While you could try to mimic the Earth's core with natural magnets, you'd be better off using electromagnets for protection.

Better invest in nuclear thermal rockets which reduce travel times to Mars. We should send crew and cargo separately - crew faster and cargo slower to reduce radiation risks
A really good episode. History shows that only HUGE amounts of radiation in a very short time will likely cause you to die prematurely. Airline pilots flying above 30,000 ft for 20+ hours/week receive a LOT of additional radiation but it does not appear to shorten their lives. Low (Moon/Mars) or zero (ISS/in- transit) GRAVITY is MUCH more dangerous to human health.
At the age of 52, I would gladly risk everything to go to Mars. I've had 9 x-rays in the last year. I don't run from those and I certainly wouldn't run from a chance to go to the Moon or Mars. BTW, for those that don't know, we get hit by cosmic rays all the time here at the surface. In most cases they pass right through us and we never even know it....
You say its not really that dangerous, but you also said we do not know much cosmic rays, so yeah... we do not know. The trip with our current understanding may just cook the astronauts. New territory here! Also weightlessness alone will make the astronauts so weak after a long journey to mars they may be almost useless when they get there.
Wrong Marcus.L. We know a great deal about cosmic rays. There are records and measurements recorded from many robotic missions since the moon. Cosmic rays are almost like clockwork. What we can't predict so well are solar storms from our sun which are variable. Luckily, we can measure them as they happen with various instruments out in space and have the astronauts take cover in shelters. We can communicate much faster than solar storms travel through space.
Great Video Marcus. What I don't understand is that people believe the science on the Van Allen belts but don't believe the science on how we can - do limit the exposure.
I very much miss your KSP videos, especially the Galileo series you started. But to reply to your question about my willingness to expose myself to radiation in order to explore space, I would absolutely do so. I'm 45 with 3 kids, so my contribution to the gene pool is secured. I'd go through the Van Allen belts and through the void between planets anytime.
@@MarcusHouse In the video in which you made a reuseable moon transfer vehicle, you said that you would make a refuler for it. can you please make a video about that re-fuler?
Good informative, relevant and succinct video! There are also many examples of science fiction writing that delve into the complexities of protection from radiation. One of my favorites is Kim Robinson's "Mars Trilogy".

Does Mars have anything similar to the Van Allen Belts? How to they intend to block long term exposure to solar and background radiation when on a long term base mission (ie Mars and SpaceX)?
I think you speak boldly about things that we have scant data on. We know how some healthy human bodies react to radiation both on Earth and also on short term trips to the moon but we really don’t measure the radiation on the exploitation trips about our solar system. It worries me that we might fail to research the safety of space travel on humans before we extend our reach beyond the moon. It also worries me that there is a commercial driver behind returning to the moon. I can imagine my grandchildren looking up at the moon and not seeing the bunny rabbit or the Man in the Moon we picked out as kids because the craters Have all been leveled for their “promising mineral content “ we don’t need to leave the planet we need to maintain it better. Whether we lose the ice caps, suffer deforestation and desertification, or have an Ice age or cataclysmic cosmic visitor, this planet holds far more promise than any other in our solar system and it’s just Grandstanding to think Mars is worth a fraction of our home planet .....
Great video Marcus, thanks for putting the time and effort in. At 12:47 in the video you mention a solar storm shelter to protect astronauts from solar radiation. HDPE may be a good material for blocking Beta particles but the "HD" stands for high-density and a high density shield will require a lot of fuel to move it if there's much of it. Even if the HDPE shield is light enough to carry all the way to mars, will it protect astronauts from cosmic rays, or will there need to be another shield material?
@@thomaswijgerse723 Mostly the unsolved problem of final storage is the reason that tops nuclear reactors from being built. Also no company would ever build a nuclear reactor without massiv help from government. The insurance alone would be unaffordable.

Excellent and informative video. At my age, 68, I would certainly take the radiation risk to go to the moon at least and support the discomforts of microgravity. Wouldn't care to deal with the still IMO primitive hygienic accommodations offered for astronauts. An earth side porta potty is nearly as good as a multimillion $$space toilet. Wet wipes as a substitute for a shower just doesn't cut it. Kudos to those who will endure the dangers and discomforts in the name of exploration.
I've read a summary I think which was a little inconclusive. Tests were done on mice from memory. Psychological issues related to tests are difficult as it is hard to rule out the tests or environment as the factors that caused the harm. It is not unlikely to me that there would be psychological issues with a Mars trip regardless of radiation exposure. It is a long time to be in tight spaces with a lot of people in a very high pressure role.
Wow, this attracted quite the collection of crazy. The full dose for a Mars mission, using chemical rockets, without one of the fancy new tricks with em fields is high.

Why not use a high powered electromagnetic field as a shield against cosmic rays? And yes, I would likely go to Mars if I could. I would rather get a Starship rigged for mining and go hunt down an asteroid....
@@markgarin6355 we exist in a gigantic electromagnetic field here on Earth and our hemoglobin seems just fine with it, thank you. Oh, and it has a good possibility of working.
@@markgarin6355 Life on the Earth's surface is protected from galactic cosmic rays by a number of factors: The Earth's atmosphere is opaque to primary cosmic rays with energies below about 1 gigaelectron volt (GeV), so only secondary radiation can reach the surface. The secondary radiation is also attenuated by absorption in the atmosphere, as well as by radioactive decay in flight of some particles, such as muons. Particles entering from a direction far from the zenith are especially attenuated. The world's population receives an average of 0.4 millisieverts (mSv) of cosmic radiation annually (separate from other sources of radiation exposure like inhaled radon) due to atmospheric shielding. At 12 km altitude, above most of the atmosphere's protection, radiation as an annual rate rises to 20 mSv at the equator to 50-120 mSv at the poles, varying between solar maximum and minimum conditions. Missions beyond low Earth orbit transit the Van Allen radiation belts. Thus they may need to be shielded against exposure to cosmic rays, Van Allen radiation, or solar flares. The region between two and four Earth radii lies between the two radiation belts and is sometimes referred to as the "safe zone". The interplanetary magnetic field, embedded in the solar wind, also deflects cosmic rays. As a result, cosmic ray fluxes within the heliopause are inversely correlated with the solar cycle. Electromagnetic radiation created by lightning in clouds only a few miles high can create a safe zone in the Van Allen radiation belts that surround the earth. This zone, known as the "Van Allen Belt slot", may be a safe haven for satellites in medium Earth orbits (MEOs), protecting them from the Sun's intense radiation.
We only need a magnetic fueld of 1 guass or 100 microteslas to protect the ship. Cos thats the same as earth right. You could do that with a smal electromagnet right. What the problem.. you dont need to absorp all radiation. Just deflect it enough. And only need to absorp stray ones..
We should allow people to risk, if you tell them real risk. So person going to Mars should know risk, and if he not see problem in it, why internet people see?
Ah but particles, alpha or beta are normally considered a threat as they go from source...to somewhere else, hitting and threat based on speed and particle size. If they are just hanging out and not moving.... what's the threat? I ran into a hydrogen atom earlier and I feel fine.
bingo_fuel- I am one step ahead of you. Immediately after my last comment I reached out to SpaceX. I am supposed to be getting my SpaceX space suit next month.
@@FutureMartian97 Yup. A 1 pack a day smoker gets about 60mSv every year. Astonauts on Apollo 14 (the highest radiation dose by far) get 14mSv on the entire trip and everyone loses their F'ing mind! 😆
Unfortunately science atm is in a bit of denial about magnetism amd electric currents in space. Whic clearly do exist i.e.van allen belts. We first need to encourage study of electric fueld in space as they may be safe place to travel due to their ability to influence particles. And shield spacecraft in a similar fashion to earths magnetic field..
@@willyouwright Not only the streangth of a magnetic field matters, but also its size. The magnetic field of earth is weak but extensive. Particles are deflected because they travel so long in this field. So you either need a huge field, or a powerful one.
@@3gunslingers your an idiot. In outer space. A field is massive as it has nothing to impede it. The size if a magnetic field is dependant on other fields around it. Ps. Any field is infinitely large..what makes the deflection is the mass of the magnet. What would happen is the mass of the ship and the mass of the solar flare would act on each other. The larger would deflect the smaller. Consider a large havy coil and a small coil of equal strength. The larger coil would delfect the smaller..
It would be more thorough of you if you had also made the exposure values from the sun's rays and cosmic rays in the same way as you showed it for the Van Allen Belt.
Highly misleading! Nice of you to forget to discuss Gamma and Neutron radiation when discussing types of radiation, the only types of radiation anyone is worried about. The sun produces gamma rays (basically the same as cosmic rays) when there are solar flares (CME's) fortunately this is directional, dissipates through space and doesn't occur all the time. Gamma rays are the radiation people use lead lining for but on the moon landing they used a gold Mylar like material to encapsulate the cabin to reduce exposure and I image the new gold foam insulators would be used for a trip to Mars, same reason space suites have gold linings on the visor.
You just know that Elon is working on a way to use the stainless steel hull to create some kind of magnetic field too repulse charged particles to protect his astronauts!
The irony is that nuclear rockets can get us from point A to B much faster in deep space than chemical rockets avoiding harmful exposure. Btw what's with the Yankee pronunciation of aluminium?
The guy who discovered it originally called it Alumium, then called it Aluminum. This is the point where Americans first heard about it. He later changed the name again to Aluminium, which is currently used in Britain. So the Americans aren't _wrong,_ they just never changed to fit with the newer name.
The most laughable part of the fake Apollo mission is the re-entry into Earth's atmosphere. The capsule travelling at about 24000 mph is somehow magically braked by the almost non existent atmosphere while being dragged down by gravity. Using their "massive" onboard computing power and "limitless" fuel they were able to calculate and execute a never done before manoeuvre to somehow skip along the outer atmosphere to slow down. Totally hilarious. Wake up people.

The world's population receives an average of 0.4 millisieverts (mSv) of cosmic radiation annually (separate from other sources of radiation exposure like inhaled radon) due to atmospheric shielding. At 12 km altitude, above most of the atmosphere's protection, radiation as an annual rate rises to 20 mSv at the equator to 50-120 mSv at the poles, varying between solar maximum and minimum conditions.
Missions beyond low Earth orbit transit the Van Allen radiation belts. Thus they may need to be shielded against exposure to cosmic rays, Van Allen radiation, or solar flares. The region between two and four Earth radii lies between the two radiation belts and is sometimes referred to as the "safe zone".
The interplanetary magnetic field, embedded in the solar wind, also deflects cosmic rays. As a result, cosmic ray fluxes within the heliopause are inversely correlated with the solar cycle.
Electromagnetic radiation created by lightning in clouds only a few miles high can create a safe zone in the Van Allen radiation belts that surround the earth. This zone, known as the "Van Allen Belt slot", may be a safe haven for satellites in medium Earth orbits (MEOs), protecting them from the Sun's intense radiation.
We only need a magnetic fueld of 1 guass or 100 microteslas to protect the ship. Cos thats the same as earth right. You could do that with a smal electromagnet right. What the problem.. you dont need to absorp all radiation. Just deflect it enough. And only need to absorp stray ones..
We should allow people to risk, if you tell them real risk. So person going to Mars should know risk, and if he not see problem in it, why internet people see?
Not a word from Elon Musk about how SpaceX will magically fly trough Van Allen Belts ?
Van Allen Belt radiation is among the least of your worries. You should be mostly worried about flying on a controlled explosion.
Rockets are pretty safe.
@@General12th Assuming the engineers did their job. Failures in rocketry are deadly though.
Anyone who claims Nagasaki or Hiroshima are proof that man didn't go to the moon have never been to Hiroshima or Nagasaki...
Ah but particles, alpha or beta are normally considered a threat as they go from source...to somewhere else, hitting and threat based on speed and particle size. If they are just hanging out and not moving.... what's the threat? I ran into a hydrogen atom earlier and I feel fine.
I sure would it's worth the risk
I would 100% go to mars or the moon. YOLO!!!
I would go 1st!! even if I die, I’ll be more famous then Neil Armstrong.
bingo_fuel- I am one step ahead of you. Immediately after my last comment I reached out to SpaceX. I am supposed to be getting my SpaceX space suit next month.
Me too. There are many people like us ready to take the risk. Exploring another planet in person outweighs all the cancers in the world.
So...not great not terrible?
Love that show. It is actually the reason I made this video. Radiation is an interesting topic and also quite missunderstood.
Marcus House Couldn’t agree more. Everyone is afraid of it yet they don’t understand that we live in a radioactive world.
@@FutureMartian97 Yup. A 1 pack a day smoker gets about 60mSv every year. Astonauts on Apollo 14 (the highest radiation dose by far) get 14mSv on the entire trip and everyone loses their F'ing mind! 😆
👍
Unfortunately science atm is in a bit of denial about magnetism amd electric currents in space. Whic clearly do exist i.e.van allen belts. We first need to encourage study of electric fueld in space as they may be safe place to travel due to their ability to influence particles. And shield spacecraft in a similar fashion to earths magnetic field..
@SkinnyFinny im listening. Please explain your view
@SkinnyFinny cool. Im really just trying to create a stir to get people to look at things we could be doing..
@@willyouwright
Not only the streangth of a magnetic field matters, but also its size.
The magnetic field of earth is weak but extensive. Particles are deflected because they travel so long in this field.
So you either need a huge field, or a powerful one.
@@3gunslingers your an idiot. In outer space. A field is massive as it has nothing to impede it. The size if a magnetic field is dependant on other fields around it. Ps. Any field is infinitely large..what makes the deflection is the mass of the magnet. What would happen is the mass of the ship and the mass of the solar flare would act on each other. The larger would deflect the smaller. Consider a large havy coil and a small coil of equal strength. The larger coil would delfect the smaller..
I would explore outside this planet, i dont care about the radiation.
I know it's hard to believe but mankind and he just getting started. in space that is, so yes we would risk it all to get to another planet .

It would be more thorough of you if
you had also made the exposure values
from the sun's rays and cosmic rays in
the same way as you showed it for
the Van Allen Belt.
do you think that they may go with just a bare dress, NASA knew it before you know..
Highly misleading! Nice of you to forget to discuss Gamma and Neutron radiation when discussing types of radiation, the only types of radiation anyone is worried about. The sun produces gamma rays (basically the same as cosmic rays) when there are solar flares (CME's) fortunately this is directional, dissipates through space and doesn't occur all the time. Gamma rays are the radiation people use lead lining for but on the moon landing they used a gold Mylar like material to encapsulate the cabin to reduce exposure and I image the new gold foam insulators would be used for a trip to Mars, same reason space suites have gold linings on the visor.
Brother do not refer nasa document, they are still in pre schooling.
Spacecraft could be better designed
Yes, Yes I would. YOLO. Its better to live and leave a legacy than fade in to obscurity or worst, mediocrity.
You just know that Elon is working on a way to use the stainless steel hull to create some kind of magnetic field too repulse charged particles to protect his astronauts!
You are correct. No where near as bad as lead, but will produce more than Aluminium.
The irony is that nuclear rockets can get us from point A to B much faster in deep space than chemical rockets avoiding harmful exposure. Btw what's with the Yankee pronunciation of aluminium?
The guy who discovered it originally called it Alumium, then called it Aluminum. This is the point where Americans first heard about it. He later changed the name again to Aluminium, which is currently used in Britain. So the Americans aren't _wrong,_ they just never changed to fit with the newer name.
If I said "Aluminium" I'd have 5X the amount of pissed off Americans telling me I said it wrong. :)
The most laughable part of the fake Apollo mission is the re-entry into Earth's atmosphere. The capsule travelling at about 24000 mph is somehow magically braked by the almost non existent atmosphere while being dragged down by gravity. Using their "massive" onboard computing power and "limitless" fuel they were able to calculate and execute a never done before manoeuvre to somehow skip along the outer atmosphere to slow down. Totally hilarious. Wake up people.
I think you mean 'wake up sheeple'
