Hola MaHigh-School - February 2020

We talk a lot about Mars. Mars is within reach and
the focus is very much on the technologies, the long
travel time and the most interesting one: should they
come back or just colonise Mars?
After all, what is there to learn really? We have some
rocks and a good theory of how the moon came into
being.
If we look at the list of activities (here) we can see that
the field is very wide now: China, India, Germany, UK,
South Korea and Japan are all in on it.
The thing that is not clear is: why? If we look at some
of the justifications, it is a bit vague: Like this one:
“Moon Express (MoonEx) is an American privately
held early-stage company formed by a group of
Silicon Valley and space entrepreneurs. [..] long-term
goal of mining the Moon for resources, including
elements that are rare on Earth, including niobium,
yttrium and dysprosium (wiki)”
This sounds a bit vague. How to get the ore back
here? Who will mine it? Robots?
Luna-Glob from Russia is surely advanced (wiki):
