Future Possibilities 2

The second part of this quick review of the Future Decoded conference looks at things a little further ahead. This was also going to be the final part, but as there’s a lot of cool stuff to chat about, I’ve decided to add part 3…

Prediction of data demand vs supply (IDC.org)
Prediction of data demand vs supply (IDC.org)

So here’s a problem that is a minor one at the moment, but with the potential to grow into a major one. In short, the world has a memory shortage! Already we are generating more bits and bytes that we would like to store, than we have capacity for. Right now it’s an inconvenience rather than a crisis, but year by year the gap between wish and actuality is growing. If growth in both these areas continues as at present, within a decade we will only be able to store about a third of what we want. A decade or so later that will drop to under one percent.

Think about it on the individual level. You take a short video clip while on holiday. It goes onto your phone. At some stage you back it up in Dropbox, or iCloud, or whatever your favourite provider is. Maybe you keep another copy on your local hard drive. Then you post it to Facebook and Google+. You send it to two different WhatsApp groups and email it to a friend. Maybe you’re really pleased with it and make a YouTube version. You now have ten copies of your 50Mb video… not to mention all the thumbnail images, cached and backup copies saved along the way by these various providers, which you’re almost certainly not aware of and have little control over. Your ten seconds of holiday fun has easily used 1Gb of the world’s supply of memory! For comparison, the entire Bible would fit in about 3 Mb in plain uncompressed text, and taking a wild guess, you would use well under that 1 Gb value to store every last word of the world’s sacred literature. And a lot of us are generating holiday videos these days! Then lots of cyclists wear helmet cameras these days, cars have dash cams… and so on. We are generating prodigious amounts of imagery.

So one solution is that collectively we get more fussy about cleaning things up. You find yourself deleting the phone version when you’ve transferred it to Dropbox. You decide that a lower resolution copy will do for WhatsApp. Your email provider tells you that attachments will be archived or disposed of according to some schedule. Your blog allows you to reference a YouTube video in a link, rather than uploading yet another copy. Some clever people somewhere work out a better compression algorithm. But… even all these workarounds together will still not be enough to make up for the shortfall, if the projections are right.

Holiday snaps aside, a great deal of this vast growth in memory usage is because of emerging trends in computing. Face and voice recognition, image analysis, and other AI techniques which are now becoming mainstream use a great deal of stored information to train the models ready for use. Regular blog readers will know that I am particularly keen on voice assistants like Alexa. My own Alexa programming doesn’t use much memory, as the skills are quite modest and tolerably well written. But each and every time I make an Alexa request, that call goes off somewhere into the cloud, to convert what I said (the “utterance”) into what I meant (the “intent”). Alexa is pretty good at getting it right, which means that there is a huge amount of voice training data sitting out there being used to build the interpretive models. Exactly the same is true for Siri, Cortana, Google Home, and anyone else’s equivalent. Microsoft call this training area a “data lake”. What’s more, there’s not just one of them, but several, at different global locations to reduce signal lag.

Hopefully that’s given some idea of the problem. Before looking at the idea for a solution that was presented the other day, let’s think what that means for fiction writing.  My AI persona Slate happily flits off to the asteroid belt with her human investigative partner Mitnash in Far from the Spaceports. In Timing, they drop back to Mars, and in the forthcoming Authentication Key they will get out to Saturn, but for now let’s stick to the asteroids. That means they’re anywhere from 15 to 30 minutes away from Earth by signal. Now, Slate does from time to time request specific information from the main hub Khufu in Earth, but necessarily this can only be for some detail not locally available. Slate can’t send a request down to London every time Mit says something, just so she can understand it. Trying to chat with up to an hour lag between statements would be seriously frustrating. So she has to carry with her all of the necessary data and software models that she needs for voice comprehension, speech, and defence against hacking, not to mention analysis, reasoning, and the capacity to feel emotion. Presupposing she has the equivalent of a data lake, she has to carry it with her. And that is simply not feasible with today’s technology.

So the research described the other day is exploring the idea of using DNA as the storage medium, rather than a piece of specially constructed silicon. DNA is very efficient at encoding data – after all, a sperm and egg together have all the necessary information to build a person. The problems are how to translate your original data source into the various chemical building blocks along a DNA helix, and conversely how to read it out again at some future time. There’s a publicly available technical paper describing all this. We were shown a short video which had been encoded, stored, and decoded using just this method. But it is fearfully expensive right now, so don’t expect to see a DNA external drive on your computer anytime soon!

Microsoft data centre (ZDNet/Microsoft)
Microsoft data centre (ZDNet/Microsoft)

The benefits purely in terms of physical space are colossal. The largest British data centre covers the equivalent of about eight soccer grounds (or four cricket pitches), using today’s technology. The largest global one is getting on for ten times that size. With DNA encoding, that all shrinks down to about a matchbox. For storytelling purposes that’s fantastic – Slate really is off to the asteroids and beyond, along with her data lake in plenty of local storage, which now takes up less room and weight than a spare set of underwear for Mit. Current data centres also use about the same amount of power as a small town, (though because of judicious choice of technology they are much more ecologically efficient) but we’ll cross the power bridge another time.

However, I suspect that many of us might see ethical issues here. The presenter took great care to tell us that the DNA used was not from anything living, but had been manufactured from scratch for the purpose. No creatures had been harmed in the making of this video. But inevitably you wonder if all researchers would take this stance. Might a future scenario play out that some people are forced to sell – or perhaps donate – their bodies for storage? Putting what might seem a more positive spin on things, wouldn’t it seem convenient to have all your personal data stored, quite literally, on your person, and never entrusted to an external device at all? Right now we are a very long way from either of these possibilities, but it might be good to think about the moral dimensions ahead of time.

Either way, the starting problem – shortage of memory – is a real one, and collectively we need to find some kind of solution…

And for the curious, this is the video which was stored on and retrieved from DNA – regardless of storage method, it’s a fun and clever piece of filming (https://youtu.be/qybUFnY7Y8w)…

 

Future possibilities 1

This is the first of two posts in which I talk about some of the major things I took away from the recent Future Decoded conference here in London. Each year they try to pick out some tech trends which they reckon will be important in the next few years.

Disability statistics by age and gender (Eurostat)
Disability statistics by age and gender (Eurostat)

This week’s theme is to do with stuff which is available now, or in the immediate future. And the first topic is assisting users. Approximately one person in six in the world is considered disabled in some way, whether from birth or through accident or illness (according to a recent WHO report). That’s about about a billion people in total. Technology ought to be able to assist, but often has failed to do so. Now a variety of assistance technologies have been around for a while – the years-old alt text in images was a step in that direction – but Windows 10 has a whole raft of such support.

Now, I am well aware that lots of people don’t like Win 10 as an operating system, but this showed it at its best. When you get to see a person blind from birth able to use social media, and a lad with cerebral palsy pursuing a career as an author, it doesn’t need a lot of sales hype. Or a programmer who lost use of all four limbs in an accident, writing lines of code live in the presentation using a mixture of Cortana’s voice control plus an on-screen keyboard triggered by eye movement. Not to mention that the face recognition login feature provided his first opportunity for privacy since the accident, as noone else had to know his password.

But the trend goes beyond disabilities of a permanent kind – most of us have what you might call situational limitations at various times. Maybe we’re temporarily bed-ridden through illness. Maybe we’re simply one-handed through carrying an infant around. Whatever the specific reason, all the big tech companies are looking for ways to make such situations more easily managed.

Another big trend was augmented reality using 3d headsets. I suppose most of us think of these as gaming gimmicks, providing another way to escape the demands of life. But going round the exhibition pitches – most by third-party developers rather than Microsoft themselves – stall after stall was showing off the use of headsets in a working context.

Medical training (Microsoft.com and Case Western Reserve University)

Training was one of the big areas, with trainers and students blending reality and virtual image in order to learn skills or be immersed in key situations. We’ve been familiar with the idea of pilots training on flight simulators for years – now that same principle is being applied to medical students and emergency response teams, all the way through to mechanical engineers and carpet-layers. Nobody doubts that a real experience has a visceral quality lacking from what you get from a headset, but it has to be an advantage that trainees have had some exposure to rare but important cases.

This also applies to on-the-job work. A more experienced worker can “drop in” to supervise or enhance the work of a junior one without both of them being physically present. Or a human worker can direct a mechanical tool in hostile environments or disaster zones. Or possible solutions can be tried out without having to make up physical prototypes. You can imagine a kind of super-Skype meeting, with mixed real and virtual attendance. Or a better way to understand a set of data than just dumping it into a spreadsheet – why not treat it as a plot of land you can wander round and explore?

Now most of these have been explored in fiction several times, with both their positive and negative connotations. And I’m sure that a few of these will turn out to be things of the moment which don’t make it into everyday use. And right now the dinky headsets which make it all happen are too expensive to find in every house, or on everyone’s desk at work – unless you have a little over £2500 lying around doing nothing. But a lot of organisations are betting that there’ll be good use for the technology, and I guess the next five years will show us whether they’re right or wrong. Will these things stay as science fiction, or become part of the science of life?

So that’s this week – developments that are near-term and don’t represent a huge change in what we have right now. Next time I’ll be looking at things further ahead, and more speculative…

 

 

Left behind by events, part 2

So, picking up the story where l left off two weeks ago, it’s time today to look at science fiction set in the near future from its author. Last time the focus was mainly on stories set hundreds of years in the future, where the problem is often that the technology seems pitched at too low a level. But there are different pitfalls with telling a tale in the next couple of generations. Here, an author may well assume that all kinds of things will happen quickly, when in fact they take much longer.

Flying car from Bladerunner (PInterest)
Flying car from Bladerunner (PInterest)

Flying cars are a stock image for a lot of stories, including Back to the Future and Bladerunner. Now, cars have changed in lots of ways over the span of my lifetime, but they don’t fly (and we still don’t have hoverboards). Yes, periodically there are optimistic announcements that they’re in development, but they certainly aren’t normal consumer items. The future bits of Back to the Future are set in 2015, and the original Bladerunner in 2019, so both are very contemporary.

Interceptors from moonbase in TV series UFO (PInterest)
Interceptors from moonbase in TV series UFO (PInterest)

Likewise, lots of science fiction authors assumed that we would have a moon base well before now, and that manned space missions would have visited other places in the solar system. One of my favourite books, Encounter with Tiber, written in 1996, thought it credible we would have a lunar base by around 2020.  Space 1999 and the TV series UFO were even more optimistic. The prominence of the ISS, orbiting a mere two or three hundred miles from the Earth, was not often imagined, nor the enormous success of unmanned exploratory probes. Missions like Dawn, to the asteroid belt, or New Horizons, to Pluto and beyond, don’t feature. Still less the Hubble space telescope, or the LIDO gravity wave detector, which spectacularly hit the news this week.

Social change seems profoundly hard to predict. Orwell’s 1984 still has the capacity to grip us with its stark picture of state control, but actually its vision of the future is wrong in all kinds of ways. A great many authors assumed – with good reason – that a third world war would take place in the 20th century. EE (Doc) Smith’s Triplanetary simply had “19–?” as the setting for an atomic missile war, following after “1918” and “1941”. Do Androids Dream of Electric Sheep (the short story behind Bladerunner) presupposes a war and heavy resulting pollution behind the drive to spread to other planets, and the construction of android replicants as labourers.

But all of these stories remain worth reading. We often judge the value of a story more for its human drama, and its ability to convincingly present a human response to crisis, than for the accuracy of its timeline. That is as it should be, I think.

Film Swordfish (IMDB)
Film Swordfish (IMDB)

I sometimes read criticisms of fiction which focus on the correctness or otherwise of minute details in the text, and sometimes they miss the point. Most of us don’t know the exact terminology of the parts of modern American handguns, and most of us wouldn’t know if the wrong word was used – yes, I read a scathing comment from one reviewer on just this subject a while back. But if the story holds up, most of us don’t mind. Then there’s my own area of expertise – programming. I find it hilarious when expert coders are depicted in films as hammering out on a keyboard at lightning rate without looking at either their hands or the screen. We just don’t work like that. A great deal of time is actually spent in copy-and-paste from geeky sites like StackOverflow (followed by a fair amount of careful reconfiguration). But if the story’s good, I’ll happily overlook that.

There’s certainly a place for research, and good research, in any area of fiction, but not pursued, surely, at the cost of the story and all of its other dimensions alongside the factual ones. So yes – science fiction stories set in the near future often do get things wrong, but often that doesn’t really matter.

Left behind by events, part 1

This is the first part of two, in which I look at the ways in which books show their age.

I read a lot of science fiction, and I watch a fair number of science fiction films and TV series. The latest addition is Star Trek Discovery, the latest offering in that very-long-running universe. For those who don’t know, it’s set in a time frame a few years before the original series (the one with Captain Kirk), and well after the series just called Enterprise.

Discovery bridge (TrekNews)
Discovery bridge (TrekNews)

Inevitably the new series has had a mixed reception, but I have enjoyed the first couple of episodes. But the thing I wanted to write about today was not the storyline, or the characters, but the presentation of technology. The bridge of the starship Shenzhou looked just like you’d imagine – lots of touch screen consoles, big displays showing not just some sensor data but also some interpretive stuff so you could make sense of it. And so on. It looked great – recognisable to us 21st century folk used to our own touch screen phones and the like, but futuristic enough that you knew you couldn’t just buy it all from Maplin.

Original series Enterprise bridge (PInterest)

But herein lies the problem. Look back at an old episode of the original series, and the Enterprise bridge looks really naff! I dare say that back in the 1960s it also gave the impression of “this is cool future stuff”, but it certainly doesn’t look as though it’s another decade or so on from the technological world of Discovery.

Basically, our ability to build cool gadgets has vastly outstripped the imagination of authors and film makers. Just about any old science fiction book suffers from this. You find computers on board spaceships which can think, carry out prodigiously complex calculations, and so on, but output their results on reams of printed paper. Once you start looking, you can find all manner of things like this.

Forbidden Planet - The Tempest in space (DenOfGeek)
Forbidden Planet – The Tempest in space (DenOfGeek)

Now, on one level this doesn’t matter at all. The story is the main thing, and most of us can put up with little failures of imagination about just how quickly actual invention and design would displace what seemed to be far-fetched ideas. On the whole we can forgive individual stories for their foibles. If it’s a good story, we don’t mind the punched-card inputs, paper-tape outputs, and so on. We accept that in the spirit that the author intended. Also, many authors are not so very interested in the mechanics of the story, or how feasible the science is, but in different dimensions. How might people react in particular circumstances? What are the moral dimensions involved? What aspects of the story resonate most strongly with present-day issues?

The particular problem that Discovery has is simply that it is part of a wider set of series, and we already thought we knew what the future looked like! A particular peril for any of us writing a series of books.

Now it’s not just science fiction that can be left behind by the march of events. Our view of history can, and has, changed as new evidence comes to light. Casual assumptions that one generation makes about past societies, interactions, and chronology may be turned over a few years down the line. Sometimes we look at the ways in which older authors presented things and cringe. Historical fiction books might easily be overtaken by research and deeper understanding, just as much as science fiction. It’s a risk we all face.

Next time – some thoughts about my own science fiction series, Far from the Spaceports, and the particular things in that story that might get left behind. And also, the particular problems of writing about the near-future.

A research snippet

I thought today I’d share some research I have been doing for my WIP science fiction book, The Liminal Zone.

Full moon (NASA/JPL)
Full moon (NASA/JPL)

For various plot reasons I needed to know the answer to the following problem. Suppose you were standing on the surface of Pluto’s moon Charon, looking up at Pluto, fully lit by the sun… how bright would that be compared to looking up at the full moon from Earth?

This depends on a few factors:

  1. How bright is Pluto compared to our Moon?
  2. How big are Pluto and Charon compared to Earth and the Moon?
  3. What is the separation between Pluto and Charon compared to that between Earth and Moon?
  4. How much light from the sun falls on Pluto or Charon compared to Earth and Moon?

The relationship between these various factors boil down to a fairly simple equation – comparing everything to the full moon brightness, which is fairly familiar to us, you have to:

  1. Scale up by the ratio of intrinsic reflectivity of the two bodies (called the albedo)
  2. Scale up by the ratio of the apparent area of sky covered by the two bodies
  3. Scale down by the square of the relative distance from the sun.

The apparent area can be calculated relatively easily knowing the radius of the body in question and the distance apart.

At this point you start looking up the raw figures from any of several science sites (a handy list follows below).

Earthrise from lunar orbit (NASA/JPL)
Earthrise from lunar orbit (NASA/JPL)

Let’s first think about the simpler problem of how bright a “Full Earth” is as seen from the Moon. The Earth is, on average, 2.5 times as reflective as the Moon (that’s averaging over cloudy and clear skies, land and water, etc), and the area of sky it covers is about 14 times that of the Moon. So a Full Earth as seen from the Moon is about 35 times as bright as the Full Moon as seen from Earth. Quite a sight.

Charon from New Horizons spacecraft (NASA/JPL)
Charon from New Horizons spacecraft (NASA/JPL)

Let’s move out to Pluto, and imagine we are standing looking up at a “Full Charon”. Charon is brighter than the Earth, is much smaller, much closer to Pluto than our Moon is to us, and much much further away from the sun (forty times further on average).

When you put all those figures together you find that the apparent diameter of Charon in Pluto’s sky is nearly eight times that of our Moon, so nearly sixty times the apparent area. Scale up for the extra brightness and down for the distance from the sun, and you find that Charon has about 1/6 of the brightness of our full moon. Probably still just enough to cast shadows.

Pluto from New Horizons spacecraft (NASA/JPL)
Pluto from New Horizons spacecraft (NASA/JPL)

And finally, looking up at a “Full Pluto” from Charon. Pluto is about twice the size of Charon so about four times the area. By way of comparison, that means Pluto would nicely fit inside either the top or bottom half of the constellation Orion – between belt and shoulders, or belt and feet. Pluto is also brighter than Charon. Put that all together and you find that Pluto’s full light is about two thirds that of a full moon here.

I found this quite a remarkable fact when I crunched the numbers. Go all the way out from our Earth to the furthest of the standard nine planets, and the experience of standing on Charon looking up at Pluto is almost the same – in terms of brightness – as standing here looking up at the Moon. A useful comparison for my character, who is doing just that.

Facts and figures for the curious…
Albedo values (average)
  • Moon 0.12
  • Earth 0.3
  • Charon 0.45
  • Pluto 0.6
Radius values
  • Moon 1737 km
  • Earth 6371 km
  • Charon 606 km
  • Pluto 1187 km
Distances from planet to moon
  • Earth-Moon distance 384,400 km
  • Pluto-Charon distance 18,384 km
Apparent angular size
  • Moon from Earth 0.5 degrees
  • Earth from Moon 1.9 deg
  • Charon from Pluto 3.8 deg
  • Pluto from Charon 7.4 deg

 

 

 

Mostly about YouTube

Just a short post today to highlight a YouTube video based around one of the Polly conversations from Timing that I have been talking about recently. This one is of Mitnash, Slate, Parvati and Chandrika talking on board Parvati’s spaceship, The Parakeet, en route to Phobos. The subject of conversation is the recent wreck of Selif’s ship on Tean, one of the smaller asteroids in the Scilly isles group…

The link is: https://youtu.be/Uv5L0yMKaT0

While we’re in YouTube, here is the link to the conversation with Alexa about Timing… https://youtu.be/zLHZSOF_9xo

It’s slow work, but gradually all these various conversations and readings will get added to YouTube and other video sharing sites.

More about Polly… and Pluto besides

Today’s blog is mainly about the mp3 conversation extracts from Timing, which I talked about last week. And right up front here are links to my favourite two…

  • On board Rydal’s ship, the Heron… http://datascenesdev.com/Alexa/voicefiles/All_Extract_A.mp3
  • On board Parvati’s ship, the Parakeet… http://datascenesdev.com/Alexa/voicefiles/All_Extract_C.mp3

 

While talking about Timing, it seems a good idea to remind everyone about a recent review which captured neatly a great deal of what  was trying to convey in the story: “a story that provides questions as well as answers, thrill and satisfaction, and an adventure that can’t be beat“.

Sometime in the next couple of weeks they’ll be uploaded to YouTube, but for now they are just audio links included below and on the appropriate blog page. You’ll find more about this below. In passing, there’s a small prize available for the first person who correctly spots what’s wrong with the voice selection for Chandrika! Also, and unrelated to that, you’ll hear that not all of the voices are equally successful. I shall continue to tweak them, so hopefully the quality will steadily improve.

But before that, NASA just released two YouTube videos to celebrate the two year anniversary of when the New Horizons probe was at nearest approach to Pluto and Charon. They have turned the collection of images and other telemetry into flyby simulations of the dwarf planet and its moon, as though you were manoeuvring over them. Both the colours and the vertical heights of surface features have been exaggerated so you can get a better sense of what you are seeing, but that aside, it’s as close as most of us will get to personally experiencing these places.

  • Charon: https://youtu.be/f0Q7O7TZ7Ks

OK, back to Polly. As well as specifying which of several different voices you want, you can give Polly some metadata about the sentence to help generate correct pronunciation. Last week I talked about getting proper nouns correct, like Mitnash. But in English you also get lots of words which are spelled the same but pronounced differently – homonyms. The one which I ran into was “minute”, which can either be a unit of time (min-nit) or something very small (my-newt). Another problem case I found was “produce” – was I expecting the noun form (prod-yuce) or the verb (pro-deuce)?

In all such cases, Polly tries to guess from context which you mean, but sometimes guesses wrong. Happily you can simply add some metadata to say which you want. Sometimes this is simply a matter of adding in a tag saying “I want the noun”. Other times you can say which of several alternate senses of the word you want, and simply check the underlying list until you find the right one. And if all else fails, there’s always the option of spelling it out phonetically…

 

 

More about AI and voice technology

A couple of weeks ago I went to a day event put on by Amazon showcasing their web technologies. My own main interests were – naturally – in the areas of AI and voice, but there was plenty there if instead you were into security, or databases, or the so-called “internet of things”.

Amazon Dot - Active
Amazon Dot – Active

Readers of this blog will know of my enthusiasm for Alexa, and perhaps will also know about the range of Alexa skills I have been developing (if you’re interested, go to the UK or the US sites). So I thought I’d go a little bit more into both Alexa and the two building blocks which support Alexa – Lex for language comprehension, and Polly for text-to-speech generation.

Alexa does not in any substantial sense live inside your Amazon Echo or Dot – that simply provides the equivalent of your ears and mouth. Insofar as the phrase is appropriate, Alexa lives in the cloud, interacting with you by means of specific convenient devices. Indeed, Amazon are already moving the focus away from particular pieces of hardware, towards being able to access the technology from a very wide range of devices including web pages, phones, cars, your Kindle, and so on. When you interact with Alexa, the flow of information looks a bit like this (ignoring extra bits and pieces to do with security and such like).

Alexa information flows (simplified)
Alexa information flows (simplified)

And if you tease that apart a little bit then this is roughly how Lex and Polly fit in.

Lex and Polly information flows (simplified)

So for today I want to look a bit more at the two “gateway” parts of the jigsaw – Lex and Polly. Lex is there to sort out what it is you want to happen – your intent – given what it is you said. Of course, given the newness of the system, every so often Lex gets it wrong. What entertains me is not so much those occasions when you get misunderstood, but the extremity of some people’s reaction to this. Human listeners make mistakes just like software ones do, but in some circles each and every failure case of Lex is paraded as showing that the technology is inherently flawed. In reality, it is simply under development. It will improve, but I don’t expect that it will ever get to 100% perfection, any more than people will.

Anyway, let’s suppose that Lex has correctly interpreted your intent. Then all kinds of things may happen behind the scenes, from simple list lookups through to complex analysis and decision-making. The details of that are up to the particular skill, and I’m not going to talk about that.

Instead, let’s see what happens on the way back to the user. The skill as a whole has decided on some spoken response. At the current state of the art, that response is almost certainly defined by the coder as a block of text, though one can imagine that in the future, a more intelligent and autonomous Alexa might decide for herself how to frame a reply. But however generated, that body of text has to be transformed into a stream of spoken words – and that is Polly’s job.

A standard Echo or Dot is set up to produce just one voice. There is a certain amount of configurability – pitch can be raised or lowered, the speed of speech altered, or the pronunciation of unusual words defined. But basically Alexa has a single voice when you use one of the dedicated gadgets to access her. But Polly has a lot more – currently 48 voices (18 male and 30 female), in 23 languages. Moreover, you can require that the speaker language and the written language differ, and so mimic a French person speaking English. Which is great if what you want to do is read out a section of a book, using different voices for the dialogue.

That’s just what I have been doing over the last couple of days, using Timing (Far from the Spaceports Book 2) as a test-bed. The results aren’t quite ready for this week, but hopefully by next week you can enjoy some snippets. Of course, I rapidly found that even 48 voices are not enough to do what you want. There is a shortage of some languages – in particular Middle Eastern and Asian voices are largely absent – but more will be added in time. One of the great things about Polly (speaking as a coder) is that switching between different voices is very easy, and adding in customised pronunciation is a breeze using a phonetic alphabet. Which is just as well. Polly does pretty well on “normal” words, but celestial bodies such as Phobos and Ceres are not, it seems, considered part of a normal vocabulary! Even the name Mitnash needed some coaxing to get it sounding how I wanted.

The world of Far from the Spaceports and Timing (and the in preparation Authentication Key) is one where the production of high quality and emotionally sensitive speech by artificial intelligences (personas in the books) taken for granted. At present we are a very long way from that – Alexa is a very remote ancestor of Slate, if you like – but it’s nice to see the start of something emerging around us.

Friday June 30th was International Asteroid Day!

And no, I hadn’t realised this myself until a couple of days before… but NASA and others around the world had a day’s focus on asteroids. Now, to be sure most of that focus was looking at the thorny question of Near Earth Objects, both asteroids and comets, and what we might be able to do if one was on a collision course.

But it seemed to me that this was as good a time as any to celebrate my fictional Scilly Isle asteroids, as described in Far from the Spaceports and Timing (and the work in progress provisionally called The Authentication Key). In those stories, human colonies have been established on some of the asteroids, and indeed on sundry planets and moons. These settlements have gone a little beyond mining stations and are now places that people call home. A scenario well worth remembering on International Asteroid Day!

“The inner turmoil of The Lady, as she struggles with the Mirror to gain access to the people she comes in contact with, drives the tale as the Mirror cautions her time and again about the dangers involved.  The conclusion of the tale, though a heart rending scene, is also one of hope as The Lady finally finds out who she is.”

The Review said:
“Half Sick of Shadows is in a genre all its own, a historical fantasy with some science fiction elements and healthy dose of mystery, it is absolutely unique and a literary sensation. Beautifully written, with an interesting storyline and wonderful imagery, it is in a realm of its own – just like the Lady of Shalott… It truly is mesmerising.”

Colonising Mars?

Elon Musk, founder and CEO of SpaceX, has made no secret of his plans for facilitating a colony on Mars for a long time now. But last September, in a public presentation, he explained it all in considerably more detail. The reasoning, and the raw logistical figures behind it, are still available. His credibility is built around the SpaceX programme. This in turn is based on a concept of reusing equipment rather than throwing it away each launch, and it has had a string of successes lately. The initial booster stage now returns to a landing platform, there to go through a process which recommissions it for another launch.

Quite apart from any recycling benefits, this then allows SpaceX to seriously undercut other firms’ prices of putting satellites into orbit. It still couldn’t be called cheap – one set of figures quotes $65 million – but that’s only about one sixth of the regular cost. If you’re happy to know that your equipment is going into orbit on a rocket that is not brand new, it’s a huge saving. Every successful launch, return to base, and relaunch, adds to buyers’ confidence that the procedure can be trusted.

But the big picture goes well beyond Earth orbit. Musk believes that the best way to mitigate the risks of life on Earth – global warming, conflict, extremist views of all kinds, and so on – is to spread out more widely. In a recent lecture, Stephen Hawking has said essentially the same thing. And in Musk’s  vision, Mars is a better bet than the moon for this, for a whole cluster of reasons including the presence of an atmosphere (albeit a thin one compared to here) and a greater likeness to Earth in terms of gravity and size.

So reusable rockets into Earth orbit are simply a starting point. Once you have a reasonably-sized fleet of such things, you can build larger objects already in space, and fly them over to Mars when the orbital positions are ideal. The logic of gravitational pull around a planet means that the hardest, and most energy-intensive part is needed to get you from the surface up to a stable orbit. Once there, much gentler and longer-lasting means of propulsion will get you onward bound.

To take a contemporary situation, NASA’s Dawn probe is currently orbiting the asteroid Ceres. Its hydrazine fuel, which powers the little manoeuvring and attitude thrusters, is nearly exhausted. The mission control team are trying to decide on the best course of action. In its current high orbit only a few months of fuel remain. A closer orbit, which would give better quality pictures, would use it up in a matter of weeks. But using the main ion drive, a different power source altogether, to go somewhere else would probably give a few years of science. Fairly soon we should hear which option they have chosen, and where they consider the best balance is between risk and reward. The message for here is that staying close to a planet, or taking off from one, is costly in terms of fuel.

So Musk reckons that over the course of a century or so, he can arrange transportation for a million Martian colonists. In terms of grand sweep, it is so far ahead of anyone else’s plans as to seem impossible at first sight. But if all goes according to his admittedly ambitious plan, the first of many journeys could take place ten years from now. He – and I for that matter – might not live to see the Martian population reach a million, but he certainly expects to see it firmly established.

With Far from the Spaceports, its sequel Timing, and the work-in-progress provisionally called The Authentication Key, I deliberately did not fix a future date. It’s far enough ahead of now that artificial intelligence is genuinely personal and relational – sufficiently far ahead that it is entirely normal for a human investigator to be partnered long-term on an equal basis with an AI persona. None of the present clutch of virtual assistants have any chance at all of this, and my guess is that we are talking many generations of software development before this could happen. It’s also far enough ahead that there are colonies in many locations – certainly out as far as the moons of Saturn, and I am thinking about a few “listening post” settlements further out (watch this space – the stories aren’t written yet!). However, I hadn’t really thought in terms of a million colonists on Mars, and it may well be that, as happens so often in science fiction, real events might overtake my scenario a lot quicker than I thought likely.

Back with Musk’s proposal, one obvious consequence of the whole reuse idea is that the cost per person of getting there drops hugely. This buy-in figure is typically quoted as something like $10 billion. But the SpaceX plan drops this down to around $20,000 – cheaper than the average house price in the UK. I wonder how many people, given the chance, would sell up their belongings here in exchange for a fresh start on another planet?

I was wondering what image to finish with, and then came across this NASA/JPL picture of the Mars Curiosity Rover as seen from the Mars Orbiter (the little blue dot roughly in the middle)… a fitting display of the largeness of the planet compared to what we have sent there so far.
