 The crew on board then removed the batteries from Priroda and stored them in Progress M-31 for a destructive re-entry.During the last expedition to Mir in 2000, power loads were reportedly so high that the crew was not able to activate any of Priroda's payloads.Priroda, along with the other Mir components, were destroyed when the Mir station was de-orbited in March 2001, entering the Earth's atmosphere.
