I don't think anyone is asking the right questions. They are caught up in the romanticism of going to Mars. Are we sure we even understand the mission? On the Mars One site they don't have a roadmap beyond sending a 2nd team in 2026. Is terraforming even on the menu? I think surviving is all they will be doing.
I was skeptical of the Mars one thing from the start. For one, 6 billion dollars is unrealistically low.

I think fusion. Fusion is when the nucleus of two light atoms merge releasing energy in the process. Fission is when a large heavy atom breaks apart releasing energy.

Hydrogen and helium are easy to fuse, where heavy elements like uranium 235 break apart when a stray neutron enters its nucleus to form 2 new atoms.

Many people believe Mars has no atmosphere, which is not true. It simply has an exceptionally thin atmosphere.

I don't think that maintaining a magnetosphere would be imperative, but starting with one would be important.

Once a thicker atmosphere is formed, there would not necessarily be a need for a magnetosphere.
A magnetosphere does shield against solar wind which are charged particles from the sun, though electromagnetic waves, like, IR, light, UV, X ray etc would still get through.

I am also not sure how we would create one large enough to engulf the entire planet.

Also, Mars' atmosphere is so damn weak, it might as well be non-existent compared to Earth's.

Ok, the second most abundant gas on Mars.

Both the northern polar cap (Planum Boreum) and the southern polar cap (Planum Australe) are thought to grow in thickness during the winter and partially sublime during the summer. In 2004, the MARSIS radar sounder on the Mars Express satellite targeted the southern polar cap, and was able to confirm that ice there extends to a depth of 3.7 kilometres (2.3 mi) below the surface. In the same year, the OMEGA instrument on the same orbiter revealed that the cap is divided into three distinct parts, with varying contents of frozen water depending on latitude. The first part is the bright part of the polar cap seen in images, centered on the pole, which is a mixture of 85% CO2 ice to 15% water ice. The second part comprises steep slopes known as scarps, made almost entirely of water ice, that ring and fall away from the polar cap to the surrounding plains. The third part encompasses the vast permafrost fields that stretch for tens of kilometres away from the scarps, and is not obviously part of the cap until the surface composition is analysed. NASA scientists calculate that the volume of water ice in the south polar ice cap, if melted, would be sufficient to cover the entire planetary surface to a depth of 11 metres (36 ft).

What happens if they get people on Mars, and they don't plan to bring them back? Answer: They have to send supplies and food into the foreseeable future, correct?
Are the astronuts supposed to breed and multiply, or just die of old age like fish in an aquarium? I'm unclear on the actual mission. If they breed you gotta keep sending that baby formula and diapers.
Very carefully.

I'll admit I'm not sure exactly how we could create that. There are a number of theories but at this point they are all theories. I'm in favor on pelting the entire surface of mars with small rockets with compressed flourines for about 20 years.

I'm not saying it's possible to start the terraforming process today, but if they can email a ratchet from california to the space station, and then 3D print it out, then I don't think it's unrealistic to think that terraforming Mars is too far away.

Another possible theory that I'm not in favor of, is using lasers to change the path of asteroids to impact repeatedly on the poles in order to raise the temperature. Surprisingly, scientists estimate it would only need to be raised by about 4 degrees kelvin in order to start a planet wide greenhouse reaction. You could then plant lichen all over the planet, or really any dark microbial life, I just don't know of any other than lichen that could survive it. As the planet heats up, with a little bit of H2O the lichen could begin the process of converting the Co2 into oxygen. Probably not enough to live on, but perhaps enough to feel like you were at the top of a very very tall mountain here on earth.

I'm guessing that any terraforming scheme we could think of would be either preposterously expensive or only work over geological time scales. Probably a combination of both.

I kind of see it as the equivalent of trying to launch an interstellar mission with current or near-future technologies: by the time the spaceship gets to its destination, we'll be able to launch another one that will pass it.

I watched Monday night's episode of Castle and it was dealing with a murder on the 'simulation' stage of a setup very similar what the OP's friend is going thru.

Thought it was an amusing connection.

unless there is some huge desparate reason to get off earth, ie moon experiencing orbital decay, planet exploration will be limited to robots.

what if we just shipped all the undesireables over there on a big space ship, and let them establish their own colony with their own laws (if any)?
we check on them in 30 years and see how society has evolved/devolved

is this ethical?
