It's not a proposal. It's a literature survey. A very good
one and one people here should read thoroughly.

Very few people do real things in space. NASA is one of them.
I wouldn't diss NASA. It certaintly took harsh budget cuts
to make them attempt serious projects in areas of robotics
and in-situ resource utilization, but they're at least on
the right path.

You keep blowing my mind with these off-hand remarks of yours.

If you don't like NASA, just wait another decade or two.
The budget gutting will continue until morale improves
(or the patient expires). And the first guys in control
of the Moon own the entire solar system.

Semi-soft landing of >100 kg parcels on Luna affordably is the
most expensive and critical aspect of the venture. Scaling down
robotics and moving towards self-replication closure is a much
easier problem in comparison. One you could attempt at leasure
in groundside labs, and lunar simulators. If people do it right
it will be competitive, multi-team, and prize-based.

A journey of a megameter begins with a single step.
