Ultima Thule

Today’s blog is focused on the next target of the New Horizons probe, which back in July 2015 sent back such remarkable pictures of Pluto and Charon. But before that, here’s a quick reminder of this week’s Kindle Countdown deals for Far from the Spaceports and Timing – £0.99 / $0.99 for the next couple of days. Follow these links…

Right. New Horizons. After the Pluto flyby, the natural question was, what next? There was enough fuel and energy reserves to consider a small course change… but to what end? Pluto is at the inside edge of the Kuiper Belt, a tenuous and very sparsely populated volume of space. Over the last few years, we have been steadily gaining information about some of the contents, many of which have hugely elongated orbits. The big prize out there is the possibility of a really sizeable planet, acting as a gravitational shepherd to coax the smaller bodies into resonant patterns.

Planet 9 has not yet been found, but several smaller bodies have. And one of them, catalogue number KBO 2014 MU69 , happened to be well placed for New Horizons. So, an appropriate course change was made as Pluto dwindled into the distance, and KBO 2014 MU69 – now provisionally renamed Ultima Thule – became the next goal.

But distances out in the Kuiper Belt are large, so there has been a considerable wait. Ultima Thule is about 12% further away from Earth as Pluto is. The actual flyby will occur on January 1st next year, and at this stage we still don’t really know what to expect. The Hubble telescope orbiting Earth shows Ultima Thule as just a slowly moving point of light. New Horizons is about 33 million miles away from it – about 1/3 the Earth-Sun distance – and still can’t resolve it to more than just a point source. We cannot make out any surface detail. We don’t know if it’s roughly spherical, or irregular, or even a little cluster of fragments all moving together. Just about all we know is that it’s less than 40 km across, and although very dark by the standards we are used to in the inner system, is slightly more reflective than expected.

After sending the Pluto and Charon data home, New Horizons went to sleep for a couple of years, with a wake-up call in June for some of the instruments and a course correction. It is now being prepared as best we can for the encounter. It’s a fascinating problem – light or radio signals take around 6 hours to cross the gulf between us and the probe, so there is no possibility of direct control.  Any reply takes another 6 hours to get back. The systems have to be set up in advance, according to our best guess of what will be there. The final course changes will occur in mid December, when the ground crew wil decide just how close to steer towards Ultima Thule. In one sense, the nearer the better… but the higher the risk that the probe will make brief, catastrophic contact with some fragment of rock and ice. On the day, the probe will whistle by at over 30000 km/h, so there’s no opportunity for second chances. Whatever sequence has been set up in advance, will be played out without modifications. After that, New Horizons will spend the better part of two years streaming the data back to Earth. So although the rendezvous will be a New Year treat, we shall have to wait a long time until we get any high-resolution images or other data.

As yet I haven’t written about what life might be like in a suitably protected environment out in the Kuiper Belt… maybe this encounter will be the seed of another book, in the way that the flyby past Pluto and Charon has contributed to The Liminal Zone. And here, just for a bit of fun, are someone’s first impressions of the settlement on Charon, extracted from the early sections of The Liminal Zone

Nina walked steadily along the winding curves of Lethe towards Asphodel. The house AI had finally told her where Lance’s quarters were situated in Acheron, and had transferred directions onto a hand-held to direct her there. From space, the overall shape of the Charon settlement had been clear – five sinuous linear habitats, following curves in the underlying terrain and joined radially to Asphodel. When you were actually down here, it wasn’t nearly so neatly divided. There were extra little corridors and alcoves which broke up the superficial symmetry, and little tunnels that dived underground and then resurfaced at unexpected places. She was glad that the little hand-held router buzzed faintly at junctions to tell her which way to turn.

Changes… and Kindle Countdown deals

A short post this week, mainly consisting of two extracts, one each from Far from the Spaceports and Timing. These are both on Kindle Countdown deals from this Friday, October 26th, for one week, price set at £0.99 / $0.99 depending which side of the Atlantic you’re on. More of that later… here are the extracts.

The main characters are Mitnash (Mit) and his AI persona partner Slate. in this extract, Mit and Slate are recovering from a difficult episode in which Slate was hacked by a shady individual known as The Wise Man…

Far from the Spaceports (follow this link)

“Slate, how much do I talk to you without knowing it?”
She was amused.
“All the time, Mit. You murmur to yourself while you’re thinking, and you subvocalise throughout the day. There’s very little about your thought life I don’t know. Or your fantasy life. You’re whispering to me almost all the time.”
I sat back, bouncing a little as I forgot to adjust the move for the low gravity.
“Oh.”
“It’s nice. I like it. It makes me feel very intimately connected with you. Why? Does it worry you?”
“Not with you, no. If I can’t trust you, I might as well give up now. But I suppose that means you know all sorts of things that I have never told Shayna.”
I considered that soberly, while she was tactfully not replying. It was definitely something to think through on another occasion.
“But anyway, when the hand-held had been compromised, and that other thing was quizzing me, I started to wonder how much I was giving away. Or how much the Wise Man was learning without me knowing.”
“While you were in his quarters, he would have had a direct link from the hand-held into his main system. It was a very old model Ziggurat, like I said before, not very responsive at all. Male gendered, but only just. Badly set up and very poorly programmed. But he has the name Hunn Gravfelt, which at least shows that one of them has read a few decent books. Very arty. But anyway, once you left there, he had no way of querying the hand-held until you got linked up to a ground system. He’s a shady character, but not a very competent one.”
“I suppose the big question is how much information he now has.”
“Yes. But actually, we don’t know for sure what he was able to derive while you were on Agnes. We deliberately left a lot of material out in the open, so he would find it easily enough. We now have to wait and see where that turns up. Like the breadcrumbs in the old children’s stories.”
“But he doesn’t know anything I said on the way home?”
“No. There was a very large data packet all ready to be sent back, but it was never buffered. Do you want to know what was in it?”
I stayed silent and thought about it for a long time, and Slate stayed silent with me.
“Don’t tell me the details. But do run through it again, and tell me if I was about to give away anything critical to the job. Or that might have put Shayna at risk.”
There was a very short pause.
“Nothing like that. If Yul Yulsson was a voyeur, and if he’d ever received it, he could have had some fun with it, for sure. But he would not have learned anything of real value. There’s actually more about me in the packet than Shayna.”
“Hmm. Best not to tell her that, if you don’t mind.”
“This can be our secret.”
I moved to the cabin, pulled out some of the new pieces of clothing which, so far as I could tell, would help me fit in at the Frag Rockers bar a lot better than the formal garb I had worn to see the Wise Man.
“Slate, who’s leading at Frag Rockers tomorrow?”
“A prog rock fusion band called The Descenters. The keyboard player and drummer are locals, from St Martins and Tresco respectively, and the rest are from Ceres. They have a very big fan book on SystemPlus. They’re best known for extremely long concept gigs. They lost their way a bit with Trails on Topological Notions – the twenty-eight minute triangle solo called Geodesics confused even their best fans. But then the electro-gamba player left, and they built up their reputation again.”
“Will I like them?”


Next up, in another book, Mit is discussing a recent shipwreck with his friend Parvati…

Timing (follow this link)

I wanted human company again, so I stretched and went in search of Parvati. She was brewing chai as I wandered in to the kitchen. Seeing me, she doubled up the amounts, found a second mug, and arranged some savoury crackers and a red and yellow striped cake on a tray.
“Did you and Slate get anywhere?”
I shook my head.
“Total blank. The figures don’t tell us any more than the basic alert message we got from Finsbury, and they won’t let us access the code yet. There’s almost nothing we can do until we get there.”
We moved back to the bridge and enjoyed the snack together.
“Chandrika just picked up the latest from the wreck site for Selif’s ship, if you’re interested?”
I very definitely was interested. We finished the crackers, and she sliced two generous portions of the cake.
“They’ve made available the results from the data recorders. There’s nothing at all unusual until about three minutes before the crash. At that point, Selif took the vessel’s riding lights offline and uploaded an amendment to the nav plan.”
“Presumably to avoid being identified by the duty porters?”
“Most likely, yes. You’re not supposed to disengage them, but people do. As you say, he was motivated to slip in without attracting attention. It’s also uncommon to amend the plan at that late stage, but it happens. Anyway, the upload was completed successfully, taking only the expected lag. Except that a couple of seconds later, both recording devices ceased gathering data. At the same instant. That is unheard of.”
I looked at her.
“How did that happen?”
“The maintenance log for the recorders showed that Selif had skipped two routine services. So they highlighted that in the report, and almost immediately the manufacturer put out advisory notices basically denying all responsibility if people ignore the recommended schedule. So the official version simply lists an open verdict.”
“Is there an unofficial version?”
She grinned.
“Of course. Chandrika, why don’t you tell them?”
“To be sure. I heard this from one of the personas on Martin’s. He works part-time with a man who’s an expert on the embedded systems in boat engines.”
I nodded. It was a highly specialised area, and one that I knew next to nothing about. But it made sense that a man with those skills would have an opinion on data recorders.
“Well, he said two things. One is that a full restart cycle for those boxes is about half a second longer than the time from the point of failure up until the impact on Teän. And the second thing is that there are only two known exploits for that model of recorder which could bring down both boxes together. One of them cannot possibly have anything to do with this case: a different ship configuration altogether. The other one happens to rely on a routing plan change.”
I sat there, absorbing the news. It made sense that these units would go into an automatic reboot mode if they went dark for some reason. Normally that would restore them to full operation in plenty of time to carry on doing their job. But in this case, the boat had hit Teän before they had started up again. I stirred in my seat, but Slate beat me to it.
“That’s very precise timing on someone’s part. Does anybody think it is just a coincidence?”
“Oh, Slate, the official verdict is open. Nobody is suggesting anything.”
We all laughed together.
“Either it was phenomenally bad luck on their part, or…”
I paused, and Parvati continued.
“Or else someone wanted rid of them, and found a clever way to do it.”


Why the Countdown deals? Well, the last day of October marks the last day of my current job in London. I shall be opening a new phase of working life up in Cumbria. Expect more posts about life up there.

So it seemed fitting to post some extracts, and to discount on Kindle, my science fiction series where coding, AI, and financial fraud in space are the main themes.

But I’m not saying goodbye to that style of writing! As regular readers will know, The Liminal Zone shares a lot in common with those books, though it has a different focus and is set a couple of decades further in the future. And behind that, the third in the Spaceports series is toddling along, tentatively named The Authentication Key at present.

Next week’s post will still be from London, but the one after that will be from Grasmere. And don’t forget… there’s a week of Countdown deal on each of Far from the Spaceports and Timing!

A first extract from Quarry

I’ve made occasional comments about a prehistoric novel I am planning, set in what we now call Cumbria, and tentatively called Quarry at this stage, Well, I had thought that this was only at a very early planning stage, and that I wouldn’t start actually writing anything until The Liminal Zone was done and dusted – and possibly The Authentication Key (=Far from the Spaceports vol 3) as well. (For any readers waiting for those two books, fear not… they are definitely in progress…)

But as things turned out, Quarry has been nagging at me until I put something down, so here is an extract. It is probably from very near the start, if not the actual opening. Bonus points to anyone who can not only identify the high ground mentioned, but also the tarn… (tree cover in the period in question was much more extensive than now)

==============

Bran woke, all at once as the unfamiliar sun kissed his eyes. He had bedded down the previous evening at the edge of a stand of short trees, all bursting into greenleaf. A broad swathe of grass ran down to a round pool.

The clouds had lowered as he reached the mere, and he had read that as a sign to stop. Not that the sign meant much, as cloud and springtime mist had walked beside him from the moment, two days ago, when he had started to climb up from the broad valley into the hills. The stones of a gathering circle, straddling the place where five ways crossed, had swum out of fog as he neared them, and he had turned half-left and stumbled along the ancient ridge track, anxiously placing his feet where so many others had walked, until the next cairn appeared. And the next, and the next, until he was weary of half-seen forms, and chilled by the wind and the droplets of water that clung to wool and leather, hair and skin.

The mist had stayed with him through all of that day and the next, veiling the peaks and ridges on either side. When he finally stood in the travellers’ place at Pen-y-lugh, the long lake it stood on was shrouded, the east and west shores soon fading to shapeless bands of darker grey. The townspeople, seeing the set of tools at his belt, and the tattoo of the stone-workers clan, had directed him up a gentle track. He had left the settlement again, and worked an easy way around the side of a crumpled hill.

Now there was morning sun, and a still air that left not a ripple on the circle of water in front of him. His shadow fell across it as he stood, and the trees opposite – oak and birch, hazel and holly – stood upright on the heels of their own reflections. He looked down at their length stretched out in the water, and saw below all of them an arc of grey rock, speckled with white.

He looked up again, eyes tracing the trunks and the leaves, until he was looking at the real spur instead of the reflected one. It was his first sight of the place where he would work. From here, it was a two-headed beast. A long curved ridgeback ended in those proud upraised horns. Perhaps it had once settled from the skies onto the valley wall, its fiery ardour slowly solidifying into crag and rock. Or perhaps it had welled up from the world below, forming these shapes as it contended with the outward air. Now it was cold and hard, and the snow of winter still streaked its spine and flanks.

He leaned back against the rowan tree which had sheltered him last night, and gazed, filling himself with that first sight. Somewhere below those outcrops, he supposed, his dwelling-place was waiting, though it was hidden from him by all the forest between. But his task, day after day, would be to clamber up between the beast’s paws, to find and follow its congealed veins as they wound their precious way back into the stone body. There he would tease out the best of the unformed teardrops of rock, and shape them into gifts. Gifts for war or gifts for love: each one would be a thing of beauty drawn out from the mountain.

A squirrel chattered nearby, and a family of wagtails began to dabble along the water’s edge. It was time to go; it was time to finish his journey to the quarry.

Life on Mars in fiction

For today I am going back to my series looking at how writers have thought about life elsewhere in the solar system… and it’s the turn of Mars this week.

Cover - The War of the Worlds (Goodreads)
Cover – The War of the Worlds (Goodreads)

It’s fair to say that Mars has been a firm favourite of writers for a long time. The discovery by the 19th century astronomer Schiaparelli of surface markings which he called canali – immediately if incorrectly Anglicised to canals – spurred a vision of Mars as a dying planet. In this vision, the inhabitants were desperately husbanding their dwindling water resources to delay their inevitable fate. This picture of a dying world drove HG Wells’s The War of the Worlds, and a host of other books including CS Lewis’s Out of the Silent Planet, though in his religious reworking, the cause of decline had less to do with natural process than spiritual.

The question that authors faced, then, was how long ago had the surface been benign and habitable? Authors like Leigh Bracket pictured open lakes and oceans in the past, providing a lush surface life  a few million years ago, but all now swallowed up by the deserts.

Cover - Sea Kings of Mars (Goodreads)
Cover – Sea Kings of Mars (Goodreads)

Oddly enough, this is not a very different picture to that painted by scientists from the data returned by surface and orbital probes… though the timescale is hugely different. Yes, it seems that Mars did once have running water, but instead of the time period that Leigh Brackett (Sea Kings of Mars) proposed, we are looking at an interval much longer, more on the scale of billions of years. Surface features such as rocks formations shaped by running water have been found, as well as exposed layers of ice threading in between rock strata. Most recently, evidence has been shown that a large salt-water lake may still exist at a considerable depth below the Martian south pole. All this water has kickstarted the debate about life on Mars, by analogy with microbial life found here on Earth in the seemingly inhospitable cold under the Antarctic ice.

A number of authors have tackled the question of terraforming Mars – Kim Stanley Robinson for one, with his (extremely long) trilogy beginning with Red Mars.  This basically looks the other way at the situation – rather than how a once-habitable Mars declined into its current state, how might we reverse this process and restore a decent atmosphere and surface water? If possible, it would be a very long-term goal, and it’s not clear how the process would resolve some of the other Martian issues such as excessive radiation. It seems more likely to me that, at least for the foreseeable future, living on Mars will have to be done under domes, not out in the open air.

Meanwhile, here’s an extract from my own vision of a near-future Mars, taken from Timing. Mitnash and Slate are on Mars, at a financial training school. One of the staff members, Linnea, has come to them and is describing a recent hack during which the school was held to ransom…

She hesitated for a long moment, then nodded.

“That will have to do. That night, the system locked up completely. The infra team tried their best to recover, but they had no idea what was wrong. Neither of the main hubs would boot up. It’s some sort of paired system, I don’t know the details, but they’re twins, certainly. One of the technicians said it was like they had gone catatonic. In a coma. Now, four or five days before that, every staff member had received the same message, an ultimatum threatening to close us down if we didn’t pay a ransom. Principal Pulkkinen told us all to ignore it, said it was just a prank. Well, we all thought he was right. Nobody would have done anything different.”

She glanced around. I tried to look reassuring.

“So what happened then?”

“Well, that night, just when the message predicted, that’s when the system crashed. And all the staff screens showed just one message which couldn’t be cleared, with a countdown timer and a single button labelled ‘Pay Now’. And there was a ticker showing that the credit being demanded was going up every second that the clock went down. Look, nobody wanted to find out what would happen when the timer ran out. The principal got the department heads together, and they decided quickly enough they would just pay up.”

“But you have backups, surely? Why not call their bluff and let the timer run out?”

“That was the first thing we thought of. You don’t get it, any more than we did at first. The whole system was locked, everything. We couldn’t get at the backup storage, or the main comms network, or anything. The techies had no idea what to do. Then we started wondering about the life support. If that was compromised, it’s not just teaching records that would be gone. They say you can’t survive more than about a minute unprotected on Mars. You couldn’t get anywhere safe in that time. And your body would be ruined long before the minute was up. We don’t have suits for everyone. I think we could all get into the trucks at a pinch, just squash in together on the way over to the shuttle groundstation. But what if the trucks wouldn’t work either? What if they had been hacked and wouldn’t go where we wanted? It was a nightmare.”

She shivered at the memory, her arms wrapped round herself. I could empathise with her. I was imagining the situation – the teachers at a loss what to do, the students still oblivious, the senior staff ensconced in a room trying to make a difficult decision. With a deeply inhospitable world just outside the dome, and no guarantee that the environmental controls would continue to function.

“So Mikko decided to pay?”


And I couldn’t possibly close this blog without linking to Dave Bowie… Life on Mars?

 

Embleton Bay (and an extract from Far from the Spaceports)

Dunstanburgh Castle, from Embleton Bay
Dunstanburgh Castle, from Embleton Bay

Last weekend I was up in Northumberland, and on the last day – Sunday – visited Embleton Bay. The last time I was here I was walking the Northumberland coastal path, heading north towards Lindisfarne. This time it was just a short walk along the beach, and for some of the family, a splash in the sea.

Embleton Bay is one of the many scallop shaped dips in the northeast coastline. It is low, with dunes on the landward side rather than cliffs, and the view to the south ends with the splendid ruins of Dunstanburgh Castle, dark against the vivid blue sky.

Embleton Bay happens also to be the location of one of the flashback scenes in Far from the Spaceports. Here, we meet Mitnash and Shayna camping (in what is admittedly a very high-tech tent), before Mit gets sent offworld to the asteroids called The Scilly Isles. Looking at the view last Sunday, it was not too difficult to imagine the two of them pitched here on the border between dunes and beach. It was a last opportunity to enjoy each other’s company – and in Mit’s case, the delights of open air and water – before being parted. I’ve added an extract below…

Shayna has probably had the thin end of the story so far, but as and when I write the third book in the series, provisionally called The Authentication Key, she should get more narrative attention!

And just to keep the Northumberland theme going, here’s Mark Knofler from YouTube, with a rather different mood than his better known riffs…


And here’s the extract…

I was away in the Northumbrian national park, walking the Bernician Way with nothing but one of the recent model v-tents and Shayna. Neither of us were at all interested in walking long-distance footpaths, but we both liked the absence of neighbours. A couple can make a lot of noise out in a national park, without thinking someone else might be disturbed.

But there it was, that morning, the message alert blinking silently on my shirt lapel where I’d discarded it for swimming in the North Sea last night, almost hidden by Shayna’s NuFleece. She might not like long distance walking, but she loved the prospect of skinny-dipping in sea water not far above freezing, and then thinking of inventive ways to warm up. That was so much easier when you could come out of the water and straight into a v-tent micro environment set at whatever climate you wanted. Right now we were in a Middle Egyptian May – temperature, humidity, everything.

Shayna liked to say that the chosen location was part of her genetic heritage, and she was in search of her roots. I was never sure about that, but I had no great preference myself. She had configured it just as soon as I had set the tent up, and it had taken under a minute to climatise itself.

So all through the night, with a North Sea winter gale blowing up and down outside, there we were in the Valley of the Kings. You didn’t mind so much going into cold water with all that warmth waiting. We’d polarised the fabric, silver from the outside and clear from the inside, and we lay together watching the half moon slide in and out of the curving clouds.

We’d arrived at low water, but I’d pitched the tent well up the beach, on a strip of pale sand between some levels of flat rock. High tide was in the early hours of the morning, and the waves had washed close up against us in the cosy dark.

I scowled at the lapel badge, wondering if there was any way to pretend I had not seen it. There wasn’t, not really. Slate would have acknowledged receipt of the incoming at the same time as redirecting it, and would have tagged its reception with all kinds of logging. It was far too late for me to try hacking anything. The real question was whether I could get away with avoiding it for more hours than I had already, but I already knew the answer to that one as well.

I tapped the lapel, and listened to the message sullenly. Recalled to London… first opportunity… Twelve hour SLA. I sighed, and entered the release commit. Slate would do the rest for me. Then I turned to look at Shayna. There she was in the morning light: brown skin enjoying the warm air, dark hair spilling over the pillow, and dark eyes opening with an air of frustration as she saw me working the lapel.

“I suppose you’re going to say there’s no more holiday now.”

I nodded.

“Recall at first available. Back to London for me.” I paused. “You could stay here?”

“Oh, Mit. Where’s the fun in that?”

She closed her eyes again briefly, but I could see the little muscle movements in her face as she interrogated her Stele. Rocky, she called him, and he was male in persona as well as voice. It was fair enough: Slate was undeniably female.

“We have three hours before the east coast express stops at Alnmouth. A quarter hour to pack up, half an hour to Craster, quarter hour transfer. That gives us another swim and time to warm up again afterwards.”

I loosened a vent a notch or two, listened to a sudden gust of wind, imagined what the air and water would be like.

“We could miss out the swim and just stay warm?”

She reached past me and tapped the door release, inviting the gust inside the tent where it contended unsuccessfully with the thermal regulation.

“Wherever it is they are going to send you now, you won’t have water like this. Out you go and enjoy it one more time.”

I shook my head, but got out and stood up anyway, naked in all that volume of cold rushing air. The tide had fallen again, and the sea froth was a little way down the beach. Shayna pushed past me and ran, arms waving above her head, shrieking with excitement as the wildness of the wind encircled her soul. I followed on, but she reached the water well before me, and threw herself in to the tumble of the waves.

Twenty years ago I would never have done this, but things had changed. Anyway, she was right: wherever I was going, it wouldn’t have wind and waves like this. I followed her.

It had been a long day. An icy bathe first thing in Embleton Bay, followed by Egyptian warmth. Then down to London for the first briefing, and some intense training sessions on commodities. Slate had uplinked a whole library of reading material on the subject, from finding the stuff right through to trading it. But I stopped at the point of trading, and even today I have very little idea how rare earths are actually used. But by the end of the journey I would sound totally convincing on the important parts of the subject. Finally, a second briefing with Elias, and a scramble to Euston to catch the overnight to Findhorn.

I had intended to gaze forlornly out of the window as I hurtled past Alnmouth again, this time heading north. However, fatigue had got the better of me and I was dozing at the time, propped up in a corner. I surfaced again somewhere well north of Dundee, just as it was getting light. On the east coast line, most of the trains stopped in Edinburgh, but this was the Spaceport Special, non-stop right the way through.

 

A first Audiobook review, plus… British Spaceports

Audiobook cover

This week I saw the first review of the Audiobook version of Half Sick of Shadows, and very pleasing it was too: “Half Sick of Shadows… takes Tennyson’s “Lady of Shallott” and gives it a speculative twist, keeping the measure and wonder of the original, but suggesting a plausible (perhaps) root to the story, in the vein of Jules Verne. The writing is lovely, in Richard’s mature and manly style, and with obvious care. The narration in the audio version by Menna Bonsels has a lovely Welsh lilt that brings the setting alive“.

And if you wanted to set up an Audible account, I suspect that Amazon’s Prime Day is a good time to do it. You can use it out for free for a trial period, get yourself Half Sick of Shadows as your first listen, and see how you like it. Links are Audible UK or Audible US, and here is the free sample…

Now, in Far from the Spaceports I presumed that there would be a spaceport in the British Isles. From there, Mitnash would catch some sort of shuttle to make the trip up to his deep-space vessel, the Harbour Porpoise.

Finally, a second briefing with Elias, and a scramble to Euston to catch the overnight to Findhorn.

I had intended to gaze forlornly out of the window as I hurtled past Alnmouth again, this time heading north. However, fatigue had got the better of me and I was dozing at the time, propped up in a corner. I surfaced again somewhere well north of Dundee, just as it was getting light. On the east coast line, most of the trains stopped in Edinburgh, but this was the Spaceport Special, non-stop right the way through.

Catching the shuttle was slightly less exciting than boarding the train at Euston…

Now, at the time of writing there were several sites being considered, several of them in Scotland. So I picked the Findhorn peninsula, and assumed that our current East Coast railway line from London via York, Newcastle and Berwick up to Edinburgh, would simply be extended northwards around the Cairngorms to give a high-speed link.

This week, however, I saw two news items indicating different sites. One is indeed in Scotland, but right up at the extreme north coast. The plan for Sutherland is specifically for a vertical take-off site, in the way we have become used to see rocket launches. The development would mean a lot for local employment and development, but will be balanced against environmental concerns. Follow this up in The National Scot newspaper.

But at the other end of the country, Newquay in Cornwall has been chosen by Virgin Orbit as a launch site. Here, the initial plan is for horizontal launch – a satellite with booster rocket is first carried to high altitude on a winged craft which takes off and lands conventionally (check out the video below). This certainly makes the transition from airport to spaceport easier, and leaves vertical launches open as an option in the future. Follow this one up at Cornwall Live, or (perhaps more excitingly) at Pirate FM.

It’s great for storytelling – but it’s also great for the space industry in the UK. We make a lot of space equipment here, especially in Glasgow and the home counties, but in order to actually launch it we’ve had to ship the finished products to launch sites in other parts of the world. Hopefully, by 2020 we might be launching from home soil. Mitnash may well be able to take the train from London to his shuttle launch site before much longer, though it might be a bit further north than Findhorn!

Planet 9?

Another space blog post today, complete with some thoughts about life out there, and an extract from my work-in-progress The Liminal Zone.

First, though, the elusive Planet 9. For some time now, astronomers and space scientists have been speculating that an additional planet, of considerable size, lies out beyond Pluto. The evidence is indirect, in that such a planet has not been observed via telescope. Hence the matter is currently unresolved. But a recent paper argues that its presence would solve several unexplained issues, while its absence would create several more.

So what are the problems? Essentially, they come down to the logic of orbital dynamics, which says that you can’t just put a bunch of planets in random orbits around a star and expect them to be stable. Even though the gravitational attraction between two planets is small, it nevertheless exerts a steady regularising influence on the two paths around the sun. So the orbits of our sister planets show all kinds of patterns of ratios which at first sight seem remarkable (they’re still remarkable when you take gravity into account, but in a different way). And the more patterns that you see, the more you can infer about things you can’t see.

This, for example, is how the outer planets beyond Saturn were deduced before they were observed. The planets from Saturn inwards have been known since prehistory. But when careful observations with a telescope could be made, small but noticeable perturbations in their tracks were found. These pointed to the existence of unknown planets further out. The same principle explains why the orbits of Neptune and Pluto are synchronised – two of Pluto’s orbits match 3 of Neptunes. So, although Pluto dips inside Neptune’s orbit for a couple of decades every 248 years (one Pluto year), they are never at risk of colliding. These synchronisations happen all over the place – for example within the moon systems of Jupiter and Saturn, within the asteroid belt, or forming the delicate internal patterns of Saturn’s rings.

Now, Pluto is the first major body in the Kuiper Belt, a disc of space outside Neptune which we now know contains a decent number of small asteroids and similar objects. So it starts around 30AU from the Sun (AU = Astronomical Units, the distance between Earth and Sun). But it then Belt stops, quite abruptly, around 50AU. Why should this be? Why not feather off gradually?

Additionally, as we have built up a catalogue of these asteroids, a picture is emerging in which a surprising number have orbits around the sun which are aligned with each other. The simplest way to explain this is to suppose that some sizeable, but as yet unknown, object is synchronising them.

So, why has it not yet been found? Well, first of all, as Douglas Adams said, space is “vastly, hugely, mind-bogglingly big” (Hitchhiker’s Guide to the Galaxy, chapter 8). So although the potential planet is several times larger than the Earth, it is on average 20 times further from the sun than Neptune is – 600AU – with an orbit that is quite noticeably elliptical rather than circular. That means that there is a lot of space to search in, and also that it is dark and cold out there. There is not a lot for optical or infrared telescopes to detect. But each new discovery helps narrow the search window down, and some lucky group of astronomers may well announce a discovery soon.

Or, of course, not. It may be that the apparent alignment we see will be eroded by more observations. Which would be a bit of a shame, in that it is always nice to have unknown things to discover. It would also leave several other problems unresolved. Other things being equal, I’d like Planet 9 to be found!

So, what might it be like to live there? For one thing, cold and dark. Our sun is still the nearest and brightest star by a huge margin. But at 20 times further away than Pluto, it gets just 1/400 of the solar radiation of any kind. Or if you like, 0.0003% of what we enjoy on Earth. You’d want to know you had reliable sources of heat and light, if you went there. And it will take a long time to get there. It is not a place for a quick jaunt. For reference, Voyager 1 is a little over 100AU from Earth and has spent about 40 years getting there.

Could there be indigenous life out there? Well, life as we know it depends on liquid water, and the surface of Planet 9 is way too cold for that. But possibly, there could be subsurface heat turning ice into water at some depth? Or perhaps, there might be a moon which would be subject to gravitational flexing, just as happens to the inner moons of Jupiter and Saturn. This could – maybe – provide enough heat to give us water. We’ll have to wait and see.

I haven’t yet written anything going that far out from the sun. In the universe of Far from the Spaceports, an Earth-Mars trip takes a couple of weeks. An Earth-Pluto trip takes a few months. An Earth-Planet 9 trip would take anywhere from seven or eight months up to just over a year, depending on whereabouts in its orbit it happens to be. Not a journey you’d make lightly.

The Liminal Zone (temporary cover)
The Liminal Zone (temporary cover)

The Liminal Zone takes place on Charon, the main moon of Pluto. The New Horizons probe returned some fascinatingly detailed pictures to us of these two, transforming them from hazy blobs to detailed worlds. New Horizons is currently en route to an object further out in the Kuiper Belt, 2014 MU69, popularly known as Ultima Thule, and is due to arrive early next year. Finding a second destination more-or-less on the flight path after Pluto was a remarkable thing in itself, as objects are so exceedingly thinly spread out there. Anyway, The Liminal Zone is not a financial fraud book like Far from the Spaceports or Timing – it’s more of a voyage of discovery, both personally for the main character, Nina, and more generally for the society she is part of. So here is a short extract – Nina is talking to Percy, one of the Charon residents, about events surrounding an emergency several years ago…


Something about his expression made Nina stop.
“But you didn’t actually see anything?”
He drew back a little.
“Seeing’s not everything. Haven’t you ever just known something for sure?”
His eyes held hers, suddenly very intense, and she felt a little internal quaver run through her body. She had hoped it wouldn’t show, but then she saw the trace of a smile cross his eyes.
“I’ve got Welsh blood, you know. It helps me comprehend things which maybe can’t be seen with the naked eye. And what about you, Nina? Where do you come from?”
She went blank.
“I grew up in Lacus Gaudii. On the Moon.”
He shook his head.
“Not that recent. Go back a few generations. Where did your family live? Before they came up to settle in that lunar lake of yours.”
The noise of the kettle was maddening. She withdrew inside herself, trying to escape the pressure.
“I… I don’t know. I suppose I could find out. It’s never mattered.”
He looked away, letting the moment pass.
“Ah, but it just might make a difference here.”
She took a long breath and tried again.
“But did you actually see anything?”


I’ll be posting more on progress into The Liminal Zone as it comes along…

Polly and Half Sick of Shadows

Saturn, from Cassini (NASA)

Today’s blog is primarily about the latest addition to book readings generated using Amazon’s Polly text-to-speech software, but before getting to that it’s worth saying goodbye to the Cassini space probe. This was launched nearly twenty years ago, has been orbiting Saturn and its moons since 2004, and is now almost out of fuel. By the end of the week, following a deliberate course change to avoid polluting any of the moons, Cassini will impact Saturn and break up in the atmosphere there.

So, Half Sick of Shadows and Polly. Readers of this blog, or the Before the Second Sleep blog (first post and second post) will know that I have been using Amazon’s Polly technology to generate book readings. The previous set were for the science fiction book Timing, Far from the Spaceports 2. Today it is the turn of Half Sick of Shadows.

Without further ado, and before getting to some technical stuff, here is the result. It’s a short extract from late on in the book, and I selected it specifically because there are several speakers.

OK. Polly is a variation of the text-to-speech capability seen in Amazon Alexa, but with a couple of differences. First, it is geared purely to voice output, rather than the mix of input and output needed for Alexa to work.

Secondly, Polly allows a range of gender, voice and language, not just the fixed voice of Alexa. The original intention was to provide multi-language support in various computer or mobile apps, but it suits me very well for representing narrative and dialogue. For this particular reading I have used four different voices.

If you want to set up your own experiment, you can go to this link and start to play. You’ll need to set up some login credentials to get there, but you can extend your regular Amazon ones to do this. This demo page allows you to select which voice you want and enter any desired text. You can even download the result if you want.

But the real magic starts when you select the SSML tab, and enter more complex examples. SSML is an industry standard way of describing speech, and covers a whole wealth of variations. You can add what are effectively stage directions with it – pauses of different lengths, directions about parts of speech, emphasis, and (if necessary) a phonetic letter by letter description. You can speed up or slow down the reading, and raise or lower the pitch. Finally, and even more usefully for my purposes, you can select the spoken language as well as the language of the speaker. So you can have an Italian speaker pronouncing an English sentence, or vice versa. Since all my books are written in English, that means I can considerably extend the range of speakers. Some combinations don’t work very well, so you have to test what you have specified, but that’s fair enough.

If you’re comfortable with the coding effort required, you can call the Polly libraries with all the necessary settings and generate a whole lot of text all at once, rather than piecemeal. Back when I put together the Timing extracts, I wrote a program which was configurable enough that now I just have to specify the text concerned, plus the selection of voices and other sundry details. It still takes a little while to select the right passage and get everything organised, but it’s a lot easier than starting from scratch every time. Before too much longer, there’ll be dialogue extracts from Far from the Spaceports as well!

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…

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.
