A controlled deorbit is crucial to prevent any large debris from crashing unpredictably on Earth’s surface. SpaceX’s U.S. Deorbit Vehicle (USDV) will play a vital role in this mission.
Developing the USDV
SpaceX will develop the USDV over several years, ensuring it meets the stringent requirements for this delicate task.

The spacecraft will be designed to bring the ISS back to Earth safely, minimizing risks to human life and property. Testing and fine-tuning will be key aspects of this development phase.
International Collaboration
NASA isn’t alone in this endeavor. Canada’s CSA, Japan’s JAXA, and the European Space Agency (ESA) have all committed to supporting the ISS until 2030.
