Spektr was the fifth module of the Mir Space Station. On June 25, 1997, the Progress M-34 spacecraft crashed into Spektr while maneuvering for a docking with the Kvant-1 module.
The module was sealed off from the rest of the station to prevent depressurization of the entire Mir station, but required cutting off the power cables from Spektr’s solar panels, which had to be cut manually with fire axes.
