dyson performed her first spacewalk on August 7, 2010, with NASA astronaut

EVAs was to prepare the malfunctioning coolant pump for replacement on the next spacewalks; this took place on August 11, 2010, and August 16, 2010. She performed all of this contingency EVA.[13]

After 176 days, 1 hour, 18 minutes and 38 seconds in space, Caldwell-Dyson landed in Kazakhstan on September 25, 2010.[14] During this spaceflight, she completed three spacewalks, logging 22 hrs and 49 minutes of EVA work to replace a malfunctioning coolant pump.[13]

Since December 2021, Tracy Caldwell-Dyson has been back in flight training as a backup crew member of the Soyuz MS-24. She backed up her NASA astronaut colleague Loral O'Hara.[15]

On May 29, 2023, she was officially assigned to the

Marina Vasilevskaya. She is planned to return after six months on 24 September 2024 with Oleg Kononenko and Nikolai Chub.[16]
