The idea of manned space explorations is nothing but a blatant attempt to woo votes from the government employees and government contractor employees in the aerospace industry. It’s a complete waste of money. There is no conceivable material on the moon or any other exotic location in the solar system that is worth the cost of getting it.
Well, I heard the universe is really flat and when you go over the edge, you fall into a black hole!;-)
And if that weren't bad enough, there's no cell phone service in a black hole.
If it's here on Earth, it's found throughout the cosmos.
What's the asteroids, moon and Mars made of? Pixie dust?
Subtly Shaded Map of Moon Reveals Titanium Treasure Troves
Ever hear of a Nickle-Iron Asteroid? Carbon Asteroids? Water on the Moon? Water on Mars?
The Moon is full of silica's for glass, Iron and far more that have built up from billions of years of bombardments.
The notion that none of these elements exists in space is ludicrous.
It's thought that some of the richest iron and copper deposits on Earth were put here for our use by asteroid impacts.
Just a thought.
