What's Happening?
NASA is set to conduct its first spacewalk of 2026 on January 8 to prepare the International Space Station (ISS) for the installation of its seventh ISS Roll-Out Solar Array (IROSA). The spacewalk will
be carried out by ISS Expedition 74 commander Mike Fincke and astronaut Zena Cardman. The new solar arrays are part of an ongoing effort to augment the station's power supply, originally provided by four pairs of solar arrays installed between 2000 and 2009. The new IROSAs will enhance the station's power capacity, supporting life support and scientific research activities.
Why It's Important?
The installation of the new solar arrays is critical for extending the operational life of the ISS, which has been continuously staffed for over 25 years. The additional power capacity will support ongoing scientific research and technology development, which are essential for future space exploration missions. Moreover, the upgraded power system will play a vital role in the planned deorbit of the ISS in 2030, ensuring a safe and controlled descent. This upgrade reflects NASA's commitment to maintaining the ISS as a hub for international collaboration and scientific advancement.
What's Next?
Following the initial spacewalk, NASA plans additional spacewalks to complete the installation of the seventh and eighth IROSAs. These upgrades will ensure the ISS remains a viable platform for research and international cooperation until its planned deorbit. NASA is also working on transitioning ISS operations to commercial space station operators, which could lead to a more diverse and competitive low-Earth-orbit economy. This transition will require careful planning and collaboration with international partners and commercial entities.
