Features: The official adaptation of Jacob Fryxelius' famous board game. As explained above, melting the carbon dioxide at the poles of Mars would add around millibars to the atmosphere.

But we need much more than that. Even after melting all the dry ice, we still have around 20 millibars. So we need to dig up at least 10 tons of rock for each of these trillion square meters on Mars and find a way to turn this material into gas.

Crustal rocks average three tons per cubic meter. So we need to dig an average of three meters over the whole planet just to get enough material.

A more realistic way would be to liberate oxygen, hydrogen, carbon, and nitrogen by vaporizing the rocks we dug up in step 4 and releasing it. But we are talking about 1, trillion tons of rocks here.

So, we need more than 10, big nuclear reactors approx. We know how to build nuclear plants and how to vaporize rock. Resurrecting the Martian atmosphere with this method would still take a very, very long time.

Most comets are slow, they have long orbital periods hundreds of years. And we need a lot of comets. A comet weighs billion tons.

So we need to crash between 10, and 1 million of them into Mars. Despite being one of the main causes of global warming on Earth, carbon dioxide is not great for this job.

Because, over around millibars, its greenhouse effect actually diminishes. The 1, year plan seems to be a reasonable timeline.

If you utilize a version of Dr. An automated system to manufacture fuel on the surface of Mars would be included in the initial payload.

This would allow the visitors to Mars to have a fuel supply ready for the return to Earth at a later date. Humans would then take the six month trip and each crew would stay for 18 months, some may eventually choose to stay on the Red Planet.

Crews of Marsonauts would have an enormous responsibility to lay the groundwork for future Martians. The first visitors would set up the habitat modules and start the greenhouse work.

When each successive group arrives at the initial home base, all necessary groundwork will have been laid for them to immediately begin working on the next set of tasks.

This may include creature comforts. In order for the settlers to feel at home on Mars, the habitats would need to be comfortable and roomy.

We would like the crew to feel at home, which will help curb psychological concerns. The greenhouses must also be a top priority. Share Embed. Best Digital Board Game Add to Cart.

If algae or other green life were established, it would also contribute a small amount of oxygen to the atmosphere, though not enough to allow humans to breathe.

The conversion process to produce oxygen is highly reliant upon water, without which the CO 2 is mostly converted to carbohydrates. For both of these reasons it would be necessary to cultivate such life inside a closed system.

This would decrease the albedo of the closed system assuming the growth had a lower albedo than the Martian soil , but would not affect the albedo of the planet as a whole.

On April 26, , scientists reported that lichen survived and showed remarkable results on the adaptation capacity of photosynthetic activity within the simulation time of 34 days under Martian conditions in the Mars Simulation Laboratory MSL maintained by the German Aerospace Center DLR.

One final issue with albedo reduction is the common Martian dust storms. These cover the entire planet for weeks, and not only increase the albedo, but block sunlight from reaching the surface.

This has been observed to cause a surface temperature drop which the planet takes months to recover from. If this experiment works on Mars, they will propose to build several large and sealed structures called biodomes , to produce and harvest oxygen for a future human mission to Mars life support systems.

Research at the University of Arkansas presented in June suggested that some methanogens could survive in Mars's low pressure.

The four species that she tested were Methanothermobacter wolfeii , Methanosarcina barkeri , Methanobacterium formicicum , and Methanococcus maripaludis.

One key aspect of terraforming Mars is to protect the atmosphere both present and future-built from being lost into space.

Some scientists hypothesize that creating a planet-wide artificial magnetosphere would be helpful in resolving this issue.

According to two NIFS Japanese scientists, it is feasible to do that with current technology by building a system of refrigerated latitudinal superconducting rings, each carrying a sufficient amount of direct current.

In the same report, it is claimed that the economic impact of the system can be minimized by using it also as a planetary energy transfer and storage system SMES.

During the Planetary Science Vision Workshop [14] in late February , NASA scientist Jim Green proposed a concept of placing a magnetic dipole field between the planet and the Sun to protect it from high-energy solar particles.

The paper abstract cites that this could be achieved by a magnet with a strength of 1—2 teslas 10,—20, gauss. Simulations indicate that within years, the planet would be able to achieve half the atmospheric pressure of Earth.

Without solar winds stripping away at the planet, frozen carbon dioxide at the ice caps on either pole would begin to sublimate change from a solid into a gas and warm the equator.

Ice caps would begin to melt to form an ocean. The overall energy required to sublimate the CO 2 from the south polar ice cap was modeled by Zubrin and McKay in This is considered the most effective method, though the least practical.

If using powerful halocarbon greenhouse gases, an order of 1, MW-years of electrical energy would be required to accomplish this heating. However, if all of this CO 2 were put into the atmosphere, it would only double [30] the current atmospheric pressure from 6 mbar to 12 mbar, amounting to about 1.
