    A correction is in order as I said the gateway program was cancelled, this is not the case and it is due to be in place by the time of the Artemis program in 2024.

      Also, a 10-Gy whole-body dose of ionizing radiation would result in almost certain death within 24-48 hours, with or without a bone marrow transplant and supportive care. Anything above 8 Grays is generally regarded as invariably fatal, and 10 is definitely in that territory. A dose of 4-6 Grays is generally where doctors and specialists try to do intensive interventions like colony stimulating factors, marrow transplants, and so on. Anything in the 10 Gy range would probably just be met with palliative care-- I believe that one's chance of survival at that high of a dose is something like less than one tenth of one percent, and that's *with* aggressive interventions. Then again, a lot of the events that have informed our medical knowledge of acute radiation sickness have been multiple-casualty in nature, Chernobyl, Hiroshima/Nagasaki, Castle Bravo fallout, and so on, meaning that such medicines were maybe reserved for those who the doctors thought had the best chance of survival. If it were just a one-victim event, maybe they'd get the kitchen sink thrown at their ARS, I just don't know.
      Just thought I'd add in that thought about 10 Grays being a tad more serious than you made it sound, thanks for the great video

      That's unfortunate. The gateway program is a waste of effort. Spacecraft should be able to go directly to the Moon without any steppingstones. The Moon itself is the practical steppingstone for missions further out.

    • @Shazprime
      @Shazprime 3 роки тому +6

      @@MrVillabolo Well, in order to prep the Moon to be that stepping stone, you might need the Gateway as an interim step, no? But in all seriousness, there are so many reasons why all the manned missions put on or designed for TLI have been 2-spacecraft (orbiting tug + lunar lander)-- If you need to land your whole stack on the Moon, that means you need to carry enough fuel to lift the entire stack off the Moon again, and you need to have the whole stack certified for the entire complex process of launch, TLI, lunar landing, lunar ascent, and TEI, as well as being itself certified for reentry or having a second capsule anyway for reentry. It is orders of magnitude cheaper to break the stack into discrete pieces, each of which is designed for the environment and workload of each step in the mission. Imagine if you had to have a command and service module (CSM) that was designed not only to accomplish the big navigational burn to get back to Earth (TEI) (The reason I didn't include TLI is because the Apollo missions used the S-IVB third stage to perform its TLI burn, and I assume that Project Artemis will also use a stage to accomplish it too), as well as keep the crew safe in deep space for a week or more, and carry enough consumables for both the trip there and back, but ALSO be rigorously certified for lunar landings and ascents, as well as moderate-to-long duration stays on the lunar surface. Yikes. I know we've come a long way in materials science, engineering, rocketry, and a whole bunch of other things, but even to a casual observer this seems like an unrealistic vision. Also, such a spacecraft would almost certainly be expendable (i.e., not re-usable), so this ship, which would almost certainly be the most expensive spacecraft ever built, would be thrown straight into the garbage can right after it performed its duties.
      I'm not arguing that it's impossible, I just think that it makes so much more sense to do things another way in terms of a number of variables that it would simply never happen. However, if it did, it would be cool, not gonna lie.

      One of my hobbies as a child, which is now my career, was programming our home computer.
      The first computer we had, an Acorn BBC Micro Model B, came with a mountain of detailed programmers documentation and reference material.
      Everything you needed came with the computer.
      However, our _second_ computer was an Acorn BBC Archimedes A3000
      This came with practically no programmer's documentation.
      So I could never really program it beyond what was the same between the two computers.
      Pre-Internet, so you're screwed, it's impossible without spending hundreds of pounds on documentation.
      And this ain't even know what documentation you should choose.

      It appears you don't understand what a conspiracy theory actually is.
      A conspiracy theory is a theory that involves a conspiracy.
      A conspiracy is when two or more organisms (the 'conspirators') work together for some goal.
      Conspiracy, collaboration, collusion, cooperation.
      That's it.
      Conspiracy theory does not mean ridiculous theory (a theory that is ridiculous) or false theory (a theory that is false).
      A conspiracy theory may be good theory, offering value.
      A conspiracy theory may be bad theory, offering no value.
      So what is it that makes it a conspiracy?
      The relevant question to ask is, are there two or more people involved?
      If yes, then it's a conspiracy, collaboration, collusion, cooperation.
      If not, then it is not a conspiracy.
      A baseball team conspires to beat their opponent.
      The "official US government story" about 911 is a conspiracy theory; there were more than one hijacker involved.
      Don't conspire with other idiots to keep the status quo.
      Instead, conspire with intellectuals to change the world to be a better place to live.
      Conspiracy, collaboration, collusion, cooperation.
      All REQUIRE 2 or more people.
      If you think a theory is a conspiracy theory, ASK YOURSELF, "WHO ARE THE CONSPIRATORS?"!!!
      The term, conspiracy theory was weaponized by the CIA in the mid 1960's during Operation Mockingbird, in which agents infiltrated corporate mainstream news outlets.
      This sewage was then spewed on a public lacking the cognitive abilities required to vet information.

    One minor inaccuracy. The reason we see the aurora over the magnetic poles is that the magnetic field is closer to the Earth there. The particles deflected from the magnetosphere are invisible...and the deflection is also invisible. We see light from particles that were not stopped by the magnetosphere and crashed into either oxygen or nitrogen atoms, which then glow after absorbing the energy and becoming energized plasma, like neon tubes do. The particles are not "funneled" there.

    • @paulmichaelfreedman8334
      @paulmichaelfreedman8334 3 роки тому +5

      The particles are guided along the magnetic field lines towards the poles, a fraction of which are actually guided into the atmosphere. Although funneling is technically not correct, the shape at the poles does resemble a funnel

    I have often wondered how the 1st Apollo mission dealt with the Van-Allen belt around Earth. Now I know that there is no escape from it but instead one must navigate through it to make it to the Moon and other places in the solar system. Odysseus had Scylla and Charybdis and we have cosmic radiation in myriad forms. Thank you for showing the extent of the effects of the solar flare from the 50s here on Earth. That scale of power is unimaginable when you think that it caused over 4,000 magnetically-triggered naval mines to explode within a short time of each other. Satellite circuitry was cooked, solar panels were hammered by charged particles that essentially aged them, digital communications were extensively disrupted. It's an example of how far we have to go scientifically to understand the basic mechanics of the universe...not even that, just stars as a beginning. It's humbling under no uncertain terms but awe-inspiring at the same time. It's why I like Star Trek (original series)-- their slogan wraps the whole idea up by the phrase "to boldly go, where no man has gone before."

When traversing underneath one, you saw these chucks randomly scattered. Also, eerily when camped out on the glacier you would here thuds from these icefalls.

    The SI unit is Sievert by the way, not Rem. And of course, Gray is an SI unit, but only for raw radiation which does not give the full physiological picture unlike Sievert. So there is a curious mixture of non-SI and SI units in this video, although, at least for Rem and Sievert, it is easy enough to convert them into each other.
    As an official radiation exposure worker (airline pilot) my monthly, yearly and life long exposure is measured in Sievert of course.

    Boron, lead and certain other elements also work well as radiation shields. Like hydrogen, they have what you might call "lumpy" nuclei in relation to their electron shells, which helps to capture stray neutrons flying past. Boric acid is added to the coolant in certain types of nuclear reactors, to act as a "neutron poison", and thereby calming reactions. Interestingly, polythene - simple plastic - also has a degree of effectiveness as radiation shielding, again because of the amount of hydrogen atoms it contains.

    Thank you Curious Droid for being the voice of reason during this time of ever-increasing anti-science rhetoric that is currently sweeping humanity.

    Its a sad day that Curious has to account for flat earthers in his presentation of space travel, but, alas, they seem the loudest (and thankfully) minority. Good video as usual Curious Droid🖒

      Flat Earthers are different from Moon Landing is faked conspiracy theorist. Not that I agree with any of them. Just pointing out while some may believe in both conspiracies, they don't necessarily believe in both. Flat Earthers are the worst since that is easily disproved by looking at the stars in the night sky (Polaris is a the easy one to disprove their theories). Apollo landing conspiracy you have to provide more facts to before they realize they are just dumb internet trolls.

      @@paulhaynes5029 The difference between a flat earther and a moon hoax conspirasist is the model of reality they believe in. Moan hoax believe in a spherical earth, their argument is that we did not have the technological capability to land on the moon at the time.
      A flat earther denies all reality and insist that the earth is flat. Most them use the moon hoax conspiracies to hedge the arguments.

      @@rickyecook59 its not that i want people 'thinking like me' - i want people to stop believing in nonsense. Trust science and not flat earthers on youtube or antivaxxers etc. The fact that you're defending them kinda makes you the odd one.
