Early life and education

Jennifer Anne MacKinnon Sidey was born on 3 August 1988 in Calgary.^[2][3] She earned a Bachelor of Engineering with honours in mechanical engineering from McGill University, where she conducted research in collaboration with the Canadian Space Agency (CSA) and the Flight Research Laboratory of the National Research Council Canada on flame propagation in microgravity.^[3]

In 2015, she completed a PhD in engineering at Jesus College, Cambridge. Her doctoral research, supervised by Professor Nondas Mastorakos, focused on combustion processes.^[2]

Academic career

Before joining the CSA, Gibbons was a lecturer in internal combustion engines at the Department of Engineering at the University of Cambridge. Her research centered on turbulent flame dynamics and pollutant reduction in combustion systems.^[4] She also taught undergraduate and graduate students in the Energy, Fluid Mechanics, and Turbomachinery Division on topics such as energy production, thermodynamics, and flame physics.^{[citation needed]}

In 2016, Gibbons received the Institution of Engineering and Technology's Young Woman Engineer of the Year Award and a Royal Academy of Engineering Young Engineer of the Year Award.^{[citation needed]}

CSA career

Gibbons was selected by the CSA in 2017 as part of its fourth astronaut recruitment campaign, joining Joshua Kutryk in the 2017 CSA Group.^[5][6] She was the third female astronaut candidate chosen by the CSA, following Roberta Bondar and Julie Payette. At 28 years old, she became the youngest astronaut candidate ever selected by the agency.^[7]

In July 2017, Gibbons relocated to Houston, to complete the two-year NASA Astronaut Candidate Training Program at the Johnson Space Center, training alongside the 2017 NASA astronaut class.

On 22 November 2023, during a public ceremony at CSA headquarters, Gibbons was announced as the backup for Jeremy Hansen on the Artemis II mission. The mission, part of NASA's Artemis program, is slated to fly no earlier than April 2026.^[8][9][10]
