As the International Space Station nears its scheduled retirement in 2030, the NASA panel warns of ISS risks that could jeopardize ongoing operations and public safety. Speaking at an April 17 public session, the Aerospace Safety Advisory Panel (ASAP) expressed serious concerns about aging systems, structural vulnerabilities, and a widening budget gap that threatens to derail NASA’s low Earth orbit transition strategy.
Cracks in the ISS Raise Safety Alarms
One of the panel’s top concerns is the persistent issue of cracking within the PrK vestibule of the station’s Zvezda module, a longstanding component of the Russian segment. Despite ongoing efforts between NASA and Roscosmos, no definitive solution has emerged to explain or repair the cracks.
“The ISS has entered the riskiest period of its existence,” said ASAP member Rich Williams, citing this structural weakness as one of the panel’s highest concerns.
Procedures have been put in place to limit pressure on the affected vestibule, but the underlying problem remains unsolved.
Budget Shortfalls Fuel Cascading Risks
The NASA panel warns of ISS risks that stem not only from hardware concerns but also from a budget gap that undermines critical functions. The agency allocated just under $1 billion for ISS operations and maintenance in 2024 — a figure the panel sees as insufficient when compared to escalating needs.
“All of these risks are actually a derivative of this budget shortfall,” Williams explained.
ASAP fears that funneling money into future projects like the U.S. Deorbit Vehicle (USDV) and commercial station support may strip the ISS of essential operational funds.
Deorbit Plan Delays Spark Emergency Fears
NASA’s planned method for safely deorbiting the station involves the USDV, a project now under development by SpaceX. But ASAP raised a red flag: if the station must be deorbited before the USDV is ready, the risks to public safety from falling debris could escalate drastically.
“The risk to the public from ISS breakup debris will increase by orders of magnitude,” Williams warned.
Logistics Setbacks Compound the Problem
Supply chain and resupply vehicle issues are also undermining ISS operations:
- Sierra Space’s Dream Chaser has delayed its inaugural cargo flight until at least late summer.
- Northrop Grumman canceled its NG-22 Cygnus mission after damage was sustained during shipping.
These issues have disrupted schedules for delivering spare parts and critical life support systems.
Final Years Require Full Support, Not Less
The panel emphasized that nearing the end of the ISS’s life cycle is no reason to downscale investment or attention.
“As programs near final phases, it is tempting to assume fewer resources are needed,” said Williams. “For the ISS, it is critical to maintain adequate budget and resources until the vehicle is safely reentered.”

Conclusion
As the NASA panel warns of ISS risks, the message is clear: the station’s final years may be its most dangerous. Ensuring a safe and controlled deorbit, while maintaining robust operations, will require strategic focus, urgent funding decisions, and international cooperation to safeguard both astronauts and the public.
