Female Astronauts Said To Face Discrimination Over NASA's Space Radiation Concerns, Huffington Post
"Depending on when you fly a space mission, a female will fly only 45 to 50 percent of the missions that a male can fly," Peggy Whitson, the former chief of NASA's Astronaut Corps, said. "That's a pretty confining limit in terms of opportunity. I know that they are scaling the risk to be the same, but the opportunities end up causing gender discrimination based on just the total number of options available for females to fly. [That's] my perspective."
