Yes, let's go to a planet with no magnetosphere. Brilliant idea.

We don't need to terraform. In fact it's a far fetched idea.

We can however live underground. Protected from radiation.

We can then do this on the rocky moons of Jupiter, Saturn, Uranus, Neptune. Then on Pluto.

And if you must live on the surface you can make an artificial magnetosphere with satellites

It's actually feasible to terraform Mars. Humans would need to release very large amounts of sulfur hexafluoride and perfluoroalkanes into the atmosphere. Those inert and harmless gases will heat the planet, increase the atmospheric pressure by melting all ice caps

ok bud. and what exactly is the "feasible" method of releasing all those gases? and where is your proof that that would turn into an atmosphere the same as earth's (ie about 20% / 80% oxygen to nitrogen), and where is your proof that the atmosphere would stay put (ie not erode or dissolve)?

I'm just saying that it would heat the atmosphere and melt water. The conditions of the Earth roughly 4 billion years ago

bro our air was formed from the volanic gases and gases from plants.

how will we ensure the same gases are released in the same way on mars.

and if mars' gravity and magnetic field are different then exactly how will it hold the same molecules in place?

All reasonable concerns. Our planet sadly loses a lot of hydrogen, too. 3 kg per second. But since we are obsessed with terraforming other worlds, we need to decide which one: Venus or Mars

we're not gonna terraform anything. you'll find out eventually. as it gets closer.

Well the atmosphere staying put bit is easy, mars has 2/3 earth's gravity, it once had a thicker atmosphere, and was lost over millions of years. So at least there's that.

Obviously the getting the right atmospheric mix and density requires us first to have automated mining in space, which we haven't even started yet.

but that's all you actually need to terraform mars. that and a century or two to complete it

bro you said a century or two.

we can build an underground base in much shorter time span.

in two centuries we'll have underground base on mars, jupiter moon, saturn moon, uranus moon.

oh i well agree. just pointing that terraforming is a doable project

Here we go being reasonable again. Don’t tell elon tusk
