Drudge Retort: The Other Side of the News
Friday, October 14, 2016

Spending extended time in space wreaks havoc on the body. You lose bone density. Your muscles waste away. And according to a new study published Monday in the journal Scientific Reports, you also may get "space brain," a form of brain damage caused by galactic cosmic ray radiation -- and it could be a barrier in the pursuit of colonizing Mars. In a preclinical rodent study performed by Charles Limoli and his team at the University of California, Irvine, researchers found that radiation exposure equivalent to the radiation experienced in space caused long-term brain damage to rodents, leaving them with cognitive impairment and dementia. Most surprising, Limoli said, was how persistent the damage to the animals' cells actually was. "In most cells there's a level of recovery," he said on a phone call Monday. "We followed up six weeks, 24 weeks later. The changes don't resolve."

Permanent cognitive impairment comes with an alarming side effect: the loss of "fear extinction," a tool the brain uses to suppress traumatic events.

"It's like if you hear a car horn and you associate that with an oncoming car -- that's a problem in a crosswalk," Limoli said. "But if you hear it in your house, [fear extinction] will cause you to freak out because you can't dissociate that the car isn't in your living room."

Astronauts on the International Space Station are still protected by the Earth's magnetosphere, so the radiation isn't as destructive. According to Limoli, the only humans who might have experienced equivalent radiation are the astronauts who went to the moon -- and that's a very small sample size.

A much larger sample size is needed if we are to treat this condition with any success.

And no... nobody is going to Mars any time soon.

I am positive that science will be able to compensate for this in the future.

You'd have to be brain damaged to want to "colonize" Mars using available (or even soon to be available) technology anyway.

It goes beyond cosmic radiation, simply being in zero gravity is an issue:

Study Reveals Immune System is Dazed and Confused During Spaceflight
There is nothing like a head cold to make us feel a little dazed. We get things like colds and the flu because of changes in our immune system. Researchers have a good idea what causes immune system changes on Earth -- think stress, inadequate sleep and improper nutrition. But the results of two NASA collaborative investigations -- Validation of Procedures for Monitoring Crewmember Immune Function (Integrated Immune) and Clinical Nutrition Assessment of ISS Astronauts, SMO-016E (Clinical Nutrition Assessment) -- recently published in the Journal of Interferon & Cytokine Research suggest that spaceflight may temporarily alter the immune system of crew members flying long duration missions aboard the International Space Station. This is of concern as NASA looks ahead to six-month and multiple-year missions to asteroids, the moon and Mars because something as simple as a cold or the flu can be risky business in space.

AND also, there, too:

More than half of American astronauts experience vision changes and anatomical alterations to parts of their eyes during and after long-duration spaceflight. It is hypothesized that the headward fluid shift that occurs during space flight leads to increased pressure in the brain, which may push on the back of the eye, causing it to change shape. The Fluid Shifts Before, During, and After Prolonged Space Flight and Their Association with Intracranial Pressure and Visual Impairment (Fluid Shifts) investigation measures how much fluid shifts from the lower body to the upper body, in or out of cells and blood vessels, and determines the impact these shifts have on fluid pressure in the head, changes in vision and eye structures.

Reproducing the effects of gravity is relatively simple with a large enough ship.

True, but we're decades away from that. And then once we get to the Moon or Mars...

At just 0.38 of the Earth standard, a person who weighs 100 kg on Earth would weigh only 38 kg on Mars.

things on the Moon will weigh only 16.6% of what they weigh on the Earth.

Space most likely Fake everything the produce is BS.

The mars Rover has instant communication but it takes 12-27 mins to reach mars.

NASA has 3 times faster then light communication now?

You can't really be this stupid.

Prob same guy's who wonder if there is water on mars.

This one always made my laugh!

Try looking on the north or south pole with the ice caps the size of Earth not on the desert equator.

And i'm not even a Nasa employee or a scientist

Light to reach mars 300,000 KM per Sec 12-27 mins Earth Distant At light Speed is 2-20 mins Depending ON orbits far side middle or near.

And Radio Communication (Radio Waves) Travel around 280,000 KM and lose % on the Speed Factor.

And that effects communications as well.

Those speeds listed are 10-15% faster and perfect conditions.

You know that Mars is Fake too, right? It's all Fake. Space is Fake. The sky is a dome and the stars and planets are just pasted on it.

And English is your second language right?

Anybody with two cents worth of brains would establish a moon colony and make that work before going to Mars. But then politics has nothing to do with thinking clearly or doing the rights thing. It's about lying and stealing.

SO the study was not done is space.........

Its clear whats going on they canceled man in space so they could do junk science research.
Now they are trying to come up with some junk studies to stop man from going back into space after Obama is gone.

Where are the studies of actual people? It doesn't exist.

Of course not. I don't take stupid risks. For example I don't get into people's faces at the gun range.

And since when are you the sole arbiter of such issues surrounding spaceflight,

Since I spoke and you listened.

" I don't take stupid risks. For example I don't get into people's faces at the gun range."

That's because you are obviously part of the problem.

If you See something Say something. How hard is that? (tho one would hope you were at least smart enough not to get in someone's face who is holding a loaded gun)

Good thing our greatest explorers and so many among us do not accept that kind of defeatist philosophy. Or we would be living in the Dark Ages like so many Muslim countries today.

You know...like Pakistan.

How hard is not being stupid?

Very hard, I guess, because you sure can't get the hang of it.

like Pakistan

Thank goodness you didn't say "like Texas"... or we would be having a problem, you and I.

Long Space Flights Cause Permanent Brain Damage

but let's not discount the fact that the Short Space Flight I took last night also is highly susceptable to causing major brain damage...

i'm just here to help.

ISF astronauts are protected by the magnetosphere. If only there were some way to generate an artificial magnetic field to draw the charged particles away from their living quarters........

Same for any cutting edge exploration at any time in the past.

First few missions guaranteed to have some level of failure but being first definitely puts you in amazing company, ie Neal Armstrong, Alan Shepard, Ferdinand Magellan ect.

So I guess space scientists need to figure out how to make artificial gravity for long space flights.

Those people took huge risks but they had some expectation of being able to come back alive.

If you go to Mars, that's it. The rest of your life is going to be spent on Mars. And you're not going to be doing much exploring once you get there. I don't see how the novelty doesn't wear off quickly.
