Defying Gravity, Part 11
The gURLs who Spacewalk
Spacewalking astronauts are big right now thanks to a certain blockbuster movie full of A-List Hollywood Stars. In preparing for her role in Gravity, actress Sandra Bullock turned to real-life astronaut Cady Coleman for advice about what life in space is really like. But the big screen is obviously nothing like the real thing.
Stepping outside of a spacecraft that is orbiting our planet at speeds of thousands (and thousands) of miles per hour is a frightening prospect. So who are the brave women that have actually performed this heroic work in real life?
To this day, eleven women have made the journey. The final entry in our list is astronaut Tracy Caldwell Dyson.

Tracy Dyson flew as a Mission Specialist on Space Shuttle Endeavour (STS-118) and was a member of the crew on the ISS. While on Expedition 24, she spent 22 hours outside of the station on three separate EVAs. Among her tasks was the replacement of a malfunctioning coolant pump on the station. Interestingly, she was also the first astronaut to be born after Apollo.
“One of the greatest lessons I’ve learned on my journey of becoming and serving as an astronaut for NASA is to not give away my self-confidence. I believe it’s a lesson I’m still learning.” – Tracey Caldwell Dyson, from Women@NASA.
