In its Indian Space Situational Awareness Report (ISSAR) 2025, India’s space agency Isro has shared encouraging news that among the intact Indian upper stages, a total of 36 rocket bodies have re-entered Earth’s atmosphere and burned up safely by 31 December 2025.
Rocket bodies are the large upper parts of launch vehicles that remain in space after placing satellites into orbit. Left unchecked, they can become space debris and pose risks to active satellites and future missions.
Isro’s careful tracking shows the agency is successfully managing this challenge through natural decay and responsible design.
DECAYED ROCKETS
India’s powerful LVM3 rocket, previously known as GSLV Mk III, has seen strong progress in clearing its spent stages.
According to the report, all LVM3 rocket bodies have re-entered and decayed naturally, except three of the rocket bodies from the LVM3-M2/OneWeb India-1 mission, LVM3-M5/CMS-03, and LVM3-M6/BB-1 mission.
These three remain in orbit as of the end of 2025.
This near-complete clearance highlights Isro’s efforts with its heavy-lift vehicle, which is used for important communication and navigation satellites as well as future human spaceflight plans.
STATUS OF GSLV AND SSLV
Amongst GSLV rocket bodies, four from earlier missions, GSLV-F12, GSLV-F14, GSLV-F15, and GSLV-F16, are still in orbit.
The GSLV series has long served as India’s reliable launcher for geostationary satellites that provide weather updates, TV broadcasting, and communication services.
On a positive note, the newer Small Satellite Launch Vehicle (SSLV) has achieved a clean record. No SSLV rocket bodies remained in orbit by the end of 2025.
Designed for quick and affordable launches of smaller payloads, the SSLV appears to benefit from features that help its upper stages re-enter faster and safer.
A CLEAN SPACE
These updates from the 2025 report reflect Isro’s growing focus on sustainable space operations. By ensuring most rocket bodies naturally re-enter and disintegrate harmlessly in the atmosphere, India is reducing long-term risks in crowded orbits.
This means the rockets that power India’s satellites, supporting navigation, disaster alerts, and connectivity, are leaving less clutter behind.
As space activity increases worldwide, such responsible steps by ISRO help keep Earth’s orbital environment safer for everyone. The report underscores India’s commitment to balancing ambitious launches with long-term space cleanliness.
