Space Sustainability from an African Perspective

Space—it feels limitless. But the misconception that there’s endless room for humanity’s activities in orbit poses a serious threat to the long-term sustainability of outer space. While human ingenuity has always led us beyond the skies, accessing space freely for centuries, the rapid increase in satellite congestion and the mounting problem of space debris have changed the equation. For Africa, where space ambitions are on the rise and more countries are establishing national space programs, tackling these challenges is crucial to ensuring the sustainability and safety of space activities for the continent and the world.

Globally, forecasts project the launch of 28,700 satellites over the next decade, alongside the alarming presence of 130 million pieces of space debris, only a fraction of which can be tracked. African nations must not only prepare to navigate this reality but also actively participate in shaping the solutions. SSA and IOS are essential for safe and efficient operations, particularly as Africa seeks to expand its satellite constellations for Earth observation, communications, and navigation to address developmental needs.


The global private sector, including emerging African companies and startups, plays a pivotal role in tackling these challenges. Businesses worldwide are leveraging advanced technologies—like AI, machine learning, and sensors—to monitor and manage space traffic. As Africa’s space ambitions grow, adopting and tailoring these technologies to local needs offers significant opportunities for capacity building, knowledge transfer, and economic growth. These services—ranging from collision avoidance to satellite end-of-life disposal—enhance safety and sustainability in space while opening pathways for private-sector growth in the African space ecosystem.

Governance frameworks are indispensable in guiding SSA and IOS implementation. As African nations adopt space policies and legal frameworks, the focus should be on ensuring safety, sustainability, and inclusivity in space operations. Regional collaboration, such as through the African Union and the upcoming African Space Agency, is vital for creating harmonised standards and practices. Clear policies that align with international norms will encourage private-sector innovation while addressing critical concerns like data sovereignty and security.

International bodies like the United Nations Office for Outer Space Affairs (UNOOSA) and European Space Agency - ESA champion collaboration and shared responsibility for space sustainability. Africa’s active participation in these initiatives is crucial for leveraging global expertise and amplifying its voice. Establishing regional SSA centres and forging partnerships with international organisations will strengthen Africa's ability to monitor space objects, ensuring a vital role in managing global space traffic.

Technological advancements, such as space-based sensors, ground-based radars, and optical telescopes, offer the foundation for SSA and IOS solutions. Investments in these technologies by African nations and regional bodies will improve their ability to track satellites and space debris. Proactive measures like autonomous collision avoidance algorithms and satellite servicing technologies can transform how African countries manage space assets, boosting the continent's global competitiveness.

A critical decision for African governments will be whether to rely on commercial SSA and IOS providers or develop their systems. Outsourcing can offer access to cutting-edge technology without heavy infrastructure investments, but it raises concerns about data sovereignty and reliance on external entities. Alternatively, building local capacity and infrastructure for SSA ensures autonomy and aligns with long-term goals for self-reliance, albeit at a higher initial cost.

By 2035, the global SSA and IOS landscape will likely see real-time tracking, predictive analytics, and autonomous operations become the norm. For Africa, this evolution represents an opportunity to forge strategic alliances, invest in local talent, and build capacity to address these emerging challenges. Collaboration across the continent and with international stakeholders will be crucial in ensuring that African nations contribute to and benefit from a sustainable and secure space environment.

In conclusion, Africa stands at the threshold of a transformative era in space exploration and sustainability. By embracing cutting-edge technologies, fostering collaboration across the continent and beyond, and championing forward-looking governance frameworks, Africa can secure its place as a key player in ensuring the safety and sustainability of space activities. These efforts will safeguard not just its growing space ambitions but also the shared future of humanity’s exploration and utilisation of space.
