Poul Anderson and Ideas about Terraforming Venus Before Carl Sagan

December 21, 2022

This might appeal to readers of this blog, who aren’t fans of the late astronomer, Sceptic and presenter of the blockbusting TV science series, Cosmos. I put up a drawing I’d done of Sagan a week or so ago along with a piece explaining why I thought he was a great TV personality. While Sagan was a brilliant astronomer and space scientist, some of the readers of this blog were less impressed by his attitude towards the UFO crowd. Sagan was a fervent rationalist, who saw it as his mission to attack ideas he thought were irrational, and particularly the paranormal. He was one of the founders of the Sceptical organisation, CSICOP, or the Committee for the Scientific Investigation of Claims of the Paranormal, along with the stage magician James Randi and the mathematician Martin Gardner. One of Sagan’s last works was The Demon-Haunted World in which he worried about the tide of irrationality creeping over America and the world and foresaw a time in which the New Age would have taken over completely, leading to a new Dark Age and people earnestly consulting their horoscopes each morning.

Some commenters remembered how Sagan had been wheeled on TV in the 1960s to debunk UFO encounters. They didn’t like his superior and condescending attitude towards the experiencers. Now I’ll admit that I don’t regard UFOs as nuts and bolts alien spacecraft. Much of the imagery and the basic plot of UFO encounters seems to come from science fiction and supernatural encounters with gods, demons and fairies before then. One of the alternative views of the UFO phenomenon is the psycho-social hypothesis, which sees it as an internal psychological experience which uses the imagery of contemporary culture. In previous centuries this was of fairies. Now, as belief in the supernatural has declined in the West, the imagery is from science fiction. But both the imagery of fairies and alien spacecraft represent the same theme of encounter with a cosmic other. Some UFO writers and researchers like John Keel and Jacques Vallee believe that there is a genuine paranormal phenomenon at work, and that the force that was previously responsible for encounters with fairies and so on has simply now changed to using that of space craft as society has changed. See Keel’s Operation Trojan Horse, for example. Many UFO encounters can be explained as misidentification, hoaxes, and sightings of top secret military aircraft. I’m also convinced that some are due to the intelligence community deliberately messing with people for their own purposes. In one of his books, Vallee suggests that the Cergy-Pontoise abduction in France may have been faked by French intelligence as an experiment to see how people would react to a real alien encounter. And then there’s the case of Paul Bennewitz, a defence contractor in the US who was driven out of his mind by a pair of intelligence agents at a nearby USAF base. Bennewitz thought he had got in touch with an alien held captive at the base. The pair claimed to be whistleblowers and fed Bennewitz a whole load of spurious documents apparently confirming it, and then told him that it was all fake. It’s a tactic apparently known as the ‘double-bubble’ used by the intelligence services to destabilise their enemies. It worked on Bennewitz, who I think was driven to a nervous breakdown.

Even with the hoaxers, the top secret aircraft and the misidentified objects, there are still some UFO encounters that are very difficult to explain. I think the best explanations are probably the paranormal and psycho-social rather than the Extra-Terrestrial Hypothesis. But that doesn’t necessarily mean that they’re any the less puzzling nor that genuine people, who have had a truly inexplicable experience, should be sneered or condescended to.

But back to Sagan. One of Sagan’s achievements was to suggest a way Venus could be terraformed. This involved planting genetically-engineered bacteria in the Venusian atmosphere. These would consume the carbon dioxide and exhale breathable oxygen. But Sagan wasn’t the first person to suggest ways of terraforming the planet, and he didn’t invent the concept of terraforming. You can find the idea, but not the name, in the Martian books of Edgar Rice Burroughs, in which the Martians have built giant machines to replenish the atmosphere on their dying world. The great SF writer Poul Anderson wrote a story in which a similar technology is used to terraform the Venusian atmosphere.

This is mentioned by Mike Ashley, the editor of the anthology of classic SF stories about the worlds of the solar system, Born of the Sun, published by the British Library. In the introduction to the story about Venus, Ashley writes

‘The 1950s saw some authors taking note of recent research which suggested Venus was far from a watery world. Leading the way was Poul Anderson. In ‘The Big Rain’ (1954) he describes a harsh, sweltering Venus that, when it does rain, rains formaldehyde. The story considers how Venus might be terraformed, using the formaldehyde locked in Venus’ clouds. Airmaker machines, spread all over Venus, accelerate a reaction with the formaldehyde, ammonia and methane to produce hydrocarbons and oxygen, whilst bombs reinvigorate volcanos so that in time it starts to rain – and rains for over a hundred years, by which time Venus starts to be more Earth–like’. (p. 93).

To me, this is an example of one the instances where informed Science Fiction, even if wrong in the details, has advanced scientific thinking. And there are plenty of other examples in some of the other stories Ashley discusses in some of the other books in the same series.

Sagan, for all his faults, was a brilliant scientist and he did much to make people aware of the environmental crisis and opposed the threat of nuclear war and the New Cold War Reagan and Thatcher started ramping up in the 1980s. But in this case, while his ideas about terraforming Venus are most likely to be correct, he wasn’t the first to invent the idea.

Sometimes SF writers get there first.

The Operation of Worker-Owned Companies in Martian SF

December 9, 2018

A week or so ago I put up a few passages from Kim Stanley Robinson’s Blue Mars (London: HarperCollins 1996), a science fiction book about the colonization and terraformation of the Red Planet. In Robinson’s book, on breaking away from terrestrial domination the Martians establish a constitution which makes all the companies not owned by the global Martian state or its constituent cities worker-owned cooperatives, partly modelled on the Mondragon cooperatives in Spain. On page 301 Robinson describes how Nadia, the new Martian president in the capital, Sheffield, works to transform the planet’s industries, including those formerly owned by terrestrial metanats – vast multinationals that now dominate the industries of whole countries – into the new system. Robinson writes

Nadia, however, never made it to this conference. She got caught up by affairs in Sheffield instead, mostly instituting the new economic system, which she thought important enough to keep her there. The legislature was passing the law of eco-economics, fleshing out the bones drawn up in the constitution. They directed co-ops that had existed before the revolution to help the newly independent metanat local subsidiaries to transform themselves into similar co-operative organisations. This process, called horizontalization, had very wide support, especially from the young natives, and so it was proceeding fairly smoothly. Every Martian business now had to be owned by its employees only. No co-op could exceed one thousand people; larger enterprises had to be made of co-op associations, working together. For their internal structures most of the firms chose variants of the Bogdanovist models, which themselves were based on the co-operative Basque community of Mondragon, Spain. In these firms all employees were co-owners, and they bought into their positions by paying the equivalent of about a year’s wages to the firms equity fund. This became the starter of their share in the firm, which grew every year they stayed, until it was given back to them as pension or departure payment. Councils elected from the work-force hired management, usually from outside, and this management then had the power to make executive decisions, but was subject to a yearly review by the councils. Credit and capital were obtained from central co-operative banks, or the global government’s start-up fund, or helper organisations such as Praxis and the Swiss. On the next level up, co-ops in the same industries or services wer associating for larger projects, and also sending representatives to industry guilds, which established professional practice boards, arbitration and mediation centres, and trade associations.

I can’t say I’m happy about the idea of worker managers buying their share of management with the equivalent of a year’s pay. This seems far too easy for someone to exploit to me. And I’m also not sure how practical it would be to turn all companies into co-operatives. However, we do need industrial democracy, if only to overturn the massive exploitation of working people that has gone on under Thatcherism. Under the current Thatcherite orthodoxy, wages are frozen, jobs insecure and the welfare system undermined and destroyed. A quarter of a million people have been forced to use foodbanks to save themselves from starvation, and 330,000-odd people are homeless. And the number of people dying on our streets, and the elderly in their homes due to Tory cuts in the cold weather payments, has shot up. And this has all been to give the rich tax cuts and provide employers with a cheap, cowed workforce.

Enough’s enough. We need a proper government with a proper vision that treats working people decently, with proper wages and rights at work, invigorates trade unions, restores a strong and health welfare state, builds properly affordable homes and reverses the privatization of the NHS. Only Corbyn’s Labour promises all that. And part of this promise is to put workers on the boards of all firms with over a certain number of employees.

Corbyn is the person we need to have in No.10. Not Tweezer and her gang of crooks and profiteers. Get them out, and Labour in.

An Argument for Industrial Democracy from the Mars of SF

November 5, 2018

I’m currently reading Blue Mars, the last of a trilogy of books about the future colonization of the Red Planet by Kim Stanley Robinson. Written in the 1990s, this book and the other two in the series, Red Mars and Green Mars, chronicle the history of humans on Mars from the landing of the First 100 c. 2020, through full-scale colonization and the development of Martian society to the new Martians’ struggle for independence from Earth. In this future, Earth is run by the metanats, a contraction of ‘metanational’. These are the ultimate development of multinational corporations, firms so powerful that they dominate and control whole nations, and are the real power behind the United Nations, which in theory rules Mars.

As the Martians fight off Terran rule, they also fight among themselves. The two main factions are the Reds and the Greens. The Reds are those, who wish to preserve Mars in as close to its pristine, un-terraformed condition as possible. The Greens are those on the other side, who wish to terraform and bring life to the planet. The Martians are also faced with the question about what type of society and economy they wish to create themselves. This question is a part of the other books in the series. One of the characters, Arkady Bogdanov, a Russian radical, is named after a real Russian revolutionary. As it develops, the economy of the free Martians is partly based on gift exchange, rather like the economies of some indigenous societies on Earth. And at a meeting held in the underground chamber of one of the Martian societies – there are a variety of different cultures and societies, reflecting the culture of various ethnic immigrant to Mars and the political orientation of different factions – the free Martians in the second book draw up their tentative plans for the new society they want to create. This includes the socialization of industry.

Near the beginning of Blue Mars, the Martians have chased the Terran forces off the planet, but they remain in control of the asteroid Clarke, the terminus for the space elevator allowing easier space transport between Earth and Mars. The Martians themselves are dangerously divided, and so to begin the unification of their forces against possible invasion, they hold a constitutional congress. In one of the numerous discussions and meetings, the issue of the socialization of industry is revisited. One member, Antar, is firmly against government interference in the economy. He is opposed by Vlad Taneev, a biologist and economist, who argues not just for socialization but for worker’s control.

‘Do you believe in democracy and self-rule as the fundamental values that government ought to encourage?’
‘Yes!’ Antar repeated, looking more and more annoyed.
‘Very well. If democracy and self-rule are the fundamentals, then why should people give up these rights when they enter their work place? In politics we fight like tigers for freedom of movement, choice of residence, choice of what work to pursue – control of our lives, in short. And then we wake up in the morning and go to work, and all those rights disappear. We no longer insist on them. And so for most of the day we return to feudalism. That is what capitalism is – a version of feudalism in which capital replaces land, and business leaders replace kings. But the hierarchy remains. And so we still hand over our lives’ labour, under duress, to fee rulers who do no real work.’
‘Business leaders work,’ Antar said sharply. ‘And they take the financial risks-‘
‘The so-called risk of the capitalist is merely one of the
privileges of capital.’
‘Management -‘
‘Yes, yes. Don’t interrupt me. Management is a real thing, a technical matter. But it can be controlled by labour just as well by capital. Capital itself is simply the useful residue of the work of past labourers, and it could belong to everyone as well as to a few. There is no reason why a tiny nobility should own the capital, and everyone else therefore be in service to them. There is no reason they should give us a living wage and take all the rest that we produce. No! The system called capitalist democracy was not really democratic at all. That’s why it was able to turn so quickly into the metanational system, in which democracy grew ever weaker and capitalism every stronger. In which one per cent of the population owned half of the wealth, and five per cent of the population owned ninety-five per cent of the wealth. History has shown which values were real in that system. And the sad thing is that the injustice and suffering caused by it were not at all necessary, in that the technical means have existed since the eighteenth century to provide the basics of life to all.
‘So. We must change. It is time. If self-rule is a fundamental value. If simple justice is a value, then they are values everywhere, including in the work place where we spend so much of our lives. That was what was said in point four of the Dorsa Brevia agreement. It says everyone’s work is their own, and the worth of it cannot be taken away. It says that the various modes of production belong to those who created them, and to the common good of the future generations. It says that the world is something we steward together. That is what it says. And in our years on Mars, we have developed an economic system that can keep all those promises. That has been our work these last fifty years. In the system we have developed, all economic enterprises are to be small co-operatives, owned by their workers and by no one else. They hire their management, or manage themselves. Industry guilds and co-op associations will form the larger structures necessary to regulate trade and the market, share capital, and create credit.’
Antar said scornfully, ‘These are nothing but ideas. It is utopianism and nothing more.’
‘Not at all.’ Again Vlad waved him away. ‘The system is based on models from Terran history, and its various parts have all been tested on both worlds, and have succeeded very well. You don’t know about this partly because you are ignorant, and partly because metanationalism itself steadfastly ignored and denied all alternatives to it. But most of our micro-economy has been in successful operation for centuries in the Mondragon region of Spain. the different parts of the macro-economy have been used in the pseudo-metanat Praxis, in Switzerland, in India’s state of Kerala, in Bhutan, in Bologna, Italy, and in many other places, including the Martian underground itself. These organization were the precursors to our economy, which will be democratic in a way capitalism never even tried to be.
(pp. 146-8).

It’s refreshing to see a Science Fiction character advocate a left-wing economics. Many SF writers, like Robert A. Heinlein, were right-wing. Heinlein’s The Moon Is A Harsh Mistress, about a rebellion on the Moon, contains several discussion in which Heinlein talks about TANSTAAFL – his acronym for There Ain’t No Such Thing As a Free Lunch.

Praxis is the fictional metanational corporation, which supplies aid to the colonists against the rest of the terrestrial super-corporations. I don’t know about the references to Switzerland, Kerala, Bhutan or Bologna, but the Mondragon co-operatives in Spain certainly exist, and are a significant part of the country’s economy. They were set up by a Spanish priest during Franco’s dictatorship, but managed to escape being closed down as he didn’t recognize such enterprises as socialist.

I don’t know how practical it would be to make all businesses co-operatives, as there are problems of scale. Roughly, the bigger an enterprise is, the more difficult proper industrial democracy becomes. But co-operatives can take over and transform ailing firms, as was shown in Argentina during the last depression there a few years ago, when many factories that were about to be closed were handed over to their workers instead. They managed to turn many of them around so that they started making a profit once again. Since then, most of them have been handed back to their management, however.

But the arguments the Vlad character makes about democracy being a fundamental value that needs to be incorporated into industry is one of that the advocates of industrial democracy and workers’ control, like the Guild Socialists, made. And we do need to give workers far more power in the work place. Jeremy Corbyn has promised this with his pledge to restore workers’ and union rights, and make a third of the directors on corporate boards over a certain size elected by the workers.

If Corbyn’s plans for industrial democracy in Britain become a reality, perhaps Britain really will have a proper economic system for the 21st century, rather than the Tories and Libertarians trying to drag us back to the unfettered capitalism of the 19th.

Rush Limbaugh: Evidence of Flowing Water on Mars Is Leftist NASA Plot

August 20, 2017

Here’s another right-wing gasbag, who should lose his radio show. In this clip from two years ago – 2015 – host Sam Seder of The Majority Report comments on Rush Limbaugh’s pronouncements about signs of flowing water on today’s Mars by NASA. NASA announced that they had found evidence that water still flows today on the Red Planet at the right season. The space agency states that this is a survivor from the period, 3 billion years ago, when the planet was much warmer and wetter than today, and a great ocean may have covered the entire northern hemisphere. The discovery is of immense importance in the search for possible life elsewhere in the solar system.

This is science, but it’s too much for Rush Limbaugh, who sees a conspiracy where there is none. NASA is part of the leftist plot to delude the world into believing in global warming, and this announcement, he goes on to suggest, may be part of it. He ridicules his producer, Sneedley, who was excited and enthusiastic about NASA’s announcement. Limbaugh then declares that he is a ‘big time science guy’ who gone past ‘science 101’. He then goes on to cast scorn and suspicion about the announcement. It’s part of some leftist plot being pursued by the agency, but he doesn’t quite know what yet. But it’s probably about global warming. Soon, he predicts, they’ll announce that they’ve found a graveyard.

Limbaugh’s a Republican broadcaster, who’s been a fixture of American right-wing radio since the 1980s, loudly applauding Ronald Reagan and ranting about how the ‘Leftists’ are trying to destroy his country. In the clip, Seder and his co-hosts and producers ridicule Limbaugh not only for his scientific ignorance – what, pray, is ‘Science 101?’, as well as the way he has openly sneered at and belittled his producer.

They then conclude the programme by further mocking him. They imitate Obama’s voice to declare that Islam is the one true religion. The Martians rejected this, which is why they were hit by a devastating drought. That’s why Obama is going to declare shariah law, and have a child from every White family in the mid-West sold into slavery in the Middle East.

This is to poke fun at Limbaugh, and the stupid, paranoid opinion amongst many American Republicans that Obama is a secret Muslim advancing the plans for an Islamic takeover of the US.

The clip shows much of what’s wrong with the American right’s attitude to science, their massive ignorance, which they think shows how perceptive they are, and their stupid paranoia about ‘leftists’. Which in this case, means anything and anyone, who isn’t as crazily right-wing as they are.

I’ve put up several pieces here about the possibility of life on Mars, and the use of certain genetically modified organisms to terraform the Red Planet. I know that several of the readers of this blog have science backgrounds and similar interests. I’ve put this up because I thought people might like to see just how stupid and ignorant Limbaugh, and by extension, his audience, is about this whole issue.

Firstly, as Seder points out, when NASA made the announcement they said it was about the state of Mars 3 billion years in the past. It’s nothing to do with global warming.

Absolutely correct. Planetary scientists now believe that there was a period during the early history of the solar system, when Mars was warm and wet. I think the National Geographical mentioned this when they did a piece on Mars in the 1980s or ’90s. It’s also discussed in Kim Stanley Robinson’s epic SF novel about the colonization of Mars, Red Mars.

What killed Mars was not global warming, but global cooling. Mars has no tectonic plates, and so it is theorized that the planet’s atmosphere was not renewed through releases of gases released from its rocks through geological forces. Over millions or billions of years, the atmosphere evaporated into space. The surface pressure is about 5 milibars – that of a laboratory vacuum. Without an atmospheric blanket to focus and increase the sun’s light, the planet cooled. Without atmospheric pressure to sustain it, water rapidly sublimates into vapour on the Martian surface. What water has survived is locked up in the ice caps, and may be as permafrost below the Martian surface.

Mars has never been cited as a warning of the dangers of global warming. That’s always been Venus. Venus lies closer to the Sun than Earth, and so has suffered runaway global warming as ever increasing amounts of carbon dioxide was released from its rocks. The result of this is that the planet is covered by a permanent cloud layer. Surface temperatures reach something like 400 degrees C, the rain is sulphuric acid, and its surface pressure is enough to squash a human flat. If you want an example of how different the histories of Mars and Venus are, go have a look, or read, the chapter ‘Blues for a Red Planet’ in Carl Sagan’s Cosmos. Sagan was a major believer in the threat of global warming, and in that episode of his epic science history blockbuster, explicitly drew a parallel between Mars’ fate and that of our own world, if we don’t cut carbon emissions.

As for finding a graveyard on Mars, some scientists have speculated on the possibility that we may find fossils of the creatures that may have lived on Mars, far back in ancient geologic time. There are also serious scientists, who have suggested that we should look for evidence of advanced extraterrestrial civilisations in the planets of our solar system. Our solar system lies in a part of the Galaxy, where the stars are an average of a single light year away from each other. That’s a short enough distance for an advanced civilization to make the difficult journey across interstellar space to another solar system. And the solar system is so old, about 4 billion years if not more, that it is statistically likely that intelligent life has arisen elsewhere in our Galaxy. And just as the Earth orbits the Sun, so the Sun orbits the centre of the Galaxy, taking 225 million years to complete one revolution. This is long enough for our Solar system to have come close to one of those other stars, harbouring alien life.

So signs of an extraterrestrial civilization may well exist on Mars. However, Mars has been dead for so long, that it’s unlikely that there exist any remains of an indigenous Martian civilization on the planet’s surface. In their entry ‘The Surface of Mars’, subtitled ‘Desert’, in their book Catalogue of the Universe, astronomers Paul Murdin and David A. Allen write

If once great cities stood here, they have crumbled to unrecognizable shapes. If trees bowed before moist zephyrs, they have returned to the dust whence they rose. If aircraft landed here, they too have vanished, or been buried beneath unknown depths of sand and rocks. (pp. 205-6).

Not all scientists are convinced that the features NASA suggested was evidence of flowing water were actually produced by it. Others believe that the marks on the surface may instead be produced by the release of other chemicals in liquid form from the underlying rock.

But if liquid water still flows on Mars, albeit it occasionally, not only does it augur well for the possible survival of some life, even if only primitive bacteria, but it also makes the planet more hospitable for possible colonization.

NASA’s claim to have found evidence of surface liquid water was therefore immensely exciting. And Limbaugh’s producer, Sneedley, was actually absolutely right to be excited about it. It’s his host, Limbaugh, who’s ignorant. And dangerously so.

No-one expects ordinary people to be experts on science. Science has advanced at such a rate that it’s too much for many ordinary people to keep update with scientific advances, some of which can be very arcane to laypeople.

But we do need people to be reasonable well-educated. And especially about threats to the planet, like global warming. It’s why there’s a need for good scientific writers and broadcasters to explain the issues clearly.

Limbaugh with his stupid denial of global warming, and his paranoid suspicion that NASA is part of some larger ‘left-wing’ plot, is actually doing the opposite. He’s disparaging real science and trying to keep people ignorant in order to promote his own, extreme right-wing views.

He’s also a danger on racial issues. A day or so ago I reported that Trump had cut funding for FBI and Department of Homeland Security initiatives against White racist terrorism. This included a charity, Life After Hate, that helps former Nazis leave these organisations without being attacked by their fellow stormtroopers. It’s a real danger. Matthew Collins, one of the founders and leaders of the anti-racist/ anti-religious extremism organization, Hope Not Hate, had to migrate to Australia in the 1990s after he appeared in a documentary exposing the violence of the NF and BNP. Obama had given $400,000 to the charity. He would have funded them sooner, but he was prevented from doing so by the ravings and possible denunciation by Limbaugh.

It’s debatable, however, how long Limbaugh will actually carry on. Far from being the influential Republican spokesman he thinks he is, his radio station in recent has been haemorrhaging sponsors and advertisers. His ratings have fallen to the point, where fewer people listen to him than to College radio stations with the range of only one or two miles. The only thing keeping him on air is money from Republican and similar extreme right-wing think tanks. If they pull out, he’s off the air.

The Fantastic Space Art of David A. Hardy

April 22, 2017

This is another couple of videos from the redoubtable Martin Kennedy showcasing the amazing work of yet another space and Science Fiction artist, David A. Hardy. Hardy is one of the longest running space and SF artist working. The entry on him in Stuart Holland’s Sci-Fi Art: A Graphic History, runs:

David Hardy’s introduction to astronomical illustration was a somewhat rushed affair. In 1954, as a mere 18-year-old, he was commissioned to produce eight black and white illustrations for a book by legendary UK astronomer Patrick Moore: Suns, Myths, and Men. He had just five days to create them before British national service-conscription-required him to join the Royal Air Force. The commission was all the more remarkable as Hardy had only painted his first piece of astronomical art four years previously, inspired by the work of Chesley Bonestell.

Since those early days, Hardy (1936-) has garnered numerous awards for artwork that spans the science fiction/hard science divide. Born in Bourneville, Birmingham, in the UK, he honed his talents painting chocolate boxes for Cadbury’s. By 1965 he had become a freelance illustrator, beginning a career that resulted in covers for dozens of books and magazines, both factual, such as New Scientist, Focus, and various astronomical publications, for which he also writes; and SF, including Analog and Fantasy & Science Fiction. 1972 saw the publication of Challenge of the Stars, which Hardy not only illustrated but co-wrote with Patrick Moore (the book was updated in 1978 as New Challenge of the Stars). A bestseller, it joined the select pantheon of book that influenced a new generation of up-and-coming astronomical artists.

By now, Hardy’s work was receiving international recognition, and in 1979 he was nominated for the Hugo Award for Best Professional Artist. Tow years later, another book followed, Galactic Tours, which as the name suggests is a “factitious” guidebook for the interstellar tourist. As a result of the book, travel company Thomas Cook approached Hardy about becoming a consultant on the future of tourism in space-long before Richard Branson had planned Virgin’s conquest of the stars.

Hardy has written an SF novel, Aurora: A Child of Two Worlds; worked on the movie The Neverending Story, and on TV (Cosmos, Horizon, The Sky at Night, Blake’s Seven), and produced record covers for – unsurprisingly – Holst’s The Planets and for bands such as Hawkwind, the Moody Blues, and Pink Floyd.

In 2004, Hardy’s long-standing partnership with Patrick Moore culminated in the award-winning Futures, in which the two explored the changing perceptions of space exploration since they first collaborated in the ’50s, the ’70s (the era of Challenge of the Stars) and into the 21st century. Artistically, Hardy has also embraced the growing digital trend that started in the approach to the new millennium. While still painting in acrylic and oil, he now uses Photoshop as a matter of course.

In March 2003, Hardy was paid perhaps the ultimate accolade an astronomical artist can receive: he had an asteroid [13329] named after him. Discovered ini September, 1998, it was christened Davidhardy=1998 SB32-high praise indeed!
(P. 130).

Several of the paintings in the video come from the Challenge of the Stars and its updated version.

The videos also include his cover illustration for Arthur C. Clarke’s The Snows of Olympus: A Garden on Mars – the History of Man’s Colonisation of Mars, which is another ‘future history’, this time of the terraforming of the Red Planet.

I have to say that I’m really impressed he also worked on Blake’s 7. This was low-budget British SF, but it had some create scripts and a really beautiful spaceship in The Liberator. And I would far rather go into space on something designed by Hardy, and operated by Thomas Cook, than by Branson.

Arthur C. Clarke Book on the Terraforming of Mars

March 18, 2017

Arthur C. Clarke – The Snows of Olympus: A Garden on Mars – The Illustrated History of Man’s Colonization of Mars (London: Victor Gollancz 1994).

A little while ago I put up a number of articles on the possible terraforming of various planets in our solar system. The prime candidate at the moment would be Mars, but people have also suggested ways to terraform Venus and the Moon. I’ve managed to dig out from my bookshelves a copy of Arthur C. Clarke’s book, The Snows of Olympus, which I bought way back in the 1990s. Clarke’s been called ‘The Space Prophet’ because of his article published in a radio hobbyists’ magazine shortly after the War predicting geostationary communications satellites. He has jokingly said in an article ‘How I Lost a Million Dollars in My Spare Time’ that he should have patented the concept, and so made himself a billionaire because of its immense value to the telecommunications industry. This book is no less prophetic in that it uses computer simulations to depict the gradual greening of the Red Planet over a thousand year period from the next few centuries to c. 3000.

The book has a prologue, in which Clarke gives the text of a speech he gave to future Martian colonists as part of the Planetary Society’s ‘Visions of Mars Project’. Launched by the late and much-missed astronomer and space visionary, Carl Sagan, this was a project to send the future colonists the gift of a collection of SF short stories about Mars aboard two probes due to land there. There’s then a short introduction in which Clarke lays out the aims of the book. The first chapter, ‘Prelude to Mars’, discusses the history of the exploration of the Red Planet by terrestrial astronomers and writers, such as Giovanni Schiaparelli, Percival Lowell, H.G. Wells and Edgar Rice Burroughs, C.S. Lewis in Out of the Silent Planet, and the controversy surrounding the supposed ‘face’ on Mars, made by Richard Hoagland and others.

Chapter 2 – ‘The Curtain Rises’ – is on the probes sent to explore Mars, such as the Mariner probes and discussion between himself, Sagan, Ray Bradbury and the JPL’s Bruce Murray at the Jet Propulsion Laboratory on the probes and their findings. He goes on to discuss Viking probes and the debate about American and Russian cooperative ventures in space research. This last ended for a time because of international tensions created by the Solidarity crisis in Poland.

Chapter 3 – ‘Going There’, describes the problems and suggested methods for reaching Mars, establishing crewed bases there, including various types of rocket from the conventional chemical to nuclear-thermal and atomic; solar sails and space elevators, George Bush seniors’ intention to launch a crewed mission to Mars by 2019, and the tasks that would immediately face the astronauts landing there.

Chapter 4- ‘Virtual Explorations’ is on the use of computers and VR to explore and map Mars, and particularly the Vistapro programme used in the generation of many of the images in the book.

Chapter 5 is on the artistic and computer depictions of Olympus Mons, the planet’s highest mountain and the gradual reclamation of its surface by vegetation, beginning with lichens, during the long centuries of terraforming. This culminates in the emergence of liquid water and creation of a sea surrounding the mountain.

Chapter 6 does the same for Eos Chasma, the ‘Chasm of the Dawn’, in the Valles Marineris.

Chapter 7 shows the same process as it would affect the Noctes Labyrinthes – the Labyrinth of Night. This forecasts the growth of forests in this part of Mars, beginning with pines but later including deciduous trees.

Chapter 8 – ‘The Longest Spring’ discusses the various methods that could be used to terraform Mars, such as coating the ice caps with carbon from Mars’ moon, Phobos, the use of orbiting mirrors to melt them, raising its temperature by turning Phobos into a miniature sun for about 40 days using ‘muon resonance’ – a form of nuclear reaction, and bombarding the planet with comets to cover it with water, and ‘Von Neumann’ machines that would gradually terraform the planet automatically.

‘Disneymars’ looks forward to a museum display and audiovisual presentation that would show the colonists what their planet would look like in the future as the terraforming progresses.

Chapter 9 – ‘Concerning Ends and Means’ discusses the moral dimension of terraforming, the immense historical importance of exploration and the need to continue this exploration to the Red Planet in order to preserve human civilisation and progress.

There are two appendices. The first is an extract from a speech, The Mars Project: Journeys beyond the Cold War, by US senator and WWII hero, Spark Matsunaga. The second, ‘So You’re Going to Mars’, is fictional advice given by the immigration authorities to people moving from Earth to Mars.

The quality of the computer graphics is mixed. Many of them, which were without doubt absolutely astonishing for the time, now look rather crude and dated as the technology has improved. Others, however, still stand up very well even today. The quality of the computer simulations of the terraforming process can be seen from this image below of what Eos Chasma might look like in 2500 AD.

There are also plenty of illustrations of Mars, rendered using more traditional artistic methods such as painting, including photos of Percival Lowell’s own drawings of what he believed was the planet’s network of canals.

Although the computer tools may have been superseded and improved in the decades since the book’s publication, I think the science, and the social issues Clarke discusses, are still solidly relevant and contemporary. Certainly there is now a popular movement to send humans to the Red Planet at some point in the coming decades, and prospective future colonists have even come forward to volunteer a few years ago. There is, however, a greater awareness of the medical dangers from radiation and microgravity that would affect – and possibly destroy – a mission to Mars. The dream, however, is still there, as shown by the success of the film The Martian a few years ago.

Florence on Terraforming Mars Using Existing Microbes

January 2, 2017

One of the pieces I put up yesterday was on a paper by two scientists in the Journal of the British Interplanetary Society, discussing the possibility of terraforming Mars using genetically engineered microbes. Florence, one of the commenters on this blog, used to be a microbiologist, and was extremely interested in the exploration of Mars and the prospect for finding life there. She commented that there are already anaerobic microbes that can exist in comparable conditions on Earth. She felt that the experiments carried designed to detect life on the Red Planet were very inadequate. She wrote

There appears little need to create GMOs for terraforming. We already have the real deal here on earth. Back 3.6 billion years ago, when first life is thought to have arrived/ developed / etc there wasn’t an oxygen based atmosphere. It was anoxic, and the first organisms (the archeao bacteria) were very sensitive to oxygen, and there are still many that find oxygen toxic. These are still found in many places including the human gut! Some microorganisms developed oxygen tolerance and that allowed them to use new food sources, and they began adding oxygen to the atmosphere. These organisms then used this evolutionary advantage to evolve and diversify. When I studied anaerobic bacteria the main problems were sensitivity to oxygen – very difficult to remove from all materials prepared in the standard lab – and the slow growth rate (making the rapid generation of results for research funding cycles pretty difficult).

Then there are the organisms that can grow in both aerobic and anaerobic environments. These are the ones that would be useful in terraforming if the aim was to develop a breathable atmosphere for humans and other animals. These live on very basic nutrients of sulphur and iron containing minerals, plus water. I think the “red” planet would be a great place to find these organisms, and vee may not even need to send ours over, but to stimulate the environmental conditions that would allow the planet to terraform itself. I recall the so-called search for life on the early Mars probes left me speechless – they were just totally inappropriate. But that’s can other story! Thank you for reminding me of the whole area of microbial life here and across the solar system! Happy New Year, too!

The paper discussing the use of GEMOs to terraform Mars did mention that some existing microorganisms had been considered, such as a variety of cyanobacteria.
Looking through the index of papers published in the Proceedings of the Founding Convention of the Mars Society: August 13-16, 1998, edited by Robert and Linda Zubrin, I did find one paper by James M. Graham and Linda E. Graham on terrestrial microbes on Mars. This was ‘Physiological Ecology of Terrestrial Microbes on a Terraformed Mars’, published in the third volume of papers. Unfortunately, I don’t have that volume, and so I really don’t know anything about the paper or its conclusions, just that it exists.

As for the inadequacy of the instruments aboard the Viking probe to detect life on the Red Planet, Dr. Heather Couper and the late Colin Pillinger also believed that they were too limited to disprove the existence of life in that part of the cosmos. Heather Couper is an astronomer, writer and broadcaster, who’s written a series of books on astronomy. A few years ago I heard her talk about life on Mars at the Cheltenham Festival of Science. Before she began speaking, she asked her audience how many of them believed there was life there. Only a few people put their hands up. She asked the same question again at the end of her talk, after she had explained the problems with Viking’s experiments, and the evidence for life. That time the majority of people put their hands up.

Dr. Colin Pillinger, who was a scientist with the Open University, also made a very strong case for life on Mars, life he hoped to find with the Beagle Probe. One of the ways life could be detected was through its waste gases, like methane. The Beagle Probe carried just such a detector, and Dr. Pillinger said, ‘So if a bacterium farts on Mars, we’ll find it.’ He was another speaker at the Cheltenham Festival of Science, and was well worth hearing. Sadly, the Beagle Probe was a disastrous failure. Rather than soft-landing, it crashed on to the Mars surface, and was destroyed.

Despite this, I still have immense respect for the man. He and his team seemed to be fighting a lone battle to send a British probe to explore the issue, and I am deeply impressed by the way he and his fellow scientists were able to mobilise public support, including celebrities like the artist, Damian Hurst. I got the impression that his team were rushed, and it may well have been this that caused the mission’s failure. But I don’t fault the man for trying, and I think he did a grand job in taking on British officialdom and winning a place for the probe aboard the Ariane craft, when the British authorities didn’t appear to be at all interested, at least, at the beginning.

It’s sad that he failed, but he was genuinely inspirational in pushing for the project. I hope that it will not be too long before someone else sends another, better probe to Mars. And I think we need more scientists, and science educators like him, who can pass on their great enthusiasm for their subject.

Two Views of a Partly Terraformed Mars

January 2, 2017

Over the past few days, I’ve been discussing on this blog the possible terraforming of Mars. Way back in the 1990s, the late Arthur C. Clarke published a book of pictures he’d generated on his computer of what Mars would look like during and after the centuries-long process. I’m afraid I cleaned that out years ago. I have, however, managed to find two pictures of a partly terraformed Mars by the artist Michael Carroll, in The Case for Mars: The Plan to Settle the Red Planet and Why We Must, by Robert Zubrin and Richard Wagner (London: Simon and Schuster 1996).

The first shows a group of explorers making their way along a defile or gully.


The second shows a view of the planet from space.


The caption for this reads

Liquid water once coursed over the face of Mars and, given the technological capability of the twenty-first century, it may once again. Several decades of terraforming could transform Mars into a relatively warm and slightly moist planet suitable some day for explorers without space-suits, although breathing gear would still be required. Returning oceans to Mars is actually a possibility for the distant future.

I think Kim Stanley Robinson explored a Mars, which after centuries of terraforming now possessed oceans, in two of his trilogy of books on the Red Planet, Blue Mars and Green Mars.

There are also a series of videos on YouTube by someone, who has used the astronomy programme Celesta, to simulate the terraformation of Venus, the Moon, Mars and Titan.

As for Titan, Stephen Baxter’s SF book of the same name concludes with two astronauts, sent on a mission to Jupiter’s moon, waking up billions of years in the future. The Sun has expanded into a Red giant, supplying this currently icy world with the heat necessary for an Earthlike environment. By this time, however, humanity is extinct and the moon’s current occupants are a race of alien explorers.

British Interplanetary Society Paper on Terraforming Mars with Microorganisms

January 1, 2017

Yesterday I put up a couple of articles on terraforming the various planets of the Solar system, including Mercury, Venus and Earth’s Moon, as well as Mars. There have been a couple of really interesting comments posted to them. Florence, one of the great people, who read this blog, stated that she was a microbiologist. She was very much looking forward to working on microorganisms for Mars, but unfortunately that, and much of the rest of the space programme, vanished.

As well as Carl Sagan’s suggestion in the 1960s that blue-green algae could be used to create a breathable atmosphere and Earthlike environment on Mars, a number of scientists have also suggested using microorganisms to terraform the Red Planet. Twenty years ago the American Astronautical Society published a series of papers, edited by Robert M. Zubrin, about the colonisation of Mars, From Imagination to Reality: Mars Exploration Studies of the Journal of the British Interplanetary Society: Part II: Base Building, Colonization and Terraformation (San Diego: Univelt 1997). This included a paper, ‘Genetic Modification and Selection of Microorganisms for Growth on Mars’ by Julian A. Hiscox and David J. Thomas.


The abstract for this paper reads

Genetic engineering has often been suggested as a mechanism for improving the survival prospects of terrestrial microorganisms when seeded on Mars. The survival characteristics that these pioneer microorganisms could be endowed with and a variety of mechanisms by which this can be achieved are discussed, together with an overview of some of the potential hurdles that must be overcome. Also, a number of biologically useful properties for these microorganisms are presented that could facilitate the initial human colonisation and ultimately the planetary engineering of Mars.

After an Introduction, in which they state that the terraformation of Mars could be a two-stage process, with the construction of an Earthlike environment by microorganisms being the first, they then proceed to the following sections:

2. Selection of Bacteria for Mars The Search for a Marsbug, which discusses the suitability of terrestrial microbes for the process, such as the cyanobacterium Chroococcidiops and the extremophiles, which occupy of extreme environments here on Earth;

3. Genetic Engineering – A simple Matter of Cut and Paste;

4. Genetic Modification and Selection;

5. Gene Expression, with subsections on

1) Survival Properties – Tolerance to Peroxides; Osmotic Adaptation; UV Resistance; Tolerance to High Intracellular Acid Concentrations; Endospore Formation;

2) General Properties, with further subsections on photosynthesis, nitrogen fixation, and denitrification;

6. Uses of GEMOS and Some Speculations,

and then finally the conclusion and acknowledgments.

The conclusion reads

The introduction of microorganisms on Mars will greatly facilitate colonisation, both during initial attempts and in establishment of a stable ecosystem, either in enclosed habitats or at the end of ecopoiesis or terraformation. During the initial stages of ecopoiesis climatic conditions on Mars will be limiting for most terrestrial microorganism. By using genetic modification and directed selection under simulated Martian conditions, it may be possible to greatly enhance the survival capability of microorganisms during the alteration of the Martian climate to more clement conditions. Such microorganisms could be used to facilitate any planetary engineering effort. For example, they could be used to release Co2 and N2 from putative carbonate and nitrate deposits.

The genetic alteration of microorganisms will not be so much of a problem of introducing foreign genes into the organism but more a matter of understanding and controlling the regulatory pathways for the expression of such genes. However, such understandings will provide valuable insights into genetics, not only for increasing the productivity of microorganisms on Mars but possibly for Earth.

I’ve got very strong reservations about genetic engineering and modification, but here there is a strong case if it can be used to bring life to a sterile world. Assuming, that is, that Mars does not already possess life. In a way, the article’s ironic. Over a century ago, H.G. Wells had a germ, the common cold, destroy the invading Martians in his book, The War of the Worlds. Now terrestrial scientists are discussing using such organisms as ways to creating a living environment on the Red Planet.

Terraforming the Moon by Comet

December 31, 2016

In my last blog post, I discussed the passed in David A. Hardy’s book, Atlas of the Solar System, in which he described the possible methods which might be used in the future to transform Mercury, Venus, the Moon and Mars into worlds, where humans and other creatures could live in the open, instead of the enclosed environments they need now to protect them from the harsh conditions of space. In the case of Venus, comets would be used to increase the planet’s rotation from its current 224 Earth days to a terrestrial day, and give the planet water. Looking through YouTube, I found this video by Fraser Cain, in which he talks about using the same method to terraform the Moon, as suggested by the space scientist and SF writer, Gregory Benford. This is part of a series of videos on space and space colonisation. At the beginning of the video, he mentions a previous one about the terraforming of Venus.

The explanatory section on the YouTube page provides this transcript of his talk.

In our episode about terraforming Venus, we talked about cooling the planet with a giant sunshade, and then hand-wavingly bind up all that carbon dioxide.

We did the same with Mars, filling the atmosphere with greenhouse gasses to warm it up, and releasing the planet’s vast stores of C02 to thicken the atmosphere. Then just crash in a few comets worth of water and upgrade them to to a 3 star resort.

We’re pitching this as a new series on the Discovery Network, called “Flip My Planet – Canada”.

Now let’s turn our imagination towards another rockball that is really more of a fixer-upper: The Moon. I know, you never even thought of the Moon as a place that we could possibly terra-renovate. Go ahead and imagine with me all the possibilities of a verdant green and blue little world hanging in the night sky. Doesn’t that sound great?

So, what does it take? Do we tear it down and just use the orbital lot space? Should we raise it up and lay a new foundation? Or could we get away with a few coats of paint and adding an atrium on the backside?

Fortunately for me, scientist and sci-fi author Gregory “Planetary Makeover” Benford has already done the math.

Let’s take a look at what we’d need to get the Moon habitable. For starters, the fact that the Moon is so close to Earth is a huge advantage. This is like living on the same block as a Home Depot, and we won’t have to travel far to get supplies and equipment to and from our project.

We’re going to need an atmosphere thick enough to breathe and trap in the Sun’s heat. This takes wild comet capture and harvest, tear them apart and smash them into the Moon.

Benford notes that you probably want be careful not to let an entire comet collide with the Moon because it might spray your primary investment home with debris and do a little damage to the resale value, or potentially annoy your tenants.

This could get bad enough that we’d have to terraform Earth to get it livable again, and you’d need to bring in Mike Holmes to publicly shame us and put our primary residence back in order.

After you’d splattered a few comets on the Moon, it would have an atmosphere almost immediately. The transfer of momentum from the comet chunks would get the Moon rotating more rapidly.

If you invest a little more in your planning stage, you could get the Moon spinning once every 24 hours, and even tilt its axis to get seasons. Benford estimates that we’d need 100 Halley’s mass comets to get the job done. This might sound like a pretty tall order, but it’s tiny compared to number of comets we’d need for your Mars or Venus real estate scheme.

The maintenance and upkeep isn’t going to be without its challenges. Low gravity on the Moon means that it can’t hold onto its atmosphere for longer than a few thousand years.

Once you got the process going, you’d need to be constantly replenishing our your orbital cottage with fresh atmosphere. Fortunately, we’ve got a whole Solar System’s worth of ice to exploit.

The benefits of a terraformed summer home on the Moon are numerous. For example, if the Moon had an atmosphere as thick as the Earth’s, you could strap on a pair of wings and fly around in the 1/6th gravity.

The enormous gravity of the Earth would pull the Moon’s oceans around the planet with 20 meter tides. You could surf the tide for kilometers as it washes across the surface in a miniature version of the shallow water scene in Interstellar.

This might be the greatest sponsorship opportunity for GoPro of all time. Look out Kiteboarding, you’re about to get more extreme.

Everyone always wants to talk about terraforming Venus or Mars. Let them be, that’s too much work. The next time someone brings it up at D&D night, you can blow their minds with your well crafted argument on why we want to start with the Moon.

I can remember David A. Hardy illustrating a few articles on future human habitats on the Moon, showing people enjoying themselves flying around and swimming at just such a lunar resort. One of these was for an article in the sadly short-lived space and astronomy magazine, New Voyager. The resort was in an enclosed dome, rather than on the terraformed surface. The Scots space scientist, Duncan Lunan, in his book, Man and the Planets, also suggested that to prevent the Moon’s atmosphere from being lost to space, the whole planet should be contained with a kind of giant inflatable bubble. This is waaaay beyond modern technological capability, but not, perhaps, that of the future. So perhaps at some point in the far future, the Moon may also join Earth as a living, habitable world.
