Space is big

It’s hard to believe how far we are from anything else created by humankind. Except for our own, now-derelict third stage, nothing made by people or from the Earth — nothing — is within more than a billion miles of New Horizons.

From the latest news update of the New Horizons Project, NASA’s attempt to reach Pluto and the Kuiper Belt. The latter being the belt of Pluto sized planetoids at the edge of the classical Solar System. It’s some 30 to 55 Astronomical Units away; one AU being the distance from the Sun to the Earth, or about eight light minutes, or some 8 x 60 x 300,000 kilometres. Space is big, as Douglas Adams already noticed.

Space is not just big in distances, but also in time:

But you won’t have to wait another three years for our next significant distance and flight-time milestones — they come next year, when we cross the halfway point! But whenever quoting such milestones, I have to be careful about the meaning. So when will our spacecraft be halfway to Pluto? Well, that depends on which halfway you mean. (No, I am not kidding.)

  • If one asks, when have we traveled half the flight time to reach Pluto? That halfway milestone occurs on October 17, 2010.
  • But if one asks, when will we be half as far from the Sun as Pluto will be at the time of our encounter on July 14, 2015? That occurs somewhat earlier, on April 20, 2010.
  • And if one asks, when will we have traveled half the heliocentric distance to Pluto from our launch at Earth? That milestone occurs even earlier, on February 25, 2010.

So, as you can see, the answer to the halfway question depends on precisely what it means to be halfway. In fact, you could even ask when the halfway day was from New Horizons project inception on December 20, 2000, to Pluto arrival on July 14, 2015 — that was April 4, 2008. Or one could ask about the halfway day from when we began our push for a Pluto mission on May 4, 1989 (when we had our first meeting with NASA officials) until Pluto encounter — that was on June 9, 2002. So in some ways we’re already halfway there, and in other ways, we have well over a year to go to reach the halfway point.

In other words, any big deep space mission consumes a significant chunk of somebody’s career. Sure, a trip to Pluto is an extreme example, but even missions to our planetary neighbours like Mars or Venus require years of planning, preparation and monitoring.

Science fiction is too often impatient with these distances, zooming around the Galaxy through Hyperspace or Warp speed or whatever. It’s all so easy that real life space travel just seems unnecesarilly complex and difficult. Now I like a good space opera as much as the next guy, but I would like to see more attention paid to our own Solar System, because it is vastly more complex and big as Golden Age Science Fiction ever suspected. Surely it must be possible to write a good, exciting novel taking into account the realities of space travel rather than resorting yet again to shortcuts?

(Paul McAuley, from whose blog I plucked this link, has done his bit with The Quiet War, which makes full use of the latest research results on what our solar system actually looks like.)

Marsh rips Bono a new one

Bono has always been a smug wanker whose simplistic view of world problems does more harm than good, so it’s nice to see Dave Marsh ripping him a new one:

Maybe he doesn’t want to deal on the spot with descriptions of his repeated appearances at the conferences of the leading capitalist nations where he’s yet to ask his first hard question about anything but Africa; about his settling for promises from world leaders that patently weren’t going to be kept, and never doing more than mewing when they weren’t; about why it is that Zambian economist Dambisa Moyo, by no means an anti-capitalist, observes that she met him “at a party to raise money for Africans, and there were no Africans in the room, except for me,” or why so many other Africans have complained that he claims to speak for them but has never so much as asked their permission.

TMWRNJ!

funny, posts interesting only to me, video

Why did nobody tell me that Stewart Lee and Richard Herring, the Mitchell and Webb of the nineties, have uploaded all their old Fist of Fun and This Morning With Richard, Not Judy shows to Google Video? You can find them all convienently at Stewart Lee’s website.

Don’t forget to watch his latest show, Stewart Lee’s Comedy Vehicle, tomorrow on BBC2. The first two epsiodes have already been broadcasted and it may have been my imagination, but at certain points it looked as if he was waiting for Richard Herring to jump in, at least in his head…

Sounds familiar?

George Eliot on Silly Novels by Lady Novelists, as written in 1856:

The heroine is usually an heiress, probably a peeress in her own right, with perhaps a vicious baronet, an amiable duke, and an irresistible younger son of a marquis as lovers in the foreground, a clergyman and a poet sighing for her in the middle distance, and a crowd of undefined adorers dimly indicated beyond. Her eyes and her wit are both dazzling; her nose and her morals are alike free from any tendency to irregularity; she has a superb contralto and a superb intellect; she is perfectly well-dressed and perfectly religious; she dances like a sylph, and reads the Bible in the original tongues. Or it may be that the heroine is not an heiress — that rank and wealth are the only things in which she is deficient; but she infallibly gets into high society, she has the triumph of refusing many matches and securing the best, and she wears some family jewels or other as a sort of crown of righteousness at the end. Rakish men either bite their lips in impotent confusion at her repartees, or are touched to penitence by her reproofs, which, on appropriate occasions, rise to a lofty strain of rhetoric; indeed, there is a general propensity in her to make speeches, and to rhapsodize at some length when she retires to her bedroom. In her recorded conversations she is amazingly eloquent, and in her unrecorded conversations, amazingly witty. She is under stood to have a depth of insight that looks through and through the shallow theories of philosophers, and her superior instincts are a sort of dial by which men have only to set their clocks and watches, and all will go well.
