More Difficulties If We Head To Mars

So it appears we may have to solve the issue of cosmic rays and shielding astronauts before heading to our neighboring planet. We're aware that cosmic rays pose a hazard but the extent of which has never been truly explored to this extent and the results are rather disheartening - Link

In a laboratory setting, researchers from the University of California, Irvine in the US simulated the harsh conditions of deep space by subjecting a group of mice to blasts of accelerated particles, similar to cosmic rays. The results indicated that the irradiated mice had slower response times, were forgetful, and even confused. 

"This is not positive news for astronauts deployed on a two- to three-year round trip to Mars," one of the team Charles Limoli, a professor of radiation oncology, said in a press release. "Performance decrements, memory deficits, and loss of awareness and focus during spaceflight may affect mission-critical activities, and exposure to these particles may have long-term adverse consequences to cognition throughout life."

I think they have solved it or are about to...www.universetoday.com...

Wasnt this solved with the Moon landing in the 60s with the camera and spacesuits since they lived for another 140 years

So how exactly did we get to the moon, if we haven't yet solved this problem?

Hmm....

If it's true they just went up and got exposed.

The trip to the moon was a few days. The trip to Mars could take a year. That makes a difference.

Think of getting an X-ray. Three X-rays don't put you much at risk. 365 of them would put you at risk.

Yes exactly it was just for a few days! Even the russians says, they went! Or wait they said what do you think? =/

If I was the astronaut and they told me I'd be getting the equivalent of 6 X-rays to go to the moon (3 on the way there and three on the way home), I say "let's go!".

If they told me I'd be getting the equivalent of 730 X-rays on a 2 year trip to Mars and back, I'd be like "say what...? I don't think so."

a reply to: Arbitrageur

Last I remember, an X-ray does not take 24 hours.

I wonder how a person would fair in an x-ray machine for 3 days.

I'd say not getting eaten by the draco's there and being used as an offering by the corporations or something would be number one on anyone's list. We're already there.

No - an x-ray lasts less than a second.

You'd be dead most likely!

The point Arbitrageur was making was that continual exposer was bad, very bad. Lunar trips were (are) in a much lower risk range.

whut?

The lunar trips was a propaganda campaign to bankrupt the Soviets.

I think overcoming actually getting a person beyond the Van Allen belts would be the first step to Mars trips.

a reply to: MarsIsRed

I do like everybody else, sustainable, relevant, and consistent on every topic. Science matters, do i believe they were on the moon, yes. Do i believe in the first moonlanding. No,

The amount of x-rays in one day on a trip in space in no way equals to one day in an x-ray machine.Here on earth we are bombarded with all types of ionizing radiation blasts all day ,every day. We survive.

And factually true. Even if the complexity is too difficult for you to understand...

The age old argument is that "it's too difficult for me" therefore some of the brightest minds on the planet couldn't have done it either. Weak argument!

We're also protected by the Earths magnetic field and clouds ect...space is open and poses a substantial risk. So much so that it has several scientists concerned. According to the link, a trip to Mars with current tech would have serious repercussions to the astronauts partaking in the quest.

Thanks Kav, good read. Looks like this is a few years away but appears promising.

a reply to: Jenisiz
Correct, the Earth's magnetic field not only protects us, it offers some level of protection even for the ISS though not as much. The higher the altitude the less protection.

I was just trying to simplify a comparison of exposure levels with something you might be familiar with, but NASA has detailed calculations of increased cancer risk and has determined how many days men and women can safely spend in space under the conditions assumed in their calculations. It turns out the number of days far exceeds what's needed for a trip to the moon but it's not long enough for a trip to Mars with current propulsion tech:

www.cnn.com...

According to a 2010 NASA report on space radiation cancer risk projections [PDF], the average American male who is 35 can safely spend between 140 and 186 days in deep space, assuming heavy shielding, and stay below that 3% increase in cancer risk; a 35-year-old female could spend between 88 and 120 days.

So compare this to an 8 day lunar trip versus a 750 day Martian trip and you can see why one is a problem and the other isn't, I hope.

I highly recommend you read up some Sleeper posts here and his name is Lou Baldin, read all his posts on his site. Also has a Facebook. Mars looks like a trade of sorts, since black ops, kind of corporate military, some major fights going on there. Draconians. Some of what is controlling this planet. And they like humans. I would never sign up for a public mission without coming back. They eat people and am not joking. Very serious about this.

Earth is run as a prison camp by these groups, Moon/Mars/Saturn.
