If you think so, that works for me.

It is the largest moon in the Solar System. Not by much, but still :) Watching the Expanse series at the moment, where Ganymede was being used as the granary for the outer Solar System. Also mentioned that if you wanted to have healthy kids then women were sent there to give birth because of Ganymede's magnetosphere.

Isaac Arthur explained that it's actually Callisto that is best suited for bases and colonies. It lacks several severe hazards of Ganymede.

Why would its position have any advantages compared to Earth? Does it make it any closer to any other solar system? Once you leave Earth's gravity well, you better do not stop anywhere else but keep going until you get to your destination.

@@rd-gi6jw We should do it, because it's just such a great pimp thing.

@@rd-gi6jw Then again, if you wanted to launch something (or someone) to Titan, or Pluto, or the furthest reaches of the Kuiper belt, you would be much better off launching it from Ganymede as a starting point, rather than Earth. That was my point about it's position to the outer solar system. It's a much smaller gravity well than Earth, and there is plenty of water there to produce rocket fuel, drinking water and oxygen. If there were ever a permanent settlement there, it would have the potential to make a good launch point for other deep missions to the outer solar system. That potential would obviously be some distant point in the future though.

Tin foil hat helps as a deflector shield.

I would think that creating a magnetic shield like the earths that would block much of it in the same way our atmosphere does.

How about shortening the trip by way of Venus. You could knock off about 5 months off the trip with a gravity assist.

Bryan Heagy would take lots of power. Solutions they haven’t figured out yet. The power source needs to be innovated.

All that infancy training was not in vain!

That would be an honour and a privilege bestowed on a select few.

Gandalf Stormcrow Hey Gandalf, where have you lost your wisdom? They would marvel at the sight and then be crushed by the gravitation.

I think when you're used to weighing 25kg, you would feel a bit weighed down when coming here :P

There’s a movie about that FYI

Probably could not be done . Since a person born on Mar would be only accustom to about 40% of Earth’s gravitational acceleration. Their bones and muscles would not be formed during growth to handle 2.5 times the force of Mars. Just a thought.

We’d have to cross the lines of genetic modification to be successful I.e nit pick genes that would be most effective on the planet, create around 10k of these individuals, and let them terraform the planets before the mass movement of people may begin

Thats why habitats need to be under the martian surface. Orbital Habitats and surface ones can be shielded by lead and water, but only to a certain degree.

Nasa plans to use a type of structure as the Mars buildings to help protect against radiation, they're also very durable and can almost hold under pressure of some vehicles as tested, but will that be strong enough against other forces of nature on Mars? Find a playlist on my other channel called "Nasa plans to make 3D printed buildings on Mars". My comments with links in them are hidden, and so you will need to use the steps below to find my other channel. 1. Go to my channel and find the subscribed channel called Technology Research, and go there. 2. Check the "About" tab for more info, on my other channel. And please watch all the playlists on my other channel, no cherry - picking through videos and playlists, watch them from top to bottom in that order. My other channel is dedicated to help people to be aware and to help them learn about Graphene, emerging technologies and beyond, Quantum Technologies.

And since earth’s 1.7 degree temperature increase in the last century has blown our minds, how would we manage Mar’s negative 100 degree decrease in temperature.

Regarding Gravity, constant acceleration set at +-1g would resolve the gravity problem. We would fix acceleration to 1g though plus start deceleration well in advance so is all nice at 1g....

Don't worry sir we probably won't make it there

You just answered the question of why we don't see any advanced civilization in the Universe. Spoiler Alert...We're no different.

Humans are viral and behave similarly. Viruses inevitably kill their host when numerous enough. Our host is the earth and there's no place like it within lightyears. We seem to be doing a fair job of sterilizing it despite this fact. So let's press on. Though viral, humans are quite fragile. Without some serious biological re-engineering, leaving the solar system let alone inhabiting local planets & moons long term is a no go.

Isn't mars dust toxic?

@@hdaviator9181 yes. Perchlorates found in high concentration in the soil are highly toxic to humans, and the silicate in the fine dust (think talcum powder) can react in the lungs causing other toxins. Planting in the soil as described in The Martian doesn’t seem realistic to me.

@@billneo - What you say makes all sense: Lunar industrialization is needed in order to make portable homes to ship to Mars easily taking advantage of much lower Lunar gravity. Oh, wait, Lunar regolith is also bad, right? And the extremely cold nights last 15 days, right? And we can't hope to either ship fuel in sufficiently large quantities up there nor to extend sufficiently long electricity networks across the Lunar surface, right? So we are stuck with whatever batteries we can ship up there for every other forthnight... not promising for Lunar industrialization prospects, honestly. So, how?

@@292Nigel pffft it won't

@@billl605 Well that's OK then.

Ditto. Also energy and general material transportation issues, poisonous Martian soil, etc.

A simple rear shielding of water-ice would suffice. This would be between the craft and the Sun, of course. . . . At approach to mars, it would be jettisoned, and useable at the destination.

skywatcher1972 , Wouldn’t water actually become radioactive after enough exposure? Personally, I think the best option is the strong magnetic field around the craft.

@@KeepItReal33 water is used in nuclear plants to keep the spent fuel rods from emitting radiation into the environment untill a permanent facility is built to store them,,, it's a great absorber of radiation... Cant see the magnetic field idea working as it would require way too much energy

Darren Murphy , Yes. Water is a great “absorber” of radiation and the water in nuclear power plants is radioactive. That’s why I asked the question. Until we develop some sort of field to block most, if not all, of radiation, our presence in space will be limited and hampered. On a different subject, I don’t really see humans spending a great amount of time on Mars or even the Moon. The gravity is far too low and will have devastating effects on the human body. That is another problem we need to solve.

@@KeepItReal33 yes, but it does not leak radiation into the surrounding environment, the pools of water used to house the spent fuel rods are in the vicinity of the workers at the plant, so I assume it's quite safe to be around, provided the water doesn't evaporate...I can't understand the reasoning for wanting to go to Mars, there is nothing there, maybe evidence of a past civilisation from eons ago, but that's about all,,, I know it's all on the name of finding our feet and hoping we are successful to hopefully leave the planet one day should the sun go supernova,,, but our problems here on Earth need sorting out first, before we poison any other part of the universe with our society... If we get to Mars and set up a successful colony,,, then martianborn people will evolve to cope,,,, it's the first ones there that may have issues,,,,we don't even know what living on another celestial body does to us there could be any number of different variables that could jeopardize our stay

Dont hold your breath

With NASA in charge, we'll be SOL. In my lifetime, NASA has managed to blow up 2 space craft and regress to having NO way to get astronauts into LEO.

After liftoff the spaceship rotates around the Earth while trump builds a wall around it.

But in reality that could never happen. You can't come before you leave. It's just that information that you left would come after you have already returned. Basically, it's like watching a boxing match that happens on Earth, but you're on Jupiter. The match has ended and the winner is known... just not to you. So you can still bet, because nobody else on Jupiter knows the result, not even the betting place.

Not really. Once spacex gets starship running experiments in space or on the moon will become easy to conduct. The biggest hurdle in getting people at least to mars is going to be radiation protection. You cant get there if your astronauts are dying from radiation poisoning, which will happen en route if there is no solution.

@@kimjunguny I'm going to assume that radiation is if not solved, its on the way to being solved. Why? Because Elon wants to go to Mars. And he's not stupid enough to even try if he can't solve that problem.

Agree. At the rate of advancement in AI and robotics, it just makes sense to send probes instead.

With over 19 years' experience occupying the ISS and the new heavy lift rockets coming out, the food and water and life support gases are the "easy" part of such a trip. We can do that. We've kept individuals in space for many months at a time. We can easily assemble-in-space a large enough ship to get to Mars and back. We can pre-stage a lot of supplies on Mars' surface in advance at the intended landing site so the crew doesn't have to carry it all with them. These are all "stretch challenges" with existing technology, but quite doable. The much bigger problem, by far, is the radiation-in-transit problem. And I think a big part of the solution is to make fortified, hardened sleeping spaces that can be retreated to during solar activity -- much easier than fortifying the entire crew module. Gotta stay in your bunk rack for a few days? Equip the bunk racks for mild to medium sedation to ease the cramped-up times. After you solve for radiation, turn your attention to non-gravity. So far, wayyyyyyy underdeveloped is any kind of spun structures capable of providing gravity needed for such a long trip. Do we need a full 1 G? Doubt it! Even 1/2 G is better than no G.

Seriously, though, every time I see something about colonizing Mars, it's all about 3D printed habitats or domes. I think a subterranean habitat would be better. You have the crust/regolith above you as a shield, and depending on the rock you're in, all you need to do is seal up the ends of the excavation. We currently use tunneling machines, here on Earth, that as they dig, they take the excavated material and turn it into wall panels and install them as the machine moves forward. Why not deploy such a system on Mars, or even the Moon. As problematic as the book was, "The Moon is a Harsh Mistress" did have a lot of really good ideas about how to build and maintain a space colony.

@@dernudel1615 In Futurama, our heroes enter the Mars underground through the Face of Mars. Later on, they emerge from the Ass of Mars.

Totally agree that we first need to experiment with living on our moon for many years and experience all the trials & tribulations on it before we even think we can put people on Mars.....Because if we hurry up and try to put people on Mars it will be a complete disaster.....It's ludicrous to even think we are smart enough to do that.....We aren't!

@@georgesealy4706 It is easier to overcome the radiation problem in robots than biology of course, but it is still a very significant problem. This is part of why the rovers have very low intensity missions that last for years.

We are in a galactic pin ball machine... nothing new. The planet was created by those things hurling through the universe. Jupiter tends to pull most object toward itself, kind of the guardian of the area. It is inevitable that earth will get hit again though.

I agree. Humanity is too worried about pity wars and racial superiority. We should be turning our focus to conquer and secure our species.

@@xtscarfacem8255 You're thinking small. The issue is economics. The cost for traveling great distances in space are extremely high, and the reward is non-existent, while the risks literally include death.

Unfortunately, you are likely substantially correct about that. It is easy to convince politicians to vote for trillions of dollars to build nuclear weapons to end civilization, but extremely difficult to convince them to pony up for moving our civilization (such as it is) to the stars (or for just avoiding turning Earth into kind of a pale imitation of Venus, say at 200 as opposed to 800 degrees F.). It's therefore no wonder that the space aliens haven't paid us a visit...

It would work on the moon as well and we need to practice on the moon before we try Mars and build the space ships on the moon then size won't matter and neither will shape

It’s significantly harder to build a settlement underground than it is on the surface. I’m no expert but the only way that seems practical is if there was already a stable cavern underground that could be used and converted into a settlement. We would probably already need to have a permanent presence on a planet before we could start construction on an underground human settlement.

@@atsylor5549 Tunneling is 19th C tech. End of story.

@@TheLunacyofOurTimes do you realize how long it took them to build tunnels in the 19th century? And the first people to colonize a new planet will be scientists and various experts not laborers. And before you think machines you should look into the size and weight of mining equipment. Like I said before you’d already have to have a permanent presence before building any significant underground structure. But you feel free to think that’s a doable first step.

@@atsylor5549 Limited thinking. A window to a Mars transit only opens briefly every 2 years. Of course initial residents would be highly and muli-qualified scientists and engineers. The first residents should be robots who can get a head start on what will be needed. Scientists are not going to spend 12 hours each day digging a tunnel.

The nearest star to ours - Proxima Centauri - is about 4 and a quarter light years away. With the fastest propulsion systems we have now for space craft - it would take 80,000 years to travel that distance. But on the bright side - if we can make space craft that go twice as fast as we have now - we cut that travel time down to a very reasonable 40,000 years.

Reminds me of the Terra Nova episode of Star Trek Enterprise. Just after Earth got warp drive they sent out a colony ship on a mission to colonize a planet. Getting there took like 20 years. By the time Enterprise got there many years later, the decendents of the colonists had changed quite a bit. And didn't consider themselves Earthers anymore.

@@SandsOfArrakis They always did explore very compelling social and ethical questions.

but we are at the top of the complexity pyramid. So we are kind of a big deal even if our mass is small

No need to bring fuel up. Extract hydrogen on oxygen from Phobos and Deimos at Mars and from the Moon back at Earth.

Yes you are right. But more mass means more fuel needed. If Starship brings fuel up to orbit so cheaply as Musk promise that will not be a problem. So it is possible to have a decent shielding but it increases cost.

On a space ship, the fission is used to heat ... what? You need to heat a propellant (like water) to be ejected for thrust. The problem is that there would be only a finite amount of the propellant of choice, thereby limiting the usefulness of fission ... at least at this time. Although it has extremely slow acceleration, ion propulsion is a proven technology where you can run your "engine" for quite a long time before needing more xenon propellant. Just my 2 cents.

I think it will be essential for long space journeys, such as a trip to Mars. It shouldn't be too difficult either. All you need is tethered units. Ideally, you'd want a minimum of three. That way, docking and undocking can take place in the central unit while the whole thing is still rotating - no need to stop the rotation at any time. It could remain as an orbiter while a landing vessel makes the trip to and from the surface.

That's even more of a stretch than an artificial magnetic field. None of the designs are practical enough yet.

@@Speed001 Spinning up a rotating cylinder is feasible. The current plans are all insanely expensive because they intend to build everything at the bottom of Earth's gravity well and lift it into orbit for final assembly. The first step to anything other than a "road trip" to plant a flag and head home should involve a permanently manned manufacturing facility in orbit or at a Lagrange point using raw materials from the moon.

Artificial gravity has a number of very huge barriers, and the physics of it is not even viable from a theoretical standpoint yet. The physics of Gravity as a force is very isolated from the other fundamental forces of classical physics, and so in order to crack artificial gravity, you would have to generate a grand unified field theory that links gravitation to the other fundamental forces that we have already mastered. Once that is figured out, now you can proceed to design devices that can manipulate the gravitational field and can either amplify it or attenuate it at will and in a controlled and predictable manner. And furthermore, a device that can make use of the other forces which we already know how to operate such as electromagnetics in order to generate a gravitational field of a definite strength and a defined sphere of influence. Only then can artificial gravity become a reality. It may take several Einstein-level geniuses to crack all this.

@skem Oh, it's just I've heard that with the solar cycles getting weaker & weaker it's allowed in more cosmic rays into Earths atmosphere?

@skem Indeed. But the heliosphere does and when that weakens it lets more cosmic rays penetrate deeper into the central solar system.

Science Junkie 5 by 5 No, it doesn’t. Relax. There are lots of ways to learn about physics to understand for yourself, but the short version is that no, radiation exposure on Earth is not increasing. That was an issue twenty years ago due to ozone depletion (different to climate change), but as humanity has stopped using certain polluting chemicals, the ozone has begun to repair itself.

Have them taken out before you go and put back in when you get back.

Nah just mail them to mars

In the interest of science they can have my 82 honda civic.

@IamtheFleecer mars is more or less made of rust
