Debris is Shuttle's Biggest Threat 229

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."

      How many satellites are destroyed on a daily basis by this debris?

      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.
      • Does it have anything to do with the fact that they're in different orbits? I know most satellites are in a higher orbit than the shuttle is, so maybe they're less debris up there?

        I'm not sure either - that's a good question.
        • Yeah, there's less debris up in geosync orbit.

          The probability of a collision is relatively low, and we have the ability to track the larger pieces of space junk (and I believe the Shuttle DOES frequently move around in orbit to avoid known junk), but if a collision WERE to happen, it would be disastrous.

          We just hope it never does happen...
      • It's not enough to see (yet!), but the Earth has
        rings of space junk now. Popular orbits contribute
        the most junk of course, with plenty from launch
        equipment. Then it gets moved around by various
        effects -- moon, solar and magnetic stuff, etc.
        So there are high-risk and low-risk areas.

        It would be nice to just avoid the high-risk areas,
        but that isn't so easy. Sometimes you have to pass
        through them, especially since fuel is limited.

        As if that wasn't bad enough, there's the South
        Atlantic Anomoly to worry about.

      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.

When you begin to approach the speed of light, hydrogen atoms become cosmic-ray particles, and they will fry the crew. So 60,000 kilometers per second may be the practical speed limit for space travel."

      You did read the tidbit that pointed out it would be cheaper to build a NEW Hubble based on the same plans, upgrade it before launch and launch it, then to do a repair mission to it, all things considered, right? Personally, if they put money into "hubble" it should be Hubble 2, as we could get a LOT more years out of a rebuilt one than with a repaired old one.

      On a side note, I'm not sure why the government doesn't take a "mars rover" approach to more space missions, building and launching more than one of the same craft, and launch them one week apart. This would have saved all the science on the previous (doomed) mars lander, as they would have messed up on the first one, realized their mistake, and landed the second one with adjusted calculations. The incremental cost for a second or third craft will be MUCH lower than the first one, and potentially twice the science can be had from them (think being able to look at two objects instead of one with two hubbles).
      • Exactly.

        As expensive as it is to get mass up into orbit, which would be cheaper:

        Shuttle weighs 4.5 million pounds [howstuffworks.com]
        Hubble telescope weighs 24,500 pounds [about.com]

        Cost per pound to orbit is something like $10k per pound [maglev2000.com], low ball.

        So launch costs for a new hubble would be about $245 million.
        Launch cost for the shuttle seem to run around 1Billion per shot. That leaves 755 million to build a new hubble and apply the refits. The original hubble cost 1.5 Billion at launch, which I presume includes launch costs, devel

Not that I'm saying a shuttle launch is cheap. But your launch cost calculations aren't really worthwhile. You need to look at the cost of a launch for a vehicle capable of lifting the mass of the HST to a 500+ km orbit. It'll most likely still end up being cheaper than the shuttle (although your cost estimate there is a little

Design engineering is expensive, but not the majority of mission cost.

      Luck has little to do with it. Unmanned satellites have the advantage that they can be placed in orbits that are relatively clear of debris. Depending on the mission, I think (and my memory's pretty fuzzy right now) that some satellites have been rad hardened enough to survive in/near the Van Allen belts, an area that is naturally swept of debris.

      Unfortunately, electronics are easier to rad harden than people, so the shuttle must fly in "riskier" orbits from a debris impact point of view. The shuttle is protected in two major ways that I know of: first, a box of space around the orbiter is constantly monitored by NORAD radar. If something enters that box, they assess it's threat to the orbiter and can order course corrections if necessary. This helps dodge a lot of bullets. Second, after the infamous paint fleck that took a chunk out of Challenger's window, flight rules were changed so that the orbiter is oriented with the main engines facing toward the direction of flight at all times. So much better to have a paint fleck put a hole in an ablative nozzle that isn't being used and that will get refitted anyway than have that same fleck cause an explosive decompression.

    Sure, debris in space is hazardous to the shuttle. It's also hazardous to everything else up there, too - including any other manned vehicles we might put up, the ISS, and the entire constellation of satellites in LEO.

    If we're going to stop sending shuttles up, that's not the best reason - the reason to get rid of the shuttles is because they're too expensive, too unreliable, and too inherently flawed for what they can do. Not because they might get punctured by space debris.

    Meanwhile, what we (meaning any terrestrial space agency, not just the US) should be doing is preparing the next suitable for LEO vehicle that can solve most of the shuttle's flaws, and then used unmanned rockets to get cargo into space.

    No, gravity is the shuttle's biggest threat.
  • I thought the biggest threat was incorrect assembly (Columbia), manufacturing defects (Challenger) and parts falling off at launch (Columbia).
  • There is a semi-serious idea that we will eventually launch so much crap up there that we will have to wait for it to fall out of orbit before we can safely launch any new missions...
    • There have been proposals to use small satellites to grab and push objects into a retrograde orbit to burn up in atmosphere. For even smaller things, you could use some kind of mesh or aerogel to catch the objects, then once the sweeper sat has collected enough material, it retros the whole thing.

      Of course, the idea also leads to the idea of having small booster satellites being used to extend the life of satellites whose electronics are still good, but have exhausted their reaction mass.
  • The thing posing the greatest risk are the sorts of things which have already brought two shuttles, or the astronaughts have been quite unnaturally lucky in the many flights.
  • Scrapping the shuttle without any plans for a replacement and no way to pay for it if we did, is just another nail in the coffin of medicrity that the US has laid herself down in. In 3 years we will see plans annouced to outsource manned space missions to China and India. It will be sold as a cost savings but what it really will be is an acknowledgment that the US is no longer capable of producting anything but an entire country of middle managers, ad execs and wal-mart clerks.

    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.

    I'd wager that the biggest threat to Shuttle is hanging the payload off the SIDE of the rocket. That has doomed 2 Shuttles already, while orbital debris has only caused minor damage. No "but, this COULD be a bigger threat", either - the major danger to Shuttle and crew is one of the vehicle's "features". Rockets with payload and launch-escape system on top of the contained explosion are inherently safer than mounting the valuables next to the explosives.

'We' in this context is the US and the open passenger market mostly. If tickets were available right now, I wouldn't even consider flying on Shuttle, whereas Soyuz, SS1 or any of the historical capsules are all safe enough. Compare the evidence of Soyuz, Apollo or X-15 to Shuttle for safe ops vs. a dangerous design.

    I'm going to be real cynical for a moment: Not A Space Agency shouldn't be allowed to say Not Another Shuttle Accident ever again! Never A Straight Answer from them...

    The fleet should be grounded and put in a museum and that money rolled into a crash capsule fly-off prize (1 year unmanned, 3 years first manned) and after that paying for tickets instead of operations and hardware.

  • I could have swarned that NASA had a project to collect or at least slow down some of these objects in orbit. It was supposed to be a huge sponge or something. Anyway,about a year ago or so, the project go cancelled for no reason.

    Space junk has been a fact of life in low earth orbit for decades. There is everything up there from gloves to nuts and bolts, all merrily circling the earth. Then we go and send our highly-trained citizens up there who are totally unprepared for any eventuality that they might get so much as a sprained elbow. NOT!

    NASA astronauts have been prepared to die for space exploration ever since NACA was reformed into NASA. It's a complete bunch of nonesense to suggest that missions to outer space in

  • This announcement comes as NASA is considering abandoning yet another multi billion dollar satilite to become space junk, then complaining about it.

    This has been a problem for the last 40 years and, as far as I know, hasn't suddenly become any worse.

    Anyway all objects > 10cm are currently being tracked and catalogued by USSPACECOM radar. I guess eventually we'll reach a point where blasting these debris out of orbit with an Earth or space based laser will become a necessity.

    I have in fact been in simulator training for just this job for the last 10 years, and as an added bonus I am also able to accurately hit those bloody annoying UFOS that mak
  • Get some nukes up there to squeegee the most common orbit paths clean of all the crap up there, including frozen Soviet satellite fuel globs which are untrackable by radar.

    Its been said before and I will say it again here.
    The shuttle has to go.
    It should have been replaced years ago with not one but two new spacecraft.
    One would be a heavy lift launcher capable of launching things like parts for the international space station etc. The ideal solution here is just a big rocket engine (or engines) designed to be as cheap as possible to make and launch without the need for fancy systems.

    Should have a low turn-around time so that once one is launched the time it takes to get ready for another launch is low.

    The second vehicle would be designed to carry crew, tools, equipment, instruments, docking modules (so it can link with space stations like the ISS) and so on. It would be reusable (with as few components needing replacement after each use as possible). Such a vehicle would not need the design compromises that make the space shuttle the way it is.
