December 31: Russia to Split ISS, Recycle Modules for ROS Build
Russia ISS separation plan takes shape as Roscosmos prepares to detach its ISS segment and run it as the Russian Orbital Station (ROS) after retirement. Reports cite a 6,089 billion ruble budget, trading a clean-sheet build for lower upfront spend but higher technical risk. For investors in Japan, this move could reshape timelines for ISS deorbit around 2030 and impact U.S. commercial stations and deorbit vehicle work. We break down risks, milestones, and where Japan’s supply chain may feel it most.
What Russia is proposing and why it matters
Russia intends to split the ISS, keep its segment in orbit, and grow it into ROS with new modules added over time. The reported program cost is 6,089 billion rubles, a shift from building a fully new outpost. The plan reduces initial cash needs but loads execution risk. Early details are covered by Forbes Japan.
Key hardware from the current Russian segment would continue operating, while power, propulsion, and science capacity expand through incremental launches. Reuse shortens the gap between ISS retirement and independent operations. Yet aging systems raise reliability questions, and upgrade pacing will set how much research, cargo, and crew throughput ROS can support in the first years.
Splitting a complex, interdependent station demands careful work on power, attitude control, and docking reconfiguration. Safe undocking, rerouting of thermal and electrical loads, and establishing stable orbits are central tasks. Unplanned outages or control issues could delay both ROS readiness and U.S. segment end-of-life steps, increasing schedule and insurance risk for all parties.
Global impacts: ISS deorbit 2030 and private stations
NASA targets an ISS deorbit around 2030 using a dedicated vehicle, with interim support from existing propulsion assets. Crew Dragon reboost demonstrations showed that commercial spacecraft can assist with altitude management. Timing and safety steps for final disposal remain key watchpoints.

If resources shift to separation tasks, schedules for U.S. commercial LEO stations could slip. Certification flows, cargo cadence, and crew rotations may be reprioritized. For investors, this raises questions on revenue timing, module readiness, and insurance costs. Any delay in transition services could extend ISS operations spending while pushing out near-term commercial microgravity demand.
Why this matters to Japanese investors
Japan’s component makers, materials providers, and ground service firms could see changing demand as partners rebalance priorities. Opportunities may rise in avionics upgrades, thermal systems, and robotics support for long-life operations. Conversely, sanctions and export controls can limit routes to revenue. Firms with diversified customers across U.S., Europe, and Japan appear better placed.
As orbits and logistics change, demand for reliable cargo and tech-demo flights may grow. Japan’s ecosystem can benefit through testing new life-support elements, sensors, and on-orbit inspection tools aligned to commercial stations. Service revenue may shift from ISS-focused payloads toward transition services, debris tracking, and in-space validation that de-risk future station contracts.
Key watchpoints and investment scenarios
Track 2025–2027 signals: separation design reviews, health reports on reused modules, first ROS-specific hardware launches, and progress on a U.S. deorbit vehicle. Watch commercial station award updates, insurance pricing for LEO operations, and crew transport capacity. Any slip in these markers could cascade through launch manifests and experiment backlogs.
Base case: phased separation, early ROS ops, and orderly ISS end-of-life near 2030. Downside: technical setbacks cause delays, higher costs, and extended ISS maintenance. Upside: smooth split, faster module upgrades, and earlier commercial LEO services. Portfolio tilt favors suppliers with multi-market exposure and proven flight heritage.
Final Thoughts
For investors in Japan, the Russia ISS separation plan is a practical pivot that lowers initial spending but adds execution risk. The path to ROS depends on safe detachment, reliable legacy systems, and steady upgrades. On the other side, the U.S.-led segment aims for a 2030 deorbit, with commercial stations and a dedicated deorbit vehicle shaping the handover. Near term, we would track engineering reviews, module launches, insurance rates, and logistics capacity. Exposure to diversified space supply chains, testing services, and ground infrastructure can offer balanced upside. Position size should reflect schedule risk and the possibility of extended ISS operations. Discipline on catalysts and risk controls is essential.
FAQs
Russia plans to detach its ISS segment and operate it as the Russian Orbital Station, adding new modules over time. The approach reuses existing hardware to cut upfront costs but raises technical and schedule risks. Investors should watch engineering milestones and timelines that affect logistics, insurance, and station service revenues.
ROS is a planned outpost built by continuing operations of Russia’s current ISS segment and expanding with new modules. It aims to sustain research, power, and propulsion independently. Progress depends on safe separation, reliable legacy systems, and timely launches that increase capacity for crew, cargo, and science.
Target deorbit is around 2030 for the U.S.-led side, supported by a dedicated vehicle. Russia’s split adds coordination tasks but does not change the goal. Delays in separation or hardware readiness could shift dates. Investors should watch deorbit vehicle progress and station health reports for schedule clues.
Crew Dragon reboost demonstrations showed commercial spacecraft can help adjust station altitude, aiding operations until final disposal. This capability supports flexibility while a dedicated deorbit vehicle is prepared. It does not replace the deorbit craft but can reduce risk and maintain safe orbits during the transition period.
Favor firms with multi-customer exposure across the U.S., Europe, and Japan, plus proven flight heritage. Look for suppliers in avionics, thermal control, materials, and ground services tied to LEO transition work. Manage risk with staged entries, tracking technical milestones, insurance costs, and contract updates from station programs.
