Astronaut Joshua Kutryk of the Canadian Space Agency (CSA), participating in Expedition 75 as a flight engineer, conducted a spacewalk at the International Space Station. During the operation, his spacesuit was fully sealed, and the protective helmet visor was lowered to protect against the effects of open space. The purpose of the spacewalk was to install a new roll-out solar array on the port side of the station's truss structure. Such solar panels represent modern technology that allows for a significant increase in electrical power generation for the ISS without substantially increasing the mass and volume of the structure during transportation. Spacewalks remain among the most complex and demanding operations in the work of ISS crews, requiring careful preparation and coordinated interaction between the astronauts themselves and ground flight control services. Updating the station's power system is important for maintaining its long-term operational capability and providing power for scientific experiments conducted onboard.
