Jessica Meir and the all-female EVA

In October 2019, NASA astronauts Jessica Meir and Christina Koch stepped outside the International Space Station and made history. They conducted the first all-female spacewalk, or EVA, an event that slingshotted Meir’s name into the mainstream. But if you’re reading this on SpacePilgrim.com, you probably know that space stuff isn’t just about feel-good headlines. You want to know what it actually means for the future of human spaceflight, for the people pulling it off, and why this specific moment mattered beyond the “first women” tag. So let’s cut the fluff. Jessica Meir isn’t just a trailblazer—she’s a working scientist, a test pilot for the next generation of exploration, and a damn good reason to keep an eye on who’s climbing into those suits.

First, the basics. Meir is a marine biologist by training, with a PhD from Scripps Institution of Oceanography. That might sound like a weird fit for an astronaut, but it’s exactly the kind of cross-disciplinary brain NASA wants. She studied how diving animals like emperor penguins and seals manage extreme pressure and low oxygen—skills that translate directly to managing the unique physical demands of spacewalks. Before her NASA selection in 2013, she did research in Antarctica, lived in underwater habitats for NASA’s NEEMO missions, and flew as a scientist on parabolic aircraft. That’s not a resume—it’s a survival manual. By the time she launched to the ISS in September 2019, Meir had already proven she could handle the grinder.

The all-female EVA itself was a logistical and engineering milestone. For months, NASA had to configure the ISS’s spacesuits to accommodate two women—not because women can’t do the work, but because the suits were originally built for a 1970s male astronaut body plan. Meir and Koch didn’t just walk; they replaced a battery charge-discharge unit on the station’s truss, a critical hardware swap that keeps the ISS powered. It was a routine job made historic by the fact that it was the first time two women worked outside a spacecraft without a guy in the loop. And here’s the kicker: it almost didn’t happen because of a suit shortage. That delay pissed off a lot of people, but it also forced NASA to rethink how it builds gear for a crew that no longer looks like a room of test pilots from 1969.

Why should you care? Because this isn’t about “representation” as a buzzword. It’s about redundancy, flexibility, and survival. If you’re launching humans to the Moon, Mars, or beyond, you can’t afford to have half your crew sidelined because the hardware was designed for one body type. Meir and Koch proved that the system can work for everyone—and that’s a hard engineering win, not a political one. When Meir performed that EVA, she spent over seven hours in a vacuum, with temperatures swinging from 250 degrees Fahrenheit in the sun to minus 250 in the shade. That’s brutal on any human, male or female. She didn’t just “inspire” anyone—she executed a flawless mission under conditions that would kill an unprotected person in seconds.

Meir’s broader contributions to the human spaceflight story are just as raw. She’s flown on Soyuz and SpaceX’s Crew Dragon, making her one of the few astronauts to command both legacy and commercial vehicles. She’s logged over 205 days in space, conducted dozens of experiments on protein crystallization, combustion, and human physiology that will help us understand how to keep crews healthy on long-duration trips. She’s been a public face for NASA during the Artemis program, pushing for women and men to work side by side on the lunar surface. But she’s also that rare astronaut who doesn’t do the media dance. She’s straight-faced, data-driven, and no-nonsense—which is exactly the kind of voice we need when talking about sending humans to live on another rock.

The all-female EVA wasn’t a stunt. It was a test run for a future where the crew of a lunar base or a Mars habitat might be all women, all men, or any mix in between. The suits, the tools, the procedures—they all passed because Jessica Meir and her team treated it like any other job. That’s the real story. Not the “first” label, but the proof that the human system works for any capable human. If you’re American, in your 20s, and watching where this space thing is headed, Meir’s walk is a reminder that the next giant leap isn’t about who walks—it’s about the fact that more of us can.

So keep an eye on Meir. She’s still active at NASA, and she’s likely to lead one of the early Artemis crews. When she does, remember she already walked the walk—literally.
