When I first saw images from NASA’s various Mars rovers, I was almost crawling out of my skin with excitement. As I spoke at a NASA sponsored conference where scientists and engineers were discussing plans for a Mars mission and colonization, I was enthralled with the thought that humans are actually planning for mankind to leave our planet for a foreign world.
Lately, I’ve been thinking about what I would miss if I were a colonist on Mars. I’ve decided, what I would miss the most is something we take for granted in most places of the world; water.
Of course, Martian pioneers would have to have abundant stockpiles of drinking water. But I sure would miss Earth’s oceans; their awe inspiring breadth and depth, their multitudes of sea life, and the gentle shades of blue-green in clear water along sandy coasts. 
I would miss the sound of the surf, the laughter of children chasing and being chased by harmless but persistent waves.
I would miss the sound of clicking shrimp, and the clicking of dolphins corralling schools of fish.
I would miss being able to open the windows on a perfect day. I would miss feeling a breeze on my bare face.
I would miss never having to wonder if I had enough oxygen to breathe. I’d miss not worrying that toxic carbon dioxide would seep into my tiny house and suffocate me and my family in our sleep, or that my home’s pressure barrier would fail and our blood would essentially boil, releasing a flood of deadly bubbles stopping our hearts.
I am concerned that those attempting to colonize Mars woud sink into a chronic melancholy simply because the water that pleases and sustains so many of us is absent on Mars. Could these homesick astronauts survive, and even thrive?
If the first wave of colonizers did survive, procreate, and nurture the next generation, the first generation of true Martians, then I suspect that generation would fare much better psychologically than the first. After all, they would never have known the verdant forests and splendorous seas of Earth.
As I pondered what it would be like to be a third and fourth generation colonist on Mars, growing up knowing nothing else, I realized that rather than space exploration being a guaranteed and common place activity at that time in the not too distant future, a bleaker possibility exists.
It is entirely possible that war, disease, asteroid and comet collisions, or even the failure of mismanaged banking systems could so impoverish the Earth that space travel to the Martian colony might not remain economically sustainable. Eventually, to the stranded Martians our Earth could be little more than a distant memory, perhaps even a legend. Martian children might grow up on the red planet hearing tales of Sky People who came to Mars from a far away place, a world of indescribable beauty, with colors of blue and green that are not even imaginable on Mars.
Some native Americans have in the past recounted tales of Sky People coming to Earth. Wouldn’t it be ironic if the next generation of Earthlings becomes the fabled Sky People that populate the planet Mars?
If offered the chance to be one of those Sky People on a one-way trip to Mars, would I sign up for the mission? Frankly I don’t think I could leave the most beautiful planet in the solar system, perhaps in the galaxy, even for something as exotic as a trip to Mars.
