NASA details research and station upgrades for SpaceX’s next cargo flight

NASA said on October 7 that its 35th SpaceX commercial resupply mission is targeting a launch no earlier than October 13 from Cape Canaveral Space Force Station in Florida. A Falcon 9 is set to carry a Dragon spacecraft with more than 6,300 pounds of supplies and equipment to the International Space Station, including new research projects and the final pair of roll-out solar arrays for the station’s power system.

The October 13 date is an earliest target, with the launch time still to be determined on NASA’s mission page. An independent October 4 report by 321 Daily likewise described the date as a target rather than a confirmed launch appointment. NASA’s September 17 advisory had given the broader target of no earlier than October; its new overview sets out more of the intended cargo and research.

What research will Dragon carry to the space station?

One experiment, LambdaVision-1, will test how to manufacture artificial retinas one thin layer at a time in microgravity. NASA says reduced settling could produce more uniform, stable layers and potentially improve implants. That is the purpose of the experiment, not evidence that an implant has restored anyone’s sight. The overview reports no result from this flight, which has yet to launch.

The Stellar Spheroids experiment will examine how three-dimensional human heart tissue models grow and function in microgravity. Researchers plan to assess whether that environment helps form advanced vascular networks. NASA describes more realistic disease models and larger-scale drug testing as possible longer-term uses; the mission has not established either outcome.

MINDS will study brain organoids, including mixed-cell ‘organoid villages’ designed to represent diversity among patients. The aim is to investigate inflammation associated with neurodegenerative diseases. NASA says the work may point researchers toward targets relevant to Alzheimer’s, Parkinson’s and multiple sclerosis. It has announced neither a treatment nor a clinical finding from this planned investigation.

Why the solar arrays and return flight matter

Dragon is also scheduled to deliver the final pair of International Space Station Roll-Out Solar Arrays. NASA says astronauts will install them during later spacewalks to complete an upgrade to the station’s power supply. The agency expects the added power to support station operations, including its eventual safe, controlled deorbit. Delivery on CRS-35 and installation afterward remain pending.

Other listed equipment includes a collapsible contingency urinal and support hardware for Artemis III, along with maintenance items for station systems. NASA says the flight will also carry support equipment associated with a Canadarm2 joint that failed and was replaced during a June 30 spacewalk. The returned joint is to undergo analysis on the ground. The overview does not establish the result of that examination.

NASA expects Dragon to dock autonomously at the space-facing port of the station’s Harmony module, with astronauts Anil Menon and Jessica Watkins monitoring its arrival. The agency estimates a stay of about a month, followed by a Pacific Ocean splashdown in mid-November. Those dates describe the current plan; neither docking nor return has taken place under this mission announcement.

How CRS-35 fits NASA’s cargo program

NASA’s Office of Inspector General traces the commercial resupply program to the agency’s shift away from building and operating its own transport vehicles after the Shuttle era. It says NASA awarded its first cargo contracts to two providers in 2008 and a second round in 2016 worth up to $14 billion. Buying flights from multiple providers was intended in part to give the station more than one route for supplies.

In its September account, the inspector general said Cargo Dragon, operating since 2012, was the only operating cargo vehicle in NASA’s commercial program able to bring freight back to Earth. Northrop Grumman’s Cygnus is expendable. That return capability matters for the planned glass samples and the Canadarm2 joint, both of which NASA says are intended for examination after the flight. The inspector general also identified reliance on Falcon 9 for both operating cargo vehicles as a program challenge.

The next confirmed milestones will be a launch time and, if the flight proceeds, liftoff and docking. NASA links its mission and station blogs from the CRS-35 mission page for updates. Its current material establishes the intended cargo and research questions, while leaving the launch, experiment findings, solar-array installation and return analysis for later reporting.
