Will Mars or Venus Kill You First? 

+Longshots Ping is 18.000.000ms though It's 1.800.000 actually my math is bad.

+Longshots probably

Deaken B I've actually calculated it.

i was speaking to long shot.

+Burak Baggins 1.800.000ms actually

+Ryan West I was wondering about that myself, on both those points.

+Ryan West Also, since the core is solid shouldnt that mean that Mars doesnt have earthquakes? If so then thats pretty neat.

+Majestic Mule-Boy Not really. It might lessen the amount, but there's more things that cause Marsquakes. Think of it this way. Planets aren't exactly one piece. And they spin.

+Ryan West I think we still want to see the sky above us (not that many culture like living underground). I was wondering if that possible to force mars to have an atmosphere like the venus one

+Ryan West Actually think there can be liquid water under the surface as well.

+MrTrigun1 Nevermind the "Depending on how much you freak out" line is killing me too. I swear I'm not high

7:26 "Your skin will start to blister. And dissolve. At the same time." Just the way he says that ^^'

It's annoying me when my spacesuit fail and exposes me to the vacuum...

You're dying before you ever got to Mars or Venus. You have to survive the SpaceTime videos first.

There are places in Siberia where it reaches below -85°F (-65°C). Heck, the lowest recorded temperature in my hometown was around -70°F (-57°C). So, comrade, we will survive!

+Canis latrans Sure but ... can someone explain to me how you cool a habitat floating in a layer of air (and by "air" I mean CO₂) at 70 degrees? I mean sure, there are narrow-band thermal emitters and you could always run huge heat pumps that are powered by ... a cheap reliable energy source that can also float. But this really seems like the number one showstopper to me.

+Canis latrans a colony on venus is extermly interesting however it is not as sustainable as on mars because of the lack of soild ground the colony would need all of its resources from earth execpt for water oxygen and other chemicals and you can only build small colonies.

+Penny Lane heat isolated walls and big ass AC units

+Penny Lane Fusion reactor powers big AC that pumps geat out at temperatures above 70C. Not so hard once you figgure out the reactor.

Annubis2 So you're saying lighter-than-air fusion reactors are not so hard once you figure out how to build lighter-than-air fusion reactors? ;) Well, I can't disagree. And yeah, I know the reactor itself doesn't have to be lighter than air but you know what I mean.

+toosas watching a turd on the microwave is better tha cable.

+fjoa123 I only replied to what the presenter said. did you watch the video to the end?

yes i did, and i found it quite interesting. I do think that watching the washingmachine or turds in the microwave is far better than cable. im not being sarcastic.toosas

+toosas and you realize that in 2016?

+Ｍ ｉ ｓ ｔ ｅ ｒ ｕ Ｅ ｋ ｓ ｕ Agreed. Especially considering we don't have to sit through 20 minutes of commercials, trying to sell us more of what we don't need, just to watch an hour long program.

Maybe I'm being old but I'd rather stay at my homy cosy planet Earth. In any case we EVOLVED to inhabit planet Earth and not the other way around!

I understand trust me

Yes that's why God made it for us to dwell on not other planets

Filthy Daemon Spawn Same. The heat and massive atmospheric temps alone would kill in moments. Now time to watch and confirm.

@@stlchucko You should watch. Mars is actually worse

drafer100 I did watch. Venus is worse. A craft that could land on Mars would be melted and crushed before it touched down on Venus.

@@stlchucko who said we have to touch down on venus though

Like, how was this a difficult question

+Tim Stahel (Moustached Viking) It depends on what you are comparing, the radius is about half (3390km vs 6371km) but the mass is a tenth of Earth. But I do agree with you, back in school I remember we got to learn it was just a bit smaller, almost the same size and that is far from true.

+Tim Stahel (Moustached Viking) Watch out! If it gets any smaller, it might be called a dwarf planet! Just don't look up it's size anymore, that way, the measurement doesn't affect the object.

***** If our teachers got that mixed up i seriously want them to repay me for those lost years learning complete bs.

+Tim Stahel (Moustached Viking) The area of a circle is π(r^2), but the volume of a sphere is 4/3π(r^3). So Mars *looks* half the size of Earth, but that works out to around 1/10 the mass (given they have a similar density).

Copydot That's not my point, i'm saying that i was told mars is just a little bit smaller (in size) than earth when i was younger, but now mars is suddenly not even two thirds the size of earth.. I grew up thinking mars was maybe 90% of earth's diameter.

But its worth it.

Venus. Too toxic to name a chocolate bar after it.

I've always liked MILKY WAY.

Y'all ever tried one of 'dem *_galaxy_* bars?

+TheRealBileth yes.

+TheRealBileth you can always exercise like they do on space stations...

+fuzekle yeah, cuz that prevent bone loss :P

sinephase well atleast it helps with muscles ;p

+TheRealBileth Not much since there is a constant force pulling you down. But i think weighted suits would be needed. (Weighting as much as you do) I don't think there would be bone loss like in micro-gravity. No no proof or source though. I'm just making shit up.

+Ilavenya Actually, scientists are cooler than ordinary people:D

David K Yes, we are cooler because we can science the crap out of pop culture, that's true ;)

+Ilavenya They're just mad you haven't given them hoverboards yet. (I don't think they'll get over that anytime soon.)

+Ilavenya I play video games with friends, cosplay when comicon comes to town, have arguments over Star Wars, volunteer at schools, go drinking with friends, and tons of other stuff regular people/nerds do. Of course I'm an undergrad but I still do hands-on research. I've seen grad students huge PC gamers, my mentor is a rocker comic book geek who's also an excellent dancer and was in a family rock band, and I once walked into my friend's chemistry office and there were like 4 post-doc chemists all playing on their laptops together in their tiny cubicles. Scientists are almost always cool, or at least interesting, people. If you find one, ask them any questions, even not related to science. Questions are like their catnip.

Darkrose42 But they ahve moved on from 'all scientists are old white guys in lab coats'. Not much, but some.

Yes.

Love.

cancer probably

Both are the same tbh

​@@medexamtoolsdotcom The prognosis for HIV is fine nowadays, you're just dependent on pills for the rest of your life. So I gotta disagree.

+stiimuli Yup, forgot to add the big wink and \irony after that ;-)

+PBS Space Time LOL, no need for big winks, the underlying irony where both implicitly and explicitly clear... In fact, I'm borrowing that quote and share your video on Facebook....

+PBS Space Time I enjoyed this video, but I was hoping you would continue with your previous series of videos.

+PBS Space Time you didn't forget anything and it would have ruined the joke. thanks for the great episode :)

We evolved to fit our environment, not the other way around.

"take an oxygen tank ... "!!! :-D

Just get a second undergrad degree, if you can afford the money and time. It would be well worth it to go beyond the introductory courses.

+Ouss DZ The Martian!!!!!!

+Ouss DZ Well, It's a movie.

+Wethewax I wanted to point out how the movie was scientifically uncorrect. :)

+Ouss DZ Go on then. Point away. I'm ready to hear your verified facts, keep your opinions to yourself.

iSquared Keep your comment to yourself. I am not forcing my opinion to you to accept it, you can simply ignore it away rather then going me on ...

+Pearl Jii cool. He's the man

+Pearl Jii where?

In other words you have been indoctrinated into the climate religion and how taxes are great.

Graig Simmonette Woah, man. Take a break. It’s not that big of a deal.

Don't lie. Why would lie about that? You're such a liar. Quit lying.

A city on the moon won't end well, just look at moonbase alpha

Marsquakes..

Better bet would be large plastic bins that you could fill with Martian topsoil and rocks. You do get some benefits from this as well. Thick masses of soil, in addition to blocking radiation, also regulate temperature and provide stability and a structure on which to build things. You would have a hard time getting excavation equipment to Mars because of the weight. Big plastic containers could be made in shapes that can be used to build, like Legos or Lincoln Logs. Put balloons inside the structure and you have a ready-made pressure vessel to live in. Venus is still a better option, but Mars at least has some mineral benefits.

I simply hate the fact that the moon and mars have such a weak gravitation. If Venus atmoshpare would be more normal it would be the go to planet lol

Kaiserlicher König Agreed. If only...

+Addison Faber You need to define "Healthier Earth" first. Healthier for what? For plants? If so then more CO2 and a warmer atmosphere please. For archaebacteria? Then a hot reducing atmosphere is healthiest. For humans? then 2-3 deg F warmer with more CO2 in order to grow more plant based food is healthier.

+Addison Faber That's easy, we have a pretty good idea of how to do it. (Assuming you mean 'healthier' as referring to all species including humans.) But such things don't make as much money as doing what we're doing now so we just sit back and pretend Earth is already healthy and all the scientists are lying to us.

+Gareth Dean if we have the tech let the "fat cats" make their money.. When ppl start running out of air.. Or food.. What whatever we run out of first we will do what we have to, to survive :)

+Addison Faber we can, but it would take like 1 000 000 years at least and cost a lot of $. People usually think in terms like 10-20yrs return on their investment.

Addison Faber And what we'll do is screw over the poor and weak to maintain our standard of living. Hell we're doing it now.

lol...

No, we wouldn't be. For the time being, yes. But it's only a matter of time (probably less than 100,00 years, definitely less than a million), when we're not going to be ok on Earth. Shit, global warming isn't going to make us go extinct, but it could wreck our society, and make it so a real disaster takes us out. So could a super volcano going off, or dozens of other things we have no control over. To survive as a species, we need to leave our planet, and eventually our solar system. Unfortunately, we will likely die out when the heat death of the universe comes, but there's no reason to not try to make our species last as long as it can.

It's so funny when people think global climate change won't kill them.

+mergele1000 The idea is to gain knowledge asking questions and having discussions. Its not to get "answers".

On surface? Venus would kill instantly.

+mergele1000 Good call. It doesn't matter to me. Dead is dead regardless of minutes or seconds.

Or maybe you need to be expressly told instead of reasoning the implicit answer... So Mars about 2 minutes. Venus: on surface (assuming you reach it alive) instantly, on a stroll around cloud city without tank the same as Mars, with an air tank on, about 20 min or more if you have sauna training haha, then again the sulphuric acid would be abrasive. But yeah in any case you wouldn't survive very long if you're not wearing protection.

+mergele1000 Mars can violently and slowly kill you no matter where you are. On Venus, it depends - on the surface, you'd die instantly. You'd be pressure cooked into a charcoal foam in seconds. In the clouds, you'd choke (takes about 4-5 minutes to asphyxiate from CO2), and you'd suffer some severe acid burns (that won't kill you....unless you stand out for like an hour). So in all, Mars is the nasty one.

hi, thanks. I am poor and sick. Would you be my friend?

Uroš Peteh lol

okrajoe Shady? Venus is the second brightest thing in the night sky apart from the moon.

@@stevejobs5488 Maybe, but what's it hiding under all those clouds?

And can you imagine if your balloons lose air....

@@stevejobs5488 3rd is the star sirius

+PantsuMann The hot acid makes it hard to get them to last very long though.

Then the cloud city is impossible already. But still, It would probably last longer than on the surface, so I guess it would give them more time to analyse.

+Gareth Dean that is dumb.. we deal in earth with sulphuric acid all the time.. is the chemical most used in all the world. You have close to 100 different materials that deal with acid without problem.. in fact russians sent 2 balloon probes at 53km altitude, their only limited was that the probe who retransmit their signals was a fly-by probe who was following the comet halley.

PantsuMann Hot pressurized CO2 is also not nice. The biggest hurdle with Venus is just building stuff that will survive the air there. Cloud city or underground base it will have a hard time.

I'm pretty sure an average walmart beach ball is made of one of the types of plastic that can be used as a container to store concentrated sulfuric acid because it's impenetrable to the acid, so pump it up with earth air & find a way to get it down to the cloud layer & it should do just fine & bounce around at 50km high for as long as it would stay inflated on the surface of earth - ie a LONG time

+RolandMoone Remarkable isn't it?

Lol

+Gareth Dean truly a work of the almighty creator there is no way the universe, which is random, can produce such a coincidence

RolandMoone Tell that to the idiots on this channel. Sun comes up, sun goes down, you can't explain that.

+RolandMoone And they're in perfect straight line! Spooky, huh?

No.

did you watch the video? It can't retain an atmosphere! Meanwhile, technological developments that would no doubt occur if colonising Venus would likely be useful in fixing the greenhouse gas issue on earth

It's not my understanding that a planet with a solidified core and no resultant magnetic field _can_ hold an atmosphere. We'd need to reliquefy the core and start it rotating. That might also improve the gravity situation. Piece of cake, right?

@@lindax911 How in the hell would a rotating core improve gravity?

Lilac Lizard | It can retain an atmosphere. Just not lighter elements like hydrogen and oxygen. However, CO2 would would stay on Mars’s atmosphere.

Why am I the first like and reply?

@@Lukiepookielemon Ikr? Most of the time this channel is right at the top of the comment section. This time it has almost as little response as I get xD

GameOfEnder i mean, i like the idea of living on venus but its seems way too science fiction to be a reality. And yes i knew titan was a moon of Saturn. Because of Destiny. Lol. Thnx video games

Mak Bones the ESA (European Space Agency) is going to build moon base colonies on the Moon and they will be finished by 2026.

Mak Bones, NASA has developed (at least on paper, not sure how far they've gone in build schematics) a self deploying & inflating blimp, with a return rocket as part of it's package, there's a video on it somewhere, I think the link might be on the previous video from these guys. Basically you go into orbit, then release the package (with astronauts onboard), it goes through the entry phase, then starts deploying, drops a little below 50km as the compressed gasses are inflating the blimp & then the combo of the gasses & pressure floats it back up to 50km again. They do their research/complete their stay & then enter the rocket & leave again, leaving the blimp behind. (the floating thing is just like dropping a cork or space capsule into the ocean - it drops below the surface on impact, but then gets pushed up again by the pressure. The atmosphere on venus below 50km acts like the water on earth & floats stuff So if you want to build a bigger city/habitat, presumably you start with that part & then inflate further plastic bubbles while inside that, or you put on your standard earth chemical factory protective suit & go outside & work on inflating from there. Just need to filter the sulfuric acid out as it inflates & after that you can be inside it with only an o2 tank & then it's just a case of bringing in more air through the top & expelling through the bottom until your habitat becomes mostly nitrogen & oxygen & co2 (being heavier) is purged out the bottom (nitrogen & oxygen are already in the atmosphere at the same levels as on earth, it's just that the atmosphere is SO dense that the result is they are proportionally a far lower percentage of the air. If you can collect (or bring with you) some helium, then that's much better still, since you can float the whole thing up an extra 5km or so & bring your temps down to a Hawaii like temp, but even at 70c, that's quite manageable for short periods. Dry saunas are generally set at between 70c & 110c, with 90c being the norm & those who use them often easily handling 15-30minutes in them at a time & up to about 5 sessions a day - without any heat protective equipment. That nuclear sub that was involved in the Cuban missile crisis & malfunctioned was up over 70c for the entire time it was down there (days)

& as for the moon, same gravity & pressure issues as Mars (but worse), same radiation issues as Mars, is closer to home though, so less radiation on the trip

GameOfEnder _" I don't know where this guy got most his facts from"_ I'd guess NASA, his info is spot on with what is available anywhere you look. The only glaringly obvious thing he missed was that you can go underground on Mars & 1 metre of soil will provide the same protection as 1 metre of other stuff & he also missed that on Venus helium can easily be accessed (and just dumped into the habitat with everything else & it will float to the top out of the way) & used to float the structures 5km higher & so completely negate all heat issues. There's no question Venus is the better option! The gasses are no different to many chemical plants on earth, while the pressure issues on Mars are HUGE & unresolvable

Barek Obema why would we want to map the ocean floor what would be the benefit of that ? Exactly nothing

Bob Cratchit, there is actually stuff on the ocean floor, due to the pressure, right under the floor u can find some diamonds and graphite. Also, oil

Mr Peanut Dab And what would be the point of that?Do you want to exploite the earth even further

woah what the u replied already?

Mr Peanut Dab he's an Internet dweeb

+MrZochal in space you don't have the relatively easy to get materials near by ... or water

It also would be hard to get that stuff on Venus. Plus, mining asteroids in space at least seems easier than dealing with the problems on inhospitable planets.

MrZochal I guess ... I don't have the knowledge to make an accurate statement here.

+MrZochal ive wondered the same things myself. only thing i can come up with is colonies on these planets strictly for the purpse of terraforming

+MrZochal Maybe. Space has two big issues, a lack of gravity which causes bone and muscle wasting and 24 hour high levels of radiation. Materials would have to be got from comets and asteroids and you'd be in constant danger of springing a leak and depressurizing. It might be easier to colonize a comet or asteroid by burrowing into it.

:0

+filthy sanchez no. mars would be constantly bombarded with cosmic rays making it unlivable. and Venus will still have its ultra thick atmosphere making it still unlivable at the surface.

+filthy sanchez points for the pun, if not the science

+Deaken B actually, things would be much different for venus. in mars's orbit, venus would never have had the runaway greenhouse effect. if earth were in venus's current orbit, it too would go a similar route what venus became with being too close to the sun.

filthy sanchez but the greenhouse effect was from all the volcano activity. not it being close to the sun. i mean it may a bit be better because it's farther from the sun but it still would be unlivable.

filthy sanchez Venus is actually in the habitable zone. if the earth was at that distance it would be the right temperature to support rain forests witch is what they originally thought Venus would be like.

+anonymous human maybe you should cut 7 more degrees from that :) www.google.es/?gfe_rd=cr&ei=SWuyVsPNBOas8weVrZXQAg&gws_rd=ssl#safe=off&q=kuwait+record+high+temperature

got the same problem bro

Missed another thing. The thin Martian atmosphere means that you can't land anything heavier than a metric ton on the surface. While there are some options in development to bring that number up, you are faced with the problem of not being able to take much to Mars. You can use multiple launches, but then you have other complications. It's another reason Venus makes a lot more sense.

Mike McKeen, where did you get your limit of one metric maximum mass for any landing on Mars? It appears to me that a larger mass can be safely landed with a sizable enough rocket engine system.

You would need a rocket system in order to land anything heavier on Mars. Such a system adds weight and makes missions more expensive and complex. That's why I mentioned it in contrast with Venus, where no such system would be needed. I got the number from here. www.astrobio.net/mars/mass-launched-raising-the-weight-limit-on-mars-missions/ They do mention another possibility, but its as of yet, undeveloped. Rocket systems work now but add weight.

Excellent!

Ethan Black There is infact oxygen but don't take your space suit off

IM CRYING LOLL

+DallyDragon clearly we should focus future colonization efforts on Planet 9

Spartan0430 we shall start on a planet around Proxima Centauri

DallyDragon Obviously we should focus our efforts on colonizing the sun

Good plan. We're gonna need a lot of sun screen tho, and plenty of cold beers coz the heat makes me thirsty.

and we need to put some sun screen on the fuck rocket

Now that you mention it. Kinda. But with a less shaved beard and sideburns

To me he looks like Scott Manley when you add the beard and full head of hair. xD

+MouseAndShiraz Maybe we can find a way to extract, store and cheaply dump our CO2 excess into the atmosphere of mars...

+FutureChaosTV you're talking about millions and millions of tons of gas. Good luck with that.

+MouseAndShiraz There are tons of rich sources of Tons of things that aren't readily available on Earth. We just don't have the drive to go get it. Go check out the composition of some of our local asteroids. There is more wealth on some of those asteroids than all of America.

I'm not talking about asteroids, though. Every planet we might colonize would not get us any closer to mining asteroids. Asteroid mining is something that can (and probably will) take place without the need for any kind of colonization. It'll just all get shipped back to Earth.

+MouseAndShiraz I think that the Moon will be our first colony outside of Earth.The sheer proximity of it makes it easier to develop.

More area for industry, and agriculture. Also Isolation from natural disasters. The more colonies you have, the more people you have too; bigger population is the natural trend in humans.

I think population is a driving factor. The amount of people on Earth is increasing at a staggering rate and our planet can only support about 9 billion people at maximum agricultural efficiency. The alternative to colonization would be population control, but that topic alone spawns ethical and political concerns.

***** Population control is gonna happen one way or another: whether its natural or manmade.

Ghostowl657 I agree.

To Boldly Go, Where No One Has Gone Before

Seriously liking Mars better, because you can actually get to the surface isn't favoritism

+desarso mom's basement > Mars BIG TIME

desarso, you can use the plastics you create from the sulfuric acid for construction of your habitat & hydroponic gardens & then use the plastic & carbon fibre products (made from the carbon you separate from the oxygen via that hydroponic garden) for most of the stuff you need. If you really need to mine the surface (I would guess some of the volcanic rock would be useful as a hydroponic support medium if you want to grow potatoes etc - that's what they use on earth), then you make a bucket & cord for it from your carbon fibre & drop it over the edge. Let it drag along the surface for a few metres & then pull it back up

Robots!

Dmytry B I think about 3538

i think at the end of this century

Dmytry B 80 tons of pressure will instantly crush you while being cremated. Cool idea but, the Venusian surface is not a good idea.

we have no choice, earth will be totally polluted in 100 years, nearest planet is venus, our twin planet, yea its awful conditions, but if mankind want to survive we must colonized it.

+Martin Willett Even scientists have dreams.

Gareth Dean Dreams are reasonable, the concept of destiny is not.

Martin Willett I dunno, it'd depend what you meant by it. As some magical guiding force that leads to a predetermined outcome I think it'd be pretty stupid, but people are often less concrete than that, I find you can usually replace it with 'potential' and get the same meaning. But then I'm not the video maker, maybe they have some sort of New Age belief about it all, it's certainly not uncommon in that sort of crowd. (See also Roko's Basilisk.)

Gareth Dean Far too many scientific (or rather otherwise scientific) people think that man has a destiny in the stars, that we are the sperm of Gaia or some such teleological fantasy. This idea needs mocking. We are animals. We exist because our ancestors bred. That's it. The past causes the present. The future does not suck. If anyone talks about a destiny in the stars grab hold of your wallet and wish them luck with their quest. It does not benefit you if someone else has descendants living on Mimas. Don't fall for the idea that you benefit from other people going into space, at least not to the point that you need to pay them to go!

+Martin Willett It's called being proud of your fellow human species, you degenerate.
