Funny thing about humanity, we exist in a small region of space called the Habitat zone, or Goldilocks Zone. We must be close to a heat source such as the Sun, not to close; not to far away.

We need 2 gallons every day, clean air and a stable atmosphere; either natural or artificial around our skin. pH and gases ratios must be near perfect, protein, carbohydrates, fats, vitamins or minerals.

Plus humans need social connections and mental rewards and simulations. Simply humans for all our vast accomplishments on planet Earth are a very vulnerable and almost worthless species. To suggest humanity is anywhere near ready to travel to Mars is just pure fantasy. Sure we could do it; but reality says in today's modern world it takes 8 months to get a roadway pot hole filled.

People forget how long it took to get the international space station up and running. Remember it had Skylab and Mir to iron out most of the bugs. Today 99.999 % of people have less than zero interest in the International Space Station. To suggest people have any interest in sending a walking talking human to Mars is the heights of madness, people just do not care and see no useful reason to do such a thing.

Decades ago some very clever people created a Bioshpere two on planet Earth. This was a very very ambitious project and remarkably successful, but a few nasty people forced adverse publicity to shut it down. This marvelous experiment was never given a chance to succeed and any planned mission to Mars has absolutely no useful outcomes for society.

Thus a mission to Mars would have to be privately funded and that will happen just after automobile companies start giving away free cars. Sure it might be nice to visit Mars up close and personal, however reality says only two human beings have visited the very deepest ocean floor beds, just two people.

Humanity has millions of miles of rain forests and ocean depths to explore in the name science, medicine, technology and biology; why would any rational person think visiting a worthless hunk of cast off space rock would be worth spending Gold on ?

Sure Mars is out there, so is the demoted dwarf-planet; renamed as plutoid's. Pluto was a real planet until it was sacked in a reshuffle of scientific bureaucracy. So yes Mars is there, so is Pluto; yet no one talks about visiting poor little Pluto; yes it is a long long way away. But given today's technology Mars is almost as unreachable as Pluto.
