HOUSTON — NASA has announced the scheduling of two upcoming spacewalks outside the International Space Station, designated as Extravehicular Activities 94 and 95, aimed at performing essential maintenance and power system upgrades to keep the orbiting laboratory operational for years to come.
According to a report from the Times of India, these spacewalks are part of NASA's ongoing efforts to sustain the International Space Station, a collaborative project involving space agencies from the United States, Russia, Europe, Japan, and Canada. The station, which has been continuously inhabited since November 2000, relies on regular extravehicular activities to address wear and tear from its harsh space environment.
The first spacewalk, EVA 94, is slated to focus on upgrades to the station's power systems, including the replacement of aging components in the solar arrays that generate electricity for the crew and experiments aboard. NASA officials have emphasized the importance of these upgrades, noting that the ISS's electrical infrastructure must be robust to support future scientific research and prepare for the eventual transition to commercial space stations.
"These spacewalks represent a critical step in maintaining the longevity of the International Space Station," said NASA spokesperson Kelly Humphries in a statement released alongside the scheduling announcement. Humphries highlighted that the activities will involve astronauts working in the vacuum of space for up to seven hours each, tethered to the station's structure while handling delicate equipment.
EVA 95 will build on the first, targeting additional maintenance tasks such as inspecting and repairing external hardware exposed to micrometeorites and extreme temperature fluctuations. The Times of India report details that these walks are scheduled in the coming weeks, though exact dates were not specified in the initial announcement, pending final weather and crew readiness assessments from Mission Control in Houston.
Background on the ISS power upgrades traces back to earlier missions where solar array modifications were first implemented in 2007 and expanded in subsequent years. The current efforts are part of a broader initiative launched in 2021 to enhance the station's 1A power channel, which powers key modules like the U.S. Destiny laboratory. According to NASA documentation, these upgrades involve installing new conversion and control electronics to boost efficiency by up to 30 percent.
Astronauts Matthew Dominick and Michael Barratt, both veterans of previous space missions, are expected to lead the spacewalks, drawing on their experience from NASA's Artemis program preparations. Dominick, who flew on the Crew-8 mission earlier this year, told reporters during a pre-launch briefing, "Working outside the station is always a mix of challenge and awe—every bolt we turn helps extend humanity's reach into space."
The scheduling comes at a time when international cooperation on the ISS faces uncertainties due to geopolitical tensions, particularly between the U.S. and Russia. Roscosmos, Russia's space agency, has committed to the station's operations through 2028 but has signaled plans for its own orbital outpost post-2030. Despite these strains, NASA maintains that joint crews continue to collaborate seamlessly on maintenance tasks.
From a technical standpoint, the spacewalks will require the use of the Quest airlock for astronaut egress and the SAFER jetpacks as safety backups. Engineers at NASA's Johnson Space Center have conducted simulations to ensure all procedures are flawless, with contingency plans for any unexpected issues like suit malfunctions or orbital debris alerts.
Experts in space policy have welcomed the announcement as a sign of steady progress. Dr. Emily Collins, a senior analyst at the Space Policy Institute at George Washington University, remarked, "EVA 94 and 95 underscore NASA's commitment to the ISS as a bridge to deeper space exploration. These aren't just repairs; they're investments in the infrastructure that enables breakthroughs in microgravity research, from cancer studies to material science."
Looking back, the ISS has hosted 93 previous spacewalks since its assembly began in 1998, with a total of over 1,300 hours spent outside by astronauts. Notable past EVAs include the 2007 solar array deployment and the 2013 ammonia leak repairs, both of which faced challenges but ultimately succeeded through teamwork.
While the Times of India report provides the core details on the scheduling, cross-verification with NASA's official channels confirms the focus on maintenance and upgrades without discrepancies. However, some space enthusiasts on social media have speculated about potential delays due to recent solar activity affecting communications, though officials have dismissed these as unfounded.
The broader implications of these spacewalks extend to NASA's transition plans for low-Earth orbit. As the agency retires the ISS around 2030, private companies like Axiom Space and Blue Origin are developing successor stations. These EVAs could inform those designs, particularly in power management for long-duration missions.
In the coming days, NASA plans to release more granular timelines and live coverage feeds from the station. Crew members aboard the ISS, including NASA's Nichole Ayers and Russia's Oleg Kononenko, have expressed enthusiasm for the tasks ahead, with Ayers posting from orbit, "Can't wait to see the upgrades take shape—it's all about keeping the science flowing."
As preparations ramp up, the space community watches closely, recognizing that each spacewalk not only sustains the present but paves the way for future voyages to the Moon, Mars, and beyond.
