They realized Mars is bigger than a Stadium
Then crash comets and asteroids into it to make more.
Introduce microbes that can break down the soil and release some gas.
Use technologies you haven’t considered yet.
Make new Technologies.
Never give up, never, never, never, never give up/
Of course, it wouldn’t be called “terraforming” if it happened on Mars, right?
Wow, what a surprise...not.
“Manufacturing” means lots of power. Power that we are not capable of producing.
Duh! Just send a couple of V-8 SUVs. Job should be done in about a week. /sarc
Captain Obvious ping.
Might be easier to terraform Venus, a planet much more nearly the size and gravitational pull of earth. First problem is getting the excess heat radiated off, until the very hot atmosphere cools enough to allow the settling out of the volatile sulfur compounds (as sulfates), and the release of enough water to to act as a medium for heat moderation to still lower levels, within a habitable range for earth creatures. Seeding the Venusian atmosphere with “dirty snowball” comet material from meteors, organized in a vast engineering project, would vastly speed the process.
There’s a big difference between “breathable atmosphere” and atmosphere and temperature sufficient to allow heavily clothed excursions with supplemental oxygen. Getting it to the latter point would be relatively easy.
You have to have a molten core to generate a magnetic field. A magnetic field holds the atmosphere in place. The core of Mars cooled down millions of years ago to the point where it’s atmosphere almost entirely dissipated.
I read a book that suggested that Mars had had much water on it and that Mars was losing gravity and most of the water went away.
and we all know what happened when they Terraformed that planet in Aliens ,LOL
I think they can’t do it because of today’s paradigm. Work with what you have and exploit any oddity you can, such as the low gravity, thin atmosphere.
I sure would like to live long enough to at least see earth colonies living on Moon and Mars

Nothing about “Space Travel” is realistic “Using Present-Day Technology.”
Rushing space dreams will cost dearly in lives lost.

Probably cannot be done anyway. Mars has almost no magnetic field. This is probably why it lost most if it’s atmosphere, and cannot host much of a new one.
What gave you the first clue, Sherlock?
Terraforming is for TERRA - EARTH! Mars is not Earth. Different gravity, amount of sunlight, atmosphere, soil, water supply.
Using astronauts’ poop to fertilize your plants is going to get you killed.
But even if the temperature could be increased and enough oxygen could somehow be produced, Martian gravity is not sufficiently strong to retain enough oxygen for a breathable atmosphere. And since Mars doesn't have a magnetic field like Earth, cosmic and solar radiation would attack and contribute to the destruction of any atmosphere that is generated.
Earth, with its 1 g gravititational force at the surface, and its magnetic field protecting the Earth's atmosphere can retain oxygen. Mars has only 38% the gravity of Earth.
