Can a Earth like atmosphere be created in Mars?

NASA conducted a feasibility study in 1976 that concluded it would take at least a few thousand years for even extremophile organisms specifically adapted for the Martian environment to make a habitable atmosphere out of the Red Planet.

Can we create an artificial magnetosphere on Mars?

Unfortunately, we can’t just recreate Earth’s magnetic field on Mars. Our field is generated by a dynamo effect in Earth’s core, where the convection of iron alloys generates Earth’s geomagnetic field. The interior of Mars is smaller and cooler, and we can’t simply “start it up” to create a magnetic dynamo.

Can Man alter Mars to make it habitable?

To successfully make Mars Earth-like, we would need to raise temperatures, have water stably remain in liquid form and thicken the atmosphere. To successfully terraform Mars, the atmosphere would need to be raised enough so that humans could walk around without spacesuits.

Is it possible to have an atmosphere on Mars?

My intuition tells me, unfortunately, no. Even with a magnetic field Mars is just not massive enough (1/10 the mass and ~0.4 the gravity of Earth) to hold on to an Earth-like atmosphere at Earth-like temperatures. You can see that on this plot of atmospheric temperature vs escape velocity, also reproduced on the right.

Could we terraform Mars into a planet like Earth?

Even then, since Mars has 38\% of Earth’s gravity, it can only retain an atmosphere of about 0.38 bar. In other words, even a terraformed Mars would be very cold by Earth standards and its air about as thin and chilly as the Himalayan mountains. In short, it seems very improbable that we could transform Mars into a more Earth-like planet.

Can Mars build up a global warming like Earth’s?

It would be a shame to build up an Earth-like global warming on Mars to release its carbon dioxide into its atmosphere, only for that atmosphere to be blasted away by the sun. Or would Mars’ gravity be able to hold on to it?

What would it take to build up oxygen on Mars?

If water could be excavated to surface, the plantation will lead to photosynthesis, gradually building up the oxygen level. Gasses and Liquids from Mars’ interior, so that in a few thousand years (millions), Mars would develop a thick enough Atmosphere to retain a liquid surface, and a thick enough atmosphere to retain an atmosphere.
