Jessica Ulrika Meir is an American NASA astronaut, marine biologist, and physiologist. Her passion for exploration and science was evident from an early age. Meir’s interest in space and nature was sparked by watching the Space Shuttle missions on television. She pursued postdoctoral research in comparative physiology at the University of British Columbia, delving into the intriguing world of diving physiology and behavior of emperor penguins in Antarctica. This research allowed her to unveil the secrets of these incredible creatures and shed light on their adaptations to extreme aquatic environments. Meir’s talent and expertise were further recognized when she participated in ESA CAVES, a training course where international astronauts undertake missions in a space-analogue cave environment. On September 25, 2019, Meir’s dream culminated in her launch to the International Space Station (ISS) aboard Soyuz MS-15. She served as a Flight Engineer during Expeditions 61 and 62, conducting critical experiments, carrying out maintenance tasks, and contributing to the overall success of the missions. One of the most significant milestones in Meir’s career occurred on October 18, 2019, when she and Christina Koch made history as the first women to participate in an all-female spacewalk. Meir’s remarkable contributions have earned her numerous accolades and recognition, including being named one of Time magazine’s 100 Most Influential People of 2020.
