End of Space – Creating a Prison for Humanity
Kurzgesagt – In a Nutshell・6 minutes read
Space travel is in danger due to debris in low Earth orbit, which could trap humanity on Earth for decades. Efforts to clean up space junk using innovative methods like capture and return missions aim to prevent further debris creation and mitigate the existing threat.
Insights
- The accumulation of debris in low Earth orbit from defunct satellites and spent boosters poses a severe threat to space travel, potentially trapping humanity on Earth for decades or even centuries.
- Innovative methods such as capture and return missions using nets, harpoons, sails, electromagnets, and lasers are being developed to clean up space junk and prevent further debris creation, crucial for maintaining the usability of space for satellites and rockets in the future.

Recent questions
How does space debris affect space travel?
Space debris poses a significant danger to space travel by accumulating in low Earth orbit, potentially trapping humanity on Earth for decades or even centuries. Rockets must achieve high speeds to reach orbit, where they can become trapped due to the difficulty of escaping orbit without excess energy. The debris in low Earth orbit, consisting of defunct satellites, spent boosters, and other fragments, moves at speeds up to 30,000 km/h, posing a severe threat to operational satellites. The increasing amount of debris, combined with the potential for collisions triggering a catastrophic chain reaction, could render space around Earth unusable for satellites and rockets within a decade.
What are the dangers of space debris collisions?
Collisions with space debris pose severe dangers to space missions and satellites. The low Earth orbit is filled with defunct satellites, spent boosters, and other debris, with millions of pieces moving at speeds up to 30,000 km/h. The potential for collisions triggering a catastrophic chain reaction could render space around Earth unusable for satellites and rockets within a decade. These collisions not only threaten the functionality of operational satellites but also pose risks to future space missions and the safety of astronauts.
How can space debris be cleaned up?
Efforts to clean up space debris include innovative methods like capture and return missions using nets, harpoons, sails, electromagnets, and lasers. These methods aim to prevent further debris creation and mitigate the existing threat posed by the accumulation of debris in low Earth orbit. By actively removing debris from space, these cleanup missions seek to ensure the safety and functionality of operational satellites and future space missions.
Why is excess energy needed to escape orbit?
Rockets must achieve high speeds to reach orbit, where they can become trapped due to the difficulty of escaping orbit without excess energy. The accumulation of debris in low Earth orbit poses a significant danger to space travel, potentially trapping humanity on Earth for decades or even centuries. Without the necessary excess energy to escape orbit, rockets risk being trapped in orbit, unable to continue their missions or return to Earth safely.
What is the potential impact of space debris on future space exploration?
The increasing amount of debris in orbit, combined with the potential for collisions triggering a catastrophic chain reaction, could render space around Earth unusable for satellites and rockets within a decade. This poses a significant threat to future space exploration, as the functionality of operational satellites and the safety of space missions are at risk. Efforts to clean up space debris are crucial in ensuring the sustainability and safety of future space exploration endeavors.
