      @@anasqai Dry ice? Oh I see, nitrogen. No, there is no cooling with 'liquid' nitrogen needed here. They do use nitrogen, same stuff as liquid nitrogen, but at room temperature and in gas form. Not for cooling, but to protect the inside of the pen.
      A normal pen uses gravity to push the ink in the pen towards the tip of the pen.
      The space pen is able to write in 0 gravity and in negative gravity (upside down). Instead of gravity, the ink is pushed by a gas under pressure. It's the gas that pushes the ink not gravity.
      In principle, you could put the pen under pressure with any gasses. But some gasses react with other chemicals, air is an oxidiser and will rust metals. And a few gasses are inert, do not react and are stable (does not change over time to something else). One of those inert gasses is nitrogen and it's cheap. So they used that to put the pen under pressure and protect the inside of the pen. If they used air the ink, metal, oil, ... would oxidise.
      In the food industry they use argon gas, also an inert gas, to protect food. Food packed with argon gas stay longer fresh, no air for food to oxidise with.

    There's a few flaws in this video. 1. Why make a special space pen when you can just bring a pencil to space like the soviets did? A pencil is much more efficient, and the shavings can be recycled as wood or use a mechanical pencil.
    2. Why make specially machined parts for riveting aircraft when it's much easier and safer to weld the parts. A properly done weld will actually make the area stronger, not weaker like everyone falsely believes. A weld is adding metal to metal, not like adding glue.
    Human error is the only issue with welding but of you hire a good welder it's safer because the part won't break or need replacement for several years, if not ever at all, hence why the military requires their aircraft to be fully welded without riveting or fasteners of any kind. It's cheaper to weld than to specially manufacture special materials that can break easier than any weld can (a welded part would have done better on those stress tests in the video than the bolts).
    For reference, the reason why the titanic sunk was because it was made by riveting parts instead of welding it. Hence, when it hit the ice, it broke the bolts, and the steel plates fell apart. If it were welded, this wouldn't have happened, and it would have just barely scratched the metal plates, and it would have survived the journey.
    A modern example is that the Boeing planes are failing BECAUSE they didn't want to pay welders enough so they all quit so they had to use riveting and fasteners so the plane parts fail BECAUSE THEY ARE NOT WELDED. That's why the military requires welded parts, and most state laws do now as well.

    • @HDL_CinC_Dragon
      @HDL_CinC_Dragon 6 หลายเดือนก่อน +1

      On the pen, it's because the graphite in pencils is electrically conductive so using one in space where it can get everywhere due to low/no gravity leads to catastrophic electrical failures. That's why the soviets started using the space pen too immediately after we created it.

    • @resurgam_b7
      @resurgam_b7 8 หลายเดือนก่อน +7

      No, they didn't. Pencils present a wide range of issues that make them unsuitable for space flight. The most readily apparent being the issue of sharpening, when a pencil is sharpened, it produces a lot of fine graphite dust and wood shavings which are difficult to contain. Sure, a sharpener with a shaving catcher could be used, but have you ever used one of those that didn't let out at least a little bit of dust? That isn't a big deal in a classroom or art studio here on Earth, but in a space craft, having dust of any kind can be problematic, doubly so when it is highly conductive graphite dust. That dust production isn't limited to sharpening either, even just the act of writing and handling things that were written on can release a small amount graphite into the air, which while it is unlikely to cause huge issues, is not worth the risk when it comes to space missions. All of that said, NASA actually did use pencils on space flights prior to the development of the pen by an outside company at which point they tested and then deployed it because it was superior to pencils.
      The myth that developing the space pen cost bazillions of dollars is highly misleading. The project that the pen's introduction and testing was a part of was indeed quite expensive, but the pen wasn't the sole goal of that project, it was kind of just a tacked on addition that supplemented the rest of the work. Saying that the pen cost ridiculous mountains of money would be like saying a car windshield sun shade cost $30,000 because you wouldn't need to buy one if you didn't have a car. On top of that, it is stupendously difficult to get an accurate representation of how much space programs cost since they are so vast, interconnected and involved. Do you factor in the cost of building a safety railing on a walkway in the Vehicle Assembly Building into the "price" of a particular Space Shuttle because that railing was installed while that vehicle was being assembled, or is it associated with general maintenance and so applied to the Shuttle program as a whole and thus inconsequential to the cost of a single rocket? Is it fair to say that the cost of developing the EMU space suit was solely associated with the Shuttle Program, even though suits based on those designs are still in use on the ISS today? Politics, contracts, cross-compatibility of technologies, and many, many other factors all play into the stated cost of any particular space project, but at the end of the day, the number that is stated is really just an educated guess at the proximate cost that contributed to the project in question.
      Last but not least, Russian cosmonauts also use the space pen.

      It actually can't. Pencils present a wide range of issues that make them unsuitable for space flight. The most readily apparent being the issue of sharpening, when a pencil is sharpened, it produces a lot of fine graphite dust and wood shavings which are difficult to contain. Sure, a sharpener with a shaving catcher could be used, but have you ever used one of those that didn't let out at least a little bit of dust? That isn't a big deal in a classroom or art studio here on Earth, but in a space craft, having dust of any kind can be problematic, doubly so when it is highly conductive graphite dust. That dust production isn't limited to sharpening either, even just the act of writing and handling things that were written on can release a small amount graphite into the air, which while it is unlikely to cause huge issues, is not worth the risk when it comes to space missions. All of that said, NASA actually did use pencils on space flights prior to the development of the pen by an outside company at which point they tested and then deployed it because it was superior to pencils.
      The myth that developing the space pen cost bazillions of dollars is highly misleading. The project that the pen's introduction and testing was a part of was indeed quite expensive, but the pen wasn't the sole goal of that project, it was kind of just a tacked on addition that supplemented the rest of the work. Saying that the pen cost ridiculous mountains of money would be like saying a car windshield sun shade cost $30,000 because you wouldn't need to buy one if you didn't have a car. On top of that, it is stupendously difficult to get an accurate representation of how much space programs cost since they are so vast, interconnected and involved. Do you factor in the cost of building a safety railing on a walkway in the Vehicle Assembly Building into the "price" of a particular Space Shuttle because that railing was installed while that vehicle was being assembled, or is it associated with general maintenance and so applied to the Shuttle program as a whole and thus inconsequential to the cost of a single rocket? Is it fair to say that the cost of developing the EMU space suit was solely associated with the Shuttle Program, even though suits based on those designs are still in use on the ISS today? Politics, contracts, cross-compatibility of technologies, and many, many other factors all play into the stated cost of any particular space project, but at the end of the day, the number that is stated is really just an educated guess at the proximate cost that contributed to the project in question.

    Only idiots say "a pair of binoculars". That's like saying there are FOUR oculars (lenses close to the eyes). You don't say a pair of biplanes for a unit of aircraft with two wings or even a pair of bicycles for a unit of pedal powered mode of transportation with two wheels.

      Only insufferable pedants think that language is based purely on logic rather than convention, usage, and lexical evolution.
