NASA astronauts Anil Menon and Jessica Meir successfully completed a spacewalk outside the International Space Station (ISS), carrying out critical upgrades to the station's power infrastructure in preparation for the installation of new solar arrays.
The mission, which lasted 6 hours and 27 minutes, focused on modifying one of the ISS power channels to support the next generation of International Space Station Roll-Out Solar Arrays (iROSA). The upgrades are expected to enhance the station's power generation capacity while supporting long-term operations and future deorbit plans.
Anil Menon Completes First-Ever Spacewalk
The mission marked a major milestone for Anil Menon, who completed his first spacewalk, while veteran astronaut Jessica Meir carried out her sixth extravehicular activity (EVA).
The spacewalk officially began at 8:33 a.m. EDT (6:03 p.m. IST) on Thursday and concluded at 3:00 p.m. EDT (12:30 a.m. IST Friday), becoming the 281st spacewalk conducted in support of the International Space Station.
Working outside the ISS, the astronauts exited through the Quest airlock and performed structural modifications on the station's Starboard 6 truss, specifically targeting the 3B power channel.
ISS Upgrades to Support New Solar Arrays
The astronauts installed new mounting hardware that will enable the future deployment of International Space Station Roll-Out Solar Arrays (iROSA).
According to NASA, the new solar arrays will significantly improve the station's power generation capabilities, ensuring reliable electricity for onboard systems and supporting future mission requirements.
Since 2021, astronauts have already installed six iROSA solar arrays, with two additional arrays scheduled for delivery and installation later this year.
Critical Cabling and Insulation Installed
During the mission, Menon worked from an articulating portable foot restraint mounted on the station's truss, providing a stable platform to complete the installation work.
The crew also routed electrical cables that will connect the future solar arrays to the station's 3B power channel before covering structural components with multi-layer insulation to protect them from the harsh conditions of space.
These upgrades are considered essential for extending the ISS's operational capabilities while supporting NASA's long-term transition plans.
Memorable Moment During the Spacewalk
During a brief pause in operations, Jessica Meir pointed out the Moon to Menon.
After spotting it, Menon joked about humanity's future in space, saying he could "see a future moon base there," offering a light-hearted moment during the demanding mission.
Three ISS Spacewalks Scheduled This Month
The successful mission marks the first of three planned spacewalks for Expedition 75 during August.
The next EVA, scheduled for August 13, will focus on replacing a Space-to-Ground communications antenna, a key component used to transmit data between the ISS and NASA's Mission Control in Houston.
A third spacewalk on August 25 will involve connecting additional power and data cables, supporting future deorbit preparations, and replacing navigation hardware used for spacecraft docking.
The latest mission represents another important step in maintaining the International Space Station while preparing it for the next phase of its operational life.
