It is unwise to engage Flat Earthers or other science deniers because their denial is due to ideology rather than facts. You could tell them that the Moon looks upside down in Australia and then ask them to explain that, but then disengage because they will simply throw word bombs at you to show...

We've been doing that for millennia - expanding oases, damming parts of the sea, etc. And with Climate Change, Antarctica is well on its way to being much more habitable. (Sorry, penguins.)

Other rocky planets and moons in our solar system cannot be terraformed because their gravity is wrong and because they lack a magnetosphere.

The past predicts the future. Humans do not and have never lived for any length of time in places that kill people quickly. We do not live outside of oasis area in deserts. We do not live on mountains above 12,00 feet. We do not live in Antarctica and won't until it warms up some more. And we...

I think better Earth analogies to Mars colonization would be mountains over 20,000 feet - nobody living there! These places have many similarities to Mars - lots more radiation, lots less air, and very cold.

It's best to not engage Flat Earthers, anti-evolutionists, etc. They believe what they believe and are impervious to reason, supporting data, or anything like that. It's futile to try. Your time and efforts are better spent elsewhere.

I really don't think the Americas are a good template for Mars. There's just no comparison. Europeans didn't colonize the Americas. They conquered the humans who had already colonized the Americas thousands of years earlier. The Europeans were just moving in to a section of Earth that they...

Even a very bad climate change/global warming devastated day, a day on Earth is far more survivable than a day on Mars. Always has been. Always will be. So the excuse that Mars is Plan B if Earth fails is not tenable. Earth will not fail. It'll give us a whupping from time to time to keep us in...

NASA has developed a one-stop-shop for educational materials for home schooling and also for anyone else. Just type NASA STEM into your browser and take off (as it were) from there!

Well, when I talk to scientists and engineers who study and operate on Mars as well as those who study the health of ISS astronauts, I am definitely hearing about major health concerns. We must be talking to different sets of scientists. I really do not have time to cite studies, because they...

LOL You have no idea who you are talking to with those ridiculous and insulting remarks. Personal attacks always indicate a weak argument.

Mental Avenger: Please learn more about Mars. It is not like when Europeans colonized the Americas. The American continent had people living on it so that they as well as the newcomers could enjoy the basics of normal gravity, plenty of water, food from plants and animals, and plenty of air to...

I envision Mars as eventually becoming something like Antarctica - a place of multinational exploration and scientific study with adult humans cycling in and out of research stations. I'm less sure about tourism due to the length of the round trip. Mining can be done robotically. I think it...

Why go to Mars to live in a cave? You can do that on Earth!

In this article, "bacteria hitching a ride into the galaxy aboard a comet" is included in a list of weird concepts that turned out to be true. Since when is a hypothesis the same thing as a true fact??
