China shares ambitious plans to double its space station as the ISS approaches the end of its life cycle

This is a most excellent place for technology news and articles.
I don't really understand how the entire ISS could be "end of life cycle." Aren't there a bunch of different modules of different ages? And anyway, the oldest modules are 24 years old that is nothing with proper maintenance, there are 50 year old trains still in operation daily.
Space trains fall under a different regulating authority than space stations, unfortunately.
