NASA’s Grand Retirement Plan: Seeking Deorbit Craft for Space Station’s Safe Descent

The International Space Station is pictured from the SpaceX Crew Dragon Endeavour throughout a fly around of the orbiting lab that took location following its undocking from the Harmony modules space-facing port on November 8, 2021. Considering that 1998, five area agencies (the Canadian Space Agency, the European Space Agency, the Japan Aerospace Exploration Agency, the National Aeronautics and Space Administration, and the State Space Corporation “Roscosmos”) have operated the International Space Station, with each responsible for handling and managing the hardware it supplies. The United States, Japan, Canada, and the taking part nations of ESA (European Space Agency) have committed to operating the station through 2030, and Russia through at least 2028.
At the conclusion of the International Space Station program, the station will be deorbited in a controlled way to prevent populated locations.

NASA looks for proposals for a brand-new spacecraft, the USDV, to safely deorbit the International Space Station upon its retirement, prioritizing flexibility and safety in the transition.
NASA has launched a demand for proposal from U.S. industry for the U.S. Deorbit Vehicle (USDV), a spacecraft suggested to securely deorbit the International Space Station as part of its organized retirement.
To maximize worth to the federal government and boost competitors, the acquisition will enable offerors versatility in proposing Firm Fixed Price or Cost Plus Incentive Fee for the Design, Development, Test and Evaluation stage. The remainder of the contract will be Firm Fixed Price.

International Cooperation and the ISS
Considering that 1998, five area agencies (the Canadian Space Agency, the European Space Agency, the Japan Aerospace Exploration Agency, the National Aeronautics and Space Administration, and the State Space Corporation “Roscosmos”) have actually operated the International Space Station, with each accountable for handling and controlling the hardware it offers. The station was created to be synergistic and counts on contributions from throughout the collaboration to operate. The United States, Japan, Canada, and the taking part nations of ESA (European Space Agency) have actually devoted to running the station through 2030, and Russia through at least 2028.

Future Plans and Safety Measures
At the conclusion of the International Space Station program, the station will be deorbited in a controlled way to prevent inhabited areas. The safe deorbit of the International Space Station is a shared obligation of all five area agencies through partner contributions based on mass percent ownership by firm. In the future, the United States plans to shift its operations in low Earth orbit to commercially-owned and -run platforms to ensure ongoing access and presence in area for research, innovation development, and worldwide collaboration.
Advancement of the U.S. Deorbit Vehicle
In a years-long effort, NASA and its partners studied deorbit requirements and formerly developed an initial method and action plan that evaluated making use of multiple Roscosmos Progress spacecraft to support deorbit operations. These efforts now suggest a brand-new spacecraft option would provide more robust capabilities for responsible deorbit. To initiate development of this brand-new spacecraft, NASA launched the request for proposal.
The USDV is concentrated on the last deorbit activity. It will be a new spacecraft design or adjustment to an existing spacecraft that needs to function on its first flight and have adequate redundancy and abnormality healing capability to continue the critical deorbit burn. Just like any development effort of this size, the USDV will take years to develop, test, and accredit.
