Debris is Shuttle's Biggest Threat

Masq666 writes "Tiny rocks, paint flecks and other fragments of junk whizzing around the Earth pose the greatest threat to the shuttles and the astronauts on board, according to the preliminary results of a new NASA risk study. Even coin sized fragments can cause great damage to a shuttle, and the damage can be lethal, if it hits the windows or the heat shield."

      That debris layer is our ablative "alien shield" defense system. Bring 'em on!

      Several years ago I partook in an online discussion regarding the future of space flight, hosted by Jerry Pournelle (sci-fi writer and hobnobber with NASA people.) Prior to my question being posed, a female assistant asked me what my question was, and I voiced something along the lines of 'doesn't all the debris accumulating in orbit amount to a danger' then I posed to question to Jerry and he poo-poo'd my worries with some analogy of a coconut in the pacific ocean. (He did seem to overlook the idea that the analogous coconut would be moving at a few miles per second and could really ding a ship with such some force) .

      Afterwards I told the female assistant I thought he was a daft bugger. She told me he was smarter than I thought and she was his wife.

      A few months later the infamous paint-chip nearly punctured a shuttle window.

      I don't think Jerry was the only one who didn't get it, I've felt there was a valid concern about doing our utmost to limit orbital debris. At the time there was alleged to be a catalog of 8,000+ known objects in orbit, including a power screwdriver. That last item could easily doom a shuttle.

    Why don't they just raise the shields?

      No, no, no... shields are a defense mechanism against energy weapons. Space debris is knocked out of the way by the navigational deflector or main deflector dish. Get your fictional technology right!

    I think exploding fuel tanks and foam insulation have done far more damage than any paint flecks. The biggest threat to the shuttle is management overriding safety concerns in favor of keeping schedules or to save money.

      And that, my friend, is the problem. In todays culture, something actually has to HAPPEN and happen publically before the general populace would take it seriously. How many people thought the danger of a booster rocket leaking was greater than financial concerns before Challenger? How many people were worried about the foam covered fuel tanks before Columbia?

  5. A new NASA "risk study", eh? by Noose+For+A+Neck · · Score: 5, Insightful
    Is this the same "risk study" that they failed to do when they arbitrarily decided to destroy the Hubble telescope rather than repair their most successful scientific mission to date?

    Just wondering, because I read that since Congress actually called them out on it, they're trying to retroactively produce their risk analysis to justify the decision, and this is the kind of bullshit that sounds an awful lot like their same old "we're too scared to do anything anymore" attitude.

    Didn't you ever see Apollo 13? Haise pees into a relief tube in one scene and then activates the urine dump, looks out the window and says "The constellation Urion..."

    Later in the movie they said that they couldn't make any more waste dumps because even that small vector would serve to push them off course.

    Of course, it's a movie... ... but NASA transcripts sort of bear that out as well.

    If something is up there 24/7 and doesn't have the problem, then I'd say the risk is currently small enough for the shuttle.

    The further-out geostatonary belt is called crowded, but only by people who have to point antennas. It is less cluttered with junk and the near-zero relative speeds of everything in it makes what little there is fairly safe.

    The closer you get to the planet, the more crap there is. Some of it is really interesting crap, but it's still deadly crap.

  12. Spaceflight is dangerous by Pedrito · · Score: 5, Interesting

    We're still in the very early stages of spaceflight. It's still dangerous, and it will continue to be dangerous for decades to come. And debris in orbit is only a small factor. The Challenger wasn't hit by debris in space. Neither was Columbia for that matter. Should we stop going into space because of some debris? No. Should we stop going because of the other dangers? I'll tell you what, if we come to a point where the astronauts who are risking their lives, decide it's too dangerous, then I'll start to listen. After all, they're more acquainted with the exact nature of the dangers they face than any civilian or politician (John Glenn excepted).

    You want to talk dangerous, go be a soldier in Iraq. That's dangerous. Why don't we outlaw wars, particularly unjustified, needless ones.

    And while we're on the topic of dangerous, let's talk about automobiles? They're not a great deal safer than the space shuttle.. Why don't we actually make driving tests difficult in the U.S. and outlaw people who can't drive? That will really save lives.

    Space flight is certainly not going to get safer if we stop doing it. The only way to improve is to just continue doing it and making improvements as we learn. Will some astronauts die? Of course. And they know that. It's the risk they signed up for. Why not let them be the ones to decide whether or not it's worth it.
