... imagine Space Prospectors mining the Asteroid Belt, Space Guard units corralling comets and retrograding their orbits to crash into Mars, adding precious water to the planet's atmosphere, terraforming it into a vibrant colony of mankind.
The moons of Saturn covered with ice, possibly with liquid water beneath, and life waiting for us to find it. Who knows what medical cures live within that life. There is a celestial jungle out there with wonders we can only feebly imagine.
Truly! I do envision miners shooting a stream of heavy metals towards Earth for harvesting; Helium-3 on the Moon’s surface. But, ultimately, it will come from intrepid explorers willing to take the risk. It’s in our DNA. MAN, wouldn’t it be great?
