Space is no longer the vast emptiness of science fiction. It is now a busy highway where new cars appear every day and old ones never disappear, making navigating it harder than ever.

A new report by the Indian Space Research Organisation (ISRO) highlights this growing congestion in space, with a significant rise in the number of space objects and a corresponding increase in collision avoidance manoeuvres (CAMs) required for Indian satellites.

Here’s a quick breakdown of the key takeaways from ISRO’s annual Indian Space Situational Assessment Report (ISSAR) for 2023:

  • More objects, more problems: There was a significant increase in the number of space objects in 2023, with 3,143 new objects added compared to 2,533 in 2022. This growth is attributed to a rise in launches and on-orbit breakups globally.
  • Close calls on the rise: ISRO satellites received over 130,000 close approach alerts in 2023. Of these, 3,033 came critically close (within 1 kilometre), necessitating close monitoring.
  • Taking precautions: ISRO had to perform a record number of collision avoidance manoeuvres (CAMs) in 2023 (23) to safeguard its operational satellites from potential collisions.


With 2023 having seen the most launches and deployments on record, this apparent growth is positive for space exploration. But it also creates a crowded and potentially dangerous environment. And this report serves as a wake-up call.

The report emphasises the importance of responsible behaviour and collaboration among spacefaring nations to address the challenges of space debris and ensure the long-term sustainability of space activities. ISRO, being at the forefront of international efforts to address this challenge, calls for the development of a universally accepted framework for space traffic management to ensure the safety and security of space operations. ISRO also actively participates in discussions with other space agencies, and currently holds the chair of the UN working group on long-term space sustainability.
