Resurs-F1M Missions

Resurs F1M was an minor evolution of the Resurs-F1. It allowed on-orbit life to be extended from the original fourteen days to 25 days.

To achieve this, it may have been fitted with Resurs-F2's solar panels, attached to its orbit adjustment engine module. Only two missions were ever flown, maybe using up the final pair of Resurs-F1 flight articles.
