- NASA astronauts Anil Menon and Jessica Meir ventured outside the International Space Station on Thursday for a spacewalk that lasted 6.5 hours
- The spacewalk crew installed mounting hardware designed to prepare the station's 3B power channel for the future installation of new roll-out solar arrays
Why it matters: This outing was strictly preparatory — the mounting hardware laid during the 6.5-hour excursion readies the ISS's 3B power channel for new roll-out solar arrays to be installed in a later mission, making each spacewalk a building block in a multi-mission power-grid upgrade.
