[:en]Spacewalking Astronauts Prep Station for New Photo voltaic Wings[:]
CAPE CANAVERAL, Fla. (AP) — Spacewalking astronauts ventured out Sunday to put in help frames for brand spanking new, high-efficiency photo voltaic panels arriving on the Worldwide Area Station later this 12 months.
NASA’s Kate Rubins and Victor Glover emerged from the orbiting lab lugging 8-foot (2.5-meter) duffle-style luggage full of tons of of kilos of mounting brackets and struts. The tools was so large and awkward that it needed to be taken aside like furnishings, simply to get by way of the hatch.
“We all know it’s tremendous tight in there,” Mission Management radioed.
The astronauts headed with their unusually massive load to the far port aspect of the station, cautious to not stumble upon something. That’s the place the station’s oldest and most degraded photo voltaic wings are positioned.
With extra individuals and experiments flying on the house station, extra energy shall be wanted to maintain every part operating, in response to NASA. The six new photo voltaic panels — to be delivered in pairs by SpaceX over the approaching 12 months or so — ought to increase the station’s electrical functionality by as a lot as 30%.
Rubins and Glover needed to assemble and bolt down the struts for the primary two photo voltaic panels, as a consequence of launch in June.
The eight photo voltaic panels up there now are 12 to twenty years previous — most of them handed their design lifetime and deteriorating. Every panel is 112 toes (34 meters) lengthy by 39 toes (12 meters) large. Tip to tip counting the middle framework, every pair stretches 240 toes (73 meters), longer than a Boeing 777′s wingspan.
Boeing is supplying the brand new roll-up panels, about half the dimensions of the previous ones however simply as highly effective due to the newest photo voltaic cell know-how. They’ll be positioned at an angle above the previous ones, which is able to proceed to function.
A prototype was examined on the house station in 2017.
Sunday’s spacewalk was the third for infectious illness specialist Rubins and Navy pilot Glover — each of whom may find yourself flying to the moon.
They’re amongst 18 astronauts newly assigned to NASA’s Artemis moon-landing program. The following moonwalkers will come from this group.
Final week, Vice President Kamala Harris put in a congratulatory name to Glover, the primary African American astronaut to dwell full time on the house station. NASA launched the video alternate Saturday.
“The history-making that you’re doing, we’re so happy with you,” Harris mentioned. Like different firsts, Glover replied, it received’t be the final. “We wish to ensure that we will proceed to do new issues,” he mentioned.

Rubins will float again out Friday with Japanese astronaut Soichi Noguchi to wrap up the photo voltaic panel prep work and to vent and relocate ammonia coolant hoses.
Glover and Noguchi had been amongst 4 astronauts arriving through SpaceX in November. Rubins launched from Kazakhstan in October alongside two Russians. They’re all scheduled to return to Earth this spring.
