25 years from the launch of the Spektr module

May 20, 2020

On May 20, 1995 the Proton-K launch vehicle carrying the Spektr research module was launched from the Baikonur Launch Site under the assembly program for the world's first multi-module manned orbital complex Mir.

On June 1, 1995 after a 12-day free flight the module automatically approached the axial docking port of the core module of the Mir orbital complex. Then Spektr using a remotely-controlled manipulator was relocated to the lateral port of the core module and became part of the orbital complex. In this period the international crew of the 18th main expedition consisting of cosmonauts V.N.Dezhurov, G.M.Strekalov and NASA astronaut N.Tagard worked aboard at the station.

The Spektr module (index 77KSO) was developed under the leading role of NPO Energia (now S.P.Korolev RSC Energia) on the basis of the functional cargo compartment of the transport logistics vehicle. The Spektr scientific equipment was designed to observe the Earth and search for natural resources, study the upper atmosphere, near-Earth space and the impact of space environment on various materials. Under the agreement with NASA the US biomedical experiment equipment to study conditions of human long-duration stay in space was first installed on the Spektr module. This experience was supposed to be used for the future International Space Station. The module was also characterized by a unique system of high-power solar panels which became an important electric power supply for the entire orbital complex.

The successful operation of the Spektr module in low Earth orbit continued until June 1997, when it was damaged due to a collision with the Progress M-34 cargo vehicle during development of the remote piloting control mode when the re-approach and docking experiment was implemented. Further repair activities eventually made it possible to restore the power supply utilities, but the depressurized module never returned to its nominal flight mode. It remained uninhabited as part of the Mir orbital complex for the entire remaining life providing power to the station until its deorbit on March 23, 2001.
