It's "incredibly cumbersome," and "pressurized," she told Insider in an exclusive interview. She said balancing and moving around in an oversized spacesuit was particularly difficult. Wearing a spacesuit in zero gravity is hard — but it's even more difficult if it doesn't fit you.That's according to Dr Jessica Meir, who took part in a historic all-female spacewalk at the International Space Station, alongside Christina Koch, in 2019. Spacewalks, previously termed extravehicular activities, are customary operations but they pose a great risk to astronauts.
