In space, zero gravity causes hair to increase in volume, get curly and float. A woman astronaut with long hair is encouraged to pull back their hair into a ponytail. Astronaut and Navy commander Suni Williams had a plan before she left Earth on the current space shuttle mission, to cut her hair and send the ponytail back to Earth on the Space Shuttle Discovery to be made into a wig for a cancer patient undergoing chemotherapy.

To state this woman is awe-inspiring is an understatement. In the ABC News Ponytail in Space report, when asked if she is a role model for young girls, Williams is quoted as saying, "I hope so. I wasn't always the sharpest tool in the shed, the smartest kid on the block, but I think there was a lot of persistence. And I hope kids understand it is OK to fail, if you learn something from failing. Maybe you don't get the first thing that you want, but if you are good at what you do, and you try hard, some things sort of fall into place. If you want something, you can obtain it."

I would say the courageous, determined and spirited Williams is a heroic role model for everyone, regardless of gender or age. According to the report, the smart, tall, willowy brunette with a wicked sense of humor, and zest for life was dancing to Bruce Springsteen's Born to Run before she climbed into her spacesuit for a grueling 7½-hour spacewalk on Saturday.
