NASA’s Orion Engineer Admits They Can’t Get Past Van Allen Radiation Belts

Pine this shizz!

This is gold!
PIN!

Bumpety

There are safe zones and you fly through the very fast this ensuring minimum exposure. case closed.

So why aren't they doing just that? Instead they have to send an unmanned test craft up there first.

Care to link us to bloody anything backing that bullshit up? No I thought not because you pulled the entire load of stinky chit out of your backside.

The belts completely surround the planet genius, if there were "safe zones" the cosmic radiation would come through and fry us all.

As with all radiation it is quantified via intensity & length of exposure.

Lol...nice shot bro. He couldn't even return fire!!!

Buzz would've died a long time ago.

good thing the van allen belt didn't exist 50 years ago or us Americans would never have gotten to the moon!

Think of them as 'zones' and you'll be fine, they are NOT uniform "belts" as referred to and it IS possible to navigate through their least intense areas safely.

The Apollo astronauts wore dosimeters and results showed that the "dose" they got to and from the moon was LESS than the 5 REM doses that atomic energy workers receive on a yearly basis.

Sorry to buzz kill, but the reality is different than you posit.

Perhaps.....in the 1960's - transistors, Which were state of the art at the time, can withstand this radiation. Whereas now, computer microchips and such cannot.

I remember reading somewhere years ago that Russian MIGS had transistor technology in them because this technology is not vulnerable to EMP radiation, and modern computers are. I don't know if this was true, or is still true or not.

Just a thought...

I mentioned this to my friend and he says that each ship is different so they are testing this orien ship. Apollo was tested ok

Please stop posting this stupid shit.

Read this. Educate yourself.

I did try to tell them this, but you said it better.

We already have at least two threads about this.




Orion is supposed to be more versatile, as in fly more often, even when the alignment is not so good.
If it goes deeper into the Belts it can do that.


The Apollo Service Module was tested unmanned on the Apollo 4 flight.
But of course it didn't travel this deep into the Belts.

The Orion hasn't finished development yet, funding is low and progress is slow.
The next test flight (around the Moon) will also be unmanned and is scheduled for 2018.




Pray tell, why are they called belts, and what is aurora

The reality is we are trapped on this rock ...

They know this and have decided to spend their money on a different type of transportation ... CERN !!

Unfortunately I don't think the "Creator" takes to well to us messing with such things ...

2 cents!!

Silly monkey hybrids, you aren't going anywhere.
The others don't want you stinking up the place.
You have a perfect planet here, well, you had one..

Nope. Wrong. Fail. The trajectory taken by Apollo avoided the most intense parts of the Van Allen belts.

Using SPENVIS, here is the dose expected for an Apollo astronaut sitting inside an Apollo spacecraft with about 7-8 g/cm^2 areal density on the trajectory taken by Apollo to the moon:

That dose isn't dangerous at all.

With that said, you cannot send astronauts on an Apollo command module through the same region on the same trajectory as Orion EFT-1 without risking the astronauts developing mild symptoms of radiation poisoning.

Here is the expected dose if you were to send Apollo astronauts in an Apollo command module on the same trajectory as Orion EFT-1's final orbit:

Nearly 30 rads of radiation. At that dose you are approaching the threshold at which you may start to exhibit mild symptoms of radiation poisoning according to the CDC:

"Mild symptoms may be observed with doses as low as 0.3 Gy or 30 rads."

Still won't kill you, but it might just make you sick if you fly Orion EFT-1's trajectory with the older Apollo capsule. The electronics on that capsule were less susceptible to radiation though. Computers were also in charge of a lot less of the Apollo spacecraft, and were built using core memory that generally could not experience a "bit flip" due to radiation the way modern memory chips do.

You're FOS.

Show your work.

help from the demonic greys

I performed the calculations using SPENVIS. You're free to check my work.

WHY IS THIS VERY IMPORTANT INFORMATION NOT PINNED????


..

The premise of the post is flawed, that's why. And you can see that when Astro uses facts and science how it gets ignored. Fools will be fools, after all, and that simply isn't worth pinning.
