Details of the astronauts’ journey during their walk outside the space station

Two astronauts walked outside the International Space Station to boost power to the station, but time ran out before they could place the first in a series of new solar arrays designed to boost the station’s electrification. And the French astronaut from the European Space Agency (ESA), their spacewalk, which lasted for seven hours and 15 minutes, installed the first set of only six solar arrays more capable and efficient than the old ones.

According to the “space” website, astronauts attached the first solar arrays to the International Space Station (iROSA) in front of a 20-year-old array located on the far left side of the space station’s core.

“As the years go by, things get more efficient and smaller, and this is no exception,” Kimbrough said in an interview with NASA reviewing his spacewalk with Bisquet. “These arrays are much smaller than the original arrays that we’re going to put next to them.”

The eight old solar array pavilions were originally built with a design life of 15 years, and are showing signs of deteriorating energy production.

Also, when the new arrays are used in conjunction with areas still exposed on the larger and older arrays, the upgraded system will be able to increase the space station’s electricity supply by 20% to 30%.

Work on the array had to be paused, though, to allow time for Kimbro to return to the airlock to reset his spacesuit’s data display and remove a slight pressure rise in his suit’s cooling unit.

The two astronauts were also scheduled for another spacewalk on Sunday (June 20) to deploy the second iROSA system to augment the P6/4B solar array, and NASA flight controllers will now re-plan the activities and timing of that extravehicular activity as needed to complete Install the first set before starting the next.
