Introduction

The exponential rise in satellites and debris in Earth’s orbit has heightened risks of collisions, threatening the sustainability of space operations and the safety of critical assets.

Challenges of Space Debris Management

  • Growing Congestion in Orbits Mega-constellations and frequent launches have increased the density of objects, especially in Low Earth Orbit (LEO).
  • Kessler Syndrome Risk Collisions can trigger cascading debris generation, rendering orbits unusable.
  • Tracking and Monitoring Limitations Smaller debris (<10 cm) are difficult to detect but can cause significant damage.
  • Lack of Binding Global Regulations Existing guidelines (UN, IADC) are largely voluntary, limiting enforcement.
  • End-of-Life Management Issues Inadequate compliance with deorbiting norms and disposal practices.

India’s Efforts in Space Debris Management

  • Space Situational Awareness (SSA) Establishment of ISRO’s NETRA project to track space objects and predict collisions.
  • Debris Mitigation Guidelines Adoption of international best practices such as post-mission disposal and passivation of satellites.
  • Responsible ASAT Demonstration Mission Shakti (2019) conducted in low orbit to minimise long-lived debris.
  • International Cooperation Participation in global forums like UNCOPUOS and collaboration on SSA data sharing.

India’s Responsibilities in the Current Context

  • Ensuring Sustainable Launch Practices With increasing commercial launches, India must enforce strict debris mitigation norms.
  • Regulatory Framework Strengthening Empowering IN-SPACe and national policies to ensure compliance by private players.
  • Technological Innovation Investing in active debris removal and advanced tracking systems.
  • Global Leadership Role Advocating for binding international norms and equitable use of orbital resources.

Conclusion

Addressing space debris is essential for the future of space exploration. India must balance its expanding space ambitions with responsible practices and global cooperation to ensure a sustainable outer space environment.
