In it, astronaut Karen Nyberg, one of the six people now aboard the International Space Station, demonstrates how little effort it takes to move around in microgravity.
She takes a single strand of hair from her head, stretches it across a handrail and pushes off. You can watch as Nyberg then floats across the station. (And, yes, there’s a connection to Sandra Bullock and the movie Gravity, as you’ll see.)
This isn’t her first hair-related video. In July, Nyberg demonstrated how she washes those long locks.
The 44-year-old Nyberg, who has a doctorate in mechanical engineering from the University of Texas, flew on a Space Shuttle Discovery mission to the space station in 2008. Her second trip to space began on May 28. She’s scheduled to return to Earth on Nov. 10.
