NASA has formally selected SpaceX to build a spaceship that will deorbit the International Space Station (ISS) in 2030, marking an important milestone in space exploration.
The $843 million contract will go toward building the "U.S. Deorbit Vehicle," a customized spaceship designed to ensure the ISS's safe and regulated fall into Earth's atmosphere.

A New Era in Space Station Management
When it was first launched in 1998, the International Space Station was meant to be a place where scientists could work together and study. The station is almost done being used, so plans for deorbiting and safe destruction have become very important. NASA's choice of SpaceX shows how private companies are becoming more involved in space projects that the government once ran.
NASA first asked U.S. aerospace companies for ideas in March and September 2023. They were looking for a "space tug" ship that could safely remove the U.S. section of the ISS from orbit. On June 26, 2024, NASA announced that SpaceX had won the contract to design and deliver the United States Deorbit Vehicle.
This vehicle will be separate from SpaceX's Dragon capsule, which now transports supplies and crew to the station. Instead, it will be specifically built to aid the ISS's controlled descent and disintegration during reentry, guaranteeing that it poses no threat to populated areas.
Ken Bowersox, associate administrator for the Space Operations Mission Directorate at NASA Headquarters, emphasized the mission's importance. He stated that selecting a U.S. Deorbit Vehicle for the International Space Station would assist NASA and its international partners in ensuring a safe and responsible transition to low Earth orbit at the end of station operations. He said that this decision supports NASA's ambitions for future commercial destinations while allowing for the continuous usage of space around Earth.

The Reorbiting and Deorbiting Process
Deorbiting the ISS is a complicated job requiring precision engineering and meticulous preparation. The space station and deorbit vehicles will collide as they reenter the atmosphere. One of SpaceX's critical difficulties will be to develop a spacecraft that assures the station reenters in a manner that poses no harm to populated areas on Earth.
Currently, NASA, the Canadian Space Agency (CSA), the European Space Agency (ESA), the Japan Aerospace Exploration Agency (JAXA), and Russia's State Space Corporation Roscosmos work together to keep the ISS operational. Each agency administers and controls the hardware it contributes, while all partners share responsibility for the ISS's safe deorbit. While the United States, Japan, Canada, and the ESA have committed to operating the ISS until 2030, Russia has pledged to support its operations until 2028.
NASA had explored using a Russian Roscosmos Progress spacecraft for the deorbit mission but ultimately decided that a new, dedicated spacecraft was required. The launch contract for the U.S. Deorbit Vehicle will be released separately, implying that this development phase is only the beginning of a more significant effort to responsibly manage the ISS's end-of-life stage.
Planning for the Future of Space Exploration
SpaceX's selection for this vital mission illustrates NASA's overall objective of supporting private space firms while continuing its scientific and exploratory missions. Bowersox said that the orbital laboratory continues to be a model for science, exploration, and teamwork in space for everyone's benefit. He discussed the history of the International Space Station and its contributions to several research sectors, including Earth and space science, biology, human physiology, and technology demonstration.
As the ISS's helpful life ends, many commercial space stations are being built to carry on the tradition of study and innovation in space. Companies such as Axiom Space, Blue Origin, and Voyager Space are creating stations that will eventually replace the ISS in maintaining people and conducting scientific research in low Earth orbit.
NASA's contract with SpaceX to create the U.S. Deorbit Vehicle is a significant step toward appropriately managing the ISS's end-of-life phase. This mission will secure the ISS's safe disposal and prepare the way for the next generation of commercial space stations, allowing humanity to continue exploring and discovering space.
