Elon Musk‘s SpaceX has added another milestone to its impressive resume by securing an $843 million contract to decommission the International Space Station (ISS). The ambitious project will mark the end of an era for the ISS, a collaborative achievement in space exploration since its construction began in 1998.
A Historic Collaboration Nears Its End
The ISS, a joint endeavor between NASA, Roscosmos (Russia), ESA (Europe), JAXA (Japan), and CSA (Canada), has been a cornerstone for cutting-edge research that can only be conducted in the microgravity of space. Orbiting approximately 250 miles (400 kilometers) above Earth, the station has facilitated groundbreaking experiments and technological advancements over its decades-long operation.
Described by NASA as “an unprecedented achievement in global human endeavors,” the ISS has served as a symbol of international cooperation in space. However, its operational lifespan is set to conclude in 2030, after which plans for its safe decommissioning will be set into motion.

SpaceX’s Role in ISS Decommissioning
SpaceX’s contract outlines the use of a specially modified Dragon spacecraft to execute the complex task of deorbiting the ISS. This enhanced version of the Dragon will feature six times the standard propellant and four times the thruster power, making it capable of managing the ISS’s controlled descent.

Once onboard operations cease, NASA plans to gradually lower the station’s orbit over an 18-month period. The deorbit vehicle will then dock with the ISS, using its thrusters to guide it into Earth’s atmosphere.
During its descent, most of the ISS will burn up due to atmospheric friction. However, some larger modules will survive reentry and are expected to land in a designated splash zone. The exact location of this debris field has not yet been disclosed by NASA.
Ken Bowersox, NASA’s Associate Administrator for Space Operations, emphasized the significance of this project:
“Selecting a U.S. Deorbit Vehicle for the International Space Station will help NASA and its international partners ensure a safe and responsible transition in low Earth orbit at the end of station operations. This decision also supports NASA’s plans for future commercial destinations and allows for the continued use of space near Earth.”
Looking Ahead: The Future of Space Exploration
The retirement of the ISS doesn’t signal the end of human presence in space. Plans for nine new space stations, including China’s Tiangong station, aim to continue humanity’s exploration and research endeavors in low Earth orbit and beyond.

Meanwhile, SpaceX continues to solidify its role as a leader in the space industry. In addition to the ISS deorbit project, the company recently secured a $256 million contract for NASA’s Dragonfly mission. This mission, set to launch in 2028 aboard a Falcon Heavy rocket, will send a rotorcraft to Saturn’s largest moon, Titan.
A New Chapter in Space Exploration
As the ISS approaches its final chapter, SpaceX’s involvement underscores the growing role of private companies in shaping the future of space exploration. The decommissioning of the ISS not only reflects a transition in technology but also highlights the potential for collaboration between government agencies and private enterprises to achieve groundbreaking milestones.
From facilitating international cooperation to advancing our understanding of the universe, the ISS has left an indelible mark on human history. Its controlled retirement, spearheaded by SpaceX, will pave the way for the next era of space exploration and innovation.
