You need a EM deflector strong enough to deflect particles caught in the magnetic field of earth itself to escape beyond to another planet. That means a plasma shield.

Either the world has ships with plasma shields, or they are pulling your educational leg having you think that metal can block high energy massive particles denaturing your DNA.

The Russians knew.... Why do you think they never did anything more than sputnik....?

Let me ask.... have you looked into it or are you just trying to find reasons to find why it is not a lie instead of looking for evidence that it is impossible

I guess you believe in lots of other conspiracy stories too, about other events!

The order of magnitude. We are all radiated all the time, right here on Earth. It's about how much, precisely.

Apollo Rocketed Through the Van Allen Belts

The atmosphere(s) and magnetic field of the planet deflects most radiation incident upon earth. What does make it to earth are usually photons, neutrinos and very low concentrations of ionizing radiation (<<1 proton/cm^3.)

This is not the case in the Van Allen belts. The flux of ionizing particles there is much greater (~1-2/cm^3), and must be deflected in the same way Cern deflects and directs protons - with variations in EM fields.

A non-plasma metal does not have a lattice structure tight enough to prevent ionizing radiation from penetrating the hull - which means you, and other things inside the ship will capture these particles.

Either we have plasma technology to deflect these particles now, or we have never been outside of the planet - unless the world has some other technology they want to admit to (like jump machines/interdimensional stargates.)

The reason you count the consecutive days of astronauts in (be)low orbit is because there is enough ionizing radiation in that shell to cause severe aging and problems (i.e. it penetrates the metal, and denatures DNA.)

Here is the question again:

Have you investigated the evidence for both sides OR Do you just go with the information that they have been feeding you since you were a kid?

If you just continue to deny a new view without investigating it for yourself................you are only perpetuating something that someone else told you. You are only regurgitating other peoples views to argue against my view.

You have view of your own. You have the view of someone else and are perpetuating their view without actually looking at it for yourself.

Now.... this statement makes me scratch my head...

Look at the logic:

1/ I profess to have a certain view that others here disagree with.
2/ Your conclusion is that I must, then, have other views that are controversial...

This is called assumption and speculation.

Fact is... I have the ability to look at the evidence and decide for myself that something I have been told "forever" is wrong. There are many things that I still believe. This is only because the evidence still shows them to be truth.

There is no rule that says "If you believe this conspiracy theory... you must believe them all".

Yet, this is what you are assuming.

If you have an error in a detail, do you want someone to point it out in a friendly way? I haven't known anyone in the sciences that hasn't occasionally had an error they had to correct.

He owns a Boring company and a Solar one and one to do with brain research. The earth based challenges of solar power and public transit systems are also complementary to the kinds of technology development needed for Mars
Tunneling will be a very important part of space colonization to be sure. Underground structures make a lot more sense long term than the shiny dome tent thingies.
I vote SpaceX making it there first. They've got the technology, the drive and most importantly, the celebrity billionaire fundraiser to pull it off.
It's going to be very interesting when a branch of humanity and their new home world are established and run by a corporation. Will SpaceX "own" Mars? Or try to? What happens when Disney tries to set up a colony?

The future of space exploration/mining is AI and robots not people. And I think earth is going to run out of resources before even tat becomes feasible.

I would have liked to see a moon colony too and it may still happen. The moon is an easier tourist destination. I do not think a Mars initiative and a moon one are mutually exclusive - especially regarding the rocket lift capability. But the money and interest seem to be with Mars right now. Also the moon and Mars bases are different kinds of challenge. If ,as I believe Musk has suggested ,the journey time is as low as 30 days and if the Mars bases are properly shielded or underground, radiation might not be such a massive barrier to success.

Peoples eyesight was damaged in zero gravity on ISS for reasons that are understood. But Mars has partial gravity (.38 g i think) so it is a different case. But still needs research.

Good post and questions. A government base would probably have a definite code of rules and earth based command structure. A corporation that makes its money out of getting people there would have to make some effort to make the destination palatable to keep the. Customers coming. Would the base itself be more wild west than East coast - do not know. Not sure how freedom works on Mars. If you leave the colony to strike off on your own your survival chances are slim without substantial resources so I suppose individualism is less attractive there. That ability to thrive will require a strong Martian manufacturing, construction, food supply and transport concept.

There is no point to space unless it benefits human beings. There is big money to be made from tourism, mining and energy sectors. Once these are mobilised resources might become cheap and plentiful. It is life and the green stuff that is short supply out there. The Saturn moon Enceladus is mainly water ice for instance but only some 5% of the water mass of the earths oceans

I agree It would be better to use the moon as a launch site to mars, since there is less gravitational resistance. It would be cheaper in the long run.

...It seems like it was just 'meant-to-be'.

Here, go to the 3:30 minute mark if you don't want to waste too much time. This is a NASA engineer stating that we cannot send humans up this far and must "solve this problem before we send people to this region of space".

YouTube I suspect.
Oh, man... you say that like "YouTube" is a being, an entity.... sheesh... how long is it going to be before people realize that YouTube is for cat videos, crazy pranks, serious presentations, and everything else under the sun....

I guess that an engineer from NASA cannot be believed if they are on YouTube but totally believable if they are in a classroom... Oh Ya.. unless that classroom session is posted on YouTube, then it is a lie...


Wake up people... YouTube is a source of everything... truth, humor and everything else. Don't use "they saw it on YouTube as a reason to discredit their evidence.

Nobody or no robot or no satellite is going to space. The temperatures of space are extreme and will fry any electronics, and melt circuit boards..... Unless you know how your cell phone would last in an oven at 250 degrees Fahrenheit or function at minus 148 degrees Fahrenheit.

This solar radiation heats the space near Earth to 393.15 kelvins (120 degrees Celsius or 248 degrees Fahrenheit) or higher, while shaded objects plummet to temperatures lower than 173.5 kelvins (minus 100 degrees Celsius or minus 148 degrees Fahrenheit).

from: The Temperatures of Outer Space Around the Earth

Astronomers tell us that the solar wind and interstellar gas clouds are over a thousand degrees and sometimes in the millions, but also that the cosmic background temperature is minus 455 degrees Fahrenheit. A thermometer in space will read somewhere between these two extremes, depending on whether it's in the sun or the shade.

From: What's the Temperature in Outer Space?

All those satellite dishes are a vast hoax, then...

He said space, not (LOW) orbit within the Van Allen belts.

And, satellites do fail when they reach a "dead" zone in which they are inadvertently exposed to ionizing radiation. Signals (EM waves) can be perturbed by the scattering energy of ionizing radiation.
