SpaceX searches for its 'grassy knoll' of possible Falcon rocket sabotage

Rustident Spaceniak
Boffin

Those sounds prior to the explosion

Close your eyes and just listen to the tape of the explosion, from the screeching sound to the big bang.

What it sounds like exactly is something gets loose near the top of the strongback, drops down inside there - hitting the structure (and possibly Ox tubing) a few times - then lands on the launch pad. Unfortunately for SpaceX, it seems they didn't have many sensors outside of the rocket to find out what it was. But I'd take a good look at the debris down there and search for something that looks like it was damaged cold, before the explosion; that should be their trace.

Re: Guidelines - credit to SpaceX...

Credit where credit is due, but that's to all.

Not sure what you've "seen" from NASA and ESA, but all modern launch vehicles separate the payload fairings well below reaching orbit. In the case of Ariane 5, it's typically between 110km and 125km, depending on payload - anyway, as soon as the heat flux from atmospheric friction is low enough. No launch provider would carry unneeded panels any longer than necessary; payload mass is much too valuable for that.

Who'd be mad enough to start a 'large-scale fire' in a spaceship?

This is not your granddad's Apollo 1 anymore, hasn't there been a requirement around to use only non-flammable construction materials for, well, almost ever? [scratches head]

I actually tried writing the document using Word for Mac first, with OLE. It was just so much easier to do in MacWrite, no comparison!

It's really a pity, to this day, that Apple (err, Claris) gave up on the application-software race.

Ooh yeah, MacWrite!

One of the nice features about Macwrite was the "publish and subscribe" feature, a bit like hypertext years before html became popular. If you edited your embedded image, the new version automatically appeared in the text document. Of course you had to be careful with frivolous editing...

In one university computer lab I was in, essentially all the study papers got written on the four Macs (can't remember the type but might have been Mac IIci's) and couple of Silicon Graphics heavy irons, while the fifteen or so PCs (grey 80486's) stood idle or were used to play Indiana Jones on. Then again, one certain type of mischief, connected to the availability of online bulletin boards, was centered on the Macs: Certain, er, anatomic representations just looked so much nicer in 65k colors than in 256!

Re: Stupid question...

If it's the Earth-Moon L2 point they mean, no, you can't see it from Earth. Which makes this plan a bit funny, as there are two stable Lagrange points L4 and L5 in the Earth-Moon system, from where you could see a bit less than half of the Moon's backside (think Selene's rear in profile) [edit: though not necessarily the lunar poles at all times].

A satellite in [edit: reasonably high, e.g. GEO] Earth orbit would help, though it would need to follow the Moon with a receiver antenna, so you'd probably need a dedicated satellite.

Re: Pictures of Pluto

Funny though it may seem, the illumination is like an early evening on Earth. The images were taken mostly with 150ms exposure time (some with 100ms); a bit too long for hand-held work with a telelens, but short enough so they could take a large number of pics during the overflight.

Re: Denmark?

Are you really sure about that, Lester? I'm fairly sure the corresponding regulations differ between EU countries (except if your motor reload is considered military hardware, in which case the US of A won't let it out of the country). Maybe check with the other Euro rocketry guys over at www.europerocketry.com; or consider Switzerland: They have an annual high-power amateur rocket event so there must be a possibility there to operate largish amateur rockets.

Re: Can´t you

Incidentally, you could launch from Germany with clearance from the local authorities - in this case the DFS - and after having followed a mandatory three-day (?) explosives-handling course to obtain a license to, you guessed it, handle explosives. But if you'd even consider going to rougher climates than Spain or New Mexico, I'd recommend Denmark or Sweden, where I understand the regulatory situation is much easier.

Airbus to build 900 mini-satellites for OneWeb's orbital internet system

Putting them up there is certainly the big issue -

Although designing and building hundreds of sats on a shoestring budget, but with quite up-to-date capabilities, is no mean feat either. Yet, there's absolutely no reason to be concerned: Richard Branson is on the board of OneWeb and is understood to have a contract in his conveniently-sized pocket for launching the satellites - on a vehicle yet to be revealed to the astonished public. And we all know that Sir Richard has never failed to deliver, don't we? Don't we really?

Config file wipe blunder caused deadly Airbus A400M crash – claim

Re: "trying to fly on one engine would make the aircraft very difficult to control or land safely."

Actually, the bird should have been perfectly controllable with one fully functional engine. In fact they were on their best way to a successful emergency landing in that field, when they hit a powerline pole, apparently damaging a wing and resulting in a crash landing and subsequent fire. Without that impact, the engine failure probably would have resulted in just some red faces.

I think, as a phenomenon, this isn't all that new. In the olde days, when someone bought exactly one bottle of Glengrouse every week at the off-licence in Littleton-behind-the-woods, you could easily figure out from gossip that the buyer would be old Colonel Mumblewick. Now you just collect the same data electronically and profile everyone in Littleton the same way. Scary? Not very. Annoying? Probably a bit, to some. Useful? Dunno, might be at some point.

Humanity can defeat SkyNet with BOOKS, says IT think tank

Re: Reading books - wats dat ?

That point is quite well fictionalized in Dave Eggers' The Circle. And yes, I do think all those people who read "1984" in the '80s were influenced by it, to a degree. Certainly, where I come from, it was considered almost mandatory reading, and was quite often cited in public discussion or in the press. Sadly, that has become less frequent.

Elon Musk snowed under with Googley dollars for Space Internet

Rustident Spaceniak

Re: Sat Comms.

Well, your Telstra sat is a geostationary one that's about 40000km away from you in ME - in very rough numbers. Elon's sats will be in low Earth orbit, about 1200km or so, and probably no more than 4000km from you while you have contact with any individual one - rather less. That allows you to get your ping ten times faster, and to use a much simpler antenna into the bargain.

You gotta give the man credit -

he certainly has a knack for trying out things, and a surprising tendency towards reasonable engineering in his wacky schemes. Obviously there are some issues with the necessary reliability of all the technologies in this thing, but you could imagine way more stupid approaches than getting a hundred volunteers to sort out these issues, and then building a prototype. Who knows, at the end of the day it might actually work.

NASA prods sleeping New Horizons spacecraft: Wakey, wakey, Pluto's calling

Re: Horizon name

Nah, you're not alone. In fact you're right. But it's just a sign of the times (at the day), selling a little deep-space robot as someone who'd explore vast unknown spaces, visit strange new worlds where no-one has been before... oh well.

Nonetheless, it is a fine and interesting mission and the best thing about it is, it won't be over just yet. After Pluto it'll probably continue to yet another dwarf planet even further out, so at least it'll have two horizons to peek at - Pluto's and the one of its to-be-decided-upon next target (dubbed, I think, PT-1), and who knows what else?

Re: I see that ...

Skylon is certainly nowhere in a project with a 2020 first-launch target. It is, however, in ESA's long-term plans and that's already a great success for the British (and a tantalizing prospect for all of us). So, just get your facts straight before you start complaining. Oh well, apparently you're British. Just give it a try, OK?

Rustident Spaceniak
Boffin

It's actually two-and-a-half stages!

Nothing is settled yet, but the latest iteration of Ariane 6 isn't four stages any longer. It's the so-called industrial compromise version that comes in two sizes; each with a liquid first and second stage, plus solid boosters - two for the so-called Ariane 6.2 (or 62), four for A6.4. Apart from that, they're pretty much the same.

This latest iteration (which may still evolve quite a bit) was mentioned by Mr Dordain, ESA secretary-general, as the current baseline, and we may assume (I hope) that he knows what he wants.

Give nerds their own PRIVATE TRAIN CARRIAGES, say boffins

Re: Nerd carriage?

I think the first problem with nerds is, they like getting actual work done on the train, such as writing a quick analysis on a complex problem, or at least setting up a spreadsheet that helps them analyse a simplified version thereof. And those nerds i know hate being interrupted by people talking on the train.

Second problem: in the real world, including (to a degree) the Oxford-London-Cambridge triangle, the density of nerds working in the same field of business is low, even on board trains; there are so many different varieties of nerds that the partial pressure of each is low enough to make direct interaction unlikely.

In fact, the reason that it's usually depicted as an apple tree might have something to do with the Latin word for it - malus means apple, but also bad.

But back to the original topic: It's astonishing when you make a quick google search for historic trees in Britain, how many different and fascinating results you get. Wonder if there's a market there for a book telling the story of the land by its arboreal reference points.

Scientists skeptical of Lockheed Martin's truck-sized fusion reactor breakthrough boast

Rustident Spaceniak

Re: Physics 101

100MW is a lot, but these guys are used to dealing with jet engines, which tend to generate that sort of power. Granted, most of that is produced as kinetic energy, but it does start as heat; so if they can produce the power in the first place, I'm reasonably confident they'll find a way to use it.

Then again, those containment walls are frightfully thick, so to get much power through, they'd probably have to be full of cooling channels. Not sure what that'll do to the design, but I'm fairly confident the Lockheed guys have given it some thought. I've only been thinking about it for as many minutes as they have years, after all.

Re: How is that thing at finding Malaysian airliners?

Quite right. What Cryosat is looking for is more like in the many-million-ton range; and anyway, as a submerged sub has the same density and therefore the same gravity as the surrounding water, it won't lead to a surface-level depression!

If my task was to look for a missing airliner, though, I'd still appreciate a good subsurface map as it would certainly help to interpret what I'd see on my echo sounder. Though I guess I'd end up with a more detailed map from that anyway.

Back to a former topic: A sunken gazillion-ton ancient spaceship, now, that would be something completely different from a sub - that would create a signal.
