Future Post ISS Space Station


The OPSEK follow on space station complex as presently conceived for development after the ISS program is planned around either the in development new Russian segement module with the First being the MLM, FGB-2 Module “Functional Cargo Block” followed by the Common Node Module NMUM) & the MLM Air Lock Module and the Science & Power Modules SPM-2 and SPM-2 (NEM-1, & NEM-2) It may also be associated with various free flyer modules for materials processing and national security needs. The present plan makes these modules a new part of the ISS program but in the final version it may be a new set of these modular designs updated to the post 2020 time frame as a second generation version of the station elements.

First MLM, FGB-2 Module “Functional Cargo Block” [OPSEK]

The first MLM module with the European Robotic Arm (ERA) is to be launched on the Proton-M booster which is expected to resemble the Zarya module of ISS as the starting block. Basically that first block module is believed to be nearly completely built and will be available for a scheduled flight in 2012 based on the present planning. It mass is about 20,700 kilograms with maximum diameter of 4.1 meters and a maximum diameter of 13.2 meters with an internal volume of 71 meters cubed. It is planned to carry up to 60 experiments to be performed on board. This first of new larger modules will require the removal of the Pirs module from it docking port and its subsequent planned re-entry to destruction.

Common Node Module NM (UM) & the MLM Air Lock Module [OPSEK]

The intent is to also add a smaller MLM airlock module to the Common Node Module NM (UM). That multiple docking port module launched on a Soyuz booster with Progress M-UM spacecraft carrying a multiple docking port like that of MIR for attachment to the front earth facing MLM, (FGB-2) Module. It is provided with the docking adapter attachment point for the larger modules. The node provides for the existing Soyuz docking berth directly facing earthward as well as a potential EVA Airlock. Progress M-UM weighs 4,000 kilograms and an internal volume of 14 meters cubed and is presently scheduled for launch in 2013.

Science & Power Modules SPM-2 and SPM-2 (NEM-1, & NEM-2)

The proposed last two (SPM-2 and SPM-2) long cylindrical scientific and power modules are tentatively planned for launch on the Proton–M booster in 2014 and 2015 if the funding is available from commercial and Russian, Federal Space Agency (“Roskosmos”) government sources. The intent of the last two NEM modules numbers 1 & 2 is to provide both power and large research laboratory space for the station and its partners as well as attaining the original purpose of the cancelled for lack of funding habitation Science and Power-supply platform (NEP) module. The larger modules are designed to provide large radiator surfaces for heat dissipation and large solar arrays on the opposite ends of the of the two modules docked 180 degrees from one another horizontally under the existing Russian ISS modules to the earth facing multiple docking port in front of the new MLM, FGB-2 Module Zarya like module. The NEM modules have a general mass of 20,000 kilograms with a maximum diameter of 4.1 meters with an approximate lengthy of 25.3 meters and possibly up to 100 meters cubed internal volume of which 12 meters cubed is habitable volume with 2,500 kilograms cargo capacity.

The October 22, 2005, Russian Federation government approved of FSP 2006-2015 expanded spaceflight development decision was based on the re appearance of the Soviet era like fiscal Five Year Plan (2006-2010) and the next five year plan called the five year Forecast Plan (2011-2015) cycle to Russian Federal Space Agency developments. Soon the Russian Federal Space Agency will replace the present FYP with the 2011-2015 five year plan followed by the 2016-2020 forecast plan.

It has already been stated by the Russian’s that as long as the U. S. supplies power cheaply as a trade off there will be no need to build the last modules for now except in the new post ISS space station program of Russia called OPSEK. Truly this leaves in doubt the fate of these modules in the new Russian Federal Space Agency five year plans of 2011-2015 and 2016-2020. Prime Minister Putin on July 19, 2010 suggested that the completion of the Russian segment of ISS should be accomplished in 2015.

Whether this new future space station OPSEK comes to fruition depends in large part on the economic reality of the Russian economy to support its fulfillment in the face of the world economic crisis now and in the future.
