ISS Will Plummet To a Watery Grave In 2030 (theguardian.com) 87

The International Space Station (ISS) will continue its operations until 2030 before heading for a watery grave at the most remote point in the Pacific, Nasa confirmed in a new transition plan this week. The Guardian reports: More than 30 years after its 1998 launch, the ISS will be "de-orbited" in January 2031, according to the space agency's budget estimates. Once out of orbit the space station will make a dramatic descent before splash landing in Point Nemo, which is about 2,700km from any land and has become known as the space cemetery, a final resting place for decommissioned space stations, old satellites, and other human space debris. Also known as the "Oceanic Pole of Inaccessibility" or the "South Pacific Ocean Uninhabited Area," the region around the space cemetery is known for its utter lack of human activity. It's "pretty much the farthest place from any human civilization you can find," as NASA put it. Nasa said it plans to continue future space research by buying space and time for astronaut scientists on commercial spacecraft.

    The Russians have been talking about re-using their modules for something else. So is the entire thing going to be de-orbited or will parts of it live on?

    Shame they can't preserve it for posterity.

      Really? From what I recall, it's the Russians saying their modules are too old to maintain that is one of the primary factors driving the end of ISS operations.

      "We can't risk the lives [of our cosmonauts]. The situation that today is connected to the structure and the metal getting old, it can lead to irreversible consequences - to catastrophe. We mustn't let that happen," Deputy Prime Minister Yuri Borisov was quoting as telling state TV. source [bbc.co.uk]

      Even the "new" Nauka module is fifteen years old, so by 2030 I suspect it will also be in the "reached the end of their service life" category.

        Better source [phys.org] : In recent years, the Russian segment of the ISS has experienced a string of problems, including air leaks caused by cracks, raising questions about the safety of the rotating crews onboard.

        "Around 80 percent of the inflight systems on Russia's segment have reached the end of their service period," Vladimir Solovyov, chief engineer of the Energia rocket and space corporation, told the RIA Novosti news agency.

          With the Mir, it was either ditch it, or it will ditch itself on it's own.

          Same thing with ISS. It's just too old to fix. 2030 I think is way too optimistic.

        AFAIK (haven't managed a lot of research into this belief) we've deorbited all of the stations we've launched into space before they were no longer human usable. Have we left any modules in space to look into the degradation of the materials and how long it actually takes to no longer be safe for humans to be on board, and what materials or methods can be used in space to extend the life of the materials?

        • No. The ISS is a genuinely large space craft, some 100m in length, therabouts, just letting it break up in space has two effects.

          1) We actually know what happens. We dont NEED to do this, the science is already fairly sound.
          2) And that science includes leaving a ridiculously large amount of debris in orbit posing threats to sattelites etc.

          Theres no good argument for leaving it up there once its past its use-by. Its time to put the old girl to rest.

            True, I was thinking more of a single module station that would likely not breakup but just degrade the atmosphere seals I'd think. Could leave one of those up beyond its human usable life and still be able to deorbit it later. I was asking more if any of this type of experiment has ever been done.

          One of the early experiments on the Shuttle system was the Long Duration Exposure Facility [wikipedia.org] which was intended to answer exactly that sort of question.

      IMHO, it is outstanding that it has lasted so long, going over what it was expected to do in the first place given a defined time span.

      Keep in mind that this a different context that where we live in basically at the surface of the planet.

      There is all kind of data collected along the life of such a station with regards with the actual environment where it does its task and the fact that they could prolong the expected initial life expectancy is interesting.

      My thoughts exactly, should it be kept as a museum piece that our grandchildren could look at and think "how quaint". To ditch it would be a huge loss of heritage. How much fuel would it take to push it up to a parking orbit where it could stay for a long time ?

        Can the International Space Station be moved to a higher orbit, like halfway between the earth and moon? [quora.com]

          Another question is do we really want to do that, even if we could? If we moved it to a parking orbit and basically abandoned it, it will eventually begin to break up. Tidal stresses over the years will play on it. Without active maintenance and fuel for the thrusters so it can dodge orbital debris. Impacts from this debris will cause more debris to break off the space station. Can you imagine the amount of orbital pollution this thing would make as it breaks apart?

          It will be destroyed. The ISS is in a naturally decaying orbit and periodically needs to boost back up - it's altitude actually varies quite a bit. If you abandon it, it will likely de-orbit based on orbit decay within a few years - it's quite close to touching the tendrils of the upper atmosphere. Sometimes the atmosphere expands due to solar winds causing even

          While the individual modules would probably be strong enough to sit under their own weight on the ground, that's a lot more challenging for the (relatively small diameter) connectors between the modules. And as for the radiator panels and solar panels (obviously at right angles to each other) ... the connectors between them and the main body are even skinnier.

      • I think it's safe to say moving ISS up into a parking orbit has been ruled out.

        For museum use, it would be interesting to save some piece of it by bringing it to Earth. The Space Shuttle had the capability to bring payloads back from space, but AFAIK nothing currently exists to do that. Maybe the Starship could if it's operational by then? One good candidate for an item to be saved would be the Cupola - it's a very iconic module, pretty small and in a spot where it maybe could be removed.

    • First of all, Rogozin was very pissed because the Americans did not ask him at all and did not agree the date with other program participants. They decreed 2030 and treated the rest of the world as scum.

      Second, some of their modules will be towed away and used as a station core. That is planned - the new Pirs module is definitely one of those.

      Third, it will happen BEFORE 2030. Their target date was 2027 when they get the nuclear tug in orbit. However, with the current political situation that may happen

    • The thrusters that will be used to de-orbit the station are in the Russian segment.

      The old modules are not really in a great shape, and it would be a huge problem to detach them. Not only are there all kinds of internal and external connections between them, the different modules don't have their own propulsion systems so separating them safely would require some other, as yet nonexistent, spacecraft to act as tugs.

    Want to get away from it all? You can't do better than a point in the Pacific Ocean popularly known as 'Point Nemo,' named after the famous submarine sailor from Jules Verne's Twenty Thousand Leagues Under the Sea.

    so tells us NOAA [noaa.gov].

    How would NASA, or its equivalent, decommission things such as the ISS since there wouldn't be these open areas to drop them into?

        The second issue is what burns up and what doesn't. Some materials will burn away into gases, but some won't. With the ISS you are going to get quite significant chunks of metal reaching the ground.

        In this hypothetical scenario I think the only reasonable option would be to dismantle the ISS and boost individual parts of it into graveyard orbits in a series of missions, and de-orbit stuff that will burn up completely.

        Specialized thrusters that carry lots of oxidizer and use the structure itself as fuel would be ideal. Think of it as the rocket equation in reverse. The more of the structure you convert into fuel the more efficient your thrusters become at moving what is left. Before you know it remaining modules are well on their way onto someone else's solar system. Who knows maybe someday it will become a tourist attraction.

      Some options:

      • Deorbit into other big unpopulated areas (deserts, mountain ranges, etc)
      • Require spacecraft to be designed so precisely-targeted reentry is possible (the ISS is a big weird shape and so there's a lot of uncertainty about where the bits of it will land)

      Probably the best way to do things in your thought experiment is to break the ISS into small sections before deorbiting. Then the small sections would mostly burn up in the atmosphere and what reaches the ground would have minimal effect.

      It would be a shame, and yes, useful parts could be saved that way. While other people have pointed out that the pressurized modules, especially the Russian ones, are starting to leak air and are developing alarming cracks, and even the US modules have ongoing mold and mildew problems, the station has brand new batteries and brand new solar panels, and a great deal of external equipment that still works, like CanadArm2.

Once the commercial operators develop a capability which was formerly only NASA's, it is time for NASA to move on to other things that the commercial folks aren't doing. An analogy I've seen is that when NASA needs someone to go across the country, they don't (usually) send them on a NASA owned airplane, they buy a ticket on a commercial airliner.
