Mining Helium-3 on the Moon and sending it to Earth?

It would be best to mine and process material on the moon to obtain helium-3, but my question is, what if we did an unmanned mission? A small robot 1 meter long, powered by solar energy, that takes ...

Would it be more viable to process moon rocks into Helium-3 on the Moon than doing so on Earth?

Helium-3 is a substance that is very useful for nuclear fusion, which can generate a lot of power. Unfortunately we don't have a lot of it on Earth, but on the Moon it can be processed from basic moon ...

How could the presence of 3He be detected on the lunar surface?

I have been investigating this isotope of helium for a while, which is extremely abundant on the moon (and in general in the entire solar system except on planets with atmosphere). It is believed that ...

Deimos and Phobos minerals

I am searching for Deimos and Phobos mineral maps, which probably are the best candidates to find large amounts of He-3 or other valuable resources to send to Mars colonies in the future. I searched ...

When the moon rock heats up to 600°C, does only Helium comes out?

When lunar rock is heated to 600 °C to extract Helium-3, are gases expelled other than helium? Inductance process would be used in heating the rock.

How can 3He be mined on the moon? [duplicate]

Now I know how it is detected, but what would the mining process be like? given that there is a lot on the moon but not concentrated, so you have to process large amounts of surface to extract a ...

Why exactly would "permanently shadowed polar lunar craters... have substantially higher levels of ³He than sunlit lunar surfaces?"

Researching this answer led to ³He in permanently shadowed lunar polar surfaces published in Icarus. The abstract is tantalizing but terse: Abstract Because of their cryogenic temperatures, analysis ...

Are there proven sufficient $^3\text{He}$ reserves in the inner Solar System to sustain fusion reactors for colonisation?

According to the NASA website Energy from the Moon, that assuming we perfect the helium-3 ($^3\text{He}$) nuclear fusion technology required, that $^3\text{He}$ would generate only a very slight ...
