Priroda

 1996-023A

---

The final Mir module was 77KSI Priroda (77KSI No. 174-01). Originally scheduled for 1992, it was finally launched in Apr 1996. Priroda did not have solar panels, so there was some concern when one of two electrical systems failed, but the short three-day rendezvous and docking was successful. The mass of Mir now stood at 128.98 tonnes. Mass of Priroda at EOI was 19470 kg, at rendezvous with Mir it was 18630 kg.

The day after docking, the Lyappa arm was used to transfer the module to the +Z port. After the hatch was opened, the EO-21 crew began sealing the battery systems in bags and transferring them to Mir for later disposal in a Progress.
