the Russian Orbital Segment of the ISS carries no CMGs of its own. However, the proposed but as yet unbuilt Science and Power Module (NEM-1) would be fitted with several externally-mounted CMGs. NEM-1 would be installed on one of the lateral ports of the small Uzlovoy Module or Nodal Module scheduled for completion and launch at some time within the 2016–25 Russian programme. Its twin NEM-2 (if completed) would later be installed symmetrically on the other lateral UM port. On 24 February 2015, the Scientific and Technical Council of Roscosmos announced that after decommissioning of the ISS (then planned for 2024) the newer Russian modules would be detached and form the nucleus of a small all-Russian space station to be called OPSEK. If this plan is carried out, the CMGs on NEM-1 (and NEM-2, if built) would provide attitude control for the new Russian station. The proposed space habitat Island 3 was designed to utilize two contrarotating habitats as opposed CMGs with net zero momentum, and therefore no need for attitude control thrusters.
