A Transect

Posted on 03:34 by Unknown
When I get stuck on a plot point or find myself typing instead of writing, a walk usually clears my head and gets me thinking again. This is one of my longer walks, more or less due south to the Thames.

Under A Double Star

Posted on 10:37 by Unknown


Into town today to talk for a couple of minutes on the BBC World Service about the recent discovery of a planet orbiting the Kepler-16 binary system. Both stars are smaller than the sun, one an orange K-type star, the other a red dwarf; the orbit of the planet, Kepler-16b, is similar to that of Venus; comparisons have been made to Star Wars' Tatooine (the hook on which so many news stories have been hung).  But Kepler-16b is about the size of Saturn, although with a higher density, suggesting that it possesses a core of ice or rock about half its diameter, enveloped in deep atmosphere at a chilly -100° C.  Not much chance for any carbon-based life like ours to see those double sunsets and sunrises, then, although it's possible that the planet's core might retain some heat and warm lower layers of its atmosphere, or that there might be a moon with an atmosphere that's both thick enough and with the right composition to generate a greenhouse effect.

Given that the Kepler spacecraft has discovered one planet around a stable binary star system, it's pretty likely that there are plenty more out there, and that some will be much more Earth-like than Kepler-16b. Perhaps there are even planets around triple-star systems; maybe even a planet or two orbiting a system with six suns, as in Isaac Asimov's short story 'Nightfall', where night is a rare and frightening event . . .

Well, it's nice to know that there are real-life equivalents of science-fictional scenarios.  Even better, we're beginning to understand that the universe is stranger than we can imagine.  Kepler-16b isn't the first explanet to be discovered orbiting a binary system.  There are two planets bigger than Jupiter orbiting the eclipsing binary NN Serpentis, 1700 light years away.  The stars, a red dwarf and a white dwarf, are believed to be a cataclysmic variable system, with the material drawn off from the red dwarf forming an accretion disc around the white dwarf.  When material from the disc falls on to the white dwarf, it triggers nuclear fusion and a cataclysmic outburst.  If enough material falls on to the white dwarf it could increase the interior density of the white dwarf, ignite runaway carbon fusion, and trigger a supernova. Imagine the view from a moon of one of those gas giants if that happens . . .

O Superman

Posted on 00:38 by Unknown
‘In good times magicians are laughed at. They're a luxury of the spoiled wealthy few. But in bad times people sell their souls for magic cures and buy perpetual-motion machines to power their war rockets.’

Fritz Leiber, ‘Poor Superman’

On Mars

Posted on 01:26 by Unknown
Found in PC World magazine during research:
"Probably the most special day I've had as a rover [driver] was the day I built my first drive solo on Mars," [Ashley] Stroupe said. "We were on the plateau on Husband Hill, and we were driving along the edge to get imagery of the valley below. I parked us right on the edge and got a spectacular view."

"I remember looking at those tracks and realizing what they meant -- my first tracks on Mars, and the first tracks actually made by a woman driving on another planet," she said. "I am proud of it every time I see that panorama from the very top looking down at those tracks."
It's an especially powerful piece of empathy or projection because driving a rover is more like one of those ancient text-based computer games than Gran Turismo or Second Life.  The Mars rover team at JPL keep in contact with their machine viaNASA's Deep Space Network, and because their time on the network is limited and the round-trip for signals between Earth and Mars takes between 8 and 42 minutes, driving by direct law isn't possible. Instead, while the rover rests during the Martian night, its team of drivers and scientists plan out the next day's moves, code them, and test and retest them before uploading them. The rover then executes those moves the next day. Yet note how by the second sentence of Stroupe's description, the pronoun has changed from I to we.   Identification is complete. "We were on the plateau on Husband Hill..." We were on Mars...

Cover Me

Posted on 09:44 by Unknown


Hey, here's the cover for In The Mouth of the Whale.  It's by Sidonie Beresford-Browne, and I like it a lot. There's a lot going on in the novel, but quite a bit of it involves spaceships (I know they have wings: they're on their way down into the atmosphere) and chunky worldlets and a gas giant.

The Hippity-Hop Theory of Writing

Posted on 01:03 by Unknown
"Because I don’t work with an outline, writing a story is like crossing a stream, now I’m on this rock, now I’m on this rock, now I’m on this rock."

Snark Hunting

Posted on 04:58 by Unknown
I was away - a short break in Bruges.  Lovely, thanks.  And now I'm busy with the copy edit of In The Mouth of the Whale, dealing with queries and corrections raised by a fantastically sharp-eyed editor with a good and solidly old-fashioned (in the best sense of the world) grounding in grammar who has not only read every word and noted every punctuation mark of the MS, but has queried the correctness and value of each and every one too. It's the first time I've done this kind of thing entirely on screen.  For every other novel and story of mine, I transferred marks made on a printed MS to an electronic file; this time, I'm hunting for overstrikes and red-lined corrections with the help of the search-and-replace function, and recalling a little of the performance anxiety I felt when I transferred from typewriter to word processor. But I get to read the whole thing again, this time in physical form, when the proofs are delivered, and the thing moves another step closer to actuality.
