NASA asks for 'space tug' ideas to deorbit ISS in fiery finale
A spaceship will safely bring down the U.S. segment of the ISS after the program concludes in 2030.
www.space.comHere’s the latest on ISS decommission as of 2026.
-
NASA has publicly committed to retiring the International Space Station by 2030, with a controlled deorbit by around 2031, and the transition plan emphasizes moving microgravity research to commercial low-Earth orbit (LEO platforms) after the ISS winds down. This plan has been reaffirmed in multiple NASA communications and transition FAQs.[6][7][9]
-
The retirement process is planned to be gradual and coordinated among international partners (NASA, Roscosmos, ESA, JAXA, CSA). Key elements include a deorbit vehicle contract (SpaceX) to execute a safe reentry over the Pacific and a staged handover to commercial stations, aiming to minimize gaps in U.S. access to microgravity research.[3][9][6]
-
Current milestones cited in late 2024–2025 updates include preparing for end-of-life operations, ensuring critical capabilities (such as Russian segment propellant logistics) through the transition, and pursuing multiple commercial station candidates (Axiom Space, Starlab, Orbital Reef, Haven-1) to replace or supplement ISS research capabilities post-2030.[4][3]
-
Public reporting in 2025 highlighted ongoing discussions about the deorbit approach, with the USDV (Deorbit Vehicle) being developed under NASA contracts to enable a controlled splashdown, while NASA continues to monitor readiness and safety through 2030–2031.[4][6]
-
Typical timelines project the deorbit sequence to begin after crew departs, with a natural orbital decay phase complemented by a dedicated deorbit maneuver, culminating in a controlled reentry over a remote ocean region (e.g., Point Nemo) as the final disposal step.[9][6]
Illustrative note
- The retirement isn’t “scrapping” in place; it’s a managed transition toward commercial LEO platforms that can carry out similar research and activities, while freeing NASA to focus on deeper space missions such as Artemis and crewed exploration beyond Earth orbit.[6][9]
