Few asteroids are worth mining, suggests Harvard study


www.bbc.co.uk said:

A new study might contain some bad news for companies hoping to mine asteroids for their valuable ores.

In the last couple of years, start-ups - including one backed by Sir Richard Branson - have announced plans to extract resources from space rocks.

But calculations by Dr Martin Elvis suggest our cosmic neighbourhood might not be such a treasure trove after all.

The Harvard astrophysicist argues just 10 near-Earth asteroids might be suitable for commercial-scale mining.

Crud. That was a major point in actually sending people and robot-ships out to explore. That they would be pioneering the way for resource gathering.

Here at Intel we make processors on 12 inch wafers. And, the individual processors on the wafers are called die. And, I am employed to check these die. That is why I am the DieChecker.

Outer solar system asteroids are another matter and centuries if not further in the future, and they will be mined for water.

We can't let spacecraft re-enter the atmosphere with fuel still in them and we are going to be able to bring fuel chemicals through re-entry?????

Slight difference between uncontrolled crash and controlled landing.

I was thinking the Moon would be the best place to start extraterrestrial resource gathering but as luck would have it some environmental groups are already against it, saying due to the moons gravity  any mining would cause vast amounts of dust to float up and not settle back down to the ground polluting the moon and rendering it visually unpleasing from the Earth.
