How good a material is at scratching another material is measure by the Mohs scale of hardness The Mohs scale of mineral hardness is a qualitative ordinal scale characterizing scratch resistance of v …

The problem with mining is not finding the wanted material, but finding it in concentration high enough to make it worthwhile extracting it. …

Is there another way to stabilize the orbit while keeping sending the cargos without having to shoot an equal mass in the opposite direction? You don't need to shoot an equal mass. Momentum is given …

You can attempt to use the chimney principle, turning the pressure differential at your advantage. Place a convergent pipe near the core, provide an heat source to warm up the hydrogen and let it flo …

Rare earths are so rare because the nucleosynthesis bringing to the production of those elements is not the most likely outcome of the processes. As such those elements in asteroids are not going to b …

In the past, before mining technology was sufficiently developed, it was the only way to source iron. …

How can the merchants mine and transport minerals available on the underside of the floating continents? Dig tunnels Harvest minerals from within the tunnels Once the underside has been reache …

How exactly would one go about mining an asteroid made of antimatter? In short: Laser ablation to blow off parts of the object. …

Mining can disrupt the flow of the underground aquifer, resulting in wells drying up or being polluted/made unfit for human use Mining can leave wastes around, which are not exactly life friendly. … For example it has been found that ancient copper miners polluted the places where they operated and refined the ore with large amounts of arsenic, as a result of the refining operation Mining will use …

collapse in on itself, they have to evacuate to orbit 60 kilometers across is just a big lump of loosely connected material, it is far from being under any form of hydrostatic equilibrium, meaning that mining … If any, they need to worry that fragments produced by mining do not get escape velocity and fly away. …

Top it with the related waste of potential ores and related income, I guess the mining company would resort to other methods than blowing explosives near the surface. …

Mining Asteroids Pro: easier to move large masses due to lower gravity easier to locate interesting resources Cons: heat management in lack of atmosphere difficult to hold position in low gravity … work in space suit Mining planet Pro: heat management in atmosphere work with re-breather possible Cons: move loads in high gravity mining prospect needed Once you have an idea of how much …

Considering the signals that an underground mining activity will produce, we can speculate on how to shield them (and what tech level is needed on the human side to detect them). … I guess for this careful prospection before mining is the only viable solution. …

the cost isn’t much of a problem, since any metals unearthed in mining can be sold to cover the expense. This is simply wrong. Why do you think fracking goes back and forth with being used? …

Have you ever seen what happens when an historically significant building needs to be renovated? You demolish the inside and leave only the outside, so that the appearance of the building isn't chang …
