Motivations for Space Exploration

Great discussion. I've enjoyed reading.

I belive that space exploring is truly a good thing.
However there are so many mysteries still on earth that we haven't solved yet, we don't know everything about the human race.
But i do also belive that finding and maybe colonising planets is important for our survival. In case things go bad here on earth

so, this topic lead me to this article:

"Is Asteroid Mining Possible? Study Says Yes, for $2.6 Billion"

i think its a great idea

and it made me wonder if we might be able to use, on earth, energy acquired by an orbiting solar array

which lead me to this:

"How Japan Plans to Build an Orbital Solar Farm"

thanks for this topic Goken, i had no idea of either of these things
