The high-stakes engineering of maintaining life in orbit
In short: Watch how astronauts navigate the vacuum of space to perform critical repairs on the International Space Station. This footage captures the precise, multi-hour maneuvers required to keep our orbital laboratory functional and safe.
Astronauts conduct complex extravehicular activities (EVAs) to maintain essential station infrastructure. For example, Doug Wheelock and Tracy Caldwell Dyson performed a series of spacewalks in August 2013 to replace a failed ammonia pump module responsible for cooling the International Space Station.
Other missions involve high-precision hardware swaps, such as replacing retroreflectors on the Harmony module to aid spacecraft navigation during docking. These excursions also include installing data-relay jumper cables and preparing radiators for future maintenance, representing the 284th spacewalk dedicated to station assembly and upgrades.
