Spektr (Template:Lang-ru; lit. Spectrum) was the fifth module of the Mir Space Station. The module was designed for remote observation of Earth's environment containing atmospheric and surface research equipment. Spektr also had four solar array which generated about half of the station's electrical power before June 1997.

During joint Russian-American program on board Mir Spektr was the living quarters for American astronauts until late June 1997

On June 25, 1997, the Progress M-34 spacecraft crashed into Spektr while maneuvering for a docking with the Kvant-1 module. The collision damaged one of Spektr's solar arrays and punctured the hull, depressurizing the 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. An "internal" spacewalk inside the Spektr module in August 1997 by cosmonauts Anatoly Solovyov and Pavel Vinogradov succeeded in restoring those connections by modifying the hatch them pass through in the closed position. In a second internal spacewalk in October they connected two of the panels to a computer system to allow them to be controlled remotely and align with the Sun. These modifications allowed power generation to return to approximately 70% of the pre-collision generation capability.

Spektr was left depressurized and isolated from the remainder of the Mir complex.
