Summary of the Article: Space Junk and its Impact on Earth
1. Space debris in orbits below 370 miles (600 km) typically fall back to Earth within several years. At altitudes of 500 miles (800 km), orbital decay can take decades. Above 620 miles (1,000 km), debris can continue circling the Earth for a century or more.
2. All space junk is a result of objects launched from Earth, and it remains in orbit until it re-enters the Earth’s atmosphere. Some objects in lower orbits can return quickly.
3. The odds of being hit by space debris are estimated to be around one in 10,000. This is the chance of any person being hit anywhere in the world.
4. The International Space Station (ISS) regularly adjusts its position to avoid space debris. Methods to remove space junk include using space vehicles equipped with tools like nets, harpoons, or robotic arms to capture and de-orbit the junk.
5. Debris below 600 km orbits falls back to Earth within several years, while at altitudes of 800 km, orbital decay can take centuries. Above 1,000 km, orbital debris can continue circling Earth for a thousand years or more.
6. There are currently 100 trillion bits of space junk orbiting the Earth, and the situation is expected to worsen.
7. Technological fixes like nets, harpoons, or lasers can remove space debris, and deorbiting satellites at the end of their lives is a managerial fix. However, these solutions alone won’t solve the debris problem because they do not address the underlying incentives for operators.
8. Experts warn of the potential catastrophe known as the Kessler Syndrome, where the accumulation of debris leads to a cascade of collisions. Urgent action is required to prevent this scenario.
9. In May 2021, a hole was discovered in a robotic arm on the ISS, possibly caused by a rogue piece of space debris.
10. International cooperation is crucial to address the growing issue of space junk and find sustainable solutions for its removal.

How long will space junk take to burn up
Debris left in orbits below 370 miles (600 km) normally fall back to Earth within several years. At altitudes of 500 miles (800 km), the time for orbital decay is often measured in decades. Above 620 miles (1,000 km), orbital debris normally will continue circling Earth for a century or more.
What will happen to all the space junk
All space junk is the result of us launching objects from Earth, and it remains in orbit until it re-enters the atmosphere. Some objects in lower orbits of a few hundred kilometres can return quickly.
What are the odds that one of us will be hit with space junk
There are many different estimates of the chances of space debris hitting someone, but most are in the one-in-10,000 range. This is the chance of any person being hit, anywhere in the world.
How will space junk be removed
The international space station (ISS) has to regularly adjust its position to avoid space debris. One way to get rid of this orbital refuse is to send space vehicles to capture and 'de-orbit' the junk, using tools such as a net, harpoon or robotic arm.
Will space junk ever go away
Debris left in orbits below 600 km normally fall back to Earth within several years. At altitudes of 800 km, the time for orbital decay is often measured in centuries. Above 1,000 km, orbital debris will normally continue circling the Earth for a thousand years or more.

Why don’t we send nuclear waste to the sun
Energetically, it costs less to shoot your payload out of the Solar System (from a positive gravity assist with planets like Jupiter) than it does to shoot your payload into the Sun. And finally, even if we chose to do it, the cost to send our garbage into the Sun is prohibitively expensive at present.
What do astronauts do with garbage in space
Usually, ISS astronauts collect trash and store it on the space station for months waiting for the Cygnus cargo vehicle to arrive at the station. Cygnus is a 'disposable' spacecraft designed to transport supplies to the space station.
