## What do you learn in Space Debris Mitigation

Space Debris Mitigation covers the growing problem of space junk and how to deal with it. You'll learn about orbital mechanics, debris tracking systems, and collision avoidance strategies. The course dives into removal techniques like lasers, nets, and harpoons, as well as prevention methods for future missions. You'll also explore policy and legal aspects of space debris management.

## Is Space Debris Mitigation hard?

It's not a walk in the park, but it's not rocket science... oh wait, it kinda is. The orbital mechanics can be tricky, and there's a lot of physics involved. But if you've got a decent grasp of basic physics and some math skills, you'll manage. The policy stuff is more straightforward, so it balances out the technical challenges.

## Space Debris Mitigation FAQs

1. How much space debris is currently in orbit? There are hundreds of thousands of debris objects larger than 1 cm in Earth orbit. The number of smaller particles is estimated to be in the millions.

2. Can space debris fall back to Earth? Yes, some debris in lower orbits can re-enter Earth's atmosphere. Most small objects burn up, but larger ones can potentially reach the ground.

3. Are there any international laws governing space debris? There are guidelines, like the UN Space Debris Mitigation Guidelines, but no binding international laws yet. Many countries and organizations follow voluntary best practices.

4. How long does space debris stay in orbit? It depends on the altitude. Debris in low Earth orbit might decay within a few years, while objects in higher orbits can stay up for centuries or even indefinitely.
