Russia To Save Its ISS Modules

jamax writes "According to the BBC, 'Russia is making plans to detach and fly away its parts of the International Space Station when the time comes to de-orbit the rest of the outpost. ... To facilitate the plan, RKK Energia, the country's main ISS contractor, has already started developing a special node module for the Russian segment, which will double as the cornerstone of the future station. ... Unlike many Nasa and European space officials, Russian engineers are confident that even after two decades in orbit, their modules would be in good enough shape to form the basis of a new space station. "We flew on Mir for 15 years and accumulated colossal experience in extending the service life (of such a vehicle)," said a senior Russian official at RKK Energia...' Is Russia the last country where engineers are not (yet) forced by corporations to intentionally produce designs that fail two days after warranty expires? There used to be a lot of equipment manufactured by various countries (Germany is the first one that comes to mind) that lasted virtually forever — old cars or weapons systems, but one rarely sees anything of the sort these days."

  1. Why burn them up? by KasperMeerts · · Score: 4, Insightful

    Instead of just plunging them in the ocean, wouldn't it be much cooler to put them in an orbit halfway between the Earth and the moon, as a sort of testament for future generations?
    It could be something like the pyramids or the the Eiffel tower or the Chinese wall.

      Yes, it would be cool to have space junk at a Lagrange Point. It'd be even cooler to actually use it rather than leaving it as an hazard. However, I doubt if the station has that much propellant.

      1a. It takes a lot of energy to move something the size of the ISS into an orbit high enough not to fall on our heads in the relatively near future;

      1b. There is no orbit halfway between the earth and the moon. Even if you considered one of the five "stable" Lagrange points, they are not all that stable in the long run, not for unattended, unfueled vehicles anyway;

      2. I think it admirable that the Russians are not merely throwing their stuff away but at least show the willingness to keep it up there and try to reuse it. Even if this fails in the end, they will learn a lot from the attempt. And too many of us are conditioned not to maintain and repair things, but throw them away when they break (or even when they're simply not in style anymore) and buy new.

    Mars rovers? Voyager? NASA seems to be doing okay with that.

    More likely than not, America is going to allow Bigelow to attach a few units on there and they will ultimately replace the cans. They will be cheap and 100% appreciated by the occupants since they are MUCH BIGGER and QUIETER. In fact, if Obama and Bolden (our very likely next NASA head) were smart, they would continue COTS-D AND buy a Sundancer to attach to the ISS. Since NASA will not likely want to trust the Sundancer, it can be used for storage and the door kept closed in normal use. It will cost us 200M (assuming a falcon 9 launcher), which is chump change. By getting Bigelow started, it will lead to cheap new space stations for NASA, private space station, and perhaps military (important in light of China's new announcement of their multiple military). Finally, the Sundancer and the metal noodes can be replaced by BA-330's increasing the size of the ISS appreciably.

    No, but the space industry is one of the few where things are built to last. Portable consumer electronics are among the worst for quality except for a few notable examples like the iPod Mini and the Nokia 6310(i). Soldered-in lithium batteries, surface-mount MLC flash memory and electrolytic capacitors don't last all that long. Satellites are over-engineered, if anything goes wrong with them you can't put it in a cardboard box with styrofoam and send it back to the manufacturer.

    The quality of cars hasn't actually gone down - when The Wall was knocked down lots of old Soviet cars like the 2-stroke Trabant were abandoned for second-hand German cars. Of course manufacturers are filling up modern cars with cheap consumer electronics and cheap Chinese DC motors to move every little thing because apparently buyers are too lazy to use their hands for anything. So while all the in-car entertainment and motorised windows,cup holders, sun roofs and central locks might break the car itself (engine & chassis) will probably be in a better state after 20 years than a '70s car would have been after 20 years since engine technology has improved and the underside of the car is better protected from rust.

  5. Survivorship bias by ex-geek · · Score: 5, Insightful

    It is called survivorship bias. Almost all of the things produced in the past have long since broken down. We only see what stood the test of time and therefore tend to assume that things were built to last back in the day.

    1. Re:Survivorship bias by WindBourne · · Score: 4, Insightful

      While I agree that there is a bias built-in, the simple fact is that things WERE better built 50 years ago. The reason is simple; Steel vs. plastics. Today, the items are likely to be made out of plastics which do not last as long. The reason is costs. The items that survived from long ago WERE EXPENSIVE. But look at today's goods. If you buy something from Target, Walmart, heck even American Furniture, it was likely made in China, was made out of the bare bones minimal wood, screwed together (maybe), and costs a great deal less. OTH, if you buy an ethan-allan piece, it is heavy, much better wood, better construction (rabit groves, etc), glued AND screwed, 10 or more coats of fine laquer, etc, etc, etc. And what does it cost? 10x more. Which is going to last for another century?

      It isn't so much a case of metal vs. plastic as of things being designed with computers and modern materials.

      An engineer working on paper would deliberately over-spec the materials and parts to account for margin of error, but now computers loaded with precise details of each material available can calculate exactly what is required to, e.g. pass a particular safety test or hold a particular load.

      There was a BBC Horizon program which mentioned this back in 1982. Back then it was standard behaviour to over-spec anything safety related (e.g. bridge supports) by a factor of three, a it tended to spill over into non-safety things too. I don't know what they do these days.

  6. Old Stuff by raygundan · · Score: 4, Insightful

    Old stuff seems to last forever because the old stuff we have left is the stuff that survived. It's a self-fulfilling prophecy. There's plenty of old junk-- but that went out with the trash years ago. Every era manufactures a bunch of unreliable crap, too.

    To make matters worse: through sheer chance, some unreliable junk survives for a century now and then, too. While this stuff is all at the statistically unlikely end of the bell curve, and 99.9% of its cohorts have vanished, what remains by dumb luck reinforces the idea that "stuff was made better in the old days."

    Isn't part of the reason we have a space station to learn how to fix stuff when it breaks? How are we ever going to explore space if we have to head back home because the widget broke three months into our trip to mars.
