NASA's second spacewalk of 2025 is set to begin today, with two astronauts tasked with retrieving hardware from the exterior of the International Space Station (ISS). This spacewalk, US EVA 92, will be carried out by NASA astronauts Sunita Williams and Butch Wilmore. The pair is scheduled to begin their work on January 30 at approximately 8 am. EST (5 pm IST).

This event marks a significant milestone in space exploration, as it will be the 274th spacewalk conducted outside the ISS. It also carries personal significance for Williams, who is poised to make history. With the successful completion of this spacewalk, Williams will surpass the long-standing record of 60 hours and 21 minutes set by Peggy Whitson, a retired NASA astronaut and biochemist. Whitson’s record was achieved over the course of 10 EVAs (extravehicular activities), and Williams’ achievement will establish her as the new leader in cumulative spacewalking hours for female astronauts.

Live Coverage Of Sunita Williams’ Spacewalk

For space enthusiasts and viewers worldwide, the live coverage of this historic spacewalk will begin at 6:30 am EST (5 pm IST) on NASA’s streaming platforms, as well as on Space.com. This livestream will allow audiences to witness the exciting events unfold as Williams and Wilmore work outside the station. Their primary mission is to retrieve critical hardware and perform maintenance tasks on the exterior of the ISS.

The live coverage of NASA's spacewalk begins at 5 pm IST, with the spacewalk itself starting at 6:30 pm IST. The entire spacewalk, lasting 6.5 hours, will be livestreamed by NASA.

Sunita Williams To Conduct Critical Microbial Research

Sunita Williams’s ninth spacewalk carries out crucial tasks for the International Space Station (ISS). She will remove a Radio Frequency Group Antenna Assembly, a critical component for upgrading the station's communication systems, ensuring better efficiency and reliability. Williams will also collect material samples for microbial analysis, aiding scientific studies to understand how microbes interact with the space environment. These studies are essential for the sustainability of future human missions to Mars and beyond, helping protect astronauts from potential biological threats in space.
