The Indian Space Research Organisation (ISRO) has formalized an ambitious national mission blueprint titled ‘Swachh Space’, establishing a mandatory operational framework to achieve ‘Debris Free Space Missions’ (DFSM) and systematically de-orbit India’s space debris footprint across Low Earth Orbit (LEO) by 2030.
According to official orbital tracking metrics released by the Department of Space, India currently has 129 trackable defunct objects and spent rocket stages circulating in Earth orbit. The Swachh Space initiative mandates active passivation, controlled atmospheric re-entry mechanisms, and robotic grappling tech on all future PSLV, LVM3, and Next-Generation Launch Vehicle (NGLV) missions.

01. India’s Orbital Footprint: Current Space Debris Breakdown
| Orbital Debris Category | Object Count (Tracked) | Operational Status & Altitude Zone |
|---|---|---|
| Active Indian Satellites | 54 Satellites | Operational in LEO, GEO, and GTO orbits |
| Defunct / Retired Satellites | 48 Objects | Parked in graveyard orbits or decaying LEO trajectories |
| Spent Upper Rocket Stages | 81 Stages (PSLV / GSLV / SSLV) | Subject to mandatory end-of-life passivation protocols |
| Total Trackable Indian Space Debris | 129 Objects | Monitored continuously via IS4OM network |
| Global Debris Share | Less than 0.6% | One of the lowest orbital pollution footprints among spacefaring nations |
02. Core Technological Pillars of ‘Swachh Space’ by 2030
To ensure that zero orbital remnants are left behind after launch cycles, ISRO has integrated five core engineering mandates across its launch vehicle and satellite manufacturing lines:
- Controlled Atmospheric De-Orbiting: Lower stages and spent PSLV 4th stages (PS4) will carry reserved propellant margins to initiate retro-firing burns within hours of payload separation, driving the hardware into non-populated oceanic splashdown corridors.
- Passivation Systems: Mandatory venting of residual fuel, oxidizers, and battery electrical discharge protocols at mission completion to eliminate spontaneous orbital explosions caused by thermal cycling.
- IS4OM Command Surveillance: Upgraded radar, optical telescopes, and collision avoidance algorithms at the ISRO System for Safe and Sustainable Space Operations Management (IS4OM) facility in Bengaluru.
- Design for Demise (D4D): Transitioning satellite chassis components from heavy titanium and refractory alloys to aerothermally combustible materials that burn up entirely during atmospheric re-entry.
03. Global Space Sustainability & UN Guidelines
The Swachh Space declaration positions India ahead of the United Nations Committee on the Peaceful Uses of Outer Space (UN COPUOS) guidelines, which currently target voluntary 25-year de-orbit guidelines. ISRO’s commitment tightens compliance down to an active 5-year post-mission disposal threshold for Low Earth Orbit operators.
04. Frequently Asked Questions (FAQ)
What is ISRO’s ‘Swachh Space’ initiative?
‘Swachh Space’ is India’s national mission framework aimed at eliminating orbital debris from Indian space missions and achieving Debris-Free Space Missions (DFSM) by 2030.
How many pieces of space debris does India currently have in orbit?
According to government disclosures, India has 129 trackable debris objects in orbit, which accounts for less than 0.6% of all global space junk.
How will ISRO clean up spent rocket stages?
ISRO utilizes controlled de-orbiting burns via reserved propellant, passivation of batteries and fuel tanks, and designed-for-demise structural materials that burn up upon atmospheric re-entry.
