The spacewalk started at 08:40 Eastern Time (12:40 GMT) and is expected to last approximately six and a half hours. [^3]

The astronauts exited the Quest airlock to replace a retroreflector located on the front port of the Harmony module. [^4]

The United States space agency NASA marked 2026 as one of the most important years since the Apollo era, advancing projects for a return to the Moon and Mars. [^5]

This mission represents the 284th extravehicular activity dedicated to the assembly, maintenance, and improvement of the International Space Station. [^6]

Meir and Adenot will prepare the Alpha Magnetic Spectrometer, a cosmic particle detector that has been searching for dark matter and antimatter since 2011, for future upgrades. [^7]
