With magnetic attraction, a very slow process of deflection might be acceptable, with significant amounts collected over periods of, say, years. The other aspect here is that the magnets may deflect objects large enough to pose a threat, into the atmosphere.

What percentage of the objects in orbit are small enough to burn up safely in the atmosphere? What percentage by mass?

What if we gathered up all the items in orbit around the Earth which are small enough to burn up in the atmosphere, and direct them into the atmosphere? Sizing is an issue. Can be done with a kind of filter. Large sail-like object to collect the objects, with a filter, excluding objects above a...

Do they have an estimate for how long this era would last, the pancake massive star super super supernova (I hope you don’t mind if I call this the PMSSSSN.) era? I have two pictures in my mind related to this: the PMSSSSNing happens in a single rush, or, alternatively, it is spread out over a...

Very interesting. Digesting.

Also, hydrogen, as part of water, is easy to get. Hydrogen on its own, not so easy.

Thinking about this further ... Hydrogen gas at high pressure may work? This may require very high pressures. Working with high pressure gas can be awkward. Hydrogen chilled to a liquid? Oh. that would require chilling to below 20K. Very awkward. None of this is practical. The 40 feet of water...

Lots of really good information here. Thank you!

Reading about material to be tested at the ISS which is designed to provide external protection for structures in orbit or transiting to the Moon or Mars, or on the surfaces of the Moon or Mars. I understand that exposure to particles and radiation is a major threat to the health of the...
