NASA Announces Live Coverage for Trio of Upcoming International Space Station Spacewalks

WASHINGTON — NASA is preparing for a demanding month of orbital maintenance, announcing comprehensive live coverage for three upcoming spacewalks scheduled throughout August. Astronauts aboard the International Space Station (ISS) will venture outside the safety of the orbiting laboratory to perform critical hardware upgrades designed to sustain and enhance the station's operational capabilities.

To outline the specific objectives, timelines, and astronaut assignments for these complex extravehicular activities (EVAs), NASA will host a preview news briefing at 2 p.m. EDT on Thursday, July 30. The press conference will broadcast live from the Johnson Space Center in Houston on NASA Television, the NASA app, and the agency's official website.

Upgrading Orbital Infrastructure

The primary focus of the upcoming excursions centers on the modernization of the space station's power grid and communication systems. Over successive spacewalks, the international crew will focus on three core objectives:

• Solar Array Upgrades: Preparing the station's truss structure for the installation of new ISS Roll-Out Solar Arrays (iROSAs) to bolster the aging power system.
• Communications Overhaul: Replacing a degraded communications antenna to ensure high-rate telemetry and uninterrupted data flow between the station and ground control.
• Infrastructure Cabling: Routing and connecting critical power and data cables to support ongoing space station operations and future commercial modules.

The addition of the newer roll-out solar arrays is particularly critical. While the station's original rigid solar wings have reliably powered the facility for over two decades, they have naturally degraded over time. The newer, more efficient iROSA wings will mount directly over the legacy arrays, boosting the station's overall power generation capacity by up to 30 percent.

Ensuring Operational Longevity

These maintenance tasks highlight the ongoing challenges of managing a human outpost that has been continuously occupied for nearly 25 years. The integration of upgraded power and communications systems is essential not only for current operations but also for supporting a growing roster of international scientific investigations.

"These upcoming EVAs represent the meticulous, ongoing effort required to keep a multi-decade-old laboratory functioning at the peak of modern technological capability," said a senior ISS Program representative. "Every cable routed and every antenna replaced directly translates to more reliable science and paves the way for the commercial future of low-Earth orbit."

Media and Broadcast Information

The July 30 briefing will feature key mission representatives, including ISS program managers and spacewalk flight directors, who will provide detailed step-by-step breakdowns of each scheduled excursion.

Live coverage of the actual spacewalks in August will begin several hours prior to the crew exiting the hatch, allowing viewers to follow the rigorous suit-up and depressurization protocols. Media representatives wishing to participate in the preview news conference and submit questions must register with NASA's newsroom in accordance with standard accreditation guidelines.
