Neil deGrasse Tyson on Surviving in Space without a Spacesuit

Planning a tour of the solar system? Neil deGrasse Tyson describes what would happen to you if you were to visit the Sun and planets without a spacesuit to protect you from their environments. (Spoiler Alert: He skips Pluto.) Enjoy this video from Business Insider and StarTalk Radio.

The title does not match the video. It says Surviving space without a spacesuit. The video is actual about surviving on other planets in the solar system. These are different questions.

This guy has a sense of humor, actually hilarious

[WillaDaKilla]

An encore with all the moons? :D Please?

[soadspud]

I loved that "old astronomy joke" ! Lol, gotta keep that one in mind.

[OMEGATHENIETZCHIAN]

So Mercury is Crematoria from the Chronicles of Riddick?

For some reason I prefer to "watch" a podcast. I know you guys have told me before you don't want to film the whole thing and upload it to youtube but I would love that. Or even just upload it here with a still image in the background. Basically I'm saying I am too lazy to go to the website in the description and click play :-D

What a perfect, and entertaining, explanation!

That joke @ 0:50 was actually pretty damn funny, NdGT is the man!

Actually according to NASA scientists 30 miles above Venus the conditions are the closest to Earth's as you'll find anywhere in the solar system. As long as you can get a supply of oxygen. 

"The gravity at this altitude is only slightly lower than that of Earth, its atmospheric pressure is similar and the aerospace provides enough protection from solar radiation to make it no more dangerous than taking a trip to Canada."

I'm surprised there was no mention made of the larger moons around the gas giants. What about Titan or Europa?

FIRST COMMENT!! I WANT TO THANK MY MOM, MY DAD, I WANT TO THANK YOUTUBE, GOOGLE, NEIL TYSON, THANKS GUYS

[SuperBuizelll]

Uranus and Neptune are actually rocky planets with massive atmospheres, as I understand. Their solid cores are expected to be not much bigger than Earth. Even Jupiter and Saturn are thought to have liquid hydrogen or densified gas cores. If you could withstand the pressure, you'd eventually land on something; I wonder what it'd be like. Dark, I guess, but possibly not cold due to the pressure.

Sad pluto is sad. Wouldve loved a tiny coverage on it because of that craft that flew by it and made awesome pictures.

So would you actually be able to hold your breath for that long on Mercury or Mars? Wouldn't the near vacuum there just rip out all the oxygen in your lungs pretty much instantly? Or are our lip/mouth muscles strong enough to seal that off?

is startalk available in sydney australia?

[litgnm]

Near the end, I realized in a different way, that gas planets are far away, while non-gas are closer....yet earth is in the middle, and is  inbetween. Solid > Liquid > Gas. I know there's a 'goldilocks' zone, and that it's the area with the right temperature, but how does this apply to gas planets? Are there gas planets which are close to their stars?

I could just google it, but figured i'd post my question here since It's where it originated....

The Hitchhiker's Guide to the Galaxy says that if you hold a lungful of air you can survive in the total vacuum of space for about thirty seconds. However it goes on to say that what with space being the mind-boggling size it is the chances of getting picked up by another ship within those thirty seconds are two to the power of two hundred and sixty-seven thousand seven hundred and nine to one against.

Awesome way to sum up life in the solar system!

He always looks so pleased with himself... Incidentally he's very wrong about a number of these. You wouldn't descend to the center of Saturn and Jupiter and die from the pressure, you'd suffocate and be poisoned long before you were crushed (that's assuming you wouldn't be entering the atmosphere at a speed high enough to be burned alive from the friction.. which you would). He doesn't mention that Venus has a very high atmospheric pressure, so no it wouldn't be like walking around on Earth until you vapourise.. it would be very different - furthermore you'd vapourise so rapidly that you wouldn't get any opportunity to walk around even if you were fit to do so on reaching the surface (you'd already be dead from suffocation and heat).
