SpaceX Cargo Dragon Delivers Research and Solar Arrays to ISS

NASA’s 35th contracted SpaceX Cargo Dragon resupply mission, designated CRS-35, completed an automated docking at the International Space Station on October 15, 2026, delivering over 6,300 pounds of supplies, scientific investigations, and hardware, Aviation Week reported.

Automated Docking at the Harmony Module Port

The robotic Dragon spacecraft successfully locked onto the space-facing port of the orbiting laboratory’s Harmony module.

Final Delivery of Roll-Out Solar Arrays

The primary hardware payload aboard the flight included the final two International Space Station Roll-Out Solar Arrays (iROSAs).

Microgravity Science and Medical Investigations

Scientific gear packed inside the unpressurized and pressurized sections targets multiple disciplines. The spacecraft delivered hardware designed to manufacture artificial retinas in microgravity to help restore vision on Earth, alongside 3D heart tissue models intended to advance large-scale drug testing. Additional cargo includes materials for studying glass formation in microgravity and brain organoids aimed at uncovering treatment pathways for neurodegenerative disorders such as Alzheimer’s, Parkinson’s, and multiple sclerosis.

Falcon 9 Launch and Pre-Dawn Visual Spectacle

Lifting off at 6:33 a.m. EDT on October 13, 2026, a SpaceX Falcon 9 rocket carried the Dragon cargo capsule aloft from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. The pre-dawn blastoff occurred 48 minutes before sunrise, creating a luminous, expanding plume of fuel exhaust that crystallized in the upper atmosphere. This phenomenon generated a widely visible “jellyfish cloud” across the United States East Coast, with observers from Georgia to New York capturing the display.

Orbital Timeline and Return Schedule

The Dragon spacecraft is scheduled to remain docked to the orbital complex for approximately one month. In mid-November 2026, the vehicle will detach, re-enter the atmosphere, and execute a parachute-assisted splashdown in the Pacific Ocean off the coast of California, returning time-critical research samples to investigators.
