A Look At Orion's Launch Abort System 37

Posted by Soulskill

An anonymous reader writes: With the construction of Orion, NASA's new manned spacecraft, comes the creation of a new Launch Abort System — the part of the vehicle that will get future astronauts back to Earth safely if there's a problem at launch. The Planetary Society's Jason Davis describes it: "When Orion reaches the apex of its abort flight, it is allowed to make its 180-degree flip. The capsule of astronauts, who have already realized they will not go to space today, experience a brief moment of weightlessness before the capsule starts falling back to Earth, heat shield down. The jettison motor fires, pulling the LAS away from Orion. ... Orion, meanwhile, sheds its Forward Bay Cover, a ring at the top of the capsule protecting the parachutes. Two drogue chutes deploy, stabilizing the wobbling capsule. The drogues pull out Orion's three main chutes, no doubt eliciting a sigh of relief from the spacecraft's occupants."

I believe what you're calling "politics" is something more fundamentally important. In the '60's everyone just knew what it was silly to suggest that anyone without a penis could be an astronaut. That notion is stupid of course, but there are still a lot of us who don't fully get that; even today, in 2014.
BTW, thanks to OP for sharing this. I don't think I'd ever heard of Jerrie Cobb before today. I did, however, immediately reflect on one of her peers, Pancho Barnes, who probably taught several hundred pilots of the Mercury 7 generation to fly.

It's part of a paid smear campaign, intended to establish a belief that Linux is difficult and unreliable. Have you noticed how every discussion about Linux/Foss on Slashdot is centered on these weird corner-cases that almost nobody in the real world ever sees?

Well... in this case, not so much. When it comes to audio support the linux landscape is a minefield of poorly documented, often unstable crap with poor interoperability. In other words, most of it is shit. None of it works well without considerable tweaking, after spending far to much time and effort running down solutions in those support forums. Don't get me wrong. I make my living running linux boxen. I am also a semi-serious audiophile and would love to use linux in that pursuit as well. Can't do it.

This kind of thing is inexcusable. It is clearly unethical and it should be illegal. Think we'll get a law like that passed? No, I mean one that doesn't tie the hands of our friend, the government, whom we must entrust with secret powers to keep us safe. I just mean shady operators like Whisper..., and Google.

Bullshit. A natural monopoly exists WRT the distribution media. It is not in any way reasonable to expect a free and open market when all comers are allowed to string their own copper or fiber. We can argue about who gets to own the infrastructure, but until real competition is enabled, we will always have the abuses typified by the current crop of monopoly holders.

I have a perfect, 100% effective solution to this problem: I don't, and never have used 'The Cloud' in the first place. It's a stupid concept, it's poor data security, it's a waste of money, and you're asking for trouble if you use it. Store your data some other way that you have 100% control over, don't let complete strangers do it for you.

I beg to differ. We use cloud storage to keep copies of some very important documents (compliance requirements) that are central to several business processes. One copy we store locally, and the other we store in the cloud. Both are encrypted before storage so the security question is meaningless. You could lift all those files, from either location, and have nothing without the key. What's not meaningless is the savings we gain by using the cloud for that backup copy. Duplicating that store, including the geography, using hardware we own is certainly possible, but nowhere near as cost effective.

I find that local backups are better than cloud backups. I have a 1TB external hard drive that's nearly filled up.

What you have described is not a backup. It's a copy, a copy which is sitting right next to your original; subject to most of the same threats as the original. I wish you luck.

I hate hardware and for all intents and purposes it can go shove itself up its own ass. As a result I very much love the cloud, no matter how much of a buzzword it is. Let someone else worry about the tedious busywork it is to get one piece of hardware to talk to another. Oh what's that? A disk died? I don't give a damn because I don't have to drive 30 minutes each direction just to change it. Ha!

You aren't encumbered by any compliance regulations, are you. Just sayin'...

HOLY MACRO!
