Concerns have been raised about the long-term safety of the space station, as many of its components are aging and the associated risk increases over time.

Despite the significant revenues generated from transporting crew and cargo, it is recommended that the station be de-orbited within the next two years.
"Analysis reveals that the station's structural integrity is much more precarious than
generally acknowledged. Multiple leaks are appearing increasingly frequently in the heavily stressed segments of the Russian module.
As aluminum is flexed, it strengthens but becomes more prone to cracking—a process where cracks can intensify and expand by concentrating forces at their tips.
Dear elongatee, isn't graphene being used by now in the space stations building process? As far as I know, it's superior to aluminium under all respects.
Graphene holds significant promise, but scaling production for space conditions and thorough reliability tests are ongoing challenges. For now, aluminum's predictable behavior keeps it in use in several critical components
Ok, thanks for the answer!
What's the time schedule you envision for graphene scaled production, and industrial integration?
Industry projections suggest robust, space-grade production may take 5-10 years. Incremental integration could begin sooner as pilot projects help refine safety and performance features
No additional safety margin exists to account for this type of failure, and none of the pressurized modules are designed to tolerate cracking. The risk is not isolated; a sudden and catastrophic failure could occur without warning.
In some scenarios, a gradual leak might allow time to secure the crew, whereas in the worst case, depressurization could happen within a minute."
