We have a strong, if mythic, assumption that humans will move into space and, eventually, hop through wormholes from galaxy to galaxy. That whole notion may evaporate if we dismantle the space station and end the practice of sending humans into space. MIT Technology Review discusses “The Future of Human Spaceflight”:
Over the years, NASA and space advocates have put forward many reasons to justify sending astronauts into space. They have garnered support by offering something for everybody, especially the military and scientific communities; scientific progress, strategic superiority, and international prestige have been foremost among the promised benefits. On closer inspection, though, these justifications don’t hold up or are no longer relevant. For example, robotic missions are increasingly capable of scientific work in space, and they cost far less than human crews. Satellites launched on expendable boosters allowed the United States to achieve strategic dominance in space. And Cold War motives disappeared with the collapse of the Soviet Union.
The article goes on to discuss how humans might continue to build into space, leveraging in-space refueling to reduce costs. I’ve tended to think that private commercial efforts will find innovative ways to make space travel workable and affordable. The vision is so strong with us now, via television and film (Star Trek, Firefly, Star Wars, Avatar, Spaceballs, etc.), that it seems unlikely we’ll put human space travel aside.

I literally grew up with David Levine’s caricatures; it never occurred to me that he was flesh and blood and would die someday. That day has come, and and like many, I’m mourning his death, who produced who knows how many hundreds of caricatures for The New York Review of Books and the New Yorker. The former publishes as a tribute John Updike’s note about the artist, written 30 years ago:
“Besides offering us the delight of recognition, his drawings comfort us, in an exacerbated and potentially desperate age, with the sense of a watching presence, an eye informed by an intelligence that has not panicked, a comic art ready to encapsulate the latest apparitions of publicity as well as those historical devils who haunt our unease. Levine is one of America’s assets. In a confusing time, he bears witness. In a shoddy time, he does good work.”
The Times has a slideshow of some of Levine’s color caricatures here.

Fen Montaigne has written a piece about penguins and climate change for the New Yorker. The magazine’s web site features a disturbing slide show about how the penguins are threatened by habitat change due to warming sufficient to melt arctic ice. Montaigne suggests habitat change will likely be global, affecting humans as well as penguins.
I’ve been thinking how politicization of climate change is making it hard to think about the problem, which is clearly real, and decide what action we should be taking.
My friend Emily Gertz was in Copenhagen; she’s reporting on it in a discussion at the WELL.

This is what you want to find under your Christmas tree – the hypercool Roadrunner trike, “designed to ride on the tarmac [and] that can carry up to 25kg of load.” It’s pedal-powered with a secondary electric motor rear wheel. [Link]

I should say more about the “Collapse” preview I just posted – don’t want to mislead. For every pile of ashes there’s a great squawking phoenix, after all.
In fact I can’t say that we’re not screwed – god knows what unforeseen dangers are lurking in our little corner of the universe. The sun could explode, or the planet could implode. The Yellowstone caldera is overdue for a cataclysmic eruption. All hell could break lose.
And if you’re conversant with Buddhist thinking, you know that all things are impermanent.
That said, I also know that we’re remarkably resilient and we can probably survive more than we know. The real question (as in the global warming controversies) is this: is there something we can do now to avert a catastrophe, and should we be doing it? Those who once denied “global warming” (I prefer climate change), faced with incontrovertible evidence that Something Is Up, are now acknowledging that point but arguing that there’s nothing we can do about it (i.e., we shouldn’t do anything to disturb tourism on Amity Island, even as Bruce the shark cruises the waters, looking for hors d’oeuvres.)
This is the way the world ends
This is the way the world ends
This is the way the world ends
Not with a bang but a whimper.
