India’s New Rules for Spacecraft Re-entry

1 · Context

As India’s private space sector booms, more satellites are being launched into space than ever before. But what happens when an old satellite dies? If left in orbit, it becomes dangerous space junk. To prevent this, companies intentionally bring them crashing back to Earth (called “planned re-entry”).
However, bringing a massive metal object down through the atmosphere is incredibly risky. If its path is slightly off, it could crash into an airplane, a ship, or even a populated city. To ensure public safety, India’s space regulator, IN-SPACe, has released strict new rules. These guidelines legally force private space companies to mathematically prove their re-entries are safe and to buy massive insurance, protecting both Indian citizens and the government from any potential disasters.

2 · The Re-entry Challenge

Step 1: Space Debris Threat
Low-Earth Orbit is getting dangerously crowded. Old, dead satellites must be safely removed to avoid creating permanent, hazardous space junk.
▼
Step 2: Planned Re-entry
Companies deliberately steer these old satellites back into the Earth’s atmosphere, aiming for them to burn up over empty oceans.
▼
Step 3: The Danger Zone
If the calculation is wrong, large chunks of metal (like batteries) survive the heat and can crash into cities or airplanes.
▼
Step 4: IN-SPACe Regulation
The new rules force companies to mathematically prove the risk to humans is less than 1 in 10,000, and they must buy heavy insurance before trying.

3 · Key Regulatory Concepts

Acceptable Risk Threshold
The 1-in-10,000 Rule
Operators must provide hard mathematical proof that the chance of their falling satellite hitting any person on the ground is strictly less than 1 in 10,000.
Natural Orbital Decay
The Free Pass
Satellites that naturally slow down, fall, and completely burn up on their own (without active steering) do not need special permission under these new rules.
Foreign Entities
Local Responsibility
Foreign companies wanting to crash satellites over Indian territory cannot act alone. They must partner with an Indian company, which takes the legal blame if things go wrong.
Indemnifying the State
Protecting Taxpayers
Private operators must buy massive third-party insurance. If a disaster happens, the private company pays the victims, completely protecting the Indian government from lawsuits.

Prelims Quick Facts: International Treaties
Space Liability Convention, 1972 A global treaty stating that a “launching nation” is absolutely liable for any damage its space object causes to people on Earth or to airplanes in flight.
Outer Space Treaty (OST), 1967 Article IX of this foundational treaty forces nations to avoid harmful contamination of outer space and celestial bodies.
Advance Warnings (NOTAMs) IN-SPACe forces companies to broadcast danger warnings to pilots and ships at least 45 days before they drop a satellite.
Sovereign Clearance If an Indian company plans to crash a satellite near another country’s territory or waters (EEZ), they must get explicit legal permission from that foreign nation.

MCQ Practice Question
Q. With reference to the IN-SPACe guidelines on the re-entry of space objects and international treaties, consider the following statements:

  1. All satellites undergoing natural orbital decay, even those expected to burn up completely without active steering, require mandatory prior authorization from IN-SPACe.
  2. Under the Space Liability Convention of 1972, the launching state is held absolutely liable to pay compensation for damage caused by its space object on the surface of the Earth.
  3. The new guidelines mandate that private operators must secure third-party liability insurance to indemnify the Government of India against potential damages.

Which of the statements given above is/are correct?
(a) 1 and 2 only    (b) 2 and 3 only    (c) 1 and 3 only    (d) 1, 2 and 3

Answer: (b) 2 and 3 only

  • Statement 1 — Incorrect (the trap): The guidelines explicitly exempt spacecraft that undergo natural orbital decay and burn up completely without active trajectory control. They do not need separate authorization.
  • Statement 2 — Correct: The 1972 Convention imposes absolute liability on the launching state for ground and airspace damages.
  • Statement 3 — Correct: To protect taxpayer money, IN-SPACe makes it mandatory for private companies to buy comprehensive insurance, shifting the financial risk away from the government.
