| Helium luckily is the second most abundant element in the universe. A good reason to go to the stars. |

| mostly out of our reach unless you have way of removing it from the sun without your retrieval craft melting or being captured by the suns gravity well or from gas giants without the onboard system being fried by the intense radiation or again captured by the gravitation. |

| We might find it quite difficult to extract from the stars, that said. |

The funny part is, lunar regolite soaks Helium from its exposure to solar wind, so mining it would be an indirect mining of a star, our sun. | |

It would be quite expensive to extract it from there, due to the necessity of escaping from their gravitational field, but not impossible. | | |

| A round-trip lasting centuries is not a practical solution. Star Trek is fiction. |
