The lower their launch costs, the more it may make sense to deorbit and replace entire trains rather than individual satellites within trains. If that is the case, it doesn't help much that the average life span is a bit more than 5 years. When a train of satellite starts to degrade, they may just deorbit the entire train, even if some of the satellites in the train could still operate for a while. Or am I getting that wrong?
