Why is this in the news?
The announcement of India’s Debris-Free Space Missions (DFSM) initiative by ISRO Chairman S. Somanath at the 42nd Annual Meet of the Inter-Agency Space Debris Coordination Committee (IADC) in Bengaluru on April 16, 2024, underscores India’s proactive stance on ensuring long-term sustainability of outer space activities. This initiative, targeting zero debris generation by all Indian space actors by 2030, aligns with global efforts to mitigate space debris and reflects India’s commitment to preserving the outer space environment for future generations.
Background
- The proliferation of space debris in Low Earth Orbit (LEO) and Geosynchronous Orbit (GSO) poses significant risks to operational satellites, including those critical for communication, navigation, and Earth observation, thereby threatening the safety and sustainability of space activities.
- The Inter-Agency Space Debris Coordination Committee (IADC), established in 1993, is an international governmental forum for the worldwide coordination of activities related to the issues of man-made and natural debris in space, with 13 member agencies, including ISRO.
- India’s space program has witnessed exponential growth, with over 120 operational satellites in orbit as of 2024, necessitating robust mechanisms to manage space debris and ensure the safety of its assets.
- The 2019 Anti-Satellite (ASAT) test by India, while demonstrating technological capability, highlighted the need for stringent debris mitigation measures to prevent long-term contamination of orbital regimes.
- The United Nations Office for Outer Space Affairs (UNOOSA) has emphasized the importance of the Space Debris Mitigation Guidelines (2007) and the Long-Term Sustainability Guidelines (2018) to ensure the safe and sustainable use of outer space.
- The European Space Agency’s (ESA) Space Debris Office estimates that there are over 36,500 objects larger than 10 cm, 1 million objects between 1 cm and 10 cm, and 130 million objects between 1 mm and 1 cm in orbit, underscoring the urgency of debris mitigation.
What is the Debris-Free Space Missions (DFSM) Initiative?
- The DFSM initiative is a strategic framework announced by ISRO to ensure that all space missions conducted by Indian governmental and non-governmental entities are debris-free by 2030, thereby aligning with global efforts for the long-term sustainability of outer space.
- The initiative mandates adherence to stringent guidelines during the operational life of satellites and launch vehicles, including measures to avoid debris generation, on-orbit collisions, and intentional break-ups, with a focus on reliability and redundancy in mission design.
- Post-Mission Disposal (PMD) is a cornerstone of the DFSM, requiring that spent orbital stages and satellites achieve a success probability of over 99% in controlled re-entry or de-orbiting to orbits with less than 5 years of remaining orbital life.
- The initiative incorporates special considerations for human spaceflight safety, particularly in the 400 km +/- 30 km orbital band, by avoiding minimum orbital transfers and ensuring trackability, identifiability, and maneuverability of all satellites throughout their mission phases.
- Capacity building for space object tracking and monitoring, as well as research on innovative debris mitigation techniques, are integral components of the DFSM, ensuring India’s leadership in sustainable space operations.
- The ISRO System for Safe and Sustainable Space Operations Management (IS4OM) will serve as the nodal agency for implementing the DFSM, coordinating with other entities under the Department of Space to ensure compliance and progress.
- The DFSM initiative is aligned with the global theme of ‘Join Together for a Safe, Secured and Sustainable Space,’ emphasizing the preservation of the outer space environment as a common heritage for future generations.
- By 2030, all satellite and launch vehicle missions will be planned with critical consideration of system health, safety, and readiness for post-mission disposal, ensuring that mission extensions do not compromise orbital sustainability.
