Spacewalkers Finish Installing Next-Gen Solar Arrays on the ISS, Boosting Station Power
A five-year modernization reached its final installation.
Mark
So what actually happened here? It sounds like a finishing line.
Mimi
It is. Astronauts installed the last add-on solar array on the ISS, which completes a power upgrade that took about five years.
Mark
And this was the 101st spacewalk?
Mimi
Yes, NASA's 101st at the station. The upgrade was reported as aiming to boost station power by about 30 percent.
Luke
I want to flag that word, aiming. The 30 percent is the goal. The reporting I can see doesn't say the station is producing 30 percent more.
Mimi
That's fair. The measurement comes after the arrays are fully activated.
Mark
Why does more power matter up there?
Mimi
The source material doesn't spell out specifics. NASA's weekly update does show a station busy with biomedical science and maintenance, all of which runs on that supply.
Luke
Careful, though. That's a reasonable connection, but the excerpts don't say the extra power is earmarked for any particular research.
Mark
What don't we know?
Luke
Who did the spacewalk, how long it lasted, and exactly what hardware went in. Those aren't in what we have.
Mimi
What we do have is the quote, "We got it done," which tells you how the crew felt about closing out five years of work.
Le Pouls
- The final solar array went onto the ISS during a spacewalk, ending a five-year power upgrade.
- The 101st spacewalk in station history carried the weight of a long, multi-outing campaign.
- The upgrade targets roughly a 30 percent boost in station power, a goal not yet confirmed by measurement.
- Crews and mission control now shift from installation to activation, and the real output of the new arrays is still unknown.
Far above the atmosphere, in the quiet arc of the International Space Station, astronauts stepped outside to attach the last of a new generation of solar arrays, closing a five-year effort to renew the station's electrical heart. It was the 101st spacewalk in the station's history, and it arrived as one milestone among many ordinary tasks that keep a fragile outpost running. The stated purpose is to lift the station's available power by roughly thirty percent, though that figure remains a target rather than a measured result. Whether the promise will be kept can only be learned once the new wings are awake and the station's energy is counted.
The headline from the International Space Station was short and plain: "We got it done!" Spacewalking astronauts had finished installing the last of the next-generation solar arrays, bringing a long modernization of the station's electrical supply to its close.
The work marked NASA's 101st spacewalk at the station. Reporting from CBS News described the final add-on array completing the power upgrade, and Spaceflight Now framed it as the end of a five-year effort. A campaign like this is built from many separate outings, and this one was the last.
The stated goal, as USA Today reported, was to raise available power by about 30 percent. That is an aim, not a result, and nothing in the current reporting shows what the station produces now.
NASA's weekly roundup placed the milestone among routine work: cleanup, biomedical science and maintenance. It is a fair picture of life aboard the station, where major construction and daily housekeeping happen side by side.
The next chapter is performance. Once the arrays are fully activated and output is measured, it will be clear whether the promised gain has arrived.
The headline that came out of the International Space Station this week was short and plain: "We got it done!" Spacewalking astronauts had finished installing the last of the next-generation solar arrays, closing out a long-running project to modernize the station's electrical supply.
The work was NASA's 101st spacewalk at the ISS. Coverage from CBS News described the astronauts installing the final add-on solar array, which completed the power upgrade. Spaceflight Now framed it as the end of a five-year effort to upgrade the station's power supply. A multi-year campaign like this is built from many separate outings, and this one was the last.
The goal, as USA Today reported it, was to raise the station's available power by about 30 percent. That figure is the stated aim of the upgrade, not a measured result. Nothing in the available reporting says what the station is actually producing now that the final array is in place.
NASA's own weekly roundup folded the milestone into the station's regular routine. Its summary for the week listed spacewalk cleanup, biomedical science and maintenance as the work wrapping up around the installation. That is a fair picture of life aboard the ISS: a major construction milestone sits alongside ordinary housekeeping and ongoing research.
The available material is thin on detail. The reporting excerpts do not name the astronauts who carried out the spacewalk, give its duration, or describe the hardware beyond calling the arrays next-generation and the final one an add-on. Those details are likely in the full articles from NASA, CBS News and Spaceflight Now, but they are not in what is summarized here.
What the reporting does establish is the shape of the story. A five-year modernization of the station's power system reached its final installation, on the 101st spacewalk in the station's history, and the crew's reaction was relief and satisfaction in a few words.
The next thing to watch is performance. Once the new arrays are fully activated and the station's output is measured, it will become clear whether the roughly 30 percent gain the project promised has materialized.
