Could Humans Live On Mars?

“Could humans live on Mars?” is a question that needs to be answered because a lot of earthlings seem to believe humans could live on Mars, and may have to sometime soon. They believe that earth will become uninhabitable, and soon not just in thousands of years. Mars is presently quite uninhabitable to humans or any other form of life from the animal kingdom. I suppose they believe that they can transform Mars to a human/animal friendly place within the short time they predict earth will become uninhabitable.

I think the people who make this sort of claim, mostly millennials, are nuts. However, I do agree that earth is going to become uninhabitable sometime in the future.  It’s just that it will be several hundred million years from now when that occurs.

It seems possible, even likely, that earth will someday no longer be able to sustain the sort of life that abounds on it today. That’s because for most of earth’s 4.5 billion years of existence it has been hostile to most life forms, especially humans.

Some form of animal life has existed on earth for at least 650 million years, since the Cambrian explosion. There was even very primitive single-cell life for a few hundred million years before that. For most of the time since the Cambrian explosion there was insufficient oxygen in earth’s atmosphere for humans or animals that breathe through lungs to live here. Animals with gills that spent most their time under water lived on earth for quite while before the rise of those who could live out of the water.

This means, contrary to the millennial mindset, that humans will not be colonizing Mars any time during the next few hundreds of millions of years. There just won’t be any need to.

Nevertheless, could we do it in say another hundred years,  if we wanted to? NASA chief scientist Jim Green says absolutely, we can and the first person to go probably is already alive and living on earth.

Green then goes on to list what living on Mars will be like.  First of all, we’ll need to wear a space suit all the time, 24/7 and 365. A human on Mars will do everything he or she does from the inside of a space suit. You see, there is no oxygen on Mars. Outside the space suit you’ll be dead in 4 minutes or less. What will it be like to sleep, work, eat, go to the bathroom, talk, read, walk, run, work out on the stair master, have sex, and build houses without taking the space suit off? What will the new Martians do when all the oxygen bottles run empty?

A few of other things to overcome: It’s darn cold on Mars. Average temp is below zero and can fluctuate 170 degrees from one day to the next. Mars’ gravity is 38% of earth’s so you need a real heavy space ship to land. At least 10 tons (on earth) according to Jim Green.

That heavy space ship will be harder to launch from earth and use more fuel. It about a 9-month journey to get to Mars. Not only is getting back also 9 months, you can’t go from earth to Mars or vice versa any time you might want. You have to wait until the solar system’s planets and other space objects are lined up just right so that you have a proper navigational path to follow. You don’t want to have a crash with a comet or meteorite on the way. That could add months to the trip each way.

Mars does have an atmosphere but it’s 99% carbon dioxide. What are millennials thinking? They hate CO2 and believe it’s some sort of evil potion even though without it there would be no trees, no plants of any kind, no cornfields, no wheat nor barley nor hops and so no beer. No beer? Millennials say they want to go to Mars, do they know there won’t be any beer? Well, except what you make on earth and take with you. Even then, how do you drink beer with an air-sealed space suit on?

I don’t think mother earth is going to make herself hostile to human life. I think it will come, if it does, from the continued spread of stupidity and ignorance that now has a grip on just about every sector of human society now living on the good earth.
