NASA astronauts Jessica Meir and ESA astronaut Sophie Adenot completed a six-and-a-half-hour spacewalk outside the International Space Station on Tuesday. [^2]

The pair began the mission to replace a particle detector on the exterior of the orbital laboratory. [^1] They also replaced a docking reference light and prepared an alpha spectrometer for upgrades. [^3]

Meir will work from the robotic arm Canadarm2, which will be operated from the interior by astronaut Anil Menon, while Adenot will be tethered to the exterior of the orbital laboratory. [^8]

With this mission, Jessica Meir becomes the third NASA astronaut with the most spacewalks, having previously made history in October 2019 by leading the first 100% female spacewalk with Christina Koch. [^5] The astronauts will also install bridge cables to reinforce data transmission systems and replace a high-definition camera on the structure. [^7]
