01 · WHAT CHANGED
It has already started
What most people think
Space junk is a problem for later. Stop launching and the sky slowly clears itself.
What the data shows
Even at zero new launches, the total still climbs. Thin air up there drags fragments down, but break-ups add them faster than it can.
ESA, the agency that counts what is in orbit, wrote this in its 2025 report.
Zero new launches, and the debris total still rises.

02 · THE RECORD
Six break-ups wrote today's orbit
Even with nothing new going up, the debris count still rises. Here is where most of it came from.
- Jan 11 2007
Fengyun-1C · China's test. A missile destroyed a dead weather satellite at 865 km.
- Feb 10 2009
Two satellites collide. The first time two whole satellites ever hit each other.
- Mar 27 2019
Mission Shakti · India's test. Fired deliberately low, at 283 km. About 125 fragments.
- Nov 15 2021
Cosmos 1408 · Russia's test. The crew on the space station sheltered in their capsules.
- Jun 26 2024
An old satellite breaks up. A 6-tonne dead satellite came apart on its own. 180+ pieces.
- Aug 6 2024
A rocket stage fragments. It had just released a batch of new satellites. About a tenth of 2025's near-miss risk came from this.
Six break-ups. Three were deliberate tests, one a collision, two just came apart.

03 · THE GROUND RULES
Three words, said plainly
Six dates, one piece of physics under all of them. Three words carry the rest.
Kessler syndrome. One crash makes debris, which means the next crash gets likelier. Two scientists at NASA modelled it in 1978.
Collision avoidance. The satellite fires its thrusters and moves. Fuel burned dodging is fuel it cannot use working.
Decay. Thin air up there drags a fragment down until it burns. Go higher and there is almost no air left.
04 · WHERE IT BROKE
Altitude decides how long the junk stays
Why did one test's cloud vanish while another's is still up there? The answer is the height it happened at.
Five break-ups by altitude. The lowest cleared in two years. The highest clears after 2100.

05 · THE ANNUAL COUNT
The agency's own word for it: runaway
Space-agency prose is usually careful. Here is the 2025 report saying it plainly, and not in the future tense.
Even without any additional launches, the number of space debris would keep growing, because fragmentation events add new debris objects faster than debris can naturally re-enter the atmosphere, and active debris removal is required to prevent the runaway chain reaction known as Kessler syndrome.
In plain words: stop every launch tomorrow and the count still goes up, because things break apart faster than the air pulls them down. What comes next is the bill.

06 · THE RENT
Dodging is now a full-time job
That chain has a price, and it is already being paid. Start with one company's share of it.
Starlink made more than 300,000 avoidance moves in 2025. That is more than thirty course changes every hour, all year long.

07 · SIX READINGS
What sharing the orbit costs now
Three lakh dodges is one company's bill. Here is what the rest of the sky already costs.
Starlink satellites in orbit: 10,074. As of March 20, 2026. Crossed 10,000 on March 17.
pieces of debris ever removed: 0. One mission flew within 15 metres in 2024, then left.
of all near-miss risk in 2025: ~10 %. A near miss is a dangerously close pass. All from one rocket-stage break-up, August 2024.
space-station debris dodges since 1998: 39. The last was April 30, 2025, dodging a 2005 fragment.
objects newly tracked in 2024: 7,473. Break-ups are part of it.
largest fine for leaving a satellite: $150,000. One operator, one satellite, 2023. The only case so far.
Sharing low orbit · 1998 to 2026
08 · THE SHARED BILL
You pay to dodge. Nobody pays to leave.
Everyone up there pays to dodge the junk, because every dodge burns fuel. Nothing has ever been removed from orbit, and only one operator has ever been fined. Both sides here are true at once.
