Priroda was launched on April 23, 1996, on a Proton rocket. After reaching orbit, an electrical connector failure caused the amount of power available on Priroda to be cut in half. Due to the electrical problem, Priroda would only have one attempt at docking before power would be lost. This caused some concern for ground controllers because most other modules failed to dock on their first attempt. However, Priroda docked with no problems on April 26. After being moved to its permanent location at the +Z docking port on the base block, Priroda was connected to the rest of the station's electrical system, which allowed it to run off power from solar arrays on other modules. The crew on board then removed the batteries from Priroda and stored them in Progress M-31 for a destructive re-entry.
