Will Mars be terrafromed

As the subject says.

Will mars be terraformed in our lifetime?


I wish I could live on Mars..

Re: Will Mars be terrafromed

mariano2020,

First off, welcome to the New Mars Forums.

The short answer to your question is "no" if we're talking about terraforming at a global scale, mostly because Mars doesn't have enough atmosphere to work with.  However, that also depends upon how you define terraforming.  If we were to enclose an entire canyon on Mars to make it habitable to humans, does that still count as terraforming?

Importing enough resources from other planets or asteroids is not feasible using current propulsion technology.  However, if we built the machinery required to generate sufficient power to liberate Oxygen and Nitrogen from the various minerals present in the Martian regolith, then that could feasibly produce a habitable atmosphere for a very large enclosed structure.  Terraforming the entire planet would require Nitrogen in quantities that simply aren't available there, so far as we know.  Only the gas giants could feasibly provide enough Ammonia for the Sun to eventually convert into Nitrogen, but we're still left with the problem of transporting it to Mars.  Unfortunately, thick clouds of Ammonia would also tend to make the Martian atmosphere even less friendly to human life.

Re: Will Mars be terrafromed

We need earth amounts of energy, and time to unlock what we need to make mars more earth like.
After thats none stop building...
In time mars will need stabilizing once more so long as we continue to make the earth surface energy to mars difference.

Re: Will Mars be terrafromed

What about the magnetic fields? I read somewhere that earth has magnetic fields that protect us from radiation. Doesn’t this mean that even with tech we might never be able to replicate this magnetic field?

Note: I might be wrong

No, but substantial human-friendly  spaces with breathable air and Earth like vegetation can be created on Mars in the next 50 years so humans can enjoy living on the planet.

Re: Will Mars be terrafromed

It appears that there is a question which seems not sustainable....
Best region for life on Mars was far below surface

"Even if greenhouse gases like carbon dioxide and water vapor are pumped into the early Martian atmosphere in computer simulations, climate models still struggle to support a long-term warm and wet Mars," said lead author Lujendra Ojha, an assistant professor in the Department of Earth and Planetary Sciences in the School of Arts and Sciences at Rutgers University-New Brunswick.

Seems the input wattage getting to mars is the issue for keeping a warm mars.

Re: Will Mars be terrafromed

Mars needs to amp up its field to aid in maintaining its atmosphere if we are going to be able to not need space suits and domes on the surface.
