I agree. We, humanity, need get off this planet, either to the moon or Mars in establishing permanent independent self sustaining footholds
off-planet as the next steps in our development and exploration of the greater universe.
Money is indeed a problem, but, there's also engineering concerns as well.
For a permanent moon base, for instance, what's used for power? Solar will only work half the time for cycles of near 30 days of light and 30 days
of dark. I nuclear power expected for use in the darkness, or something else?
Radioactivity is also a concern.
In LEO (Low Earth Orbit) astronauts and cosmonauts are protected inside the safe bubble of the Earth's Magnetosphere.from most of the high energy
deadly particles zipping around space.
Long term habitation on the Moon, or Mars where magnetic fields are negligible if not nonexistent would thus require ether some technology to produce
an artificial magnetic field locally, as well as likely requiring to be buried beneath the Lunar or Martian surface.
We know there's water on the Moon and Mars, and at each location fuel in the form of H3 on the moon, and rocket propellant from Martian atmosphere
can be harvested for local power production needs, but, do we have the reliable means to do this yet? We run into issues of engineering.
Certainly we need get off Earth with a foot on the moon, and/or Mars.
There are, still, a number of great challenges that need be met, but, so long as we sit and do nothing about them, we go nowhere.
