Note: I have corrected the lowest temperature for matabolism for Lichen which I had said was 20 degrees Centigrade. It is -20 degrees Centigrade.
Water ecology depends primarily on micro-organisms as it's base. Any ice covered bodies of water or later open water habitats might do quite well with micro-organisms, and perhaps later animals.
High Arctic and favored places in Antarctica primarily have lichens and micro-organisms.
The salt pans of the mid latitudes of the southern hemisphere might receive moisture in the form of snow, and also by absorbing moisture from the atmosphere, and they might even be fed water by gravity feed from the south pole. Those could support microbial mats.
I have been thinking however, that perhaps there might be a solution for some higher plants that have Nitrogen fixing bacteria in their root systems.
If such symbiotic organisms could be altered, perhaps they could make it. The Nitrogen fixing bacteria would have to work harder to fix Nitrogen for the plants, so they would have to be engineered to be able to do so, but as a consequence they would require a greater gifting from the plants in terms of energy. So the plants would have to have their role altered so that they did provide more energy and nutrition to the bacteria. Such plants would not really be able to make it though if the nights were repeatedly colder than perhaps a few degrees below zero. Those conditions are too cold for the plants, and also that tends to allow freeze-thaw actions that churn the soil and damage the roots. An atmosphere of 100-1000 mb would not warm Mars enough to make the equator suitable for such plants, unless some greenhouse gasses were employed, super greenhouse gasses.
However at the poles with such an atmospheric pressure, also due to Mars year being almost twice as long, it might be possible that a relatively frost free mid summer season of 60-120 days could occur once each year. So annual plants might work out.
I do think that it is possible that Nitrogen bearing rock layers might exist below the upper layers of materials ejected from super volcano's as the planet began to freeze and dry up. On the other hand could those super volcano's have caused an ejection of much of the atmosphere of Mars?
If the layers do exist, it would be quite a task to get the Nitrogen out of them. Perhaps ground currents could liquify those layers, causing a volcanic process? But that would require a lot of energy. Perhaps biology could liberate the Nitrogen, but that would take a lot of time, and I would think organisms created to do that would require that the layers be subjected to fracking, and that energy bearing chemicals would need to be injected. Perhaps Hydrogen. They might use the Hydrogen to power their life processes in part, and perhaps break the Nitrogen out of the chemical bondage they were in.
For farming, it should not be that hard to create inflatable domes, and inject extra Nitrogen into them, so that a wider variety of Earth crops could be grown. This would also help with warding off night freezing in the lower latitudes.
I am not against other methods to be considered for adding Nitrogen to Mars, but I think every form of adapting to what is actually there should be explored and exploited first.
Getting back to topic, stem cell work, where cells missing are replaced is another of the seven categories of damage that can be addressed.
Going beyond that and presuming the Mars might have a pressurized but still toxic atmosphere at some point, I might speculate on a placenta type implant perhaps having biological and mechanical characteristics to store Oxygen in your body.
Crocodile blood? Or nano storage chemicals. Put the new organ in your abdomen somewhere, and maybe able to hold your breath for 10-15 minutes?
I kind of set that up I guess. Why I did it was to emphasize that I though that with life extension, later it might be reasonable to expect that some of the financial burdens of retired people on society could be reduced. However there are people out there that would say OK, put them to work, take away their SSI, but they would not then divert money to life extension. I am convinced that our government would be investing well to give grants to some of the people and organizations working on these issues, provided that they also did not interfer with the work, or load the system down with deadheads (Because they want it to fail).
But if they were rational they would see that most people if they were reasonably healthy would like to work a 20 hour work week even late in life and have extra money, and a feeling of worth, while not being burnt out from an excessive work load.
That's good information, but I would make the point that there is a significant energy source in visible light.
But I wonder if a life form that likes to grow in UV only could be found? If something likes very hard radiation then why not UV?
Another concern is how adapted is an organism to Mars conditions as far as moisture availibility and also temperature ranges.
Some Antarctic lichens, can motabolize down to -20 degrees C, and can absorb water vapor into themselves from ice, frost and snow therefore perhaps not even requiring liquid water phase external to them.
Still and open mind should be kept on this.
Telomerase:
I actually saw something on T.V. where an old persons cells that were weak and blobby in appearance, after having the Telomerase redone, took on a young and apparently more healthy appearance.
However I think you would want serious treatments for cancer, just in case it went wrong some of the time.
The irrational resistance to these changes, will eventually wane I think. From a practicle point of view, what if instead of putting people in assisted living, and nursing home situations, and possibly end of life very costly medical procedures, persons could be rehabilitated to work 20 hours a week? I think that would really turn around American debt problems.
The following is not for or about you Robert.
However don't get messed up on this. My entitlements are because I am am entitled. In other words, guess what I/We the Baby Boomers are becomming the owners. How about that. What should I think of an investment advisor, that mandates that I invest in a fund, and then when the fund matures, wants to keep the money, because they spent it? I am going to be OK, but you see we have a problem here Houston.
It seems that there is a class of people who think of us as livestock, when they should be thinking of us as the OWNERS.
I have watched some of the video. It's also good. It's getting late though. Maybe another day for the rest of it.
All of this could also relate to space activities, since a improved breathing system could make the habitation of Mars, eventually more probable.
Of the seven items that the Sens foundation has helped to speak about as being the classes of damage that cause aging, one is cells that don't die when we would want them to. Some cases are cancer, some are just old cells that sit around being toxic.
I did think about using viruses to attack cancer a couple of days ago, and sure enough it looks like a lot of research like that is happening in Canada. You can look for it yourself if you care to. I choose not to mention the political entity that did a lot of research on giving bacterial infections a viral infection, but it does not exist now. Please no politics here. With radiation a hazard in space, then treating cancer with viruses has to be of interest.
I am thinking about this some more and thinking in fact what if you could give a human cell with a viral infection a second viral infection.
If as in the case of viruses selectively attacking cancer cells, you could get a second infection to attack cells already infected another disease, such as HIV or a more contagious illness, then the second infection could either kill the cells incubating the first virus, or render it's reproductive activity damaged, or attract the humans immune system to attack the double infected cells,
Where the first infection might burn slow, so as not to quickly kill it's host materials, so that it can spread it's genome. The second human created infection could be like wild fire, designed to find it's host cells and kill them as fast as it could.
I do believe that he said Vitamins would not do it.

It would not be polite for me to not reply, so I must.
I will leave the issue of personal indulgence for the high masters to settle, with some apology for the trouble it might cause.
My post was to indicate that unless the inheritors become something other than human, they will fall prey to the same social errors.
For many, it seems this is not an issue, anymore than charging your personal line of credit to a point where your life style is forced to change. Most things are beyond my pay grade, or if I am wise I say "I don't know". ![]()
Louis,
An alternate plan is to cover areas with water at a temperature warmer than freezing. For fresh water 32-39 degrees Fahrenheit / 0-3.88889 degrees Celsius.
The current conditions are unfavorable for a stable ice cover for such bodies of water even at high latitudes, but since much of the necessary water would have to come from the polar ice caps and the south polar ice cap holds an estimated C02 content that could boost the average surface pressure to 11 mb, more favorable conditions could be supported. I am not saying that 11 mb is the limit, is just a good number to start with.
Water placed over a surface area of perhaps up to 1/2 the area, would conduct heat into the ground at a more rapid rate. The ice cover would be a good thermal insulator. What is then needed is to put heat energy under the ice into accumulating bodies of water. The accumulation would have to come from the melting of polar caps and ground ice.
Very harsh environments at the edges of the polar ice caps, but seasonal sunlight is available. I would consider investigating the possibility of placing a mirror system in the L1 location for the Sun / Mars built from materials from the two moons.
And also the release of the super greenhouse gasses explored for terraforming on this web site.
When possible it would be used to melt a first ice covered pool, which would join very near the edges of the ice caps, so that even though the pools surface ice would tend to evaporate, replacement water would be obtained from the ground ice below the pool, and also from the melting edges of the ice caps.
Until the pressure is increased, liquid water could only be generated by shining light through an insulating ice layer, and melting the ice below. Rivers and streams are currently possible on Mars, but they must be ice covered, and of course the water must be cold, and you would have keep a lot of melting happening to maintain them. But seasonally, it would be possible even if the atmosphere is at the current pressure.
Upon creating pools of sufficient size to grant protection to a population of humans through Martian winters, humans could be added to the site, and they could build power plants where seasonal solar power would use concentrating mirrors to generate steam which would be run through turbines, and would be quenched into the liquid of the lakes. This would both provide electric power and also heat the lakes. If fresh, the bottom layers can be heated to 39 degrees Fahrenheit / 3.88889 degrees Celsius. If somehow the water was very salty (Presumed remnant of ancient oceans salts leaching into the water), then the bottom waters can be heated to 70 degrees Fahrenheit + / 21.1111 Celsius +.
The human population might be mostly seasonally migratory. Obviously if sunlight is entering through the ice and melting water, then conditions for some aquatic life are supported. As the pools expand into seas, the ground below them should warm up and release gasses. Those would eventually migrate into the atmosphere, increasing it's pressure.
The ice surface presumed to be relatively flat will support vehicular traffic above it and perhaps traffic below the ice.
Mining might be negatively impacted since mineral deposites might lay below shallow seas. But it was going to be hard to do shaft mining anyway, since a leak in your mine would depressurize it. In this case, liquid above it might leak in but in many places on Earth, water has to be pumped out of mines. Another solution would be dykes, to surround a mining area and keep the water out.
Also for a long time permafrost would lay below the seas, and any water leaking in at a relatively slow rate would tend to freeze, and so seal the leak, so your mine would not be flooded.
For stip mining however, dykes are needed I would think. But maybe many important mineral deposites at that location will have been mined out before being flooded, or maybe they would not be in the flood areas.
OK, I confess, that did not quite make it, as it implied that the trolly car could somehow complete the circuit through the ground.
The trolly cars would have to have two conductors, one a main of either polarity, and a lesser one to power the trolly car. The ground would serve to conduct power to towns located at a place of a resource such as a mineral.
I am trying to minimize the use of copper or aluminum, while serving your desire to heat the ground.
That all I have at this time.
I don't want to discourage an eager mind, but your objections are also necessary. I am thinking Hydrogen bombs, where fuel is obtained from Mars where heavy water is concentrated X5?, and Lithium might be found in the salt pans. I am also thinking Helium 3 from the Moon, to reduce the radioactive results. But it needs some more thinking.
Louis,
The best I can do is trolly cars. If Mars was a cue ball in elevations, then a gridron of trolly car cables might make sense. But in the Northern Hemisphere is the 1/3 of the planet which is flat. Perhaps there as a start. Solar power plants where it is efficient, and electrical conductors to serve multiple purposes. To serve your desires, I propose that one conductor is copper or aluminum the other ground. To implement that the grounding rods must be very robust. Like a pyramid. Copper at the top, then Aluminum,
then other lesser but broader conductive masses, down to Carbon and then the soil.
Advantages: If I am in a trolly car, and my propulsion engine blows up, perhaps I can still run life support from the cables until rescue. If ground currents are flowing through the soils, then perhaps they are heating up from it.
Also, if my energy budget from the trolly cables permits it perhaps I can emit a power beam into the soil to heat it more.
That's what came up on your request. I hope someone else can do better.
Note that you come from an entirely developed culture and infrastructure, and so would be the above proposed. Before that would be required transport with on board energy methods, those devices required to build the trolly system.
Just a wicked guess ![]()
In an idle society with plenty, a surplus of persons who can produce must be present. (Persons or robots, and robot servants)
In the case of humans stone age motivations are still drivers for motivations.
Breeding practices would be altered. I speculate that in a harsh situation, I male may prefer a robust woman who can help with hard labors (Old farm life for instance).
Otherwise the males on average may prefer smaller, more child like females (Larger head to body ratio, less hair, smaller size, graceful, etc.) with secondary sexual features present.
For the female in a technological society where material goods are abundant, and therefore technological capable males a surplus, will most likely prefer a type A male with larger body, so that she can obtain additional material goods from a male that is good at obtaining material goods from other producing persons.
If a society is male dominated, then the offspring will be more like space aliens that we fantasize about.
However if males continue to have their instinct to mate, and females as is usual have a great deal of say about who their mate is then type A's with physically dominating bodies, and socially manipulative person skills, will grow in numbers. The domination process will require that technological males put their efforts towards military skills to be competitive in procuring material goods, to attract a female.
In terms of social organisms that help foster this process is some religions where a large attending population of females who are naturally gifted at the manipulation of people. One manipulation is who may mate and how. Adding some frustration can be helpful
Then determining or influencing which males are allowed to occupy apparent positions of power.
Business has not been like that but we do now have in our business process an increase of religion like regulation in business to make it possible to integrate a greater proportion of females into business. It is a lesser effect. However, business has been changing from manufacturing oriented processes to distributive processes, where technical skills on average are valued less (Unless they are very good), and people manipulation is honored more.
When the population exceeds the material goods, then there will be war and the slaughter house, often type A males killing each other off.
Then a time constant is established where periodically there are too many stone age type winners, and another war will happen as soon as a spark sets off the fuel of excess aggressors.
Familiar?
I can offer encouragement and state that you appear to be a very useful addition.
I will only be able to converge with you on things sometimes, as our methods are so different, and your level displayed is far beyond me.
However, I think I see your notion.
An energy generating trigger device.
An energy generating fusion device.
An energy consuming 1 Si to 2 N fission process?
I don't know what the limit could be on how much atmosphere Mars could hold and not leak more than it does. I am betting it is a lot.
A thicker atmosphere could hold heat in though and make the upper layers cooler which could inhibit leaking, but I believe that most losses are due to solar wind, and not thermally driven.
http://www.scientificamerican.com/artic … -at-night/
That and either Liquid/Solid C02, or Liquid Air (On Mars, mostly the gasses that are not CO2).
Heat from the environment + Stored hight temperature Solar Molten Salt Heat + Steam Power
If you have a "Steam Jacket" surrounding your molten salt you reduce heat loss to the universe, and also it can be noted that the ambient thermal conditions on Mars will usually add heat to CO2, and will almost always add heat to Liquid Air (On Mars, mostly the gasses that are not CO2).
Of course water could be the working fluid as well, but is precious in many locations on Mars. You might want to be able to recapture some of it after it condenses, but that would reduce power most likely.
I agree that salts might not be in a easily collectible form or very abundant on
the Moon.
I do think that it might be considered to manufacture salts in part from Lunar or
other sources.
Probably some of the components would have to come from Earth, at least initially,
for economic reasons.
I think that just picking up the dust of the Moon is the first easiest mining
that could be done, and it could be largely automated. But that would not
procure all of the chemicals to manufacture salts. (But it might be preferable
to bringing all the mass up from the Earth).
This propulsion system is just a contender, and might be discarded for something
better, but if it is considered useful instead, then obtaining salt mass to
expel has to be of interest, and obtaining it from the Moon would be transferable
to other solar system objects in many cases.
*Even though the salt may be liquid, the article indicated that expelling particles.
I presume that the liquid becomes a spray, and at that point those particles are
expelled.
But I will leave it there, I have passed my ignorance limts on this one.
So, can we catch comets by putting salt on their tails?
I have been thinking about the fact that you have reasonably accepted salts as propulsion mass, in association with the ion thrusters referenced in
this thread.
I always hope for a way to procure mass from non-Earth objects in such a way to be helpful to the cause.
Moon dust being the most easily obtained portion of Lunar resources, and many salts apparently being partially composed of metals, I see a
potential.
This also could be done from the moons of Mars, and of course Mars itself has salt pans, and salty soils.
Don't know if these thrusters can use NaCl, but I do know that there is Sodium and Chlorine on the Moon. I don't know if much Sodium is in the dust,
and I don't expect much Chlorine in the dust, but I do believe that there are other metals that could be used to in part create salts.
I would have to suppose that the Chlorine would have to come from Earth, and possibly Mars, or a substitute for Chlorine which would also make
usable salts. I am sure getting Chlorine or Fluorine into orbit would be a have some danger involved.
There are also Iron Salts (Which I don't know are or are not usable)
http://www.sigmaaldrich.com/materials-s … e=19295340
Magnesium Sulfate looks interesting since it has less dangerous components, but I of course do not know if it is suitable for this propulsion
system.
http://en.wikipedia.org/wiki/Magnesium_sulfate
Anyway, if it is a good propulsion system for some aspects of space travel, then perhaps some components of the salts can be obtained off planet,
at a reasonable cost very soon, and then of course with a more advanced space industry (If ever), perhaps all the components could be obtained, from
the Moon, and then other locations.
Of course Mercury, Europa, and Enceladous likely have those, but that would be very very advanced space industry.
http://en.wikipedia.org/wiki/Urea
Urea or carbamide is an organic compound with the chemical formula CO(NH2)2. The molecule has two —NH2 groups joined by a carbonyl (C=O) functional group.
Urea serves an important role in the metabolism of nitrogen-containing compounds by animals and is the main nitrogen-containing substance in the urine of mammals. It is a colorless, odorless solid, highly soluble in water and practically non-toxic (LD50 is 15 g/kg for rat). Dissolved in water, it is neither acidic nor alkaline. The body uses it in many processes, the most notable one being nitrogen excretion. Urea is widely used in fertilizers as a convenient source of nitrogen. Urea is also an important raw material for the chemical industry.
Note that urea would be useful for a "Chemical Industry" so developing the capability to manufacture it would not be only for this system I will elaborate on further.
I have to notice that it uses the phrase "practically nontoxic".
However, like salt it would damage sensitive organisms if at a high concentration, by dehydrating them I think. One way a fish compensates for being in a saltier environment is to retain urea (I seem to recall). That then helps it retain water.
So, the more you used it as an antifreeze, the more harsh the solution to life, but as in salt tolerant Cyano Bacteria, I would hope to find a photo organism tolerant to a urea solution.
But the antifreeze notion is not essential to the suggested process. I also wanted the urea as fertilizer.
In humans urine expulsion is done to rid the body of excess Nitrogen. Fish don't urinate they Ammoniate. But to preserve water our bodies bond Nitrogen into Urea?
As for the structure.
The wall could be made of bricks, or a metal hoop, it's ends pushed into the ground, and a reflective sheet attached to the plane of the space enclosed by the hoop and ground.
The "Tarp" that is attached to it would allow visible light in, but protect the interior from UV. When it wore out, it could easily be replaced. If it ripped, it could be taken down to repair/patch or recoat with UV protectant. It also could be folded and brought into a pressurized repair shop.
The bladders similarly could be deflated and folded up and brought into a repair shop. I would imagine that they would have quick disconnects, to allow fluid transferring ducts to fill and empty them when the process was running. Further they could be mass produced.
A weakness in the system would be the conduits that would transfer fluids in and out and through the system. Placing the tubes under the bladders would provide some protection from cold temperatures. Other means such as insulation and perhaps heat tapes could be used.
The pressurization of the bladders need only be enough to keep the water based solution below a boiling point, unless you want to boil the water and extract water vapors.
A system that used manufactured Urea could also handle human urine I would thinks, so having a separately ducted subsystem to recycle it to bio fuels, does not seem like a bad option.
I will do some follow-up conversation on Lichens. and micro-organisms.
I begin by using you best case value of 11 degC as the upper limit for useful moisture, and that applies as you have said to the lowest surface of Mars, Hellas Basin as you have said. So I agree to the statement that about ½ of Mars can support surface life with liquid moisture as is, with no terraforming.
That article I referenced however, adds that -20 degC is the lower limit for some hardy lichens from Antarctica.
Tests done by Europeans, Germans I think, indicate that some of those Lichens and also Cyanobacteria, have a rough time making it out in the open, but in cracks in dirt or cracks in rocks, conditions seem to be good enough for them to make it. They said that it would be because of protection from radiation, and I believe that is likely a factor. I would imagine the spectrum of light at the surface can be divided into three factors:
1) Warming (They must all serve to warm).
2) Photo generative non-damaging. (Some of the visible light).
3) Damaging (UV).
Perhaps Lichen and Cyano have a saturation level for 2) Photo generative non-damaging light. If so, being in a crack would attenuate all wavelengths of light in most cases. However if some is reflected light, perhaps being in a crack would also change the amount of particular wavelengths, since some wavelengths would be absorbed and some reflected. At any rate if a photo organism had already gotten as much useful light as it needed, not going above that level, would also limit the amount of harmful wavelengths.
Salt: Lichen would not benefit from having salt in the crack. It is typically not very salt tolerant I have read. Cyano bacteria might benefit from salt, which would help retain moisture, and would keep moisture liquid at lower temperatures. So Lichen can deal with temperatures down to -20 and still metabolize, but Cyano bacteria would more likely dominate salty areas.
The thermal characteristics of cracks might be important as well. Cracks in rocks or soil may have a higher thermal inertia, and perhaps have a lesser temperature swing than other locations. If the variation is primarily between -20 degC and 11 degC, (In Hellas) then that would be optimal for a moisturized situation supporting metabolism. That I presume would occur at some time during the day, and not be likely during the night. However the night may be helpful to drop the temperature in the cracks below -20 degC, and make it possible for condensation to occur in the crack primarily after the lowest temperature is achieved. I would expect that as the open areas begin to warm up, unless sunlight is directly shining at that time into the crack, the crack would be of a lower temperature, and would receive donations of moisture from the open areas, which would be loosing moisture.
The experiments conducted, trying to simulate the current ambient conditions, suggest that in protected areas the most hardy lichen can do OK, and it can be supposed that if you could get such lichens, and perhaps also Cyano bacteria started in those protected areas, they might eventually tune with evolution to be even better adapted. But without interventions I cannot speculate how long that would take. It would actually be wise to have a chamber on Earth where that evolution can be stimulated, different strains of the Fungi, Cyano Bacteria, and perhaps Algae provided, the survival of the fittest. But perhaps a bit of genetic engineering could be used as well.
I would also like to see an experiment where 11 mb was employed and also 22 mb. If the average of Mars was elevated to 11 mb, then perhaps Hellas in it’s best case would be 22 mb (A gestimate).
I would also like to see how the organisms respond to dry snow accumulation in the cracks from simulated snow falls and wind, and how they would deal with dust and also salts.
Antarctica’s Lichens environmental preferences have been defined well enough.
I know you don’t require this, but maybe some other readers do:

Well, I can't just leave Josh surrounded by arrow flinging barbarians. He has been quite polite which must be painful ![]()
Are you saying the wheel has no value? I have had many jobs. Among them I was a miner. Drippy dirty. Play with electronics and electrical devices there and understand natures will. I have also worked for a more diverse entity. Even so, murphy's law applies.
I recently carried a heavy load down a staircase, tripped and did a good wack to my head. "Explative Deleted" happens. If I was in a 1.7 gee gravity field, likely very dead.
Respect nature. Yes, wheel chairs down stairs, not so good. Devices that help crippled people, good!
Unless you choose to alter the human body plan, it's structure and create an alien, you must obey the laws of gravity. Trust an exoskelton? Oh sure. We just buy this new crap, and it's tra-la-la Ha Ha!
Blood pressure. I'm lying down in my bed and getting up, or I am emerging from a swimming pool (Because my spinal disks are killing me). I stand up, and what the **** I faint in a 1.7 gee situation. Maybe I am not dead, or I don't have to go to a hospital for observation, but if so I am extremely lucky.
Why not a transformer wheel chair if you are so worried? Or maybe a regular wheel chair as a intermediary between lying down or being in the swimming pool. After my body has adjusted, then I can put on the exoskelliton. Otherwise just genetically engineer the people/creatures that are going to live on the "Super Earth".
You have expanded the information, and in reality we have pretty much the same tools. I decided to plan on the basis of a value for CO2 ice in the South pole that would actually move the average from ~5 mb to ~11 mb. I agree with your moisture analysis.
You will notice that I left open the option to import Nitrogen (Ammonia) and such.
I would make the point that while we can speculate on tools to put in the tool box, it will be human motivation, and practicality that color the sequence and magnitude of the use of tools.
Economics will be one of the motivate humans, technical difficulties would on the other hand limit from a practical view what could be tried.
Actual hardware, and human culture, what people are motivated to do, what seems intelligent, or not worth it can change by the time these things are implemented.
A more certain inventory of resources available would color the decisions on how to do the teraforming.
Beginning with Lichen, I would say that it is likely that humans will be roughing it on Mars in small numbers at the time that Lichen would also be taking hold. Other than providing for their survival and comforts, if they have extra energy, they could begin releasing greenhouse gasses, and that if combined with a possible dumping of dust on the CO2 deposites on the south pole, just could be enough for an initial teraform to perhaps at least 11 mb.
Back to moisture. I have read that at 11 mb, the Mars climate could provide for true water snows, and I presume ice frosts across an expanded area. This is important for Lichen, because they do not need water in liquid form, but can do some amazing things just from moisture, snow, and ice.
http://www.antarctica.gov.au/about-anta … ts/lichens
Lichens have a number of adaptations that enable them to survive in Antarctica. They are able to exhibit net photosynthesis while frozen at temperatures as low as -20°C. They can absorb water from a saturated atmosphere when covered by snow. Additionally, snow cover affords protection from the elements and most growth appears to occur when they are buried beneath at least a thin protective layer of snow. They can survive long unfavorable periods of drought in a dry and inactive state. In continental Antarctica, many lichens are able to absorb water vapor from snow and ice.
So getting them covered with snow, and also prolonging the period of time they are surrounded by a water vapor saturated atmosphere, could only help them.
Further I hope that snow may be able to scrub the Chlorine out of the atmosphere, and so perhaps permit an accumulation of Ozone, also helping the Lichens.
Where it will likely turn out that there could be 100-1000 mb eventually available for atmosphere eventually, that is not certain, and also it may take quite some time to warm up the deep sub-surface to release it.
Specifically targeting the CO2 in the south pole while also releasing greenhouse gasses, is possibly the best way to move Mars to a condition where temporary water can run.
It is said that at 11 mb temporary streams could form from snow melts. In the best conditions, humans could then build infrastructure to capture those snow melts in some cases.
Then if they built up their capabilities they could build mirrors of the types we have suggested, or distribute dust to more than the South Pole, make it blackened dust if they could. They could intercept comets, or otherwise import Ammonia or whatever was in their capabilities.
I brought up the water splitting option because apparently it happened early in the history of Mars, and also it is a producer of Oxygen. Here again, if you wait for Lichens to provide Oxygen, then you have a long wait. But as this idea is saleable to some degree, it is possible that it will provide help earlier.
If somehow the CO2 expected was not actually available then their is an option. If it works very well, then maybe you don't want to prohibit condensation of CO2 at the poles, but store it there and release to the biosphere in a controlled manner, at a rate the biosphere can convert to O2.
Even if you opt for a 100-1000 mb atmosphere of dominantly CO2, (If the CO2 is availible), you might want to sweeten the atmosphere with Oxygen for plants early, because many plants use Oxygen at night.
But my main argument is that if you have tools, and I have tools they can be considered, and it it seems that they might have a use then they should go into a set of options, a tool box.
What tools are used and when and what sequence will depend upon a very large set of variables.
Nice Maps.
I would like to think about taraforming Mars again.
From what I think I know, an initial terraform process would likely be very similar to the popular ideas of the minds of this web site.
While there may be more resources for atmospheric inflation than the conservative value I will use, the conservative value is a good starting point. That value based on CO2 thought to be frozen into the southern ice cap is presumed to be enough to raise the average surface pressure to 11 mb. Methods to evaporate that CO2 ice include greenhouse gasses, and super greenhouse gasses as the most popular of the practical methods. However another relatively simple method to augment that is to scatter dirt from a Martian moon onto the surfaces where evaporation is desired.
So, at 11 mb, it supposed to be possible for the Martian climate to support actual water snow. I presume radiation protection would be improved, and based of tests of Lichens in simulations of the present Martian climate, Lichens, and Cyanobacteria could live in various locations, but biologically they would not be of that much significance, certainly not anywhere at the level of Earths biosphere. I am willing to admit that with such altered conditions the vapor/condensation process in the atmosphere might then scrub the Chlorine out of the atmosphere an make a partial Ozone layer occur.
I have read that it is now thought that Mars had an Oxygen ladened atmosphere early in it's history, not because of biology but from the splitting of H20 to it's components, and the loss of Hydrogen to the solar wind from the upper atmosphere of Mars.
I suggest that the second step in Taraforming Mars would be to replicate that process. It might be possible to shoot chunks of ice into the very tenuous upper atmosphere of Mars, and expect that they would evaporate into water vapor and the UV would split some if it. It might also be possible to divert small comets, and perhaps by some method break them up before impact, to inject water vapor into the upper atmosphere of Mars, but I am thinking about putting a double mirror system into the L1 location of Mars. (Between Mars and the Sun).
While it will tend to block light at the lower latitudes, with a slight tilt of the secondary mirror, it's output could be pointed at either polar ice deposit when they are in their summer seasons. The best focus could be tuned for the upper atmosphere, and after the focus, the concentration would still be very intense. I am expecting that in those conditions, water vapor would evaporate from the polar cap being targeted, and would rise up very high into the atmospheric column. At the focus, not only intense heat, but a concentration of UV should split some of the H2O, and being at a very low pressure at that altitude, recombination into water vapor would be discouraged, but some would, but also it could be expected that due to the presence of some C02, and N2, other compounds would occur. But the primary purpose would be to generate free Oxygen into the atmosphere of Mars. I know one person on the site might not like that, wasting Hydrogen to space, but I suggest that over time, directing small comets to the atmosphere of Mars would replenish the water reservoir of Mars, so that really only the population of comets would be diminished.
Bringing the pressure to 50 mb with an Oxygen dominated atmosphere, might make it possible for some types of insects to be involved with the biosphere, but they would have to be able to borrow into the soil to survive the very cold nights.
And of course the objective would be to bring the pressure and Oxygen content up to a level to not require as much or any life support gear to work on the surface of Mars, where and when the weather conditions permitted it.
I am thinking that the present CO2 reservoir might not be that toxic if diluted with Oxygen to that extent. In those conditions, the CO2 would serve as a greenhouse gas.
The payday on this would be the value of the Real Estate, improving it from a Human point of view.
So this would be stage 1 taraforming by processes well reviewed at this site, and stage 2, using a mirror justified by a large reward, where the planet would be improved for human use progressively.

A final issue would be Nitrogen. Perhaps Nitrogen will be recovered from Nitrate beds as some have suggested, or be brought in from off world, but without that, I have read that many plants would not do well with the Nitrogen levels presently occurring on Mars. Perhaps they can be engineered to cope with it. Some already probably can. But with a 250-300 mb atmosphere, depending on the level of greenhouse gasses, I would expect many ice covered bodies of water, and suggest that without any other success in the matter of Nitrogen, Nitrogen could be injected into the waters of those lakes, to provide at least an aquatic habitat for vegetation sensitive to a lack of Nitrogen.
I know that there is a lot of resistance to the dry valley lakes idea, but at any rate, I thought I would include it as an option.
At least my focus is on Mars, if you don't otherwise like any of the above.
Ok, I see your points. Low tech would be to have a swimming pool, and be able to do a lot of your work with voice commands to computers. Also a wheel chair to get around the house a lot of the time. Then as suggested machines to reduce the load on your body when you did serious walking.
Also if you were already a cyborg, perhaps you would just change out your legs to suit the task. But you would need some pretty good surface to orbit lifting method to get off the planet.
Low odds also but more favorable might be to find that Gliese 832 b (Gas Giant) had a moon system that was a Hybrid of Jupiter and Saturn.
A moon Like Titan with a nitrogen based atmosphere, and tidal heating from a partner moon. Perhaps shielding for the moons from Red Dwarf flares with the magentic field of the gas giant. But that's poor odds.
As for 832 c, I think 1.7 gees is quite a lot. Life could be there, but transplanting humans there would mean that to adapt they could have to have quite a lot of humanoid. Maybe short legs, and ape like mobility, or also amphibious behaviors, letting waters boyancy compensate for the large gravity.
Humanoid.
It also could be like Venus, or like Venus with a Hydrogen additive floating at the top of the Atmosphere, or if it does not have a sufficient magentic field, it's atmosphere could have been stripped away, since Red Dwafs tend to do that to their planet in the habitible zone (It is thought).
I see that the orbit is eliptical. To me that means it could be resonating with another planet. If if is the gas giant already mentioned, then their may be no other planets. If another planet is inside the habitible zone, then that third planet would be unfavored for terraforming.
However if their is a planet of reasonable size outside of the habitible zone, but between the gas giant and the super earth found, then perhaps if it is of reasonable size, it might have potential.
Resonation (Tidal heating) could make it more attractive. If it has retained a thicker atmosphere than 1 bar, (but not too thick), it might be suitable for liquid water, or at least possible to warm up.
But I guess there is some chance the super Earth identified might be "Habitible" so I will add this link which speaks of super Earths and continents.

I wonder what the gravity would be like on that world if it does have solid ground?
I have been considering Urea, to enhance photo-biological processes, and as a sideline to recycle potentially infectious output from humans.
Most ice needed for biological processes on Mars would be obtainable at higher latitudes, and solar energy and temperatures are not too unfavorable
at Mid Latitudes. So I am imagining placement of the machine in the "Temperate" zones of Mars where buried ice is significantly available.
As a minimum habitat for photo-cyanobacteria, I suggest a "Tent" where in the case of the Northern Hemisphere, a north vertical wall is reflective on
it's south side, and a UV tolerant flexible transparent/translucent sheet is attached to the top of that wall, and projects at an angle down to the ground forming a solar
tent where it's interior is not pressurized, and also is warmer than the normal environment because of the reflection of extra light onto the horizontal
surface of the ground it encloses. Also that interior will have a reduced UV flux.
This is to protect a number of somewhat pressurized transparent bladders intended to retain a content of liquid water, with a additional additive of
Urea.
The bladders can be in trenches or just lay on the ground.
The purpose of the Urea, is to serve as a relatively mild antifreeze, and to provide fertility to Photo-Cyano bacteria, or other organisms which
humans might want to promote the growth of.
With the tenting and concentration of light, and the urea anti-freeze, and the fact that water has thermal inertia, I am hoping that a urea tolerant
extreme Photo-Organism could thrive, producing biological materials of use to a human presence on Mars.
I propose that most urea in use would be manufactured, and likely therefore not a path for infection.
For the disposal of human urine and the eventual recycling of the water of it, I propose a separate process otherwise identical. This is for hygiene,
as it is unwise and repugnant to have human waste products be too tightly tied to human ingestion of food and water.
So the process using nonhuman urea could provide bio fuels, and perhaps even some types of foods. The bio-fuels could provide feedstock for plastics
production.
The parallel processes which used human urine would be restricted to produce bio-fuels, and plastics.
The recycling of water would likely be by boiling/evaporation from the bladders when the daytime energy input favored it. Water from human waste
would not be used (Except in emergencies) for ingestion.
Water from the nonhuman involved process would be used for any purpose.
