My solution is to forget all this silly "Human space exploration" malarkey, and be perfectly satisfied with our time on the Planet Earth, where we, and everything else, was designed to exist in suitable conditions!
Any place beyond our breathable atmosphere is both very uncomfortable and highly dangerous!
We were designed to be "down here"...not "out there"!....

A lump of Poo expelled from the International Space Station and floating in space will collide with your Star-Fighter wind-shield at a speed of 17,150 MPH, plus the forward speed of your craft.
At least it will be easy to spot, rather than droplets of Pee.
...and will make an awful smelly* mess on your wind-shield!....

Being a very sensible and practical sort of bloke, I have no time and/or patience for all this Human Space Exploration stuff.....
...I leave all that fairy-tale stuff to Star-Trekers, and Geeks...and wanna-be Suiciders!....
