    The consideration to keep in mind is called space junk, we got quite some trash up there in orbit of our planet. It's considered not to be a problem due that the size of the object would burn in our atmosphere. But what do we need do about the space junk? And is there a possibility that space junk might be dangerous for Earth and its` population?

    I wouldn't say the space junk is a problem for the people down on Earth (at the moment). As when it does fall it get's burnt up in the atmosphere. What is a problem though is that we're polluting it up there to the point that it's getting a little dangerous to launch. We're most definitely getting to a point where we're going to have to start cleaning it up somehow. I've seen projects that include launching a net from a spacecraft that catches junk, then rings it back in to collect it. I think that's a pretty good idea. I know there's a bunch of other projects in the works as well.

    The big number of space junk can damage expensive spacecrafts The growing number of space items can lead to the state where he object density is so high that one collision is enough to generate a cascade effect, leading to further collisions.

    Actually, it's not dangerous for humans on Earth but as I have already mentioned it's rather dangerous for spacecraft and for space companies who's spacecraft can collide and be damaged by space junk and whole mission can be under threat.

    Yeah I can understand that. It's actually really interesting to think about how they know the trajectory of all that stuff floating around up there. They must know where pretty much every piece of junk is at to launch and maneuver safely.

    Space debris is a growing problem. This is a really interesting watch and explains how we could end with space junk ring similar but less cool than Saturn, how the ISS is in trouble from debris collisions and what NASA plans to do about it.

    The growing number of space items can lead to what is known as the ‘Kessler syndrome’, which represents a state where the object density is so high that one collision is enough to generate a cascade effect, leading to further collisions.

    You're so right. Pretty scary.
