    Here's why people apply and who applies: Some do it for the 15 minutes of fame, surely, but many others are serious about it. They know the risk, they know it's a one-way ticket, but their lives are going nowhere on this planet, they've got nothing to lose and this may be just the ticket for them to do something useful for humanity.

    That has to be the funniest thing I've read all day.

    Airships can no-doubt fundamentally change the arithmetic of delivering supplies to these hazardous and remote locations. If these airships prove to be reliable heavy-lifters

    The problem, well known historically but seemingly needing to be rediscovered every twenty years or so, is that airships aren't reliable heavy lifters. They're extraordinarily sensitive to the weather - much more so than any means of transport they replace. Absent heavy and complex propulsion systems (above and beyond that what's needed to travel from point A to point B) or significant ground infrastructure, they can't reliably deliver their cargo to a precise given point. etc... etc... (Worse yet, both of these fundamental problems get worse as the size of the airship approaches any useful cargo capacity.) This scheme doesn't solve the first problem, and probably won't solve the second.

    Here in the real world - that option is rarely if ever available. We have to make do with the situation that faces us. We have to make trade-offs between building infrastructure where it's at some degree of risk, or not building it at all.

  20. Re:This shouldn't be news on Court Orders Retrial In Google Maps-Related Murder Case · · Score: 2

    I think it IS newsworthy for two reasons : first, it shows yet another example of how utterly fucked the adversarial legal system in the US really is. The goal of this fucked up legal system is to "win", not to find the truth, and the assholes who prosecuted this case ought to be disbarred for their enthusiasm toward suppressing crucial evidence.

    What's fucked up is that you can be so clearly and utterly clueless - yet still get modded insightful. The prosecutors didn't suppress evidence - the judge ruled that experts couldn't testify. And that's his bloody job. And reading TFA, I can't say that I think he's entirely in the wrong - because the defense screwed the pooch in the first place. (By not getting a properly qualified expert in the first place, and then by potentially violating the rules of evidence.) Pointing out where the defense screwed up is the prosecutors job, and vice versa.
     

    Second, the news has a technical aspect because the "evidence" of the Google Maps search may have been planted on the machine Cooper supposedly used. If such details as info stored in a browser cache can be the point on which a man's freedom hinges, this is technical news of importance.

    Hardly. This isn't the first such case, nor a particularly notable one. "It happened on a computer" isn't enough to make it newsworthy anymore, that ship sailed decades ago.

    It's in the textbooks.

    That doesn't make it true. The design choices and the steps along the way that lead to the Shuttle's final configuration are well documented.
     

    . A join that would not have been there before a design change that allowed different parts to be built in different states had a seal that fell below the glass transition temperature of the polymer in the seal and it fractured. If the join was not there the seal would not have been there.

    Those of us who have actually studied the space program know that the reason the joint is there is because the segmented solids were chosen over monolithic solids. Even if monolithics had been chosen, the parts would have been built in different states. Hell, even if monolithics had been chosen, there's a good chance there would *still* be joints in the case in order to avoid handling one whole. So, yeah, you haven't a clue what you're talking about.

  24. Re:Doesn't surprise me at all on Chris Kraft Talks About The Decline of NASA · · Score: 1

    The dual-use thing came only because the plans were for more Shuttle than NASA could afford by itself. If they had started with a smaller, less ambitious, and of course, less costly Space Shuttle, then they wouldn't have needed DoD money or gotten those DoD strings attached.

    *Sigh*. And again, /. demonstrates it's ignorance of the history of the Shuttle program. Seriously, utter and complete cluelessness.
     
    If you actually study the history of the Shuttle program, you'll find that's exactly what they did. The first Shuttles were small vehicles intended to shuttle crew and very light cargo back and forth between Earth and a space station launched by a Saturn V. Then the Saturn V was essentially cancelled when it was defunded in 1967, leaving the Shuttle without a destination or a purpose.... and the Shuttle began to grow in size and complexity to serve as a flying pickup rather than a flying commuter car. (All the DoD really did was finalize the size of the pickup truck.)

    Also the sort of games you describe were the direct cause of the Challenger disaster - a part introduced due to a design change to spread around the pork failed and killed seven.

    *Sigh* Seriously, this bit of urban legend bullshit either needs to die in a fire, or people who believe it need to have "too stupid to live" tatooed on their forehead.
     
    Boosters (and drop tanks) were added to save money, correct performance shortfalls, and simplify the design. Solid boosters were chosen over liquid because they were cheaper, simpler, and easier to design and validate. Segmented solids were chosen over monolithic solids for a whole laundry list of technical reasons. It's really as simple as that. Yes, a powerful senator happened to come from that state, but correlation isn't causation. Equally, the company that got the contracts for the solids was a strong contender regardless of the type of solids chosen - no tinfoil required.
     
    The thing that *actually* lead directly to the Challenger disaster (poorly designed joint seals)*... nobody seems to know how those were chosen. In the blizzard of paper that went back and forth between Morton-Thiokol and NASA, the joint design seems to have 'just appeared' and nobody questioned it. When the same failure that destroyed Challenger (joint rotation** leading to blow-by) appeared in testing, the 'back-up' o-ring was added as a quick, cheap, fix rather than questioning the design. Fixing it right could have been expensive and potentially time consuming - and NASA had neither budget nor time.
     
    During development, everyone assumed the backup would never fail - yet it almost failed on the first flight. It continued to fail to some degree regularly thereafter. These failures were so common and raising such a level of concern that a new joint design was created that addressed the root cause... (This is why NASA had a fix proposed so soon after the accident - it was already in the pipeline.) But they continued to fly anyhow, until the joint failed entirely.

    * Yes, I know the soundbite version is "they got too cold". Like all soundbites it contains an element of truth, but there's a whole hell of a lot more to the story.

    ** And if you look at the fix - it contains not only heaters to protect against the cold, but additional pins to hold the joint from rotating and opening up and additional o-rings in vulnerable positions. There's a reason for that.
