Who is responsible for cleaning up space junk?

There is no single entity responsible for cleaning up space junk; rather, it involves collaboration among various stakeholders, including national space agencies, private companies, and international organizations. Countries like the United States and Japan have initiated programs to address space debris, while entities like the European Space Agency (ESA) are actively researching and developing debris removal technologies. Ultimately, the responsibility is shared, and global cooperation is essential for effective solutions to mitigate and manage space debris.
