Hello, i saw a reward posted for the solution of the problem of space trash by Nasa. There are thousands of small objects in space that are discarded rocket parts, pieces of satelittes and general junk up there. It is orbiting the earth at high speeds and Nasa cant solve this problem (yet) i read that they have had some ideas that were either too much of a long shot or just not doable in praksis such as heating the object with lasers from the ground til they evaporate etc. I have a few ideas that may or may not be stupid, i do not know the answer because i dont know what technologies Nasa has available. These ideas may be garbage if they dont have the tech, or if it would be too costly, so please come with ideas of your own. After all.... if we solve this it would be awsome for the forum, and whoevers idea they think is worth the effort. Idea 1: Small maintenance robots. If we could build small robots (size of a football) and remote control them from earth we could launch maintenance satelittes that control their assigned area for scrap objects. They would run on electricity and a propellant of choice and be able to refuel and reload at the sattelite. this would be the permanent solution. with tech advancement it would be made automatic and run by computers. BUT.. it would probably be outside any one space agency's budget so international co-operation would be needed. maybe divide up the sky in sectors and divide the responsibility around. Idea 2: Small rockets. this would be a temporary solution. i do not have the tech knowledge at all to think if this could work but it seems like a possible scenario. Picture a piece of material that is hard and light, it has the shape and size of a card. This would be the front of the missile. Aero dynamics dont aply to space so it should have no influence over the amount of fuel needed to reach the same speeds as the object its tracking. The missile is small, the tip hard. how many would fit on a run of the mill launch? The thing about this scenario is that the missiles are so small that it would not require its own launch rocket. they could take as many as they could fit on the missions already going to space. ps. i didnt know where to put this thread. There are so many to choose from, physics, theory, math, astrology and space dynamics etc. so please dont delete if i posted it in the wrong forum.
