  • Re sulfuric acid:: The acid is a complete non-issue. Sulfuric acid is one of the most common industrial chemicals - there are many corrosion resistant materials that would mitigate the threat of sulfuric acid material degredation, even in a high temperature environment. PLUS, the acid is suspended way up in the cloud deck - probably only trace amounts at surface. There is no rain at the surface, only an acid mist way up in the clouds.

  • Answering responses: Pressure @ bottom of ocean = 1,000 atmospheres, 10 times venus pressure. So a vessel can easily be built to withstand venus pressure. Space suit? = not likely. Heat can be managed with a heat exchanger - the only limitation is energy. You would need a nuclear powered heat exchanger to stay cool (so your exhaust heat would be much greater than 900 degrees F). Interesting Venus fact: Around 30 miles up temp is 70 deg & pressure is 1 atm. Floating colony? New Bespin?

  • It's not the gravity on Venus that stops us from ACTUALLY landing on Vanus it's the thick atmosphere of acid clouds that stops us. This is a fake and a movie but it has great graphics and shows what it PROBABLY looks like on venus. Someday we actually will be able to land on Venus but right now temperatures are just to great on venus and there are no suits that can save us from that.

  • The problem is that the report is 260 page long.

  • Maybe you can attack me with the moon landing hoax theory but NASA actually planned a manned Venus Flyby in 1974 which would have used the technology used in Apollo moon exploration program. You can do the research on the wikipedia. There is even a link with the actual research report on that project.

  • man will never make it that far , there not smart enough

  • @619badazz13 it's not that we aint smart it's the fact we still yet to find out the best way of getting there

  • @MadStylezuk the way i look at it ,if man cant even make it to the moon what makes them think they can go to venus

  • this is wak!!!!!!!!!!!!!!!!!!!!!!!!

  • @GogetaSSJ2001 just like your prom night

  • This is completely far fetched, it isnt only the surface pressure we'd have to contend with, but the blistering heat, sulphuric acid atmosphere and , well....whats the point in wasting the money to send people there anyway?!!!

  • @rickequinox

    Although I agree this part of the show really is far fetched, it's also one of the best. It helps people realize how incredibly hostile the environment on Venus is.

    It's interesting to note that the lowest layer of Venusian atmosphere is in fact CO2 in a supercritical liquid state. It's an ocean of super-hot liquid carbon dioxide. Nasty stuff.

  • I've never quite gotten exactly why all probes to Venus' atmosphere get crushed/go out of commission so fast. I'd expect them to eventually be destroyed by the acids, but in the timespan of a week or more, not in minutes. (If we can compress air into a VERY small space, why can't we equalize the pressures inside and outside the probes?)

  • @shmuli9 it's not the pressure that was the problem it was the temprature. the insides of the camera's melted within an hour or two. (though i feel confident if we tried again we coould do better with newer composites)

  • @NickBlackDIN I keep forgetting that even though it was less than 50 years ago, human science was "primitive" at that time and things did melt - go awry. (I don't even think they had KEVLAR back then.)

  • So, he kicked the robot? WHY!?!?!

    Remind me never to destroy historical artifacts

  • More CO2 propaganda from europe.

  • @Minionuup LOL where show me

  • @Minionuup

    Don't confuse man-made climate change with the greenhouse effect. The greenhouse effect is a well documented occurrence with loads of scientific data to back it up. Venus is the way it is in part because the atmosphere is 96% CO2. That's a fact. If you want to argue man-made global warming that's a different beast altogether.

  • God this is so suspensful.

  • Some say if humans don't stop doing what we are doing to our planet, Earth will one day be just like Venus. A hellish oven that can support NO life ever.

  • @WarriorLeonardo That's alarmism. We have to stop polluting because it destroys habitats and limits natural resources, but global warming is a big fat lie. Just compare - Venus has 95% carbon dioxide in the atmosphere. Earth has 0.03% carbon dioxide in the atmosphere.

  • is this real footage?

  • @lamonita798 no we only made it to the moon

  • Cool !

  • And venus is closer than mars. Its doable engineering wise.

  • landing humans on venus makes about as much sense as landing humans on the sun.

  • i love this show, the best 2 part ever :)

  • Even if we could develop heat and pressure withstanding lander and spacesuit, to get off Venus we will need to build a rocket many times bigger than the ones that take us from earth just to overcome the air drag.

    Venus has roughly about the same gravity as earth but 92 times the atmospheric pressure making air drag a huge issue.

    Man may one day set foot on Mars and even Titan... but we will never land humans on Venus.

    Robotic rovers and UAV's are possible though.

  • Venus sounds just like Penis.

  • this is fake... no one has ever landed on venus

  • duhh anyone who thinks we have alredy is a bit retarded dont you think?

  • You don't scuba dive without a buddy, you shouldn't do a planet EVA without a buddy.

  • isn't real programm

  • Like, absolutely stunning. Unfortunately, this video is hosed because it's a 16:9 widescreen image horizontally squeezed into a standard 4:3 frame, with inherent distortion. Way to go, babes!

  • i did some googling and this is the info w.r.t pressure

    atmosphere in earth at sea level = 14.7 psi

    atmosphere in venus = 90 times that of earth = 1323 psi

    we can feel 1323 psi at approx 3070 feet in ocean, since 1 feet of water = 0.44 psi and every 1000 feet the pressure reduces by 3%

    JIM suit deepest dive by human=1400 feet. so our current tech can handle only half of venus pressure . but hey if we can travel 4 months land humans in venus, lets assume suit can also be built :)

  • I don't know what could be more impossible the astronaut walking the surface of Venus or the easy take off the craft had from the planet.  =S

  • Is this a Joke?

  • Comment removed

  • It cannot get any faker than that video. Venus is hell, nearly 1000 degree temperatures, acid rain, and 95 times the atmosphere pressure than that on Earth would've crushed that astronaut like a bug before he even landed.

    There is no way anyone or anything could survive on Venus.

  • Do you realize that people have gone to the bottom of the ocean where the preassure is 1000 times that on venus?

  • No. The Marianas trench has a pressure of 1,000 times that at Earth sea level. That's only 10 times that of Venus. And though people went down there, it was in a hugely armoured bathyscape. They didn't walk about on the bottom in diving suits because they would have been crushed by the pressure immediately. Going to Venus would be cool, but you wouldn't be able to walk about like this unless you are capable of carrying about 15,000lbs on your back!!

  • hmmm, NO .. you have FAIL

  • @otenyuda but they did it without leaving the batyscaphe, and it wasn't nearly that hot. It's more the heat than the pressure that is the problem. Venus is a Hell of a planet.

  • @otenyuda true but it isn't concentrated sulfuric acid nor is it 250'C

  • no its give or take 400 degrees c!

  • @otenyuda

    Actually, AFAIK, the pressure is about the same.

  • @otenyuda wtf for a comparison is that.... I dont think the bottom of ocean is as far as venus....

  • LOL

    Dude is is obviously fake, cos it is from a TV series called Space Oddysey: Voyage To The Planets. Idiot please read before posting

    Just read the description

  • 100% right

  • The Venera 14 lander survived only 57 minutes (the planned design life was 32 minutes) in an environment with a temperature of 465 °C and a pressure of 94 Earth atmospheres (9.5 MPa). The lander probably still rests on the surface of Venus today.

  • when you think about it. even if the lander vapourizes its always going to be there. atmosphere anywere

  • that's true. but Russia,(formally USSR) are planing to sent another probe call Venera-D,which expected to be launch sometime in 2016, will serve as the flagship for a new generation of Russian-built Venus probes, culminating with a lander capable of withstanding the harsh Venusian environment for more than the 1½ hours logged by the Soviet-era probes.

  • WHY / HOW is Venus hotter than Mercury?

  • Venus is covered with an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light. Venus has the densest atmosphere of all the terrestrial planets, consisting mostly of carbon dioxide, as it has no carbon cycle to lock carbon back into rocks and surface features, nor organic life to absorb it in biomass.

  • venus has a dense athmosphere mainly composed of greenhouse gasses. unlike mercury venus holds onto the heat it gains.

  • Its atmosphere traps the hot air within Venus.

  • traps the hot air? I think the atmosphere *is* the hot air...

  • Another possibility might be to use Helium filled balloons to get off the ground. Once the lander is at a suitable height the astronauts can drop the balloons and start the rockets. What do you think?

  • An robotic mission to the surface isn't very hard, a mid-size expendable launch vehicle would suffice.

    A manned mission to Venus would extremely difficult. A series of Saturn V-like rockets may be necessary. Aside from the Venus Suit, the planet has an orbital velocity of about 7 km/s, thus requiring a much larger rocket than depicted.

    Balloons might will work to get past the denser part of the atmosphere, and then fire the rockets, but maybe not. There's only one way to find out for sure.

  • Someone mentioned above that you need a rocket as big as a Saturn V to get into Venusian orbit starting from the surface of Venus. But is it really that hard? Despite the almost Earth-like gravitation the atmospheric pressure there is high enough to "climb the atmosphere in small steps". In the video dust sinks to the ground; It doesn't fall. Fire a small rocket underneath the lander and you climb a little higher without(!) instantly falling to the ground. Then fire another rocket and so on... .

  • but you forgot one inportant factor, which is why is venus so horrible in the first place. don't forget that venus is much closer to the sun than, earth, its has a very long duration of rotation which may be evry difficult for earth life to adapt to, the slow rotation causes the lack of a magnetic field, which protects the planet and its atmosphere from harmful radiation and from solar flares, the tilt of the planet's rotation is also very small which leads to lack of seasonality.

  • can an astronaut be able to withstand the high atmospheric pressure and extreme heat on the Venusian surface? highly unlikely......

  • beware off the ghosts

  • venus is like earths evil sister

  • If NASA is right, how come the parachute of our (USSR) lander didn't burn up and the craft destroyed? At 900 degrees, you would expect that. What are we not being told???

  • A VENUS ROVER!!!!!!!!!

  • Make it rain on Venus and have solved the problem of pressure on Venus!

  • It does rain on venus, it rains acid

  • its not that easy to terraform Venus, very difficult actually.

  • I know it is hard but If you never try to build it, you will never know how to build it. Fortunately all we have to do for Venus is just regulate its heat input from sun and the rest is automatic. As soon as you have blocked 30% of its total heat input the planet will start to cool down within months and the rain fall into ocean will actually start on the surface of the Venus. You have just started an automatic chain reaction to make this hostile planet into a habitable earth like planet.

  • As the rain fall, the atmospheric pressure of the Venus will start to come down and the most important thing will happen which is, one of the worst green house gases is the water steam will reduce. As the steam decrease so will the green house gas effect and the planet will cool down even faster and faster until it reaches an equilibrium where atmosphere is earth like. Of course Venus will not have the oxygen to breath for humans and for animals but the plants will thrive and they make oxygen.

  • Scientists and technical people can then live on Venus without pressurized suites inside enclosures and walk around Venus surface with oxygen tanks on the back I suppose. To terraform Venus into exactly earth like will surely require some time. As a general rule, you will need to grow as many trees and vegetation as are on the planet earth to have converted enough CO2 into O2 to live on Venus without oxygen tank. This might require 50~100 years time period or more.

  • my god, no one has given me such a long reply, i congragulate you lots! :) and i agree with on your terms how to terraform Venus. and i hope humans one day will be able to.

  • Sure there will be few technical difficulties to challenge our determination but put it this way, it will be our first baby step towards cosmos and all the wonders of it.

    If you want to live there in near future you better get stated now.

  • ok... you seem determined to visit Venus any day soon..., i'm a Venus fan too, :) but you have to realise that with the current limited technology, Venus is one hell of a challenge. In my opnion, we should start step by step, and humans will definetely consider Mars first over Venus, cuz Mars is much safer, doesn't mean its alot easier though. i like the concept of terraforming, a lot, but we should take care of Earth first, cuz Earth is much rarer than Venus-like and Mars-like planets.

  • You are right, mars is the way to go. What was I thinking.

    :))

  • you're welcome :)

  • is is true?

  • No its not, its a fiction film

  • you don't get you much do you? lol...

  • they could... maybe not tomorrow but in twenty or thirty years. the pressure is only fifty times higher than the one of the earth and that's the same like 5000m below the surface of the sea. and we already were there.

  • yes, but they don't swim at those depths..

  • Speaking of metals that could survive high temperatures, Tungsten has a melting point of 6192 degrees Fahrenheit. Titanium is 3000 F, and Palladium is 2830 F. There are quite a few materials that can withstand Venus' heat. Even the Space Shuttle's tiles can withstand temps around 3000 F.

  • They did a god job depicting how smoke would really behave in that dense atmosphere on 1:58.

  • I think you could terraform venus. Place huge sun sheild in path of the sun and vent pressure by deploying robots to expell gas from the atmosphere towards the sun. If there was no C02 venus would have a mean temperature of 30 degrees C

  • There's a problem with the sunshade idea. First it is too massive and requiring too many resources and capital, not to mention time to build. Second, the solar wind pressure on this shade would cause it to fail. Third, Venus is so massive and so hot, and the atmosphere so thick, that it would take a long time for it to cool down. I like the comet-bombardment idea better. Blow some of its atmosphere off by an impact. Or we could just live underground.

  • oh..your very smart man...go work to nasa.

  • True, dude, that launch unit is too small to escape the gravity of Venus. You would have to have something similar to the Space Shuttle rockets.

  • Mmm The guy said "The gravity is killing him" because it is 0.9 of earth that is, almost like the one of earth and he is wearing that heavy suit. But I guess they give a "pase pernocta" to reality because with that gravity you can not launch a capsule to orbit like if it was in the moon. Here on earth with a gravity just slightly higher you need a huge booster to do just that. But the overall simulation is really great.

  • Venus here looks kinda like a browner version of Mordor.

    Freaking scary. I'd never want to land there even if I could survive there for years without melting.

  • I would love to be the first Zillionaire To atttempt to terraform venus but from the look of things i don't think Venus is having it. That planet seems alive. Also I am in agreement with the two gentlemen below about

    the war in Iraq and Africa

  • Fuck, Venera should be already melted.

  • The Venera landers were composed of Titanium, which has a melting point of 1668 degrees °Centigrade.

    The temperature of the surface of Venus is about 480 °C; Not even close to it's melting point.

    The Venera landers are not flat puddles of liquid metal, they are all still standing. However it's insides, which were not of Titanium, has already melted.

  • I don't think landing a craft on Venus would be half as difficult as getting it back into orbit. The gravity is about the same as Earth's never mind the atmospheric resistance!

  • although you could imagine using a balloon to tow the spacecraft into the upper layers of the atmosphere and launch from there.

  • This an awesome recreation, extremely well done but don't think its going to happen for quite a long time. Can't imagine any human lasting on the surface long enough to rationalize the expense and risk involved.

  • Venus is over 900 degrees F on the surface. Pressure is 90 times our sea level. Carbon-dioxide atmosphere, and sulfuric acid clouds. We saw Venera was composed of titanium, a Venus-suit might be constructed soon which could resist corrosion, temperature, and pressure. Still wouldn't want to be out on the surface long though.

  • For those of us that enjoy astronomy &/or science fiction, such a show acts to stimulate the mind on the question of "WHAT IF". This was a great show for just that purpose. Of course we are no where CLOSE to pulling off such a mission technologically but it's an entirely new way to think about the "what if we could" & "what would it be like" questions.

    Insulting our intelligence? Quite the opposite: it stimulates & entertains. (by the way you spelled "intelligence" wrong there Einstein).

  • I understand that this isn't real ... but seriously. Anyone who would step on that planet would be incinerated instantly.

  • Hang on!!!... Didn't they say at the beginning of this, that the atmospheric pressure on the surface of Venus, could crush a submarine?? So how can a guy in a space suit walk around without getting instantly squished???

  • For technology to allow this entire "theoretical" trip through the solar system, it certainly would be such to also necessitate the creation of the astronaut suits & landing craft to withstand such pressures & temperatures. Duh.

    Need to use the imagination for ALL aspects of a program such as this. It would be like asking "hey how can Superman breath in space?" or "how did Wile E. Coyote survive that 1000 meter fall from that cliff & survive?" C'mon--need such questions even be asked? lol!!

  • im bot an expert, but isnt the atmospher on venus like, over 400 degrees?

  • A mission to the surface would be possible if you didn't mind never coming back at Mars landing prices. To come back it would need a rocket as big as it takes to get off of earth to land and much heavier and insulated to resist the heat and pressure. It would be huge and cost hundreds of billions at least.

  • One option to get off the surface of Venus is using a blimp like vehicle. This vehicle could take you to the upper atmosphere and you could fire the rockets from there.

  • I think the point here is "Would you like to live on a Venus-like Earth?"

  • 'no need to put man on venus its suicide'

    Yeah, its brave!

    'probably cheeper to put man on mars'

    Now you are getting it. Cost. Plus mars is a better camping spot anyway.

  • Send condemned criminals to Venus for exploration in lieu of/ for execution.

  • that would be too expensive u dong

  • That can be debated "u dong": Death row inmates spend HOW MANY years alive until they are actually executed? How many death sentence auto-appeals are filed despite objections from the inmates themselves? How many tax dollars are wasted feeding/housing them until then?

    Two words: "Charles Ng": 1 death penalty case = 14 million US tax dollars. Never mind that he was arrested in 1985 & FINALLY sentenced in 1998 (blame Canada for half of those years).

    So hell, why not send them all to Venus!

  • Everything in this show is possible and the science about the planets is 100% correct. If you care to check, the main constraint on space exploration is cost, not technology availability. Its was noted, as early as the 60s, that massive spacecraft and stations were already possible except it would be too expensive to build them.

  • Actually, Venus would not melt most metals used in space vehicles. The metal would survive, its the machinery inside it that would have problems. A possible solution would be to pump the rocket fuel around as coolant, or even employ actual refrigeration.

  • your right, its impossible to ever develop a lander that could withstand that heat today or any time in the future ever ever ever ever ever! Impossible, why would anyone want to land on venus, cant grow no corn in no venus dirt. Try real science maybe? heh, idiots.

  • the suit he wears on the surface is less believable - it would need massive cooling, even the faceplate would need to be cooled or it would get hot enough to cook the astronaut's face.

  • Uh..actually the USSR sent a number of probes & landers to Venus that withstood the heat & pressure long enough to take various measurements & even a few pictures. What, you've never heard of "VENERA"?

    Without their numerous Venera probes & landers (they were numbered up to "Venera 16") that descended to Venus-most of which failed before reaching the surface but relayed at least SOME data before expiring-we may not even know today such critical information as surface temperatures & pressures.

  • Yeah, it's sooooo much more fake than Star Trek or Star Wars.

    Add kennyboygm to the "World Imbecile Count".

  • You're like the 12-year old who just discovered he's smarter than the other kids and is just dying for everyone to notice, aren't you? You may or may not be a brilliant intellect, pal, but you're quite silly.

  • Thats what they said about submarines when Jules Verne wrote a novel set on one.

  • What are you saying then,that todays' submarines can withstand the water pressure in the deepest depths of the oceans? Not even dude! That pressure is the same as on the surface of Venus! The sub would be destroyed quickly! It's happened before. Naval accidents have occured of this type with many lives lost! Get real dude and do your homework. This is reality!

  • The submarine is not a valid comparison. Most subs are not DESIGNED for deep dives, certainly not the big naval ones because it is not strategically important. The pressure at Venus' surface is more like 2 kilometres underwater (ie: Atlantic plain), not the greatest depths known, and this depth is reachable by using exploratory subs and robots employing exotic materials. Materials that would be used for a manned Venus landing of course.

  • Now lets look at how mere fiction can make startlingly accurate predictions:

    Captain Nemo's Nautilus was double-hulled, purified seawater into drinking water and ran on electricity - all used in modern subs.

    Bingo. Even if depictions of a technology are fiction, that does not mean they will be possible oneday.

  • On the subject of subs, lets look at a good example of how personal incredulity such as yours can reject a valid concept, just because it seems unfeasible at the time:

    John Fulton invented the first submarine in 1805, with a dive of just 8m. Further funding for its development was rejected by both the French and English governments because they were not impressed by demonstrations of it sinking much larger surface boats using towed charges.

    But look at what is possible now...

  • I'm not sure why this issue annoys you so. If you cannot imagine how to land a manned craft on Venus, then learn how it could be done. Do your homework, as you said to me. Science is about achieving the impossible, after all.

  • It doesn't annoy me. It's Hollywood!

  • I don't understand. Are you saying Hollywood fiction annoys you period or is it the presentation of what you think will always be fiction as 'drama documentary'?

  • I'm all for space exploration,the possibilies,the future.., in fact Venus fascinates me more than any other planet because of the extremes that exist there. I just like knowing that what I'm looking at,listening to or hearing is true based on facts from evidence we have aquired through science. When the movie machine interferes it's all about doctoring up with beautiful pilots on wonderous ships that have nothing to do with fact!

  • 'Venus fascinates me more than any other planet because of the extremes that exist there'

    Aye. check out Titan as well, if you like the very antithesis of the extreme that is Venus.

    If you doubt that this film is not well researched for realism, please check the 'space doctor' game on the channel 4 website. Very educational and very fun. On that note, I'm gonna play it now:D

  • re: "Venera"-we HAVE landed on the surface of Venus & w/technological evolution to the point that this journey would be possible, it's VERY feasible to think that science can evolve to this point. Notice they couldn't stay on the surface for very long. So w/all that is spewed out of Hollywood, you have to attack THIS show? This isnt even American-it's British (BBC). As popular as Star Wars & Star Trek are & people gripe about THIS show? Wow, far many more imbeciles in this world than I realized.

  • I'll tell you what DOES annoy me about space exploration, if anything. NASA blows untold millions a year doing it and the public, some of them at least, rave over it. That money could be spent on the problems that affect THIS planet, such as global warming, population growth and conservation. And it would be, if only the voting public thought those things were cool.

  • NASA's yearly budget is around 16billion dollars, the Iraq war's yearly budget is averaging at around 60-70billion. I would say developing new technologies to learn more about the universe is more important than a war for oil.

  • Well quite. We could probably give full vaccinations to everyone under 10 in Africa for the next 50 years with that money as well.

  • YEAH, CANT WAIT UNTIL BUSH IS OUT.

  • for ur info, oil generates machines made by technology

  • @Vol7ar we need oil to fuel our cars.

  • @Stephen19852009 oil can be obtained from many other sources. It is no excuse.

  • @bessadale the only other source oil comes from is whales.

  • @Vol7ar

    Where’s all of the oil? Maybe we should just let murderous tyrants violate all of the UN sanctions they want because we don't want war now do we? You wouldn't be watching these informative videos on youtube if it wasn't for war. You wouldn't have this country if it wasn't for war. War isn't pretty, but there is no peace that isn't post war.

  • Its a docu-drama on channel 4. Fake but based on pretty real science.

  • Part 2 manages to be even more exciting than Part 1.

    While there are aspects of the entire Venus mission

    that belie credulity, it's a wonderfully well done

    production with excellent special effects. Well worth watching.
