An 82-year-old woman climbed into a rocket in Texas on July 20, 2021, sixty years after passing the same medical screening tests used for the Mercury astronauts in a privately run program that never sent any of its women to space. She applied to NASA four times without getting in, logged 19,600 flying hours and taught more than 3,000 people to fly.

In 1961, a young pilot named Mary Wallace Funk took the same medical tests NASA had used to screen its Mercury astronauts. She was the youngest woman to take them. Everyone called her Wally. That year of testing should have been the start of something. Instead it was the start of a wait that lasted sixty years.

The program she was part of is now known as the Mercury 13. It was run privately by a doctor named William Randolph Lovelace II, who worked as a NASA contractor. He put women pilots through the same exams designed for the agency’s male candidates. Thirteen women passed those physical exams.

Some of the numbers from that testing are hard to shake. During the screening, Funk spent 10 hours and 35 minutes in a sensory deprivation tank, longer than John Glenn managed. Decades later, at the press conference after her flight, she gave her own take on how she compared with the men: “I could always beat the guys on what they were doing because I was always stronger.” That is her own account, not an official ranking. But the tank result was real, and it sat in the record for sixty years while she stayed on the ground.

What kept her there had nothing to do with flying. At the time, NASA required its astronauts to have come through military jet test piloting programs and to hold engineering degrees, paths that were closed to women. Passing the medical tests, the very tests the agency itself had ordered, led nowhere. The screening measured the body. The door was guarded by requirements the body could never satisfy.

Funk did not take the hint quietly. She went back to NASA again and again. “I got ahold of NASA four times, and said ‘I want to become an astronaut,’ but nobody would take me,” she recalled. Four applications, four rejections, each one turning on the same missing credentials rather than anything she couldn’t do in a cockpit. When Sally Ride became the first American woman in space in 1983, twenty-two years after the first American man, Funk was 44 and still flying, still not chosen.

What she did with those years is its own kind of answer. She kept flying, and she kept teaching people to fly. By the time the story caught up with her, she had logged more than 19,600 flying hours and had taught more than 3,000 people to fly.

Then, on July 20, 2021, sixty years after the tests, the wait ended in the West Texas desert. At 82, Funk strapped into Blue Origin’s New Shepard capsule near Van Horn and rode it past the edge of space. The whole flight lasted about 10 minutes and 10 seconds, reaching roughly 106 kilometres. She was the oldest person to reach space at the time, a record later broken. She was also the only member of the Mercury 13 women ever to fly.

The historian Margaret A. Weitekamp put the era’s problem plainly: the women pilots had, in her words, the “right stuff” but the “wrong sex.” That framing covers a decade of decisions, and we think it lands. The tests said one thing. The rules said another. Funk lived in the gap between them for most of her life.

What stays with us is how long that gap ran. The screening that cleared her happened in 1961. The rocket that carried her flew in 2021. Same body, same nerve, same skill, sixty years apart, and the only thing that changed was who was willing to let her on board. When someone is told to wait, it is worth asking what exactly they are being asked to wait for.

Up in the capsule, weightless, she looked out and said the plainest thing imaginable: “It’s dark up here!” At the press conference afterward, she reached for a line she had earned long before she got to use it. “I’ve been waiting a long time to finally get up there.”
