The Cassini space probe has entered the “Saturn planetary system” — the zone in which Saturn’s enormous field of gravity is so huge that it becomes a mini solar system, with a gazillion of its own moons. Scientists are most interested in the huge moon Titan, and NASA Cassini imaging expert Carolyn Porco has written a short essay describing Titan.
I kind of cracked up when I read it, because it’s superb example of a genre I like to call “astronomer travel literature”: Floridly metaphoric evocations of extraterrestrial destinations, which feel as though they’d been excerpted from a Fodor’s travel guide in the 23rd century:
Patchy methane clouds float several miles above the icy ground. In places, large, slow-moving droplets of methane mixed with other liquid organics fall to the surface in cold but gentle rains, cutting gullies, forming rivers and cataracts, carving canyons, and filling basins, craters and other surface depressions. Imagine Lake Michigan brimming with paint thinner.
Above the methane clouds and rain lies two hundred kilometers worth of globe-enveloping red smog, making the Titan nights starless and the days eerie dark, where high noon is as dim as deep Earth twilight. Over eons, smog particles have drifted downwards, growing as they fell, to coat the surface in a blanket of organic matter. On high, steep slopes, methane rains have washed away this sludge, revealing the bright bedrock of ice. Could Xanadu, the brightest feature on Titan, be a high, methane-washed, mountain range of ice?
Man alive, they actually call that outcropping “Xanadu”. I love NASA nerds.

From an interview with ethnobotanist and anthropologist Wade Davis:
One of the cultures you celebrate in Light at the Edge of the World is the Inuit. What do you most admire about them?
Davis: The Inuit didn’t fear the cold; they took advantage of it. During the 1950s the Canadian government forced the Inuit into settlements. A family from Arctic Bay told me this fantastic story of their grandfather who refused to go. The family, fearful for his life, took away all of his tools and all of his implements, thinking that would force him into the settlement. But instead, he just slipped out of an igloo on a cold Arctic night, pulled down his caribou and sealskin trousers, and defecated into his hand. As the feces began to freeze, he shaped it into the form of an implement. And when the blade started to take shape, he put a spray of saliva along the leading edge to sharpen it. That’s when what they call the “shit knife” took form. He used it to butcher a dog. Skinned the dog with it. Improvised a sled with the dog’s rib cage, and then, using the skin, he harnessed up an adjacent living dog. He put the shit knife in his belt and disappeared into the night.

“Video from a camp north of Toronto in December 2005 shows a car spinning around in a nearby, snow-covered parking lot. Prosecutors characterized that as special driver training but the defense, and many outsiders, said it was nothing more than “cutting doughnuts,” a favorite winter pastime of young Canadian motorists.” - A key piece of evidence submitted in the trial of a gang of alleged young Canadian terrorists.
