How long would it take Mars to lose its atmosphere if we gave it one?

I've read that one of the reasons Mars doesn't (any longer) have an atmosphere is that it loses more gas to the solar wind than the Earth does, because its core has solidified and it therefore lacks a magnetosphere.
It seems unlikely that we could re-liquify Mars's core, or in any other way re-create its magnetosphere.
But we could theoretically supply Mars with an atmosphere through some combination of bombarding it with icy asteroids and possibly nuclear weapons.
So if we managed to give Mars a shirtsleeve atmosphere/environment, how long would it last before we needed to top it off with (carefully placed) further asteroids?

How long would it take to build an atmosphere around Mars?
Mars already has an atmosphere. It is not known how long creating an Earthlike atmosphere because we do not have the ability to terraform planets and we do not know all of the challenges it might hold.

Well are anybody living there now???? Well are anybody living there now????
How long can you stay on mars?
Considering no one has ever been to Mars, what makes you think anyone here would know the answer?
How long would it take to get to mars when your on a jet?
You wouldn't be able to make it to Mars on a jet in the first place.
What would happen if you took off your helmet in space while on Mars?
If you took of your helmet on Mars, you would begin to lose consciousness, start turning pale blue, and the liquids inside of you would start to evaporate and then freeze because Mars' atmosphere is 1/100 of earth's pressure, basically earth at 100,000 feet. Your fellow astronauts could save you if they are close to you and the spaceship because you have from 1 minute to 1 minute and 30 seconds to get pressurized oxygen before your organs shut down forever. Even if you survive, you would probably have permanent damage if you were exposed to the thin martian atmosphere for to long.

How can you live on Mars?
it is possible to live on Mars but to do this you would need an atmosphere, and to have an atmosphere you need gases. To make these gases (there have been discussions about this) you would need to build factories to give off green house gases and make an atmosphere, because Mars is extremely cold at night, then we would have to get people to Mars. This would cost billions and would take a long time to build the atmosphere.
How long would it take to travel to mars in a jet?
Cannot be done as the Jet cannot leave earth's atmosphere.
Are there craters all over Mars?
Yes, because Mars has a very thin atmosphere. If it had a thicker atmosphere (similar to Earth), most of the meteors would burn up. Since it has a thin atmosphere, most meteors strike the surface. Also there is very little erosion on Mars, so when a meteor hits Mars, the craters lasts for a very long time.
Can a planet such as mars that lost its atmosphere gain back an atmosphere again?
A planet could potentially regain an atmosphere as a result of the emission of gasses from volcanoes. It is highly unlikely that much will be added to the atmosphere of Mars, as volcanic activity appears to have ceased long ago.
What is the difference between the weather in mars and earth?
•Mars and earth both have 4 seasons but a year on Mars is about twice as long as it is on Earth, so the 4 seasons would amount to about 8 seasons on earth. • The temperatures on mars can be as low as -124.6 degrees Fahrenheit • Earth's atmosphere is mostly nitrogen and oxygen, where as Mars's atmosphere is made out of 95% Carbon-dioxide

How long is Mars in feet?
Mars is 4,200 miles in diameter. This would be 22,176,000 feet.
How long would it take to get to Mars using current technology?
it would take at least 197.456 hours to get to mars from earth
Why would humans swell up and die if they traveled to Mars?
The air pressure on the planet Mars is extremely low. A person exposed to such low air pressure would therefore be injured by the internal pressure of his or her own body, which is adapted to the Earth's atmosphere. Even aside from that, the atmosphere of Mars does not contain oxygen, so any person trying to breathe it would die from lack of oxygen. However, a person could live on Mars, just as a person could live on the moon, as long as that person remained inside a space suit or other air-tight container, which would provide the right kind of air pressure and oxygen to breathe.
Why cant you land on Mars?
It is physically possible to get humans on Mars with enough "gas" to get back home. But you have to wait for the perfect time for the Earth and Mars to line up (which is about 1.5 years). Once you get on Mars you have to then wait another 1.5 years for the Earth and Mars to line up again to get back efficiently.
