Do you think it is possible to make Mars habitable?

Answer 1

I seriously doubt it.

The magnetic field is next to nothing but even more important is the gravity of Mars and its distance from the sun.

Mars has much lower gravity than Earth and is over 1.5 times farther from the sun than Earth. If we were to supply Mars with enough air today so that humans could breath at the surface, the low gravity and solar energy acting on the upper atmosphere would cause the air to evaporate away into space very quickly and leave Mars once again in the near vacuum state it is now. I doubt that enough vegetation could thrive there to keep the oxygen we need available. Much of our air comes from the oceans and the green algae and other plants.

Any people living there would have to live inside special protective enclosures.

Living conditions comparable to Earth on that planet is a tough act to follow.

Hype about such concepts is necessary to keep the research dollars flowing, so even if they know it can't be done, NASA isn't going to loudly proclaim it, if for no other reason, just to keep the support of the public and the funding of the government who generally doesn't know any better.

Scientifically it seems like a pipe dream to seriously consider terraforming Mars in any way that is self-propagating. Such a task would be far beyond our combined international resources.

We may go there some day, but I doubt that at any time in human history we'll ever be able to spread a picnic blanket by a river and enjoy a nice day basking in the sun on Mars.

This may not be what some people want to hear, but it's the most scientifically realistic scenario at this time.
 

Answer 2

Mars can have colonies of people, but unfortunately "terraforming" or making the whole planet usable for humans is nearly impossible. The first problem is that Mars doesn't have a strong magnetic field. This field helps deflect on teh solar wind. The radiation and the ability for the solar wind to push molecules away prevents Mars from having a thick atomosphere and is rather hostile for humans. Mars is also much smaller than the Earth, so the lack of gravity also prevents the planet from holding a thick atomosphere.

If we were able to pull enough astroids on to it (as well as crash both it's moons - Phobos and Deimos) into it, then we might be able to get it to be a kind of an Earth clone. But with all that energy, we might as well make a very large spinning cylinder and live inside it.

Answer 3

Be terra forming it, yes.
It will probably take steering ice comets to impact Mars, enough to give it the kind of water we would need.
I don't think that atmosphere created that way would dissipate very quickly. The belief that many people have that Mars is with a low atmosphere is because of low gravity is probably not correct. If that was the reason, then Venus could never hold an atmosphere that is 90 times as dense as earth's, despite being identical in size to earth.

Answer 4

No. But it may require significant genetic modification to humans to produce a species that could live there. Even then there are some serious terraforming questions that currently have no solutions.

Without a moltant core there is no magnetic field on Mars. That means any atmosphere is subject to abuse from solar winds and would be continually lost to outer space.

It would be far easier to genetically modify plants to survive on Mars than animals or humans. They need far less CO2 than animals need oxygen. So less changes to the atmosphere would be needed.

Answer 5

All you need is a good mix of Carbon Dioxide and Oxygen and humans should be all set.

It'll depend about the other species, maybe they can come to Mars later or something since Mars can not be turned into an exact replica of Earth.

Answer 6

Maybe in the far future, but as of now, we don't have the proper technology to habitate Mars in a practical way.

Answer 7

Mars has no electromagnetic field to protect any atmosphere we create from being stripped away by the solar wind. All colonies would have to exist under air tight domes unless we can fire up the planet's core again, which is doubtful at best.

Answer 8

No. And anybody that tells you that this is realistic either works for NASholes, is a Star Wars or Star Trek fan, or is just stupid. The idea that we might get natural resources from other planets makes some sense but making another planet home is just pipedreams that will never happen, and if it does it will be a select group of people, not you or me.

Answer 9

Why would we do that? If we want to make homes in space, it'd be far more effective to make space colonies: picture enormous space stations, miles on a side, spinning to simulate gravity.

Google "Gerard O'Neill" for more information on this.

Compared with the effort and uncertainty in terraforming an entire planet, this'd be much more to the point - and take far less time.

Answer 10

one million. What might want to the great air pump pump? Air from Earth? it truly is an particularly lengthy hose, and we want our personal air down right here. 2. Algae like liquid water. have not stumbled on any of that on Mars yet. 3. certain, even if it truly is and an extreme priced proposition. 4. shall we, yet do we favor to infect that ecosystem earlier we've thoroughly surveyed it? we are particularly careful to sterilize or disinfect any spacecraft we deliver previous Earth orbit to circumvent the type of an infection.
