they are not saying humans CANT go into deep space, on short missions also.
only you are
All missions into deep space, without exception.
This means short missions can't be done yet, nor can any others.

but it does mean that THEY WILL BE EXPOSED TO IT LESS!!!
x-rays are deadly, there are many documents detailing the dangers of x-rays.. people go to the doctors to get x-rays done everyday..
mostly none.. because they spent NEGLIBLE TIME EXPOSED TO IT!!!!!! ill say it a million times if i have to..
probably several months being constantly exposed to it (of which no human has ever done), and that is to assume that being exposed to GCR's will have any effect whatsoever..

if its too small to measure how do you know they are toast???
you are still trying to say that if someone receives a dose of x-rays over 3 days that is so small that it cannot be measured that guy is toast.

Where did you get "several months" from?
Are you making it up?
Tell me what source said this, please...
NASA has established a three percent increased risk of fatal cancer as an acceptable career limit for its astronauts currently operating in low-Earth orbit. The RAD data showed the Curiosity rover was exposed to an average of 1.8 milliSieverts of GCR per day on its journey to Mars. Only about three percent of the radiation dose was associated with solar particles because of a relatively quiet solar cycle and the shielding provided by the spacecraft.

No, you're trying to put words in my mouth, as usual...
I asked you if they measured GCR during the Apollo missions, first of all...
You can answer the question, or not?
You seem to think they didn't measure it, right?

you are not reading what im writing..
they are NOT saying that humans CANT go into deep space (ie. its 100% impossible), on short missions also.
they are suggesting that it would be best if they didnt STAY there with our current level of technology.
unless you can quote them saying so?? because in your own papers they do say that current technology allows human to survive in deep space for a year using aluminium as thick as ~45g/cm^2.
If something 'allows' for it, this means it is possible using the current technology...
If old technology (Apollo's) has already proved to work, it makes no sense to say that our current technology "allows" for it ...
Here is technology already proven, unique in every way....as a monumental step in human space exploration, nothing compares to it...
Human space exploration, in step-by-step process, which moved us further and further outward, to space....
A 'lack of money', wrong - they spent a fortune on Shuttles for several decades, just to fly endlessly in LEO!

this argument you just made is just so dumb.
we had the concorde ferrying passengers beyond the speed of sound several years back now. ie super sonic passenger flights have been proven.
we dont have the concorde anymore, but the technology for it still exists, ie current technology allows for it..
whats your point again??

you are the one that said if its too small to measure they are toast..
you are the one that said if they cant measure the hazard what would be considered safe..
if its too small to measure especially since the accumulated dosage is too small to measure OVER 3 DAYS what threat is there that forces them to spend so much money on faking it after they have spent so much money on building real genuine working crafts??
p.s. they did measure it, as accumulated dosage although that includes ALL sources not just GCR's and even then it didnt get close to prescribed limits.
originally posted by: choos
in your opinion, how long will it take for an astronaut with or without aluminium shielding to accumulate a lethal dose of GCR's?
originally posted by: turbonium1
You propose GCR radiation over 3 days, in the "accumulated dosage" , would be much too small to measure as a long-term hazard...
"Assume 3 days in deep space averaged 0.4 units of GCR exposure. If it was too small to measure, Apollo is toast. " - Turbonium1 www.abovetopsecret.com...
Let's see...
Apollo measured the GCR radiation, because they were measuring all radiation, and GCR would be included, but it was too small an amount over 3 days to detect, as a long-term hazard.
Do you seriously believe all types of radiation were able to be measured by their crude 'dosimeters'?
How do they measure GCR radiation when they can't even measure any specific radiation, to begin with?
Nobody knows, as I've told you many times...
That is the problem they are dealing with in this paper, in fact.
As noted in the paper, little is known about the effect of GCR radiation on humans, because we haven't gone into deep space yet, where GCR is a real hazard to any humans...
We know aluminum makes it a worse hazard, for humans, but how much worse is not yet known..As I've told you, but you don't understand this point at all, no matter how many times I've explained it to you...

if you think all the technology to live in deep space is available you are wrong.. re-think your position and try again.
thats to ignore all the information and data they have gained from LEO..
and whats this about lack of money being wrong?? you think that going beyond the moon would be cheap??

They had all the money, and spent it all on Shuttles.... so nice try..
And they asked for all the money to 'return' to the moon, and GOT THE MONEY THEY ASKED FOR...and got even more, too..and it failed miserably...
Your 'lack of money' excuse doesn't wash.
Your Concorde analogy doesn't work, either...
We have proven technology for the Concorde, and it doesn't make sense to say current technology 'allows' for it, without pointing out that we ALREADY HAVE TECHNOLOGY WHICH DOES WORK, AND PROVED TO WORK...
A technology is not ignored if it works, if nothing else has replaced it. It simply 'allows' for it, which is NOT THE SAME as being proven to work.
Do you get the basic distinction here?

They had all the money and spent it getting to the moon. Then they got less money and were told it to be spent on the shuttle. Political decisions, not scientific or engineering ones.
Nope they didn't.
Is NASA getting the same level of budget fundng now compared with the '60s? Yes or no?
So far you are focusing your entire argument on radiation, simultaneously claiming that it would have proved lethal whilst at the same time claiming that no-one knows if it would be lethal or not.
Which is it?
If radiation would have killed them, tell us precisely when.
