Mars Too Small to Be Habitable, New Study Suggests

We Never Know

Well there goes that plan. Time to make another one lol

“Mars’ fate was decided from the beginning,” said senior author Dr. Kun Wang, a researcher in the Department of Earth and Planetary Sciences at Washington University in St. Louis.

“There is likely a threshold on the size requirements of rocky planets to retain enough water to enable habitability and plate tectonics, with mass exceeding that of Mars.”

So, the old standby of 'size doesn't matter' is proven false. Science ftw!

Going to Mars won't help with anything other than practice anyway. There's little of value on Mars in terms of colonization except for scientific purposes. Paradoxically, its gravity well is in between being good as a launching point for further exploration and good for colonization (using Luna as a launching point would be marginally better).

The fact is that there's no Earth 2 within reach anytime soon. We have to take care of the one planet we have. That isn't to say we shouldn't colonize Mars with scientists, because we should. But people hoping for some kind of colonization involving vast cities and other sci-fi wonders are kidding themselves.

I don't think terraforming Mars was ever an option. Underground cities, yes, maybe even domes but no surface dwelling with a real atmosphere.

We can't/don't even populate the harshest places here on earth, which are nothing compared to Mars. So in my opinion its mostly been just a waste of time and money but people have to produce some results if they want to keep getting funding.

Using Luna as a launching point would be way better. Almost no atmosphere, less gravity, nearby, rich in iron, more sunlight, what's not to love about Luna? The only thing that goes for Mars is that there may be more water.

It "suggests" does it? Pretty certain they already have colonies on Mars.

Earth’s gravity is still pretty significant at Luna distances in terms of delta v calculations; it would only be marginally better than Mars

True, but you can obit a payload with a linear accelerator and you have a nice massive body nearby for slingshot manoeuvrers.

This was obvious from the outset.
Mars lost its water & atmosphere long ago.
We can't do anything to change the cause of that.
So its even less habitable than the Moon, which is
closer, & has lower gravity.

Scientists are fragile creatures. I don't see sending them
there as worth the many billions of dollars it would cost.
Probes & remote sensing are more cost effective & productive.

What about Jeff Bezos or Elon Musk. Maybe two day free shipping is the best means.
