Two Russian Cosmonauts,Sergey Ryzhikov and Alexey Zubritsky,successfully concluded a seven-hour spacewalk outside the International Space Station (ISS) today,October 28,2025. The excursion focused on exterior maintenance work on the Nauka multipurpose laboratory module, marking the pair’s second spacewalk together in just two weeks.

The Cosmonauts worked diligently on the exterior of the Nauka module, addressing critical tasks essential for the continued operation of the ISS. Their actions contributed directly to the station’s ongoing scientific research and operational capabilities. This spacewalk comes amidst a period of heightened activity at the ISS, which continues to serve as a unique orbital laboratory for international collaboration.

According to NASA,the Expedition 73 commander,sergey Ryzhikov,and cosmonaut Alexey Zubritsky,donned their Orlan spacesuits and exited the airlock at approximately 8:03 a.m. EDT. They meticulously executed a pre-planned set of objectives, demonstrating precision and efficiency in the challenging surroundings of space.

Spacewalk Details and Objectives

The primary focus of the spacewalk was to perform inspections, maintenance, and perhaps install new components on the Nauka module. This included a review of external systems and procedures designed to proactively maintain optimal function.Precise tasks where not instantly disclosed to maintain operational security, but NASA indicated all goals were achieved.

Did You Know? Spacewalks, technically referred to as Extravehicular Activities (EVAs), require extensive preparation, including suit checks, equipment preparation, and procedure reviews. Each spacewalk is a carefully choreographed event, necessitating collaboration between astronauts, cosmonauts, and mission control teams.

The Importance of ISS Maintenance

The International Space Station, a collaborative project involving multiple international space agencies, constantly requires upkeep and repair to maintain its operational status. Spacewalks play a vital role in ensuring the long-term viability of the station and its ability to support groundbreaking research in microgravity. Regular maintenance helps to prevent unexpected issues and minimizes the risk of system failures.

Pro Tip: The harsh conditions of space-extreme temperatures, radiation, and the constant threat of micrometeoroid impacts-make maintaining the ISS an ongoing technical challenge. Spacewalks are inherently risky but are essential for the continued success of the program.

The prosperous completion of this spacewalk underscores the continued commitment of international partners to the ISS program. As the station approaches its third decade in orbit, ongoing maintenance and upgrades remain crucial for maximizing its scientific return and ensuring a safe and productive environment for its crew.
