Imagine a rocket launching into space, carrying satellites into orbit. Sounds cool, right? But what happens when parts of that rocket fall back to Earth? Sometimes, they land in unexpected places, like on someone’s house, causing damage and releasing toxic smoke. This is a problem that happens more often than you’d think, especially in some parts of the world like China, where rocket parts have been known to crash into villages and homes.
Space debris, or space junk, is a big issue. Pieces of old satellites, rocket parts, and even tiny bits of paint are constantly falling back to Earth. Most countries try to make sure this debris lands in the ocean, away from people, but it doesn’t always work out that way. For example, in 2015, a piece of a SpaceX rocket ended up washing ashore in the Bahamas. Some vacationers found it and returned it to SpaceX after contacting Elon Musk on Twitter.
Space debris can sometimes be dangerous. In 1978, a Soviet satellite with nuclear material crashed in Canada, spreading radioactive debris over a large area. Cleaning it up was a huge task that took months and cost millions of dollars. Canada even sent a bill to the Soviet Union for the cleanup, marking the only time one country has billed another for space debris cleanup.
So, what happens if space debris lands on your property? According to the Outer Space Treaty of 1967, the original owner of the debris, like SpaceX, still owns it unless they say otherwise. Sometimes, companies want their debris back to study it, but often, they don’t. This means if you find space debris, you might be able to keep it or even sell it!
Predicting where space debris will land is tricky. For instance, parts of a SpaceX Dragon capsule were supposed to burn up in the atmosphere, but a piece ended up on a farm in Australia. Astronomers can only estimate where debris might land, making it hard to avoid populated areas completely.
With more rockets launching and more satellites in orbit, the risk of debris hitting someone is increasing. Scientists estimate there’s a 10% chance someone could be hit by debris in the next decade. In 1997, a woman in Oklahoma was hit by a piece of a Delta 2 rocket, but luckily, it was light and didn’t cause serious harm.
Some people see space debris as a lucky find. When a SpaceX rocket exploded, pieces of it rained down, and some people collected them to sell online. One person even made over $1,000 selling metal scraps!
Space debris is a fascinating yet challenging issue. While it can cause problems, it also offers unique opportunities for those who find it. As space exploration continues to grow, finding ways to manage and reduce space debris will be crucial for keeping our planet safe.

Satellites into orbit. Unfortunately, this was the aftermath. After the rocket’s first stage completed its mission, it fell back to Earth and landed on a house. This not only destroyed the house but also released yellow smoke that filled the air with toxic gas. For China, this is a relatively common occurrence. Many rocket parts have fallen onto villages and crashed into homes due to carelessness.
In reality, space debris is always falling back to Earth. While most of the world tries to keep it away from populated areas, that doesn’t always succeed. In 2015, SpaceX shared impressive GoPro footage from inside one of their fairings as it tumbled back to Earth. At that time, fairings weren’t being recovered. So how did they retrieve this stunning footage? It turns out that after crashing into the ocean, this piece of debris floated all the way to the Bahamas, where it washed up on Elbow Cay. Three businessmen on vacation discovered the debris and identified it as part of a SpaceX rocket. After reaching out to Musk on Twitter, they agreed to return the GoPro and data recorder to SpaceX.
However, space debris can sometimes cause serious problems. In 1978, a 4-ton nuclear-powered Soviet satellite crashed back to Earth, carrying around 50 kg of enriched uranium. This scattered radioactive debris across a large area in Northern Canada. Some pieces had enough radiation to be lethal after only a few hours of contact. To clean up the mess, Canada organized a search team equipped with airplanes and helicopters, launching ‘Operation Morning Light’. The team ventured into the -40 degree tundra to locate and clean up every piece of debris from the satellite. This operation lasted several months and cost a total of 6 million dollars. Canada sent a bill to the Soviets, who eventually only paid half of it. This remains the only case where a country filed a liability claim against another country.
But isn’t space junk supposed to be dropped into the ocean? And who owns the debris if it lands on land? Before we delve into this, a quick mention of Ground News, who made this video possible! Developed by a former NASA engineer, this news platform allows you to compare articles from over 50,000 sources worldwide across the political spectrum, all in one place. Each article breaks down the data and shows the political leanings of the news outlets that reported on the story.
For example, you can see who’s reporting on another Chinese rocket falling back to Earth and which outlets are more factually accurate. You can also observe how headlines differ based on the political background of the source. This helps you see through sensationalism in the news and gain a clearer understanding of global events.

There’s no doubt that space debris is a significant issue. Millions of pieces of space debris surround our Earth, from old satellites to tiny flecks of paint. There’s even some urine up there, as astronauts used to dispose of it outside their spacecraft before it could be recycled into drinking water. When it comes to objects reaching the ground, we primarily need to worry about larger pieces, as smaller ones typically burn up in the atmosphere. For tracking, we use the Space Surveillance Network, which employs telescopes worldwide to catalog space debris. It currently tracks over 27,000 pieces of debris larger than a baseball.
The challenge is that most of these objects cannot be controlled, making it difficult to predict when and where they will reenter the atmosphere. But what if debris lands on your property? Recently, a loud bang was heard over Western Australia, and soon after, a large chunk of metal was found on a man’s farm. This 30 kg object turned out to be a piece of SpaceX’s Dragon capsule. Its size made removal a significant challenge. But who owns it now? SpaceX or the farmer? Thanks to the Outer Space Treaty of 1967, SpaceX retains ownership of this debris unless they explicitly state otherwise.
Sometimes, rocket companies analyze their debris to learn about their spacecraft’s disintegration and reentry. In such cases, it’s up to the country where it landed to collect the debris and return it to its owner. Generally, space companies don’t want their debris back, so whoever finds it can keep it. In this instance, the farmer could potentially make a decent amount of money by selling parts of the debris online. If no one claims it, local authorities will clean it up and bill SpaceX.
But why didn’t this piece land in the ocean? Before the Dragon capsule performs its deorbit burn, the trunk section is discarded and left in orbit until it eventually burns up in the atmosphere. After spending a year in space and completing hundreds of orbits, astronomers couldn’t predict its exact reentry point, only a rough estimate.
What if a piece of debris were to injure someone? The number of rocket launches has reached an all-time high, and the number of satellites in orbit has grown exponentially in recent years. Scientists estimate a 10% chance that someone could be hit by debris in the next decade. This has already occurred. In 1997, a woman in Oklahoma was walking in a park when she saw bright lights in the sky. Half an hour later, she was struck by a piece of metal that had fallen from the sky, which turned out to be from a Delta 2 rocket she had just seen reentering the atmosphere. Fortunately, the piece was thin and light, so its speed was low when it hit her. This was the first and only known case of rocket debris hitting a human.
Interestingly, some space enthusiasts might view debris falling nearby as lucky rather than unlucky. When Starship SN11 exploded in the sky, thousands of debris pieces rained down over Boca Chica. Some parts floated 7 km downrange, where local spectators collected them. Many of these parts appeared on eBay, with one individual making over $1,000 selling metal scraps and heat shield tiles. Although SpaceX likely wanted these pieces back, for that person, it was just a successful day with a metal detector.
