When Jessica Meir floated outside the International Space Station in October 2019, she wasn’t just conducting maintenance—she was helping make history.
From Scientist to Spacewalker
Before becoming an astronaut, Meir was a marine biologist and physiologist, studying how animals survive in extreme environments. That same curiosity would later take her beyond Earth aboard Soyuz MS-15.
The First All-Female Spacewalk
Alongside Christina Koch, Meir participated in the first all-female spacewalk, repairing a critical power unit on the ISS. This milestone wasn’t just symbolic—it demonstrated capability, readiness, and the normalization of women in high-stakes space operations.
Science in Microgravity
During her mission, Meir contributed to research including:
Human physiology in space
Combustion experiments
Biological studies in microgravity
Her work supports the long-term sustainability of human spaceflight.
Perspective That Transcends Borders
Meir often described Earth as “a shared home without boundaries,” reinforcing the importance of global collaboration—both in space and on the ground.
Looking Ahead
Meir is also part of NASA’s Artemis Program, positioning her among the astronauts who could help shape humanity’s return to the Moon.
