Cots moot is ISS ends as planned & cots slips 3 years

A coming train wreck?

Further schedule delays could push the start of commercial flights toward 2020, which is the year in which ISS is scheduled for decommissioning. A three-year slip would render the entire program moot if the station program ends according to the current plan.

NASA wants to extend ISS operations until 2028, which a study has found to be technically feasible. The main goal is to complete research to help pave the way extended human missions to deep space. The station is also host to an increasing number of commercial microgravity experiments. However, it's uncertain whether the space agency's international partners—Russia, Europe, Japan, and Canada—will agree to the extension. Several of the partners appear to be more interested in pursuing new projects than in continuing an old one whose annual operating costs are high.
