    EXCLUSIVE: Cause of X-43A Hyper-X Crash Identified
    By Leonard David
    Senior Space Writer
    posted: 12:45 pm ET
    18 July 2003

    SPACE.com has learned that the failure of the NASA X-43A hypersonic aircraft in June 2001 was the result of inaccuracies in computer and wind-tunnel tests that were based on insufficient design information about the vehicle itself.

    On June 2, 2001, the X-43A "stack" -- a modified Orbital Sciences Corporation's Pegasus XL booster topped with the Hyper-X research vehicle -- was released from a B-52 carrier aircraft. Booster ignition went as planned, with the aircraft accelerating on its predetermined high-altitude ascent. Seconds later, however, booster fins broke off and the aircraft spun out of control. The vehicle was then destroyed by range control.

    NASA convened the X-43A Mishap Investigation Board (MIB) to look into the failure on June 5, 2001 at NASA's Dryden Flight Research Center at Edwards, CA.

    The report has yet to be officially released by NASA, but SPACE.com obtained details of the mishap board's findings that were approved in May 2003. Though the report clears the way for the return-to-flight of the X-43A later this year, no one contributing factor is singled out as being the prime cause of the vehicle's failure.

    High-altitude ascent

    NASA initiated the Hyper-X Program in 1996 to advance hypersonic air-breathing propulsion and related technologies from laboratory experiments to the flight environment.

    This program was designed to be a high-risk, high-payoff program, drawing upon the cheaper, better, faster philosophy tightly embraced by NASA during the tenure of space agency chief, Daniel Goldin.

    The X-43A was to be the first flight vehicle in the flight series, built to obtain scramjet technology data. The Hyper-X Phase 1 is a NASA Aeronautics and Space Technology Enterprise program being conducted jointly by the space agency's Langley Research Center in Hampton, Virginia and the Dryden Flight Research Center at Edwards, California.

    Root cause

    According to the MIB documents, the X-43A Hyper X launch vehicle "failed because the vehicle control system design was deficient for the trajectory flown due to inaccurate analytical models (Pegasus heritage and Hyper X launch vehicle specific), which overestimated the system margins."

    The investigative group reports that "during the pitch-up maneuver the X-43A stack began to experience a control anomaly" which led to rudder control failure. Shortly after the rudder stalled, the starboard fin was torn from the vehicle, quickly followed by the port fin, then the rudder and wing.

    The X-43A fell into Pacific Ocean waters within a test zone off Point Mugu, California. No attempts were made to recover physical evidence from the X-43A. It now rests some 1,200 feet below the surface.

  17. Meta-mod == gift to trolls on Survey of Linux-Based Gadgets & Devices · · Score: -1, Troll

    I've seen several posts recently where people complain about having "infinite" Meta-Mod points. Almost like it's a burden.

    It most certainly is not. It is a gift to patient, karma-whoring trolls. Read the Meta-Mod FAQ.

    Say you encounter a typical "OMG BILL GATES IS TEH SATAN!" post by, say, circletimessquare. It's been duly modded up as "Insightful" by some unknown editor or slashbot. Why not Meta-Mod that as "unfair"? Sure, you won't have any significant effect on either the poster's karma or the person who modded them up, but you will "help ... remove bad moderators from the M1 eligibility pool."

    Similarly, suppose you encounter a post by a troll seething with racism and hatred. It's been duly modded down as "Troll" or "Flamebait". This too is "unfair"! That post increased the noise, and as such was very valuable. It belongs in +2 territory with something by Perens, surely! Whoever modded that down should be removed from the moderation eligibility pool, post haste!

    (Note that you don't have to support the racist shite in the post. The poster probably doesn't either; he's just doing it for the reaction.)

    This is the same thing that happens to positive-karma troll accounts when they upmod a troll. They're found out in Meta-Mod, and lose their ability to moderate.

    It's time the trolls use the same weapons as the slashbots! If you moderate, use "-1 Overrated" since those don't get Meta-Modded. And Meta-Mod whenever you get the chance! I mark almost everything as "unfair", though I occasionally see a very obvious troll being upmodded, which I mark as "fair" or leave alone.

    Either that, or just have fun. Whichever.

    Take a look at the Fyodor Interview. Scroll down to this comment which asks, in a polite fashion, whether Fyodor has ever chosen to use his hacking skills to break the law, and cites the Slashdot troll hacking incident detailed earlier in my journal. This question received a score of 5 from the users of Slashdot, and was therefore eligible to be part of Fyodor's interview.

    Today, alert reader Gendou pointed out that four days after the story posted, a flurry of moderation activity had occurred in this posts's thread. The post was moderated down as a "Troll", heavily, till it reached threshold 3, and every comment in the thread which mentioned Fyodor's hacking incident also received large quantities of "Troll" moderation.

    Now, who gets moderator points, opens up a four day old story, and starts using moderation to push an agenda? More than 5 points were used in the attack, which means that either a large group of users acting in concert attacked the thread, or a user who is gaming Slashdot's system attacked the thread, or an editor did it. Who was bent on removing any shred of legitimacy from complaints that this question was not forwarded to Fyodor?

    The users of Slashdot gave this comment a score of 5.

    Slashdot Moderation is unaccountable, and I don't know who did this. For now, I'd like anyone who saw that the users of Slashdot moderate this question to 5 to vouch for that fact in the comments, as I am vouching here. We may never find out who manipulated the comment scores, but we can set the record straight.

    I know I've been making a lot of noise about how meta-mod can be used as a tool to increase the noise.

    Here's a real-world example. This post came to me for meta-modding. The moderation I was assigned to meta-mod was the one UP-MODDING the post to "Interesting". Of course I marked it "fair", because whatever moderator sacrificed a mod point for that post deserves to be rewarded.

    By meta-modding that moderation as "fair", I'm helping ensure that moderator gets mod points again.

    Conversely (inversely? I can never remember), there was this post. My job was to meta-moderate one of the upmods given to it ("+1 Interesting"). *YAWN* That's surely not noise. Whatever moderator used a point to mod that up surely doesn't deserve to keep his moderation ability, so I mark it "UNFAIR".

    I wish I had a better example of an "UNFAIR" moderation, but you can imagine a slashbot spouting some tired anti-Microsoft FUD. When these are modded up, I mark those moderations "UNFAIR" with extreme prejudice.

    In this way I'm using Slashdot's own moderation system to reward trolls and punish... well... anyone who isn't a troll.

    If more trolls were to (ab)use the meta-mod system, it'd be safer for them to abuse the MOD system, and hasten the inevitable Slashdot implosion. I get the opportunity to meta-mod twice a day. It takes a couple of minutes, and I get to do my part.
