What Happened
- The Indian Space Situational Assessment Report (ISSAR) for 2025 documents 315 successful space launches globally in 2025, with approximately 4,651 objects placed in orbit — reflecting the accelerating pace of space activity driven by commercial constellations.
- The report was prepared by ISRO's IS4OM (System for Safe and Sustainable Space Operations Management), the dedicated division for space traffic management and debris monitoring.
- The sharp rise in launches (315 in 2025 vs. 254 in 2024) is primarily driven by mega-constellation deployments by commercial operators, increasing the risk of collisions and the generation of new debris.
- India committed to achieving Debris-Free Space Missions (DFSM) by 2030, requiring near-complete compliance with Post-Mission Disposal (PMD) requirements for all Indian governmental and private missions.
- Project NETRA — India's dedicated space situational awareness network — continues to expand, with a new space debris monitoring radar established in Chandrapur, Assam, tracking objects as small as 10 cm within a 2,000 km range.

Space Situational Awareness (SSA) — Concept and Strategic Importance
Space Situational Awareness (SSA) refers to a nation's ability to monitor, understand, and predict the physical location of natural and man-made objects in orbit. SSA is foundational to satellite safety, collision avoidance, and the long-term sustainability of space operations. As orbital space becomes increasingly congested, SSA capability is a strategic asset — nations with superior SSA can protect their space assets and potentially deny space use to adversaries.
- Orbital regimes: Low Earth Orbit (LEO) — 160–2,000 km; Medium Earth Orbit (MEO) — 2,000–35,786 km; Geostationary Orbit (GEO) — ~35,786 km; Graveyard/Disposal Orbit — above GEO
- As of end-2024, India had launched 136 spacecraft including 22 operational LEO satellites and 31 GEO satellites
- India's total catalogued debris: 23 defunct satellites in LEO, 26 in GEO, plus rocket bodies from PSLV (40), GSLV (4), and LVM3 (3) missions
- Kessler Syndrome: A theoretical cascade scenario (proposed by NASA scientist Donald Kessler, 1978) where a critical density of debris causes a chain reaction of collisions, rendering certain orbital bands unusable — heightens urgency of debris mitigation
Connection to this news: ISSAR 2025's data on 315 launches and 4,651 objects placed in orbit illustrates the growing congestion that makes India's SSA capability — through IS4OM and Project NETRA — strategically essential.
IS4OM and Project NETRA — India's SSA Architecture
India's space situational awareness is institutionalised through IS4OM (ISRO System for Safe and Sustainable Space Operations Management) and Project NETRA (Network for Space Objects Tracking and Analysis).
- IS4OM: ISRO's dedicated division for space traffic management; compiles ISSAR annually; leads India's Debris-Free Space Mission programme; provides collision avoidance recommendations and re-entry tracking
- Project NETRA: India's SSA network; sanctioned budget: ₹509.01 crore; control centre handles collision avoidance; equipped with the Multi-Object Tracking Radar (MOTR) at Sriharikota, capable of tracking ~10 cm objects
- New radar in Chandrapur, Assam: Tracks objects ≥10 cm within 2,000 km range — significantly enhancing India's independent tracking capability
- India aims for DFSM (Debris-Free Space Missions) by 2030: All Indian missions (governmental and private) to ensure near-complete Post-Mission Disposal (PMD) compliance
- PMD requirements (per UN IADC guidelines): LEO satellites must deorbit within 25 years of end of mission; GEO satellites must move to a graveyard orbit at least 300 km above GEO
Connection to this news: ISSAR 2025 is IS4OM's annual flagship output — and the 315-launch figure underscores why Project NETRA's tracking infrastructure and India's DFSM commitment are not aspirational but operationally necessary.
Global Space Governance — Treaties and Debris Mitigation Frameworks
Space governance is anchored in the 1967 Outer Space Treaty (OST), which establishes that outer space is a "global commons" — not subject to national appropriation. However, the OST predates commercial spaceflight and provides no specific debris mitigation provisions.
- Outer Space Treaty (1967): Foundational space law; 114 states parties including India; establishes state responsibility for national space activities (Article VI) and liability for damage (Article VII)
- Liability Convention (1972): Provides for compensation for damage caused by space objects; India is a signatory
- Registration Convention (1976): Requires states to register space objects with the UN Secretary-General; India is a party
- IADC (Inter-Agency Space Debris Coordination Committee): Founded 1993; 13 member space agencies including ISRO; sets voluntary debris mitigation guidelines (25-year deorbit rule for LEO)
- UN COPUOS (Committee on the Peaceful Uses of Outer Space): Primary UN forum for space law and policy; adopted Long-Term Sustainability (LTS) Guidelines for outer space activities in 2019 — 21 voluntary guidelines
- No binding international treaty on space debris management currently exists — a governance gap increasingly discussed as commercial launches accelerate
Connection to this news: The 315-launch figure in ISSAR 2025 highlights the pressure on existing voluntary governance frameworks. India's proactive DFSM-by-2030 commitment positions it as a responsible space actor, aligned with IADC norms and COPUOS LTS guidelines, even as binding multilateral rules remain absent.
India's Space Sector — InSpace and NewSpace Policy
India's space sector has been significantly restructured since 2020 to enable private sector participation. The Indian National Space Promotion and Authorisation Centre (IN-SPACe) was established in 2020 as the regulator and promoter for private space activities. The Space Activities Bill (pending enactment) will provide statutory backing.
- IN-SPACe: Single-window regulator for private space activities; authorises launches, provides ISRO facility access; established under Department of Space
- NewSpace India Limited (NSIL): ISRO's commercial arm; handles satellite launch and manufacturing contracts; distinct from IN-SPACe (regulatory vs commercial roles)
- India's first private rocket launch: Skyroot Aerospace's Vikram-S (November 18, 2022, Sriharikota) — first Indian private launch vehicle
- Private sector growth means more Indian-origin objects in orbit — making debris tracking and DFSM compliance directly relevant to non-ISRO operators as well
- India's draft space policy (2023) mandates adherence to national and international debris mitigation guidelines for all licensed operators
Connection to this news: As India's private launch sector grows, the debris management framework studied in ISSAR 2025 must extend beyond ISRO missions — making IS4OM's SSA capability and the upcoming Space Activities Act critical governance tools.
