Twenty-​Ten

So, 2010 is here. We’re not quite at manned missions to Jupiter, yet, but NASA does have a few inter­esting missions planned. On a related note, I like io9’s 15 Reasons To Live For The Next 10 Years.

In other news, I’ve finally updated scribeoflight.org, which feels like a good start to the year.

The song of the day has been ‘Changes’:

I watch the ripples change their size,
but never leave the stream
of warm imper­man­ence and
so the days float through my eyes,
but still the days seem the same.
And these children that you spit on
as they try to change their worlds
are immune to your con­sulta­tions:
they’re quite aware of what they’re going through.

I have a feeling it’s going to be an inter­esting year.

Our Children, and Theirs

Kim Stanley Robinson, author of, amongst other things, the acclaimed RGB Mars trilogy, has written a powerful piece for The Wash­ington Post about the reasons for con­tinuing, or not con­tinuing, to explore outer space:

So why even talk about this? It is useful to take the long view from time to time. This is what science fiction does, and though science fiction has been bad about space, it has been good about time. Taking that long view, we no longer seem like the most soph­ist­ic­ated culture ever; indeed, much that we do now will look silly or even criminal in the future. The long view also reminds us that we are a species only about 100,000 years old, evolving on a planet where the average lifetime of a species is 10 million years. Unless we blow it, humans are going to be around in 1,000 years — and if we make it that far, it’s likely that we’ll last much longer than that.

So, what actions, taken today, will help our children, and theirs, and theirs? From that per­spective, decar­bon­izing our tech­no­logy and creating a sus­tain­able civil­iz­a­tion emerge as the over­riding goals of our age. If going into space helps achieve those goals, we should go; if going into space is pre­ma­ture, or falls into the category of “a good idea if Earth is healthy,” it should be put on the science fiction shelf, where I hope our des­cend­ants will be free to choose it if they want it.

An inter­view Robinson gave to SPACE.com around nine years ago touched on similar issues:

[Inter­viewer]: Why is Mars important? Or, more gen­er­ally, is space explor­a­tion important at all, when people are still starving down here?

[Kim Stanley Robinson]: No. Mars is not important, compared to people starving down here. It’s inter­esting, but in the his­tor­ical context you bring up, inter­esting is not enough. Same with space explor­a­tion. The Only Good Excuse for our focus on Mars and space more gen­er­ally, in this moment of history, is that we can learn things out there that can help us deal with the envir­on­mental crisis unfolding here on Earth. It has to be asserted that space science is an Earth science, and that like the other Earth sciences it is needed to help us get through the next couple cen­turies with less envir­on­mental damage than oth­er­wise would occur. But having asserted that, we need to make it so; to con­figure our efforts in space and on Mars toward that end.

I think we should go, want us to go; but I also know that we have a huge amount of work to do here first, that we have immense problems to deal with on this fragile planet. I wish there was a stronger desire both to go and to fix the problems.

Fine and Almost Like a Powder

When Buzz Aldrin first stepped onto the surface of the Moon he said: “Beau­tiful. Beau­tiful. Mag­ni­fi­cent des­ol­a­tion.” Here in 2009 those words remain as stirring and evoc­ative as they must have been back in 1969. We landed on another planet. Human beings walked on the Moon, walked on the object in the night sky that throughout mankind’s history had been omni­present but unreach­able. That was, and is, a big deal, a huge accom­plish­ment. I wish we were still walking on it, still seeing it, still exploring it. Cel­eb­rating the achieve­ment is neces­sary and important, is some­thing that should be done, if only to remind everyone that it really happened; but it would be far mightier, far bolder, to cel­eb­rate how far we went yes­terday by announ­cing how much further we are going to go today, to honour that epic journey of the past by launching ourselves yet further into the future.

And So We Came

It’s been a long time since I last read Kim Stanley Robinson’s trilogy of novels about Mars, but they are books I fre­quently find myself remem­bering, and mulling over, and wanting to read again. A month or so ago I managed to get hold of a copy of the first novel in the trilogy, and I’m looking forward to once again exploring Robinson’s world. Here is the opening of that first novel, Red Mars:

Mars was empty before we came. That’s not to say that nothing had ever happened. The planet had accreted, melted, roiled and cooled, leaving a surface scarred by enormous geo­lo­gical features: craters, canyons, vol­ca­noes. But all of that happened in mineral uncon­scious­ness, and unob­served. There were no witnesses-​except for us, looking from the planet next door, and that only in the last moment of its long history. We are all the con­scious­ness that Mars has ever had.

Now every­body knows the history of Mars in the human mind: how for all the gen­er­a­tions of pre­his­tory it was one of the chief lights in the sky, because of its redness and fluc­tu­ating intensity, and the way it stalled in its wan­dering course through the stars, and some­times even reversed dir­ec­tion. It seemed to be saying some­thing with all that. So perhaps it is not sur­prising that all the oldest names for Mars have a peculiar weight on the tongue-​Nirgal, Mangala, Auqakuh, Har­makhis– they sound as if they were even older than the ancient lan­guages we find them in, as if they were fossil words from the Ice Age or before. Yes, for thou sands of years Mars was a sacred power in human affairs; and its color made it a dan­gerous power, rep­res­enting blood, anger, war and the heart.

Then the first tele­scopes gave us a closer look, and we saw the little orange disk, with its white poles and dark patches spreading and shrinking as the long seasons passed. No improve­ment in the tech­no­logy of the tele­scope ever gave us much more than that; but the best Earth­bound images gave Lowell enough blurs to inspire a story, the story we all know, of a dying world and a heroic people, des­per­ately building canals to hold off the final deadly encroach­ment of the desert.

It was a great story. But then Mariner and Viking sent back their photos, and everything changed. Our know­ledge of Mars expanded by mag­nitudes, we lit­er­ally knew millions of times more about this planet than we had before. And there before us flew a new world, a world unsuspected.

It seemed, however, to be a world without life. People searched for signs of past or present Martian life, anything from microbes to the doomed canal-​builders, or even alien visitors. As you know, no evidence for any of these has ever been found. And so stories have nat­ur­ally blos­somed to fill the gap, just as in Lowell’s time, or in Homer’s, or in the caves or on the savannah-​stories of micro­fossils wrecked by our bio-​organisms, of ruins found in dust storms and then lost forever, of Big Man and all his adven­tures, of the elusive little red people, always glimpsed out of the corner of the eye. And all of these tales are told in an attempt to give Mars life, or to bring it to life. Because we are still those animals who survived the Ice Age, and looked up at the night sky in wonder, and told stories. And Mars has never ceased to be what it was to us from our very beginning-​a great sign, a great symbol, a great power.

And so we came here. It had been a power; now it became a place.

The Dimming of a Porch Light

Reading this made me happy:

NASA’s Kepler space­craft is ready to be moved to the launch pad today and will soon begin a journey to search for worlds that could poten­tially host life.

[…]

The mission will spend three and a half years sur­veying more than 100,000 sun-​like stars in the Cygnus-​Lyra region of our Milky Way galaxy. It is expected to find hundreds of planets the size of Earth and larger at various dis­tances from their stars. If Earth-​size planets are common in the hab­it­able zone, Kepler could find dozens; if those planets are rare, Kepler might find none.

In the end, the mission will be our first step toward answering a question posed by the ancient Greeks: are there other worlds like ours or are we alone?

[…]

If Kepler were to look down at a small town on Earth at night from space, it would be able to detect the dimming of a porch light as somebody passed in front,” said James Fanson, Kepler project manager at NASA’s Jet Propul­sion Labor­atory in Pasadena, Calif.

The original press release is on the NASA website, here, and you can find more inform­a­tion on the Kepler mission on Wiki­pedia, here, and also on the official website.

1.4 Earths

This is interesting:

The smallest planet around a normal star other than the Sun may be even smaller than first thought. A new analysis suggests the rocky body weighs just 1.4 Earths — less than half the original estimate. Obser­va­tions over the next few months should test the prediction.

[…]

If their analysis is con­firmed, it is an unclear whether the tiny planet could host any life. Because its host is a very dim red dwarf, the planet is likely to be frozen — even though it orbits at about the same distance as Venus from our Sun.

However, if the planet boasts a thick, insu­lating hydrogen atmo­sphere, it could sustain a hab­it­able surface tem­per­ature that might be able to support some life of some kind.

The star is about 3000 light years away, which sadly makes it a little inac­cess­ible; but we might be able to go there in the future.

Happy Birthday Spirit

According to APOD, NASA’s Mars Explor­a­tion Rovers are five years old this month. The image above was captured by Spirit, the first of the two rovers to land on the surface of Mars. I always get a buzz thinking about how there are two robotic vehicles wan­dering around an alien world.

A Dwarf Irregular Galaxy

The Astro­nomy Picture of the Day for the 29th of December is a marvel:

NGC 1569: Starburst in a Dwarf Irregular Galaxy, as featured in NASA's Astronomy Picture of the Day

Here is the caption from the APOD page:

Grand spiral galaxies often seem to get all the glory, flaunting their young, bright, blue star clusters in beau­tiful, sym­metric spiral arms. But small, irreg­ular galaxies form stars too. In fact, as pictured here, dwarf galaxy NGC 1569 is appar­ently under­going a burst of star forming activity, thought to have begun over 25 million years ago. The res­ulting tur­bu­lent envir­on­ment is fed by super­nova explo­sions as the cosmic det­on­a­tions spew out material and trigger further star form­a­tion. Two massive star clusters — youthful coun­ter­parts to globular star clusters in our own spiral Milky Way galaxy — are seen left of center in the gorgeous Hubble Space Tele­scope image. The above picture spans about 8,000 light-​years across NGC 1569. A mere 11 million light-​years distant, this rel­at­ively close star­burst galaxy offers astro­nomers an excel­lent oppor­tunity to study stellar pop­u­la­tions in rapidly evolving galaxies. NGC 1569 lies in the long-​necked con­stel­la­tion Cam­elo­pardalis.

Boldly Going

A still from J.J. Abrahms' much anticipated Star Trek film

I’m very easily pleased, most of the time; and if atmospherically-​lit space­craft are involved, I’m very easily pleased almost all of the time. The above still is from the forth­coming J. J. Abrahms-​helmed Star Trek remake, a film about which I’ll no doubt be writing more in the near future.

Here is the press release that accom­panied it:

Illus­trating the power of submillimetre-​wavelength astro­nomy, [the above] APEX image reveals how an expanding bubble of ionised gas about ten light-​years across is causing the sur­rounding material to collapse into dense clumps that are the birth­places of new stars. Sub­mil­li­metre light is the key to revealing some of the coldest material in the Universe, such as these cold, dense clouds.

Teun Hocks

An image of a man carrying groceries through space by Dutch photographer Teun Hocks.

I saw that image in an old copy of the Times Literary Sup­ple­ment I was flicking through this morning, and it is possibly one of the most arresting works of art I’ve seen in a long time. It was created (I’m hesitant to say “taken”) by Teun Hocks, a pho­to­grapher and painter about whom I can find very little inform­a­tion beyond a couple of lines on the Dutch Wiki­pedia, a small article on The Free Library, and this blurb for a mono­graph pub­lished by Aperture:

Per­former, pho­to­grapher, and painter, Teun Hocks plays the role of “an innocent Everyman in an always strange and often funny world,” as Janet Koplos recently noted. In scenes that range from bur­lesque to tra­gi­comic, his lonely Buster Keaton-​like persona per­severes through odd and unfor­giving envir­on­ments, strug­gling to find stable ground in an unstable, often absurd universe. Life’s com­plic­a­tions and chal­lenges take the form of impossible Rube Gold­ber­gian con­trap­tions fraught with psy­cho­lo­gical implic­a­tions. Each engaging image captures one moment of an implied nar­rative, trig­gering inev­it­able ques­tions about how the prot­ag­onist ever got himself into such a fix and what in the world will happen next. Teun Hocks starts by sketching various one-​man stories, then poses himself in a care­fully plotted setup against his own painted backdrop. After pho­to­graphing the scene, he paints in oil on top of the res­ulting oversize gelatin silver print. The wit, elab­orate tech­nique, and rich colors of his images combine to form an irre­press­ibly original oeuvre. In addition to his painted pho­to­graphs, the book includes drawings, Polar­oids, and studio shots, which illu­minate his creative process. Though Teun Hocks is widely known and shown around the world, this will be the first English-​language volume devoted to the artist.

Painting in oils on top of over­sized silver gelatin prints sounds like far, far too much fun.
