Mother of All Bombs! I love that it's got an American flag on the nose. I really, really hope that one of the ISIS guys looked up and saw that American flag at the last second. :D

I honestly thought we'd used a couple of these before during the second Iraq War. I distinctly recall reading a story about a huge bomb going off in the distance, and the journalists initially thought that it was a tactical nuke.

All the news outlets are falling all over themselves to characterize this as the "biggest conventional bomb ever used", but it really isn't. The British "Grand Slam" bomb that was used against the Nazis was slightly larger, although probably not as powerful, since it had to penetrate the ground before exploding, hence had a lot of steel in it.

A nice discussion of why the MOAB explodes just above ground level.

More evidence for the self-awareness of elephants. If we're willing to do completely insane stuff like granting personhood to rivers, why on earth do we still tolerate the abuse and exploitation of elephants, dolphins and apes?

Elephants comfort distressed friends. I've seen something similar with crows. I was watching a family group foraging. They had the usual lookout perched on a lamp post, and then three or four adults and two juveniles working their way through the grass in a loose line abreast. One of the juveniles had something happen - I think possibly stung by a bee. He screeched in distress, and everyone immediately came swarmng over to protect him, even the lookout.

There was a lot of confusion and vocalization, and one of the adults flew back up to take the lookout post (I'm not sure if it was the same one or not), while the rest kind of calmed and reassured the juvenile. After about a minute of that, they spread back out into the forage line again. The juvenile gave a little forlorn squawk and just stood in place as they moved off. I think he was afraid that it was going to happen again. One adult came back and then walked right beside him as they continued searching for food.

When you see stuff like this, it's just so very, very obvious that their emotional life isn't that very different from our own, and that to at least some degree they're reasoning about possibilities based on an internal model of the world. I have very little patience with the type of ethologist who attributes all animal behaviour to instinct.

If I'm reading between the lines correctly, then the two people who are going to ride a SpaceX Dragon around the moon next year are going alone - without a pilot. The capsule is going to be controlled from the ground. Even by my own cold-war era standards of acceptable risk, that seems to be tempting fate just a bit.

Admittedly, they're only going once-around, with no lunar orbit, hence no insertion or second transfer burn, and the capsule is a sane ballistic re-entry design, without wings. There's got to be a transfer burn to leave earth orbit, though, and one expects mid-course corrections out and back. Having a manual backup would be nice.

All that being said, had I the money, and my health allowed, I'd ride it, and too bad if I got killed.


Edit: And I absolutely love SpaceX's attitude in this! They're gonna fly the Falcon Heavy for the first time this summer. They're gonna fly the Crew Dragon for the first time this November. And then, in 2018, they're going to start sending people to the moon. That's the way to do it. That's the way that NASA (and America in general) used to do.

What a wonderful day! Once again, after 40 years, America has a sanely-designed, modular spaceship with ballistic re-entry capsules. I'm glad I lived to see this day.

Satisfyingly fiery ignition and liftoff, amazingly so for a hydrogen burner. Nothing will ever again look so cool as Chrysler's kerosene burners from the Saturn rockets ("like Niagara Falls on fire" is the comparison that sticks in my mind) but these are fun to watch.

It's amazing to me that one can now watch streaming video from the spaceship during the launch. That's being uplinked through TDRS, apparently, which is why it only starts as the rocket is leaving the atmophere. Lots of little bits of flaming and sparkly debris falling out the back as it flies. One hopes that's normal. During the initial boost I saw two glowing chunks of something being kicked out of the exhaust (refractory coating from the nozzle, if I had to guess), and then later, during throttledown just before MECO, all kinds of glittery crap went spraying out of the back of the rocket, perhaps ice or something. You get to see the aerodynamic shroud panels from the SM peel apart and tumble away to stern, which is the kind of thing that one used to only see animations of.

I'm struck by how nearly the shrouded capsule with its first and second stage resembles a Soyuz. A lot of that is in the escape tower design and shrouding, I think. The whole thing's all smoothly covered over like the Russians do, instead of the lattice-work that we used to always use.

And, http://en.wikipedia.org/wiki/RS-68 reveals that the engine bell has an ablative coating which burns away during flight, which accounts for the aesthetically pleasing orange fire of the exhaust, and also for the glowing chunks that I saw.

It has been a really good past few months for space, even with the Virgin One disaster, and the Antares explosion, and the little comet lander tipping over. One has the comforting sense that we're moving toward Mars and the outer solar system once again.

Australian embassies will no longer help their citizens abroad pay their prostitution bills, it seems:

[...] Among the other examples offered by officials was the case of a man who approached the Australian embassy in Bangkok and asked for a loan to help pay for a Thai prostitute.

Such requests are common at that embassy, said Anita Downey, a senior official at Australia's Department of Foreign Affairs and Trade[...]


Most of these requests I can hardly imagine someone making with a straight face. The one I did feel was reasonable was a request to help get a polecat off the roof. That seems to me one of the "local knowledge" problems one might reasonably request consular assistance with, at least to the extent of getting advice about who to call, etc.

Philae

By any reasonable standard, Philae was a success, having gotten pretty much what it came for. I'll confess to being disappointed myself, though. I wanted more pictures. I most especially wanted to see what it looked like when it was at perihelion, and the comet was erupting. Realistically, it would have to be screwed into the surface to remain stable during that, I'm sure.

I'm hoping it will come back online later, as it gets closer to the sun, and gets more light.
rain_gryphon: (Default)
It has been a day of wonders! When I awoke this morning, little did I suspect that I would hear the comet singing its song - https://soundcloud.com/esaops/a-singing-comet .

I've also learned today of the existence of active asteroids - http://www.astronomy.com/news/2014/11/tail-discovered-on-long-known-asteroid .

Most amazing to me, though, is the fact that vascular plants apparently use mycorrhizae to share nutrients, hormones, and possibly information. http://www.bbc.com/earth/story/20141111-plants-have-a-hidden-internet .

This is the sort of thing that I would never have expected in a hundred years, and yet here it is, going on all around me. I've known all my life that you can't dig a hole in decent soil without finding mycelia, but I never once suspected that they might be doing more than just mindlessly breaking down compost. There is so much around us of which we are unaware.

Antares

Okay, the Antares was apparently using rebuilt Russian motors from their humongous moon rocket that used to explode every time they tried to test it. I'll have to reconsider my comment of http://xolo.livejournal.com/413820.html .

I'm going to go out on a limb and make my guess, from the video, that the oxygen pump/precombustor either burned through or else seized up and shattered. That was always the weak spot on that design, and the rocket looked to me to be thrusting for at least a moment after the explosion, so I don't think the combustion chamber exploded.

Anyway, damn.


Edit: As of Nov 10th, "turbopump failure" is the suspected cause. http://www.spacenews.com/article/launch-report/42502turbopump-in-aj-26-engine-implicated-in-antares-failure

An asteroid with rings. Who would've suspected that? When I was a little Xolo, only Saturn had rings.

They're theorizing that it has to have (so far undetected) shepherd moons as well, to have well-formed rings. On the other hoof, nobody thought something that small could have rings to begin with, so...

Many years ago, when it first came out, I read a novel called "Magic's Pawn", by Mercedes Lackey. It was popular, it had very good reviews in the fantasy and SF magazines, and, remarkably, it was about a gay teenager in love with his talking horse, with lots of vengeance, and tears, and star-crossed lovers, something like a YA version of Narnia. It ought to have been a huge hit, but for some reason it didn't work for me. Not just "didn't work", but I actively despised it, and avoided Mercedes Lackey books for many years in consequence.

So, anyway, for some time now, I'd been aware of 'Skandranon' as a popular Gryphon name, but hadn't known whence it came. Thus it was that while looking for Gryphon stories to read to fuel my recent Gryphon obsession, I came across a review of Lackey's "The Black Gryphon". I read it. I'm floored.

It's kind of like a Harlequin Romance with lots of violence and emotionally-needy Gryphons. It manages to press pretty much every button I've got. This could have been written to order for me. It's superficial, and over-wrought, and emotionally manipulative, and kind of fanfic-like, and I fell completely in love with it! (I'm not a devotee of Serious Literature, for those keeping score.)

I need to go back now and see what was the deal with "Magic's Pawn", I suppose.

The Canadian train disaster has followed a very old-fashioned news arc here, with initial stories on Saturday telling merely that a train had caught fire and derailed, and one person was dead, to stories today of the town centre being obliterated, and maybe 50 or 60 dead, once they find all the bodies.

News stories used to develop like that. Some apparently minor thing would just get larger and larger over a few days' time. I remember as a child, when you had the papers and news magazines to rely on, always making mental note of those one-paragraph bits about volcanic eruptions, revolutions, earthquakes, etc, in some far-flung part of the world, since they would usually generate detailed followups in the next few days papers, and then 'Time' would have pictures.

What's weird here is that this happened in Canada, and not off in the extreme north or anything, but right by Montreal. I haven't a clue why news was so slow to disseminate.

It's good that we're claiming portions of the moon as US territory, albeit belatedly. I cringed at the 'for all mankind' speech they had Armstrong give, however in consonance with the zeitgeist it was. I think to this day that had we landed, stuck in our flag, and promptly claimed the moon as American property, there'd prolly be a half-dozen different countries with moonbases there today.

So... Yesterday, I was feeling envious of the Hindus because they got to have a religious/cultural observance that only happens every 144 years. This morning I woke up to learn that here in the West, we're about to have a living ex-Pope, which hasn't happened in 600 years! America wasn't discovered the last time this took place, which amazes me.

The poor guy really does look like he's going to topple over dead any minute, but then again he's looked that way pretty much the entire time he's been Pope. The uncharitable might suspect that was a factor in his election, was that the Cardinals wanted a short-term Pope.

Of the four previous Popes who've resigned their office, two have been Benedicts, so it's not a name with an auspicious track record.

Now comes Peter the Roman!

Looking at the Indians travelling to and from their festival, I'm struck by the lovely colours of the clothing. There's less variety of colour than you'd see in an American crowd, but perhaps for that reason, it tends to harmonize very well. It's very much flowers and earth-tones.

I'm watching an Atlas/Centaur launch process from Vandenburg this morning, which is entertaining. I miss the cool-looking vernier engines that the original series Atlas used to have, though.

They bought the main engines for this from the Russians. How the world has changed!

It's apparently a type of cluster engine, a variant on that weird Russian practice of having one huge pair of turbopumps that feed multiple combustion chambers. That's apparently evolved into a stable, trusted method.

Okay... I used to earn my bread as a polymer chemist. Yesterday, I gave brief advice about lab equipment and procedures to a friend who's writing a science fiction story. I did that on Twitter. Today I find that I have a new follower: @MSNoisenclosure MS NOISE™ is focused on acoustic insulation in laboratories. NEW noise reduction enclosures for your vacuum pumps, water chillers, water coolers, compressors... I'm guessing there's some way to scan the aggregate traffic of Twitter (which must be immense) for keywords, or else you can buy that service from Twitter. Either way, it's kind of creepy...

They're testing one of the old Apollo F1s! Admittedly, only the secondary system that runs the turbopumps for the actual engine*, but still, it gushes turbulent, smoky orange fire in a way that modern engines just don't.

Paris, 1914. A collection of very early colour photographs of Paris. Most are from the period of the General European War, although there are some as early as 1909, and as late as 1937. My old dreamscape the Rue du Faubourge Ste. Denis has a spectacular picture here. Stuff like this amazes me. You can see this, and know exactly how that one moment in time looked a hundred years ago.

I love the pictures of places at night, lit up with coloured lights! There's a considerable increase in extravagance from the 1910s to the 1930s.

It's been 40 years since Apollo 8. I remember that night. We had a live Christmas tree, a big sprawling one, spare and open, with lots of room between the branches to hang ornaments. We used C7 lights. I remember in particular an odd, pink Westinghouse bulb that I still have. I moved it to the front and centre of the tree, so that I could admire it. They were a limited run, and rare even then. The tree was draped with mylar icicles, and a motley collection of ornaments that dated back to the 1880s. To the left of the tree stood the TV, and I sat on the floor (the grownups used the couch) and listened to the astronauts reading Genesis from lunar orbit. It's hard sometimes to believe those days ever really happened.
