A Bipartisan Group of Senators Wants To Extend the Space Station To 2030 (arstechnica.com) 56

A bipartisan group of senators has filed a new bill that sets out space policy for NASA over the coming decade. "The new authorizing legislation is largely consistent with much of NASA's present activities, but it differs from White House policy in some key respects," reports Ars Technica. "Most notably, the legislation calls for NASA to support the International Space Station through 2030." From the report: The Trump administration has sought to commercialize space stations in low Earth orbit by 2025, perhaps by becoming a customer on a privately operated International Space Station or by supporting the development of smaller, private labs. "By extending the ISS through 2030, this legislation will help grow our already burgeoning space economy, fortifying the United States' leadership in space, increasing American competitiveness around the world, and creating more jobs and opportunity here at home," said Sen. Ted Cruz, a Texas Republican who chairs a subcommittee on space and aviation, in a news release.

Cruz was joined by three other senators in introducing the NASA Authorization Act of 2019: the subcommittee's ranking member, Kyrsten Sinema (D-Ariz.), as well as Sens. Roger Wicker (R-Miss.) and Maria Cantwell (D-Wash.), who are chairman and ranking member of the Senate Committee on Commerce, Science, and Transportation, respectively. The new legislation follows the NASA Transition Authorization Act of 2017, which Cruz also led and which President Trump signed into law in March 2017. However, almost immediately after that bill became a law, Cruz characterized it as an interim measure to steady NASA through the presidential transition. The new bill is intended as a more expansive view of space policy, and it encompasses the Trump administration's Artemis Program to land humans on the Moon.

    I don't want to generate wealth for a fatcat. I want fatcats to not steal our already generated wealth anymore!

    So we can focus on actually doing and making great things, instead of jobs that a robots can do.

    The ISS is set to be retired because its parts were only certified for 20-25 years when they were manufactured. That is, the engineers designing the parts were told to make sure they would last 20-25 years, and that's what they did. They thought of all the launch stresses, temperature swings from night to day, pressurization, radiation, etc. that the parts would encounter, and designed them to last at least 20-25 years.

    Extending its service life to 30 years isn't just a matter of signing some forms to keep the people paid and the lights on for 10 more years. Every part with a designed service life of 20-25 years needs to be re-examined by engineers, and in some cases tested, to make sure it'll last the extra 5-10 years. And if a part might not last, some sort of patch or replacement needs to be designed, manufactured, sent up, and installed. This is very expensive; possibly more expensive than simply designing a new space station to replace the ISS.

    The modular nature of the ISS does present another possible solution. Design and launch new modules to replace older ones, and simply jettison old modules which have reached the end of their service life. This is somewhat complicated due to the largest modules having been carried up by the Space Shuttle, which isn't in service any longer. So larger modules might need to be replaced by multiple smaller modules (they're playing around with a design for an expanding module, which stores compactly for launch, but expands to a larger volume once in orbit). But it is one way around the problem.

    The Space Shuttle went through the same thing. It was originally only certified for 25 years. Keeping it in service for 30 years required a whole lot of money spent re-examining designs and re-testing parts to recertify them for 30 years. After which the unknowns just became too big, and it was forcibly retired rather than risk an unexpected parts failure, even though its replacement was badly behind schedule and wasn't ready yet.

      The ISS getting old and past it's design life is actually a great reason to extend the life. Think about it. Nothing stays young and new for ever. As the space age moves forward we will have to develop new equipment and procedures to make age related repairs on literally everything. We can't just keep thinking of our space equipment as disposable, some things are going to have to last a few generations.

      • Or we can realize that it's been a very poor investment over the years, and that we should allocate the budget to more exciting and cheaper missions.

            • Repairing Hubble may have been worth it as an exercise. It also didn't prevent the development of a more powerful telescope. We could keep a small part of the ISS going and ditch the rest and still learn all we're going to learn about aging space stations, although arguably we learned enough from Mir to know it is a bad idea.

            Studying how a orbiting structure ages, the type of failures that will occur and the early warning signs of those failures, is the exact opposite of "not producing useful science." Every single person aboard every single craft needs to depend on the reliability of the craft. We know a lot about metallic failure modes. We even know a lot about metallic failure modes in space. However, I would put forth that we don't have a lot of validation of what we know about >20yr/old metallic failures of orbiting

              I would put forth that this knowledge is not worth $100 billion. Instead, just launch an improved version of the original science mission after 10 years or so. Not only do you get nice new metal structures, you also get better instruments and fresh fuel, plus the extra insights from 10 years of experience with the old instruments.

              Also, focus should be on lower launch cost and cheaper missions. It's a shame that we're still working with that old Hubble, instead of flying up an improvement. The problem is t

Things kept moving forward and kept getting safer.

    Entropy is a thing that is real. Even the writer of Ecclesiastes in the Bible wrote about his frustration in seeing his new and beautiful city age and decline over his life. The one thing I can absolutely guarantee you is that everything in this world will age.

    That's the best reason I can think of for extending the ISS. The ISS is aging, and it would be tempting to just call it "Mission Accomplished" and let it burn up in the atmosphere. But it's new science and engineering value now is that it is old. As we move forward in the space age thing will get old with time. Things will break and need to be replaced. Nothing will stay new. The ISS serves as a great opportunity for a test bed of new equipment and procedures for old things in space.

    This is definitely a good idea to continue funding the mission indefinitely.

      This is a very good point and one I have not considered, and its amazing fewer people talk about this.

      I mean, look at the show The Expanse - this is what a realistic future in space looks like, with old, outdated equipment the normal. We can't just be assuming everything will be brand new every 10 years in space. It's not sustainable. We have to figure out how to maintain aging equipment just as we do here on earth.

      • We can't just be assuming everything will be brand new every 10 years in space. It's not sustainable.

        It is if we develop industry in space, with asteroid mining and so on. But if we do that, we can also just build things to last, by using a lot more mass. So it's a waste of time to try to figure out how to maintain these tin cans, instead of figuring how how to build better ones without having to launch the mass to orbit.

      You can replace the serpentine belt in a car in a few minutes, because the engineers one it would wear out and the designed it to be replaced easily enough. There are handy holes going as deep into the engine as necessary to reach the spark plugs because spark plugs wear out and need to be replaced. If an engine was designed without those holes, so you had to disassemble the entire engine to reach the plugs it would be a very different situation. Some equipment has O-rings which you can slip off and slip on new ones. Other, disposable items instead have rubber seals molded in, so they can't be replaced.

      We may be getting to the point where it makes sense to design the next station with serviceable parts. My understanding is that ISS isn't designed that way.
