      Except when the shuttle is tumbling all over the place and the antenna is not pointing anywhere near one of the receiving stations... The recorder could contain some information that it gathered while the shuttle was out of control. A large chunk of the "last 32 seconds" of data transmitted by the shuttle is missing and/or unusable. The recorder will hopefully be able to fill in the gaps there and maybe give some clues to what happened even later in the process.

      Also, there is a very long period (about 16 minutes) during re-entry when radio communitation between the suttle and ground is impossible due to the ionization of the air around the shuttle at high speeds. Columbia broke up during the radio silence, so whatever information ground telemetry recieved wouldn't have been too useful.

      What is most remarkable is that the medium is TAPE. With all the improvements in storage technology, it's amazing that tape is still (apparently) the most effective means of reliably storing and recovering data in catastrophic situations. Of course, Galileo's tape system survived numerous passes through radiation fields that would have fried many systems, so I guess we shouldn't be surprised.

      If you're backing up serious data, tape is the only viable solution.

      The technology is old. Or rather, mature. Most, if not all of the bugs have been worked out years ago. At work we have some LTO drives. IIRC, they can be written to at 20 mbytes/second, and they hold 60 gbytes uncompressed (and 120 using the hardware compression. Granted, this assumes the data isn't compressed already. Realisticly, you can only get about 80-90 GB per tape.). You can engineer tapes to be increadibly resiliant to almost anything. The only moving part in DLT or LTO tapes is a spindle that can be turned by the drive. The spool is unwound into the drive itself, and rewound back into the tape cartridge. There are also 2 spool designs with the 'read area' in the middle like cassette tapes. There are also tapes in the 100/200gb range, and the speed and size keeps increasing linearly.

      What other medium's are out there?

      1) CDROM/DVDROM Slow to write, and not much data. Good shelf life (20-30 years) though. Usually CD's are used for 'archival' purposes. AKA "The IRS decrees that this data must be kept for the next 15 years."

      2) Flash? it's solid state, and no moving parts, but the write speed SUCKS for real data sizes. Also, the density just isn't there. IIRC flash cards top out at 512 mb now.

      3) Hard disk? WAY to fragile. We moved a batch of 20 or so servers with about 2 TB of disk this weekend. We lost 7 disks (of around 150).

      At this point, untill someone comes up with a remarkably new idea, tape will be the king of long term, high density data storage for the forseable future.

      While I won't argue about write speed, Flash in cf format is becoming available in capacities of 4 Gig, see story at C|Net. Doing ide raid with this would cover much of the speed barrier by distributing writes across many cards. It would also increase capacity.

      How much data is going to be captured anyway. If it is a stream of values for several sensors sampled at 8khz, is doubtful to exceed the write speed of the current types of flash.

    I fail to see why this was moderated troll.

    Who was I supposed to be trolling? Are you saying that there are a large number of people reading /. that 1) are involved in the design of the space shuttle and 2) want to keep the system the way it is, so that more people will die, and that I'm therefore trolling them?

    And can you give me an example of the "predictable responses" this is supposed to illicit?

    Even if you meant it in the less common sense ("a troll is categorized by containing some assertion that is wrong but not overtly controversial") can you explain what is wrong with the idea of opening up the shuttle design process? If an institution is failing to do its job and people are dying as a consequence, one of the best ways to fix the problem is to enable a large number of people to see (in detail) what is going on, motivate them to care, and motivate the system to listen. Bridge design (to name just one example) improved dramatically when these three conditions were met (large number of people study the designs, they care because they and people they care about use the bridges, and companies that build bad bridges don't prosper). You may disagree but that doesn't mean I'm a troll!

    I suppose getting moderated "troll" for suggesting a way to fix problems before someone dies (instead of forming a commitee to investigate each tragedy as it happens) is better than getting moderated "offtopic" for responding to the article instead of to the blather of all the people who didn't read it, but it's just as anoying.

      I didn't say that the engineers don't care; far from it, the ones I've worked with and the greater number that I've known personally all care a great deal. But the system in which they are forced to work is so bogged down in blockheaded management systems that it doen't matter if they care or not. And I'm also not saying that the managers don't care; the managers are stuck in the same disfunctional system and many of them are even more frustrated.

      The big problem is that nobody knows what's going on in any effective sense. The ones that have access to the big picture are insulated from the details, and the ones that understand the details of part 163-A(7) don't have access to the people who know subsection R-395.b like the bottom of their coffee cup. I am not saying that they don't care, I'm saying that it doesn't matter if they care or not, because they are hog-tied in red tape and arc welded to a juggernaught.

  12. OXE recorder by dpilot · · Score: 1

    I was skimming sci.space.shuttle last night. There had been a general "no flight recorders" statement about the shuttle by the more authoritative contributors to the group ever since this discussion on the launch began. Then this news came up.

    It turns out that these flight recorders were done for Columbia and Challenger, and dropped from subsequent shuttles, since telemetry was deemed sufficiently reliable. Then everyone forgot about these OXE recorders, until one was found.

    There was some mention about some other recorders that could yield useful information, but how that fits into the "no flight recorders" statement, I don't understand. I can see the point on the OXE recorder. There was some discussion that a data vs bandwidth choice has to be made on telemetry, and that more complete data can be found on recorders. I'd think there'd be a similar data vs tape space decision on a recorder, too.

    America used to have a conscription program, where young adult males were forced to serve in the Armed Forces. It wasn't very popular.

    Babies and 103 year old grannies take medicines. Would you advocate drafting random people, including babies and 103 year old grannies in to drug trials.

    Leo Szilard , Atomic pioneer, gave up Physics after participating in the development of the Atomic Bomb in World War 2, He had a suggestion for how to react to the preseence of Nuclear weapons.

    His suggestion was an alternative to drafting 1 million young men, and wasting a year of productivity, putting them in the Armed Forces, and spending a huge fraction of the Nation's revenue building expensive weapons for them. He was still going to draft them, but rather than wasting their time in the Armed Forces, he suggested the USA and the USSR merely exchange hostages.

    Each country would be responsible for feeding, housing, and putting said hostages to work, within agreed upon limits.

    If one of the countries attacked the other, the attacked country was authorized to kill some of all of their hostages.

    One of the long term advantages of Szilard's plan was, if Soviet hostages were billeted in American homes, and vice versa, hostages returning after their hitch would have a much better understanding of the other Nation's people and culture. They would have friends over there, maybe would have fallen in love. All of which would make it a lot harder to imagine launching a nuclear exchange.

    So how can the idea be improved? Instead of a draft, have a lottery maybe? So you have to pay a buck for a chance to go up? No one goes against their will, but knowing that your friends and family might play would involve even thouse who don't play. That would still create a lot of interested parties, though perhaps biasing the sample towards the more optimistic.

    The recording device can survive concussion and damage at most a few centimetres of tape, what was wound onto the take-up spool will probably be OK.

    The engineering required to remove said tape and play it back on a different set of heads is much less complicated, touchy, and error-prone than that of say, a hard disk.

    Attempts at falsifying / otherwise fudging the data would be more easily apparent, IMHO.

    Because it's linear, concussion might be apparent in the recording, but it won't cause it go completely haywire.

    The tape medium itself is not too rigid, but put inside a toughened metal box (I don't know what they're made of) and you're right, we shouldn't be too surprised so many people still use tape. Even if a small part of it is damaged, it probably won't have destroyed the whole recording, unlike many other all-or-nothing storage media.
