SpaceX Launches 6,300 Pounds of Cargo and Final Solar Arrays to ISS

SpaceX successfully launched its 35th Commercial Resupply Services (CRS) mission to the International Space Station (ISS) on Tuesday, Oct. 13. A Falcon 9 rocket lifted off from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida at 6:35 a.m. EDT (1035 GMT), according to Space.com. The mission, designated CRS-35, carries 6,300 pounds (2,860 kilograms) of supplies and scientific hardware to the orbiting laboratory.

Final Solar Arrays and Power Upgrades

A primary component of the cargo is the final pair of International Space Station Roll-Out Solar Arrays (iROSAs). According to Starlust, these arrays are designed to complete the station’s power system upgrade and boost the electricity available for research, operations, and the station’s safe, controlled deorbit. The arrays are built by Redwire Space, as reported by Ascendants.in. Each array is designed to generate more than 20 kilowatts of electrical power and operate for more than a decade.

Astronauts will install the units during spacewalks planned for late autumn, according to Anadolu Agency. The technology traces back to a 2017 demonstration during the CRS-11 mission. Gaurang Patel, operations integration manager for NASA’s Low Earth Orbit Program, stated during a post-launch broadcast, "It’s been quite the journey," referring to the years of development since the initial demonstration.

Scientific Research and Medical Experiments

The Dragon spacecraft is carrying equipment for more than 40 scientific investigations, according to Ascendants.in. NASA officials wrote in a launch preview on Oct. 7 that the capsule "will deliver hardware to manufacture artificial retinas in microgravity to help restore vision on Earth and 3D heart tissue models to advance large‑scale drug testing on future missions."

The mission also includes materials to study how a new type of glass forms in microgravity. Dr. Liz Warren, NASA’s deputy chief scientist within its ISS Office, explained that these materials could have unusual physical and optical characteristics. "New types of glass like these could advance optics and electronics on Earth and supports space exploration with stronger, lighter, radiation-resistant, or higher-performing glass," Warren said during a prelaunch press conference. Additionally, the cargo includes brain organoids that could reveal treatment targets for neurodegenerative diseases such as Alzheimer's, Parkinson's and multiple sclerosis.

Reusable Hardware and Return Trip

The Falcon 9 first-stage booster, identified as B1096, completed its eighth flight, according to Ascendants.in. The booster landed at Landing Zone 40 approximately seven and a half minutes after liftoff. The Dragon capsule, designated C211, is making its fourth flight, having previously supported missions CRS-26, CRS-29 and CRS-33, according to Coinpaper.

Dragon is scheduled to dock autonomously with the space-facing port of the ISS Harmony module at around 11 a.m. EDT (1500 GMT) on Thursday, Oct. 15. The spacecraft will remain attached to the station for about a month before returning to Earth. According to Space.com, SpaceX's Dragon is the only currently operational freighter that can carry cargo in the downward direction, while other freighters like Russia's Progress and Northrop Grumman's Cygnus XL are expendable.

Why it matters

The CRS-35 mission delivers the final components needed to upgrade the ISS power infrastructure, a process that began with a technology demonstration nearly a decade ago. The arrival of the final solar arrays ensures the station has sufficient power for ongoing research and its eventual controlled deorbit. The mission also continues the flow of scientific experiments that support medical and materials research on Earth.
