As long as a station only is considered and not a colony the situation according to Peter Kokh seems to be that the ressource for ISRU have to be carried from several lunar locations to the location of the station.

This is the reason why Peter Kokh in the quoted article is doubting if the poles are that good locations for a lunar station of NASA.

Currently I wouldn't carry any mining products from the Moon to Earth - simply because they are most urgently required to settle at the moon. They are needed there much more urgently than on Earth - beginning with NASA's lunar station.

Do you think different?

I agree that it would not be worth exporting most things back to the Earth but one of the reasons for mining the moon in the first place would be to supply Earth with commodities which would generate wealth and hence lead to further investment in lunar activities.

While it is not worth exporting things like aluminium or iron, uranium, platinum and possibly Helium3 are likely to find a market. Also new markets could open up for lunar products such as crystals grown in lower gravity.

Lunar mining operations are not likely to be set up just to support lunar bases they will also produce revenue from sales back to Earth. Even production of rocket fuel, water and oxygen from ice deposits will have customers from Earth.

Yes, agreed by far - but the current timetable says that first NASA will install a lunar station. And they seem to want to base it on ISRU - which means that there will be small plants at the moon producing for the moon.

So by this timetable - derived from informations - at the moon all starts with "lunar mining first for Moon - Earth later" and "lunar industry first for Moon - Earth later".

The reasons are that it is too expensive to carry it all from Earth there. The way reverse will be expensive too - not that expensive as if from Earth to moon but will it be cheaper than to continue using the earthian ressources? To change that first private travels to the moon have to be enabled for I suppose.

The article "Meet Axel: NASA's 'Marsupial' Rover to Explore Craters
" (ww.space.com/businesstechnology/090213-technovel-axel-rover.html) talks about a particular rover that is kept connected to another larger rover and would go down into a crater by gravity but go out by being pulled.

This concept might be the base to install tethers for cable cabins or equipment to install rails from crater rim to crater rim without consumption of propellants.

More yet - it might be applied in lunar montains and valleys (besides being a safer way to get astronauts in and out there).

It also might be a very good add-on to lunar transrapdis.



What about it?
