Colonizing Mars

Recently, Elon Musk threw a Tesla car at Mars and somewhat carelessly, missed. How can you miss a planet? The answer is, not unsurprisingly, quite easily. Mars might be a planet, and planets might seem large, but they are staggeringly small compared with the solar system. But whatever else this achieved, it did draw attention back to thoughts of humans on Mars, and as an exercise, it is not simple to bring the two together. Stephen Hawking was keen on establishing a colony there, mainly as some sort of reserve for humanity in case we did something stupid with out own planet. Would we do that? Unfortunately, the answer is depressingly quite possibly.

So what is required to get to Mars? First, not missing. NASA has shown that it can do this, so in principle this problem is solved. The second requirement is to arrive at the surface at essentially zero vertical velocity, and NASA has not been quite so successful at that, nevertheless, we can assume that landing will be with a piloted shuttle, so this should be able to be done. So far, so good? Well, not quite, because when you get there you have to have enough “stuff” to ensure you can survive. If it is a scientific exploration, the people will be away for over two years, so at a minimum, they will need groceries for two years, unless they grow their own food. They will need their own oxygen and water unless they can recycle it. They will need some means of getting around or there is no point in going, and they will need some sort of habitat. If they are settlers they will need a lot more because they are not coming back.

The obvious first thing to for settlers to do is to have somewhere to live. We can assume that the ship that brought them will provide a temporary place, although if the ship is to be recycled back to earth and they came down in a shuttle, this is a priority. At the same time they must build facilities to grow their own food and make oxygen. This raises the question, how many people could actually grow food and guarantee to do it well enough not to starve in a totally different environment to here? I am not sure you can train for that, but even if you can, there will still need to be a lot of food taken as well as oxygen. However, let’s assume these settlers are really competent and they are raring to get on with it.

The first requirement would be enough area to do it, so they would need a giant glass house (or houses). That means glass, and metal to hold it, but there is worse. You have to pressurize it, because the Martian atmospheric pressure on average is only about ½% of Earth’s. That means you need a strong pump, but because of the aggressive nature of dust in the atmosphere much of the time, you need some form of filter. The air is about 95.3% carbon dioxide, about 2.7% nitrogen and 1.6% argon. If you want to recover the oxygen to breathe, you want to boost the nitrogen so that what is produced is breathable as air, and that requires a major gas separator. The best way is probably to seriously overpressurise it, so the carbon dioxide comes out as a liquid, and keep the rest. However, there is another problem: you need water, so that equipment will probably have to be made even more complicated so the water in the atmosphere can be recovered. The next problem is that if the glasshouse is to be pressurized, it has to be leak-proof. All the joints have to be sealed with something that will not decay under UV radiation, and worse than that, a deep footer is needed around the glasshouse. That means digging a deep trench, pouring concrete, and sealing the walls. Finally, the whole regolith inside the glasshouse has to be treated to decompose its strong oxidizing nature (but this does produce a small amount of oxygen) otherwise the soil will sterilize anything you plant, then you have to add some actual soil. Many of these operations would be best done mechanically, but they each need their own machine.

You may notice that all of these things costs weight, and that is not what is wanted on a space ship. So the question is, how much can be brought there? There is a second requirement. Every time you use a machine, you need fuel. That has to be electric, which means either batteries, which so far would require huge numbers to keep going all day, or fuel cells, but if fuel cells are selected, what will be the fuel? Note that two fuels are required; one to “burn” and the other to burn it in, as there is no oxygen in the atmosphere worth having. Either way, a serious energy producer is required because not only do you have to power things, but you have to keep your glasshouse warm. The night-time temperatures can drop below minus 100 degrees Centigrade. The most obvious source is nuclear, either fission or fusion, but that requires shielding and even more weight.

The above is just some of the issues. I wrote a novel (Red Gold) that involved Martian settlement. The weight of the two ships was twenty million tonne each, and each had a thermonuclear propulsion system that detached and could be used as power plants and mineral separation units later. The idea was that construction materials would be made there, but even if that is done, a huge amount of stuff has to be taken. Think of the cost of lifting forty million tonne of stuff from Earth into orbit alone. Why two ships? Because everything should be done in duplicate, in case something goes wrong. Why that much stuff? Because you want this not to be some horrible exercise in survival.

At this stage I shall insert a small commercial. Red Gold is a story of such colonization, and of fraud, and it includes a lot more about what it might take to colonize Mars. It is available on Kindle Countdown discounts from 13 – 19 April. (

The Trump Enigma

That would make a great book title, in the “truth is stranger than fiction” genre. Right from the get-go, Trump’s Presidential campaign was totally puzzling: he never seemed to miss insulting just about every minority you could think of; he ran around making grandiose statements that were either hideously ridiculous, such as Mexico was going to build his wall, or he was saying things that everyone seemed to recognize readily as being very unlikely to be correct. It was not as if he were trying to fool everybody; he looked the exact opposite of a con man. He was ramming statements in people’s faces in a way that almost challenged them not to believe. How could anybody win like that?

He did have some statements that almost certainly struck home. “Drain the swamp!” was one such statement. All around the world there are a lot of people who have little faith in politicians, and many people are convinced that politicians specially favour big business, etc. We also see politicians closing down the government for no good reason other than petty politics, or pushing extraneous agendas. So that sort of statement should have struck oil.

However, recently I came across a news extract that summarized parts of Michael Wolff’s Fire and Fury, and here was a surprising explanation: Trump did not want to be President. He wanted to lose. As the campaign was coming to an end, he was about 10 points behind. That did not bother him. Trump intended to run a TV network, and his aim was to be one of the most famous men in the world. He was happy. He did not want to be President, and just about everyone close to him thought he should not be. Trump apparently said something like he was not thinking about losing because he wasn’t going to lose. He would not be President, but he would be a huge winner.

Why did he not release his tax returns? Because it never occurred to him he would win, and if he lost, there would be no point. He had a built-in whinge against Preibus, the Chairman of the Republican National Committee, hence an excuse for losing. He would be a martyr to “Crooked Hillary”. His family would be extremely famous. Kellyanne Conway could be a cable news star. Then a wheel fell off. Comey made his famous public statement and Hillary’s ratings started to fall. Apparently, on the night the results came in, Melanie burst into tears at the news. Trump did not believe it, then he became horrified, then suddenly he decided, yes, he could do this.

I have no idea how accurate this is, but this is what Michael Wolff apparently wrote. My initial thought after reading this was, Dang! Why couldn’t I have thought of something like this sooner? This would make a great plot for a novel, and it’s wasted, thanks to Trump.

But this puts a new perspective on Robert Mueller’s investigation into Russian collusion. There cannot be collusion between two parties unless they have a common objective. If the Russian interventions, if there were such interventions, were aimed at promoting Trump, as is usually asserted, and Trump was trying to lose, there can be no collusion. On the other hand, suppose the Russian interventions were aimed at getting Trump to lose, can you collude and plot to lose? Or will the proposed collusion now make Hillary guilty, because she was the only possible beneficiary? Or was such Russian activity a clever punishment on Trump? Or, as I feel is more likely, if some Russians did something, it was totally independent and not coordinated with Trump or his campaign. Who knows?

Yet, in a way, this forks Trump. Now he is President, can he really afford to announce that he tried to lose? Can he make that his defence against Mueller’s probe? To add to the mix, right now there is a memo that Congress wants to release that some people claim relates to the Christopher Steele report, which is the basis of the allegations of collusion. Now Steele runs a consulting company and was an MI6 agent, and the funding for this report apparently came from the Clinton/Democrat party. Is that not collusion with a foreign agent to undermine the US political process? Is there any way out of this mess for anyone?

All the same, I wish I had thought of that plot. Not, of course, that anyone would have believed it to be plausible. It would be laughed out of court as to ridiculous for words.

That Was 2017, That Was

With 2017 coming to a close, I can’t resist the urge to look back and see what happened from my point of view. I had plenty of time to contemplate because the first seven months were largely spent getting over various surgery. I had thought the recovery periods would be good for creativity. With nothing else to do, I could write and advance some of my theoretical work, but it did not work but like that. What I found was that painkillers also seemed to kill originality. However, I did manage one e-novel through the year (The Manganese Dilemma), which is about hacking, Russians and espionage. That was obviously initially inspired by the claims of Russian hacking in the Trump election, but I left that alone. It was clearly better to invent my own scenario than to go down that turgid path. Even though that is designed essentially as just a thriller, I did manage to insert a little scientific thinking into the background, and hopefully the interested potential reader will guess that from the “manganese” in the title.

On the space front, I am sort of pleased to report that there was nothing that contradicted my theory of planetary formation found in the literature, but of course that may be because there is a certain plasticity in it. The information on Pluto, apart from the images and the signs of geological action, were well in accord with what I had written, but that is not exactly a triumph because apart from those images, there was surprisingly little new information. Some of which might have previously been considered “probable” was confirmed, and details added, but that was all. The number of planets around TRAPPIST 1 was a little surprising, and there is limited evidence that some of them are indeed rocky. The theory I expounded would not predict that many, however the theory depended on temperatures, and for simplicity and generality, it considered the star as a point. That will work for system like ours, where the gravitational heating is the major source of heat during primary stellar accretion, and radiation for the star is most likely to be scattered by the intervening gas. Thus closer to our star than Mercury, much of the material, and even silicates, had reached temperatures where it formed a gas. That would not happen around a red dwarf because the gravitational heating necessary to do that is very near the surface of the star (because there is so much less falling more slowly into a far smaller gravitational field) so now the heat from the star becomes more relevant. My guess is the outer rocky planets here are made the same way our asteroids were, but with lower orbital velocities and slower infall, there was more time for them to grow, which is why they are bigger. The inner ones may even have formed closer to the star, and then moved out due to tidal interactions.

The more interesting question for me is, do any of these rocky planets in the habitable zone have an atmosphere? If so, what are the gases? I am reasonably certain I am not the only one waiting to get clues on this.

On another personal level, as some might know, I have published an ebook (Guidance Waves) that offers an alternative interpretation of quantum mechanics that, like de Broglie and Bohm, assumes there is a wave, but there are two major differences, one of which is that the wave transmits energy (which is what all other waves do). The wave still reflects probability, because energy density is proportional to mass density, but it is not the cause. The advantage of this is that for the stationary state, such as in molecules, that the wave transmits energy means the bond properties of molecules should be able to be represented as stationary waves, and this greatly simplifies the calculations. The good news is, I have made what I consider good progress on expanding the concept to more complicated molecules than outlined in Guidance Waves and I expect to archive this sometime next year.

Apart from that, my view of the world scene has not got more optimistic. The US seems determined to try to tear itself apart, at least politically. ISIS has had severe defeats, which is good, but the political futures of the mid-east still remains unclear, and there is still plenty of room for that part of the world to fracture itself again. As far as global warming goes, the politicians have set ambitious goals for 2050, but have done nothing significant up to the end of 2017. A thirty-year target is silly, because it leaves the politicians with twenty years to do nothing, and then it would be too late anyway.

So this will be my last post for 2017, and because this is approaching the holiday season in New Zealand, I shall have a small holiday, and resume half-way through January. In the meantime, I wish all my readers a very Merry Christmas, and a prosperous and healthy 2018.

Where to settle on Mars?

A few weeks ago I wrote an introductory post on Martian settlement issues ( ). I am now going to ask, where should such a settlement be? Obviously, this is a matter of opinion, but there are some facts to consider. The first is seasons. The northern hemisphere spring and summer is about 75 Martian days longer than the autumn and winter (and opposite for the southern hemisphere. This is a consequence of the elliptical orbit, but it also means that the longer seasons mean the planet is further from the sun (which is why it is going slower) and because of the axial tilt that generates the seasons as well as the elliptical orbit, most likely places can get up to 40% less sunlight in winter than in summer. Add to that that by being so much further from the sun, Mars never gets more than about half the Earth’s solar energy. So the southern hemisphere has a shorter but warmer pair of seasons, and a longer colder other pair. Temperatures in summer can get up to 20 degrees C in the day and in winter, fall to minus 120 degrees C during the night. No plant can survive that, so besides providing air, heat is also required.

There is a reasonably easy way to get around the heat problem. Assuming you have a nearby power plant, and as I shall show in other posts, if a settlement is to be viable, it will have a heavy demand for high quality energy, then there will inevitably be waste heat. Space mirrors can also supplement the heat and light. Heating the planet is not on (you would need mirrors of area greater than the Martian cross-sectional area) but heating a settlement is plausible.

The location could be decided on the basis of nearness to raw materials, but that leaves open the question of which ones? The obvious one is metal ores, but here we do not know where they are, of even if they are. Again this can be left for another post.

The next question is air. Air pressure depends on altitude, and much of the exploration so far has been around the zero of altitude, where we get pressures of around 6 -8 millibar, depending on the season. In the southern hemisphere summer, the pole shrinks and vaporizes a lot of carbon dioxide, thus increasing atmospheric pressure. In my novel Red Gold I put the initial settlement at the bottom of Hellas Planitia. That is in the southern hemisphere, and is a giant impact crater, the bottom of which is about nine kilometres deep. That gives more atmospheric pressure, but at the cost of a cold winter. The important point of Hellas Planitia is that at the bottom of the impact crater the pressure, is high enough to be the only place on Mars for liquid water to exist, particularly in summer. The reason this was important, at least in my novel, is that unless you find water, you will probably have to pump it from the atmosphere and condense it. Also, while you are pumping up domes, you will want to get the dust out of the air. The dust is extremely fine. That means very fine filters, which easily clog; electrostatic dust precipitators, which may be too slow for many uses; or a form of water filtration. In Red Gold, I opted for a water-ring type pump. Of course here you need a certain amount of water to get started, and that will not be a small amount. The water will still evaporate fairly quickly, hence the need to have plenty of water, but the evaporite will go into the dome, so it is recoverable or usable. It could also be frozen out before going in; whatever else is in short supply on Mars, cold is not one of them, although with the low atmospheric pressure, the heat capacity of air is fairly low.

So strictly speaking, based on heat and air, both have to be heavily supplemented, it does not matter where you go. However, I think there is another good reason for selecting Hellas Planitia as the site. It is generally considered that water, or at least a fluid, flowed on Mars. The lower parts of Hellas have signs that there was water there once, and to the east two great channels, the Dao and the Harmarkis, seemingly emptied themselves into the Hellas basin. Water will flow downhill, so a lot of it would have resided in depressions, and either evaporated, or solidified, or both. So, there is a good chance that there is water there, or anything that got dissolved in the water. The higher air pressure will also help reduce sublimation by a little bit, so perhaps there will be more there than most places.

The next issue is, you wish to grow food and have plants make oxygen. Obviously you will need some fairly sophisticated equipment to get the oxygen from the plants to wherever you are going to live, assuming you don’t live with the plants, but the plants have to grow first. For that you need soil, water and fertilizer. The soil is the first problem. It is highly oxidised, and chlorides have been oxidised to perchlorates. That is fine for making a little oxygen, but it has to be treated or it will kill plants. Apparently it is something as good as bleaching powder. Again, you will have to take the treatment chemicals with you; forget something critical or do not bring enough, and you will be dead. Mars is not a forgiving place.

That leaves fertilizer. Most rock has some potassium and phosphate in it, and if these have been washed out, their residues will be where the water ended, so that should be no problem if you go to the right place. Nitrogen is slightly different. The atmosphere has very little nitrogen. On Earth, plants get their nitrogen from nitrates washed down in rain, from decayed biomass, and from farmers applying it. None of that works there immediately. Legumes can “fix” nitrogen from the air, but there isn’t much there to fix and partial pressure is important. You can, of course, pump it up and get rid of carbon dioxide. A lot of these issues were in the background of my ebook novel Red Gold, ad there, I proposed that Mars originally had somewhat more nitrogen, but it ended up underground. The reason is for another post, but the reason I had then ended up as being the start of my theory regarding planetary formation. However, the possibility of what was leached out or condensed out being at the bottom of the crater is why I think Hellas Planitia is as good a place as any to start a settlement.

Quick Commercial: Red Gold will be discounted to 99 c for six days starting the 13th. It is basically about fraud, late 1980s style, but much of the details of settling Mars are there.

UK Election Fallout and Qatar: what would you do if in charge?

Suppose like me you are an author of fiction. Given the following situations, put yourself in someone’s shoes and ask yourself, what next?

The first event was the rather unfortunate end result of the UK election. What was delivered was what I consider to be the worst possible outcome. The problem is, voters are sucked in by “jam today”, or “I am annoyed about something.” So, what now? First, some background. The national debt of Britain now stands at £ 1.73 trillion, and the interest payment on this debt is about 6% of revenue. That might seem to be reasonably sustainable, but there is the overall issue of Brexit looming. The UK has apparently had a recent surge in GDP, despite the threat of Brexit, but it is not clear that will last, and interest rates will probably grow from their record low. Suppose they double, which is easy from such lows. 6% suddenly turns to 12%, and that is ugly. (The existing loans will stay at their agreed rate, but can you pay them back when they mature? Otherwise you have to borrow at the new rate.) It appears that Jeremy Corbyn was promising a lot of spending, together with an unspecified increase in taxes. My guess is a lot of the youth vote that went to Corbyn thought the rich would pay. The usual problem with that assessment is that while the rich can be made to pay significantly higher taxes, to get the amounts needed to make a significant difference in revenue tax rises have to go a lot deeper. There are just not enough rich to soak. On the other hand, people may well argue they needed more money to go to health, education, or whatever. The question then is, can you pay for what you want?

May was apparently promising austerity. That is hardly attractive, but it was also put forward in a rather clumsy way. Cutting out school lunches is not only hardly a vote winner, but it is also never going to make a huge difference. Putting that up front is a strange way to win an election. It seems that the Tories were so convinced they were going to win that they decided to put up some policies that they knew would be unpopular, so they could say later, “You voted for them.” The two who are believed to have largely written the manifesto have resigned (really, pushed by angry senior Tories) but the question remains, why were they left to write it? Why did the senior Cabinet Ministers not know what was in it, or if they knew, why did they not do something about it? There’s plenty of blame to go around here, folks, nevertheless there are two hard facts: if Britain and the EU cannot manage Brexit properly, there will be severe economic problems, and economic problems seem to be like a very active virus that goes everywhere very quickly. The second is, if debt gets out of hand, the country spends so much on interest repayments that it ends up in the position Greece is now in. Anyone want that?

So, put yourself in some position: what would you do? My opinion is the Tories should realize that Corbyn has no chance currently of forming a government (because he needs every non-Tory vote) and get on doing something that has at least some public appeal. May either has to go, or learn oratory and get some empathy for the others.

The other event is the Arab attempt at isolating Qatar, on the grounds it is financing terrorism. Actually, the Saudis are almost certainly the biggest such supporters. The real reason appears to be either Qatar is friendly with Iran, or alternatively Qatar is the home of al Jazeera, a TV network that tries by and large to report the facts, warts and all. The US position on this is obscure. President Trump has lashed out against Qatar, without any particular evidence, although Qatar is known to have given refuge a number of Egypt’s Muslim Brotherhood. The US is also bombing Assad’s troops in Syria to prevent them getting at fleeing ISIS fighters; it seems that terrorism is being actively supported by the US, which make no strategic sense. At first, it looks as if Qatar could be quickly invaded from Saudi Arabia, but whoever does that would have to be very careful because Qatar houses the biggest local US base in the region, and has 11,000 military personnel there. To add to the complications, Turkey has promised to send troops. Fighting Turkey should mean fighting NATO, although with President Trump nothing automatically follows.

So, imagine you are the leader of Qatar, what would you do? Return the Muslim Brotherhood members to Egypt where they would probably be tortured and/or executed? Promise to stop funding terrorists? (If you really are not, this is easy to keep, but maybe not so easy to convince others that you are keeping it.) Remember, whatever you decide to do, you have to be prepared for whatever consequences follow. Not easy working out what leaders should do, is it? Writing fiction is, of course, easier, because you control what happens next. But if you want that fiction to have some relation with reality, what happens next has to be plausible, so here is your chance to get some practice.
