Jeanette J. Epps

Jeanette Jo Epps (born November 3, 1970) is an American aerospace engineer and retired NASA astronaut. Epps received both her M. S. and Ph.D. degrees in aerospace engineering from the University of Maryland, where she was part of the rotor-craft research group and was a NASA GSRP Fellow. She was chosen for the 20th class of NASA astronauts in 2009, graduating in 2011. She served as a member of the ISS Operations Branch and completed analog astronaut missions, including NEEMO 18 and CAVES 19. She is the second woman and first African-American woman to have participated in CAVES. She was part of the SpaceX Crew-8 mission that spent 235 days in space and 232 days on the ISS from launch on March 4, 2024 to return to Earth on October 25, 2024. one of seven children born to Henry and Luberta ( Jackson) Epps, Mississippians who moved to Syracuse as part of the Great Migration. She and her twin sister Janet excelled in math and science.

Early research and career While pursuing her M.S. in Aerospace Engineering and Ph.D in Aerospace, Aeronautical and Astronautical/Space Engineering at the University of Maryland, Epps was awarded a NASA GRSP Fellowship and went on to publish many academic works which have been highly cited. Her research was focused in the area of materials engineering, which included comprehensive testing of composite swept-tip beams, comparison of analytical models with experimental results for shape memory alloys, and use of shape memory alloy actuators for tracking helicopter rotor blades in-flight.

After graduating, Epps worked in research at Ford Motor Company, then as a Technical Intelligence Officer with the Central Intelligence Agency. She worked at the CIA for seven years, including deployments to Iraq. Before becoming an astronaut, her role at the CIA was a Technical Intelligence Officer.

NASA career In June 2009, Epps was selected as an astronaut candidate for the 20th class of NASA astronauts and later qualified in 2011. She has also completed T-38 jet training and has attended the National Outdoor Leadership School (NOLS). She has also participated in geologic studies in Hawaii. ISS Expeditions 56/57 and ESA On January 4, 2017, NASA announced that Epps would be assigned as a flight engineer to the International Space Station (ISS) in mid-2018 for Expeditions 56 and 57, but on January 16, 2018, NASA announced that Epps had been replaced by her backup Serena M. Auñón-Chancellor and would instead be "considered for assignment to future missions". The reason for Epps' removal was not stated, and a NASA spokesperson said, "These decisions are personnel matters for which NASA doesn't provide information." The Washington Post stated that "Last-minute crew changes are not unusual at NASA," although Epps’ brother blamed racism for her removal.

In 2019, Epps completed the ESA CAVES training program simulating the demands of exploring unknown terrains like those of the Moon and Mars. Epps is the second woman and first Black woman to participate in CAVES, following fellow NASA astronaut, Jessica Meir.

Epps also speaks to gatherings and has done so at the University of Maryland multiple times, including at the 2013 winter commencement ceremony for the university's engineering school. She is currently a Member of the Society for Science & the Public, in addition to the AIAA. thumb

Boeing Starliner-1 On August 25, 2020, NASA announced that Epps would join Starliner-1, the first operational mission of Boeing's Starliner to the ISS, which was delayed from its scheduled launch in the summer of 2021. According to The New York Times, the launch would have made Epps "the first Black woman to be part of an I.S.S. crew," a milestone that was ultimately reached instead by Jessica Watkins in 2022. African-American astronauts were members of Space Shuttle crews to the ISS while the station was being constructed, but until Victor Glover went to the station in Nov 2020, none had made an extended stay as a crew member.

Epps began cross-training on the SpaceX Crew Dragon spacecraft as the Starliner-1 mission kept getting delayed.

SpaceX Crew-8 In August 2023, NASA announced that Epps would fly as a mission specialist on SpaceX Crew-8, a half-year mission to the ISS that launched on March 4, 2024 onboard the Crew Dragon Endeavour. The mission made her the second African-American woman to be part of a long-duration mission onboard the ISS. The mission spent extra time in space because of a month-long delay in launching SpaceX Crew-9. They then spent a few extra weeks removing seating and other equipment in Endeavour that was needed for Boeing Crew Flight Test mission astronauts Sunita Williams and Butch Wilmore. Weather in the landing zones then caused further delays, but Epps and her crewmates finally splashed down off of the coast of Pensacola, Florida on October 25, 2024. The mission’s 235 days in low-Earth orbit set the single-mission record for the longest time an American crewed spacecraft spent in space.
