NASA Astronauts Anil Menon, Jessica Meir Complete ISS Spacewalk

Spacewalk Underway for Power Upgrades

NASA astronauts Anil Menon and Jessica Meir stepped outside the International Space Station (ISS) on Thursday to install critical mounting hardware. The spacewalk, which began in the early hours, is part of ongoing efforts to upgrade the station's power systems.

The duo worked on the 3B power channel, preparing it for future installation of new roll-out solar arrays. These arrays are designed to boost the station's electrical capabilities as demand grows.

Maiden Spacewalk for Indian-Origin Astronaut

For Anil Menon, this marked his first spacewalk. The Indian-origin astronaut, who was selected by NASA in 2017, has been aboard the ISS since earlier this year. His participation highlights the growing role of Indian-origin professionals in global space exploration.

Jessica Meir, a veteran of multiple spacewalks, provided guidance and support throughout the procedure. The pair worked meticulously, attaching the hardware to the station's truss structure.

Why the Upgrade Matters

The ISS has relied on its original solar arrays for over two decades. These arrays have degraded over time due to micrometeoroid impacts and thermal cycling. The new roll-out solar arrays, or ROSAs, are more compact and efficient, offering a significant boost in power generation.

Once installed, the new arrays will augment the existing ones, ensuring the station can support future scientific experiments and commercial activities. The mounting hardware installed Thursday is a crucial first step in this process.

Routine Yet Risky Operation

Spacewalks are among the most challenging tasks astronauts undertake. Even with rigorous training, the environment outside the ISS is unforgiving. Each movement must be deliberate, and every tool secured.

NASA had planned this spacewalk well in advance, with teams on the ground monitoring every step. The agency confirmed the successful completion of the primary objectives, though further details on the duration and exact timeline have not been fully disclosed.

Looking Ahead

With the mounting hardware in place, the next phase will involve delivering and installing the actual roll-out solar arrays. These are expected to arrive on a future cargo mission later this year.

For Menon, this spacewalk is a personal milestone, but for NASA, it's another step in extending the life of the ISS. The station, which has been continuously inhabited since 2000, is scheduled to operate until at least 2030.

As the agency prepares for future missions to the Moon and Mars, upgrades like these ensure the ISS remains a vital testing ground for technologies that will support deep-space exploration.
