What Is Radiation Shielding?

Kerry Lee, NASA Orion radiation system manager, explains how radiation shielding is used to block harmful particles coming into the spacecraft without producing secondary particles that can cause even more damage.

Wish nasa made more videos like this still. I think it would be really cool if NASA did short documentary style videos on topics like this. Just a lil more details and some examples with in-depth explanations would be great.

There is an error at 0:10 where the video restarts. This is causing the subtitles to desync with the audio.

Thank you. It's so very very very annoying.

[@hapkidoglock]

So what shielding did they use in the 60's when we went to the moon?

[@RallenBosessen]

+hapkidoglock probably none. Moon is kind of protected by the magnetic field of Earth. But when you go outside the Earth system, then's it's another story as you're exposed to direct radiation from Sun

how you block all cosmic-ray , gamma-ray , x-ray and many high energy particle with only 0.1 mm aluminum fiber shield use in 60s' apollo space suit for 8 day mission in space ??? 😅

[@eventcone]

You don't. But the flux of each of these is low enough not to result in a remotely dangerous dose during the course of the short Apollo missions (less than 2 weeks).

Great explanation. That makes perfect sense.

[@myusername3689]

Useful for when the magnetic pole shift comes and we have to shield a lot more than just spacecraft.

Is the radiation slipping through the windows?
Windows are structural weaknesses.
Maybe we should rethink how we look out at space?

[@innerspace56]

Hey kids! Just to be clear, as you travel through the deadly vacuum of space, your spacecraft, your body, and your brain are being constantly penetrated 24/7 from every direction by unfathomably powerful particles. Be sure to apply for those fantasy Mars missions asap, but remember- you can only go once..

[@johnpaulbenedict7558]

Cool!

[@waynusp1664]

Soooooo, how did they get to the moon many decades ago without any shielding?....just a thought!

[@darkdragonsoul99]

by most of them dying of cancer a decade later.

[@itsmetrumpt7330]

They didn't, one of the biggest lie ever told.

[@MsRebeccaLovely]

They didn’t go to the moon

[@Hiihtopipa]

@@itsmetrumpt7330 lol they didn't know about outer space being radiated until the people who went there made raports saying it is. In their eyes were blind spots where the high energy radiation hit, and as someone said they died of cancer. Going forward takes sacrifices.

[@liammurphy2725]

@@Hiihtopipa The Van Allen radiation belts were discovered in 1958. No people were harmed during the making of this discovery.

What about gold? Gold has a lot of protons and neutrons and yet NASA uses a lot of it as protection from heat and radiation

[@rocketyak4014]

From what I've seen it appears gold is used as protection for infrared and visible light radiation. However the radiation they're worried about is of a much higher energy level, making gold unsuited for protection.
