On the first of September, two women stepped beyond the threshold of the International Space Station and into the silence of orbit — not as pioneers making a point, but as engineers doing a job. NASA's Jessica Meir and ESA's Sophie Adenot spent six and a half hours replacing navigation components, laying data cables, and tending to a particle physics instrument that listens for the whispers of dark matter. It was the sixth all-female spacewalk in history, and perhaps its most telling quality was how unremarkable that fact has begun to feel.
