Dawn will have to wait until September ...

... as stated in this press release. The other information in the previous post on this subject still holds good.

As I understand, there's no fallback period for launch after September-October: by the time Dawn would arrive in the asteroid belt following a late launch, Vesta and Ceres would be too far apart for the spacecraft to visit both of them. [I don't have an authoritative reference for that statement, but I may add one if I get time to look around online in the next week or so.] One hopes that they've cleared their slate in September, and that the weather holds.

ATLAS under construction

There are time-lapse movies of the ATLAS detector under construction on YouTube here, in one minute and two minute versions. They give a better idea of the sheer scale and complexity of the thing, than mere description does.

ATLAS, and the Large Hadron Collider project more generally, was discussed in an earlier post

Dawn is about to depart

The Dawn spacecraft will be launched on a mission to the asteroid belt in a few days. Check it out at the Dawn website.

Dawn will be the first spacecraft to orbit two separate bodies after leaving the earth. This is a rather difficult thing to do, and the craft can manage it using ion engines: their thrust is low but they are extremely efficient in their use of propellant (more technically: the specific impulse is very high). You leave them switched on more-or-less permanently, and after a few months you are either going like the clappers, or have climbed further out of the gravity well of the sun (or some other body) ... or both.

The targets of the Dawn mission are the two most massive asteroids, Vesta in 2011 and Ceres (now officially classified as a dwarf planet after the recent shakeup in naming) in 2015. These two are about as different as asteroids get, in their characteristics, and so if one is to choose only two targets, this pair is a good pick.

Good luck to the Dawn team ...

Rings Around Saturn

NASA's Cassini probe has been at Saturn for three years now, and the team have celebrated by putting together a slide show. Some of the captions are insufficiently detailed, but there's no quarrelling with the pictures.

(I could hope that this post will attract as many hits as the recent one whose topics included "HBO", "Mormons", and "sex" ... but it probably won't. A shame, that.)

Let's be honest

I just added "Christianity" to the official subtitle of this blog, as one of its prevailing concerns. Because, let's be honest: who was I kidding by omitting it?

The tendentious nature of much discussion on theo-blogs still dismays me: it sometimes dismays me when I'm engaged in such discussions. I would hope that my own contributions are reasonable, but this is for others to judge ... and it will not do to affect a distance from these discussions which is not supported by the data.

For the record, I have been known to contribute to the following theo-blogs, in roughly this order:

The Blogging Parson (Michael Jensen)

nothing new under the sun (Byron Smith)

hebel (Matt Moffitt)

Faith and Theology (Ben Myers)

My problem is usually with (some of) their interlocutors, rather than these gentlemen themselves.

The end of the affair

In tonight's episode of Big Love (on SBS) Bill Henrickson had an affair. With his wife. Which was an affair because he is a polygamist, with two other wives who had rights to him on the relevant days, as part of their agreed rotation. Except of course that they are not legally his wives, the Mormon church (and thus Utah) having ditched polygamy in the process of making peace with the rest of the United States. So was it still wrong?

Pretty clearly yes, but to say that without also making some comment about the Henrikson family's wider behaviour is plainly inadequate. The show's writers dramatise this by depicting Bill having the affair with his first wife, rediscovering the extent of his love for her through (get this) a display of her maturity and accomplishment at an official function. "Rejoice in the wife of your youth" says the Scripture (Proverbs 5; specifically verse 18, but context is everything) and that is exactly what Bill is doing. His exhilaration with his wife is the realisation of an ideal, too little matched in real life, and this is what makes the wrongness of his behaviour so hard to admit --- what makes it something to be admitted through gritted teeth. If the affair had been with the gorgeous, immature little third wife Margene, it would instead have been "natural" in a more depressing sense.

This is intelligent drama of a rather high order, the Mormons' moralising gripes about the program notwithstanding. (It's easy for me to say that, of course: it's not my ox that is being gored.) The situation is naturally dramatic; likewise the marginal nature of most of the characters, given the strong conventions within which they are living. Bill is an independent polygamist, rather than a member of an organised group, having been turfed out of the (fictitious) Juniper Creek compound as a teenager; first wife Barb is a regular Mormon by upbringing, and has been dragged semi-willing into this lifestyle after about 10 years of regular marriage; second wife Nikki is the daughter of the compound leader, and a true believer in this sense, but has acquired an uncontrolled taste for the wider world; and Margene by her background is a stranger to any kind of settled family life, and has been sucked into the family almost by accident. One of Bill and Barb's teenage children is old enough to have critically watched all of these events unfold, and is openly opposed to plural marriage. And so on ... it's even more complicated than that, but the complexities have been rather clearly dramatised. It's well executed, in addition to being well-conceived.

I cannot speak to whether the circumstances are in any way credible, even by television standards. I have only ever been acquainted with one Mormon; with no polygamists, to my knowledge; and with only one fan of polyamory (the current secular analogue), and that rather slightly. And as a Christian rather than a Mormon, it is not as if I have a dog in this fight. There was polygamy in the patriarchal period, of course --- that was how it was --- but the Jewish Scripture narrates it with one eyebrow firmly raised, and the Christian church has never felt the need to second-guess that judgement.

But this is yet another example of the new golden age of series television in which we live. Three cheers for HBO. And if I have to pick out anyone from the stellar cast (another notable feature of these times), it must be the exquisitely odd Chloë Sevigny, who seems to know no fear whatsoever. I would not choose to be locked in a room with her, but she deserves some kind of award for the nuance that she brings to her portrayal of Nikki.

(I cannot establish a stable URL for the official response to Big Love on the website of the Mormons, or [their own name for themselves] The Church of Jesus Christ of Latter-day Saints. But if you go to their website, click on "Newsroom" on the right-hand side, and then do a search on "Big Love", you'll find it.)

Grabowsky and McGann

Paul Grabowsky and Bernie McGann played at the Sound Lounge last night (and also Friday), in an ad hoc quartet filled out with two of the Waples brothers; both nights booked out, although last night they were also letting folk in on standing-room-only tickets ... I haven't seen the place so full.

The first set was good, but the second was outstanding. It was a particular pleasure to see McGann play: at 70, and as a legend, he has absolutely nothing to prove, and his performance reflected that.

Andy and Yelena: thanks for the idea, and for the company. A great night.

The love that dare not speak its name

There is a fascinating exchange on homosexuality and Christian (specifically Catholic) doctrine here, in a recent Commonweal magazine.

The correspondents are, if you can believe it, a straight male theology professor (Luke Timothy Johnson) who advocates acceptance of homosexual relationships, and a lesbian freelance journalist (Eve Tushnet), a recent convert to Catholicism, who stands for the traditional position of the church.

Despite what I initially thought, both of them seem to be on the level. And despite what you might think, both of them are worth reading.

Professor Johnson's responsibly liberal position involves a certain amount of --- let us be frank --- special pleading and tendentious argument. (The references to slavery, for example, are depressingly rote and tone-deaf. If that's not already clear to you, I suggest reading The Letter of Paul to Philemon and then trying to square it against Johnson's statement on the apostle's views.) But Johnson is an unlucky man. He indulges in much less special pleading or tendentious argument than you might expect, and he is clearly trying to be straightforward and plain-speaking. His concern for being faithful to Christian revelation, and faithful to the phenomena, is manifest. And he has put all of his cards on the table, including those which count against his own argument: a refreshing thing, that, in these polemical times. In isolation I would have called his contribution to the discussion a good one, for these and other reasons, but he has had the misfortune to be up against someone who completely outclasses him.

Ms Tushnet is altogether extraordinary. She is rigorous. She is open. She is clear on what is secure in her own understanding, and what is provisional. Honest and critical about her own experience, and speaking with what anyone in our culture would recognise as a kind of authority, she finds that she needs to listen to what Christian (and specifically Catholic) tradition has to say. Reading her words, I am reminded --- quite outside my own experience --- of why I take the Scripture seriously. Of why I take Christian doctrine seriously. This does not happen often.

Her position is a classic example of faith seeking understanding, the great model of Christian thought. Prof. Johnson by contrast is trying to achieve a final position --- to get in all the data --- and one feels the strain. In fairness to him, he will probably think the same thing in five years' time. Ms Tushnet may well think something quite different in five months' time, and as a scientist I can't help feeling that that is an indulgence. But I will still listen willingly to whatever she has to say.

-----

Stepping back from the detail of Prof. Johnson's and Ms Tushnet's positions, there is something deeply Catholic about their whole discussion. I mean that in a good way. It respects reason (and reasonableness), tradition, experience, insight, and beauty, in a way that many Protestant discussions do not. It takes difficulty and obscurity for granted. It is recognisably about a world that real people live in.

As an Anglican, I have the privilege admiring the (Roman) Catholic church from a safe distance. This is something worth doing, and something that my fellow evangelical Christians are depressingly reluctant to do. The Anglican Archbishop of Sydney, Dr Peter Jensen, is an honourable exception in this matter, and I note that it is a brave man who would accuse him of being insufficiently Protestant. So what, exactly, is everyone else's problem?

Pheasant Plucking

This afternoon on ABC Classic FM they played The Pheasant Plucking Song. If you're going to indulge in innuendo, you might as well go all-out ...

Cows With Guns (in claymation)

If you've never heard the comic classic Cows With Guns --- and there's a whole generation that seems not to know it --- there's a claymation adaption on YouTube with the original song as its soundtrack. Some of the claymation is a bit random, but still it's great to see/hear this song doing the rounds again in another medium.

In other claymation news, I only recently discovered the [adult swim] clip depicting What really happened after the Death Star blew up. Hysterically funny.

Back to Jupiter

There is now a proper website for Juno, the second in NASA's New Frontiers programme of medium-class, PI-led missions. NF is a good and necessary scheme: it fills the gap between the cheerful Discovery missions and the seriously expensive flagship efforts like Galileo and Cassini.

Juno seems like an intelligent, practical way to address the gaps in our knowledge of Jupiter: after the Sun, it's the dominant object in the Solar System, and it deserves a second orbiter. Juno is set to use a polar orbit, and a clever set of instruments, to complement Galileo's work and to further chip away at our ignorance.

In other planetary programme news, MESSENGER, on its way to Mercury, made its second flyby of Venus during this last week (one of many gravity assist manoeuvres to get it into Mercury orbit without breaking the bank). En passant it made some cooperative measurements with the ESA's Venus Express, currently in orbit around Earth's evil twin. It's good to see the inner solar system getting some attention as well.

Three cheers for the SES

The local branch of the New South Wales State Emergency Service spent the better part of Saturday at my place, together with a very big commercial crane, lifting a tree off the roof of my neighbours' townhouse. To be precise, the tree was leaning against the edge of the second-storey roof, having taken out a fence, the gutter, about ten tiles, and associated support beams. One metre further, and my neighbours' second bedroom would have been smashed open and under an inch of rainwater.

The SES generally has been busy in the last couple of days, with wild weather all along the coast and elsewhere. The rain is scheduled to last for at least another week, so there will be no rest for the wicked.

My last dealings with the SES were at a Cave Rescue Weekend more than fifteen years ago, in a late-adolescent flirtation (which would be surprising to some of my more recent friends) with the insanely dangerous pastime of recreational caving. In general, as a city boy, I don't have much cause to cross these guys' path, but I have always liked them. Even in this day and age, the work is voluntary. Respect.
