The engineering needed to cope with the Venus environment is sooooo different to what is needed for Mars
I know it's crazy! But if successful then we could colonize any terrestrial world or moon in this system.
"engineering for Venus environment is sooooo different for Mars"
???
Not to be unkind, but this seems like a quite stupid remark (as in: WELL, DUH!!!), considering one is plus 464 degrees Celsius (°C), and the other minus 60 degrees Celsius (°C), go figure.
@regger099 Why do you need to be so mean?
I strongly believe US will be able to pull off much more than said here.. cuz there are cold spots (~+25c) at venus .. now if that spot/region keeps changing position with day night then rover may have to chase that but even if there is tiny region which happens to remain between day and night that will be rovers spot.
Also for our moon and Saturn’s moon titan
Good video, virtually no padding and great points. My only nit is that Mars is more structurally similar (axial tilt, seasons, evidence of water and erosion) where Venus is only comparable in size, as a day longer than its year and rotates very slowly clockwise. But as you said at the end of the video, it's really our own local exoplanet. Nice work.
Day length on Mars is also remarkably similar to that of Earth, just a bit over twenty-four hours.
It’s not just more similar in size, though. The surface of Venus is hellish, but the closest analog to Earth is on Venus roughly 60km above the surface. There, the atmospheric pressure is about the same as at sea level on Earth. It’s still hot, around 40°C (104°F), and not breathable since it’s nearly completely CO2 and a little H2SO4 but much more Earth-like than anything on Mars, which is CO2 and a little N2. Also, thanks to the thick atmosphere the radiation level is comparable to Earth’s. And Venus’ gravity is ~90% of Earth’s.
Contrast this to Mars with only 1/3 the gravity of Earth’s with very high levels of radiation since it doesn’t have a magnetosphere and the atmosphere is less than 1% of Earth’s. And Mars’ temperature ranges between 20°C (70°F) and -153°C (-225°F). The length of the day is similar but not the same and would be noticeably different to astronauts over time. And while the axial tilt is similar now the lack of a large moon like we have means Mars’ tilt can vary wildly. So while Venus is Earth’s evil twin it’s still our twin, which Mars is not. 😛
Anyway, it’s just a pet peeve of mine because certain people, especially those who advocate Martian colonization, keep overselling Mars’ similarities with Earth and completely ignore all of the ways it’s dissimilar and so hostile to humans. And while high above the surface of Venus would be way better than anywhere on Mars for people I don’t advocate doing that since the cost and technological challenges are too great. Due to lower technological challenges I expect astronauts will visit Mars around the middle of this century but due to its harsh environment I don’t think there will be any colonization for centuries or millennia.
I want floating cities on Venus instead of underground bunkers on Mars!
well if thats what you want, all you gotta do is tell NASA and they'll hear you out
I'm team Europa. At least there's water there. Still an ice bunker but you won't fall into an 800F acid bath.
@@CORYJOHNM wonder how 1.3g would effect the body
@@caesarsalad1170 that don't sound too bad. Like wearing a backpack 24/7. Probably less negative effect that less gravity. Microgravity has shown to have permanent effects on the astronauts. 1.3 gravity would blow out knees and joints over time. A hyro suit would fix that if you don't mind a juicy suit.
@@caesarsalad1170 Wrong, Europa has 0.13g. Which is even less than Mars. Venus would have a similar gravity to Earth.
The current leading models suggest that Venus not only used to be much more Earth like but also hosted substantial surface water and seas. Not only that but it did so for over 2 billion years before runaway volcanic eruptions not only induced a runaway greenhouse effect in its atmosphere but also increased the thickness of its crust and resurfacing the entire planet. What I find most intriguing about this hypothesis is it would mean Venus not only possessed the conditions and ingredients for life to develop but also that it possessed them for longer than it took for life to emerge in similar conditions on Earth.
I strongly believe US will be able to pull off much more than said here.. cuz there are cold spots (~+25c) at venus .. now if that spot/region keeps changing position with day night then rover may have to chase that but even if there is tiny region which happens to remain between day and night that will be rovers spot.
Humanity just loves a challenge.
Yep.
Like coming up with acronyms for NASA missions.
Love that for us
Really bringing it with the awesome openings in the last few videos.... Loving it!
now I won't be able to stop thinking about Venus
And I won’t be able to stop thinking about your mother.
Well now I want a feet on a plate with onions and potatoes and some spicy sauce
"Shocking Blue" ...on youtube
Your list of questions towards the end of your vid is really good. Yes, it would be wise to invest more time/resources in studying Venus instead of much more distant bodies.

Venus rotates from East to West which tells us that it is upside down. I would love to see how this happened.
Not to be argumentative, my friend, but in space there is neither up, nor down. East and west is therefore irrelevant…., unless I’m wrong about East and West. Have a good weekend.
so theres aliens there then?
If we could speed up Venus it may have a good magnetic field.
We are upsidedown!
@@mathbrown9099 Let me know if Anthony has a reply, please!
I’ve been watching your videos for a long time, probably since you opened the channel and I got to say I love the new intros keep them coming
These videos read like a Starfleet mission brief and I love it.
Those were some VERY good questions you were asking at the end of the vid. Most time we just skip over Venus in discussions 😅
Imagine a completely inert computer that doesn't work on Earth because Earth is too cold and the atmosphere is too thin, but it suddenly wakes up on Venus. Material science needs to get on this!
What do you mean by "inert computer"?
@@johndawson6057 a computer that doesn't work at "room temperature be cause room temperature is too cold for the components to operate correctly.
@@milohobo9186 ...you know that there is much simpler ways to heat up something than going to Venus, right ?
Wait a minute, at 7:15 seconds he says they even got rock samples. How the hell did they do that? They can barely land a prob there but they took off with rock sample I'm confused 😅
The Russians got visual, audio, and compositional data I believe.
He seemed to have worded it weird, some Venera landers sampled/analyzed soil samples in situ, without return of course
Ypu have to be gay to understand i think
Probably meteors from Venus, like the ones from Mars, blasted away by asteroid impacts, drifted through space for several million years, then landed on Earth, probably on Antarctica. I assume the spectrums matched, so they were sure it was from Venus.
@@fredwood1490 using the words "probably" and phrase "i assume" lol take ypur beliefs vack to history channel where it belongs. Mainstream cs
We need to construct a strong artificial magnetic field in L1 lagrangian point between Venus & Sun, protecting it from the solar wind and radiation
.
After then terraforming Venus using Genetically modified Cyanogen bacteria will be a very easy task.
.
It makes so much sense to terraform Venus when compared to Mars 🤦
Before we turn Earth into Venus
There is probably too much mixing, due to high winds. But if there is enough nitrogen in the upper atmosphere, another probe could scoop it up into a balloon, which would float in the heavier, carbon-dioxide layer. The zone might even be habitable with Earth-like temperatures. A floating base might be able to extract elements from the upper atmosphere to sustain itself and grow in size, structure, and make hydrocarbons into more balloons. Aditional nitrogen could be extracted there using solar power to keep the bases aloft. Eventually, over the ages, carbon would be sequestered by floating plants, and the planet would cool.
Until then, we need diamond-based electronics or something that can withstand 900°F surface temperatures to send back data.
Unfortunately there is almost no known hydrogen (needed for water) on Venus :(
Water might just become one of the most valuable resources if we go to Venus
@@javant6993 There is sulfuric acid, which can be reduced to sulfates and hydrogen. There should also be some water in the clouds. It would be quite something if they were pure sulfuric acid.
1 day on Venus is 243 earth days. Good luck with that rotation
@@dylanhecker6686 Oddly, the atmosphere of Venus rotates about the planet about once every 4 days. But long days would be a problem for anything on the surface.
Nice to be early to such a great video
Great episode, Thanks.
I never really wondered about Venus until your Video, thanks a lot...now I'm mad at my government. Nvm, I'm always mad at my government lol.
Go Tesla woohoo ✋🎉 Musk-eteer Elon Musk for King 👑 Musk-eteer 🦮 Mars-bound woohoo
What if planets aren't all created at the same time? Venus today is how Earth _was_ way back in the past when it was _younger_ - and if Venus were younger than all the other planets it might also explain why it has no craters - maybe it didn't exist back then.
Venus has impact craters, same as all the other rocky bodies.
Venus may not be as boring as Mars, but I feel like Titan is where we should be truly looking.
its much too far away for us to seriously attempt a comprehensive exploration like we are doing with mars
NASA is thinly disguised, science-washed US military power expansion. We should be spending more effort looking at saving the Earth and not looking at planets, where we have no chance of living, for expansion. The survival of the human species has no chance if we destroy wherever we go.
Moon first 🌕

@@Damn-good-deal I’m not comparing the practicality of a Mars mission. Of course Mars is a million times more practical. I’m making a comparison between the cost to benefit ratio of a mission to Venus vs. Titan. I think Titan would be more rewarding. Obviously, it’s more resource demanding than a mission to Venus, but I think it’d be more worth the effort as well.
Excellent essay! You make a strong case for further exploration. Hopefully SpaceX will drive the cost of getting to space down enough to greatly increase the spending power of NASA for further exploration of our solar system.
Yes...and whales will grow legs and sing at times square.
Carbon capture blimps are probably the best bet. Once the carbon is out of the atmosphere, surface pressure and temperature will lower. The atmosphere is so thick that it traps the suns heat which is the problem. It’s the almost the same size, mass and gravity of earth probably our best bet. Also no oceans so that’s a lot of land for future populations.
The best episode you have done yet!
A Discussion of in a NASA Board room:
Ok, guys, we've got our cool acronym. Now figure out what it stands for and design a mission for it.
I'm so glad Venus is finally getting the attention it deserves. The obsession with Mars over Venus had a choke-hold on people for so long.
Great job covering this topic! 👍
Durrrrrrr im a bot durrrrer
Hopefully if we learn how to make Venus a hospitable atmosphere we will use the tech to fix our own first!!
Io perks up and says “Most extreme environment, whaaaa?”
While continued science performed, at Venus is desired, exploration of Mars is far more profound for humanities future
This was amazing. 😊 Great questions at the end. I didn't even know we still know so little about Venus. I truly hope it well get some more attention it deserves.
But hey! NASA and Musk are not the only one in the industry. Peter Beck is actually as interested in Venus as Musk is in Mars. And Rocket lab is a successful company developing it's reusable rocket right now. Can't wait what the future holds.
will it not have the parachute for the whole trip down?
We need to run a contest (if the cost of launching could be figured out) to see who can make the most indestructible probe as Russia was trying back in the day. I'd love to see how long one could survive with today's tech.
I honestly think Venus, Earth and Mars were all able to sustain life and that something clearly went wrong with Venus, even causing it to turn the wrong way, plus the run away greenhouse effect that took place. Mars, on the other hand, cooled internally due to it's smaller size and lost it's magnetic field, liquid surface water, most it's atmosphere, etc, but we all know that already. It's Venus I'm the most curious about. Sadly, due to how "new" Venus' surface is thanks to all the volcanic activity, I doubt we'll ever know what it looked like billions of years ago or if it did in fact harbor life at some point.
And, if we did in fact have 3 life-sustaining planets in our solar system, not counting any moons that may also harbor life, that makes me have a lot of faith in finding life out there in other star systems. Sadly, I probably won't live to see it happen, but it'll be an incredible discovery in the distant future.
Basically we have a planet next door where pretty much none of our theories hold up, ie we don’t see what we would expect to see. Not sure why astronomers have so much confidence in what they think they know
Smartest comment on here...by far.
I'm not sure what theories don't hold up, actually. I was under the impression most of the things astronomers say (that get reported) are personal interpretations or speculation.
From my perspective we simply don't have enough information to make a good prediction for what we should expect to see, but what data we do have is certainly very interesting.
A telescope just upended everything we thought we knew
It's a long journey just to return an overdue library book.
Thank you for being the first person to ask "Why does Venus have an extremally dense atmosphere, when it does not have a magnetosphere.?
Thanks for being the first person to put me to sleep tonight.
@@derrickcox7761 😆
Truly inspirational it would be great if all the planets are orbited buy satellites and deep space technology becomes accessible to everyone.
So, there are rocks. You asked a great question when you said we didn't even know what they were made of. Well, whatever they are made of is able to resist the temperature, pressure and acidic conditions of the place, so can we make things that mimic the durability of those rocks to survive and even function on Venus? Venus did, why can't we. I think there was an episode like that in TNG about that. Oh a humorous note, it's a shame we don't live in the 24th century where we could use Star Trek force fields to shove the atmosphere and ick away and create a garden-like environment. We did this with warp drive, cell phones, and iPads. Let's steal more from Star Trek! 😁
The Tandoori chicken on Venus is going to be amazing!
Excellent show! I'm hooked!
Lets go there.
You first.
Of course the extreme heat of Venus would evaporate the acid rain long before it gets to the surface...
It would be a cool mission but i also believe that pushing outward would benefit humanity a bit more
Venus could show us easier ways to break down Greenhouse gasses and change it into a fuel or transfer gasses to mars or even the moon to build up atmosphere
especially when we reverse engineer that new alien tech! one day we will be invincible
How you going to make a sustainable atmosphere on Mars when it has a very weak magnetosphere? Ain't happening unless you get that core spinning fast enough to produce its own.
@@caesarsalad1170Stop spreading misinformation. We can create our own magnetosphere.
@@MrNote-lz7lh I too, would hinge an entire planets population and infrastructure on artificial magnetic fields that could be destroyed in any number of ways /s
Venus receives 87% more solar radiation than Earth (per the inverse square law: 1÷(0.73×0.73). Venus is 0.73 AU from the Sun.) When the Sun was young and emitted only 70% of the radiation it does today Venus still received 31% more than Earth does *today* (1.87×70%).
They might find life in the upper atmosphere so they don't want to go. Wouldn't want to hurt the "narrative" VS James Webb which is looking at things so far away it would never prove life elsewhere.
Been waiting for this
2:15 It's actually quite low in viscosity despite the pressure due to the high temperature.
5:55 - 25mph impact speed seems a rather low optimistic estimate. What's the source?
They're going there to get Tibiana Gas for the Navy's anti-air blasters.
Totally agree Venus is very interesting planet we should explore it more. Learn how it works maybe there is life too.
Fsacinating stuff!
man it woulda been so cool if venus had a shitload of life hidden under those clouds
Impossible
Excellent video! People need to be taught these facts. Yes Mars is more "hospitable" for a colony but we aren't likely to learn much more from Mars. Venus on the other hand...
No need for parachute. Any object will slowdown and if it resists in the end the pressure will be like 1000 meters under water, you gently descend and touch the ground.
Venus is absolutely not what we have always been taught it is.
"In the late 1950s NASA was formed to compartmentalize, containerize, and sanitize information from all space platforms and vehicles. We sold NASA to the public claiming that all information would belong to them but they got very little and even that was highly sanitized.
Our first efforts were to keep the public from learning about Venus. A very similar planet to Earth and it's population is very similar to us just technologically advanced.
We have learned a lot from them starting with the Russian Venera I and U.S. Mariner II, we made Venus look like a lead melting, volcanic surface, spewing sulfuric acid into a pressurized atmosphere 90 times that of Earth.
And as often the case we over did it and we wondered why nobody asked how a parachute survived a descent into 800° air."
(John Lear's disclosure briefing November 2, 2003)
Mars is smaller but also is earth-like. Obviously much more problems on the surface of Venus than Mars. To call Mars boring is ridiculous.
This really shows us what earth could be like if certain situations occur & cause certain run away effects. That change the composition of our planet forever. Like a Super reverse ice age.
It can be anything. Its pretty magickal. Science wouldnt explain it tho... shhhhhhh
What is the pressure and temperature on the higher peaks of Venus.
Almost as hot as Trump’s toupee.
Cloud City needs a Lando to run it.
respect
We need some material science for this trip. The computers don't need to work under Earth pressure, temperature, or atmospheric conditions
Just launch a fleet of spacecraft to assemble a giant sunshade to cool it down and then start the terraform process
Yeah, that will only take 60 million years to cool down. Great plan.
@@LemonsAndSalt69 its a start ! Whoop whoop !
@@LemonsAndSalt69 not with lemons and salt.
The heat on Venus doesn't come from the sun. The global cloud cover of sulpheric acid has a high albedo that little of the sun's light makes it down to the surface. The heat comes from the formation of the atmosphere. When the atmosphere was forming and was getting thick, it was compressing. The heat comes from this compression. Because of how thick the atmosphere is and the fact it is made of carbon dioxide, the heat can't get out.
NASA love love loves their acronyms (awesome cool really outstanding names your mom says)
A centrifugal ground base AI resource sling shoot with robotics and a space net space elevator with a space centrifugal counter weight to speed up or slow down to counter balance. All could be done to make space city's.
IN SPACE Magnetic motors could be used as a resistance braking system as well as regulatory power controls even intuitive internal and external tools and upgrades of living systems or tools and factory's the other side farms and farming, aluminum metal glass self repairing system and drones even AI. People should be able to invest rent or apply for a add on of any upgrades do to life support systems and some day people affordability for vacations and travel even possible living. Just think space cars and a light suit air regulated, travel could be fast and easy with flying cars and self driving vehicles.
At this point i learn they kind of make somthing like if it c02 maybe they can make oxigen soo its pretty cool
Agree
"Kinda hoping" lolololololololollololoolololol
I just had a vision of folks living in the floating cities of Venus lowering ropes with special pizza boxes down towards the planet to cook them 😅
BS. The Magellan spacecraft imaged the planet in high resolution (100 meters per pixel is VERY good resolution). This was significantly better than either Earth-based radar or the surface radar mapper from the Pioneer Venus orbiter (7 km at best). This was done with radar and not optics, so any comparison to data obtained by imaging spacecraft for the moon or Mars is irrelevant. It would be nice to get another look at Venus with 15 meter per pixel resolution, but that does *not* make the Magellan mapping results "fairly low resolution".
I strongly believe US will be able to pull off much more than said here.. cuz there are cold spots (~+25c) at venus .. now if that spot/region keeps changing position with day night then rover may have to chase that but even if there is tiny region which happens to remain between day and night that will be rovers spot.
As a cook I''ll just say that proper temp for an old school brick pizza oven the temp should be between 650-750F. So Venus would not be good for pizza.
There are several missions to Venus that are planned:
2024 - India's Shukrayaan 1 will bring a orbiter and an atmospheric balloon.
2025 - Rocket Lab/MIT will send an atmospheric probe
2026 - China's VOICE a orbiter
2028 - NASA's DAVINCI a probe and an atmospheric probe
2029 - NASA's VERITAS probe
2029 - Roscosmos's Venera-D probe and lander
2032 - ESA's EnVision orbiter
Lots of cool things to be excited about!
Me too
Venera 13 last about 120 minutes...excellent work by Russian scientist and engineers.
Great videos man.
Dur im a paid bot durrrrrr
hi
The problem with Venus, excluding floating cities and the enormous resources it would take to remove and change the atmosphere, is that it takes the same amount of fuel to leave it’s surface as it does Earth’s. But of course if we had the power to make it livable we’d probably have that figured out too.
Coolsies thanks mate 👍
Well Done thank you.
If earthlings aren’t traveling to Mars..Venus or anywhere farther than they have already then how can we confirm (truths/facts) from spacecraft/probes etc?
Could we just pull Venus back a little bit and pull mats a little closer so temperatures get better? We just tie a rope between the two
Don't know much about orbital mechanics, do you?
@@craigcorson3036 dude I’m an orbital mechanic just like my father and his father before him 👨🔧
Still waiting for them to visit Uranus and explore its gaseous nature.
You're right. Why travel all over Mars? When it all looks exactly the same. lol
How long would this lander last before it is destroyed? So not long if at all.
Pretty sure that's Kami's lookout in the thumbnail.
I saw a documentary that earth also went through a stage simmular to Venus, where the waters turned acidic and most of life diedout, maybe it could just be a simmular phase which would correct itself, just would probably take a very long time. (just speculation)
Take me to europa. I wanna see subsurface seas.
It's funny to hear how the military is looking for something "new" on all the planets destroyed and abandoned by civilizations. Also check Phaeton.
Take your meds, dude.
My question is, If Venus atmosphere is so dense and thick. How is it, that a space craft crashes on the surface? Wouldn't be like sending a probe to the depths of the ocean. A probe sent to the depths of the ocean would settle gently because of the density and pressure. How does a parachute or ballon withstand the intense pressure? And why would you even need a parachute? Would you use a parachute or ballon, to send a probe to the bottom of the ocean? Some on smarter than me please answer my question. Thank you.
It would depend on the atmospheric entry angle and the velocity of the space craft. If the space craft has to high of a velocity, the atmosphere won't be able to slow the craft down enough. That's were the entry angle plays into this. If the angle is staight down then the craft won't spend enough time in the atmosphere to slow it down. If the angle is shallow enough, the craft will spend more time in the atmosphere slowing the craft down.
Exporting valuable minerals from Venus could be one good reason to investigate.
Which rare on Earth isn't rare on Venus.
And what mineral is that ?.
Whoa whoa whoa whoa whoa! At 7:17 you said we got _surface samples_ from Venus!? How in the hell did we pull THAT off? Or do you mean we drilled out a cylinder and sent back a handful of crappy photos with 80's tech? Surely we don't HAVE surface samples!
I hope Venus is terraformed and we could have two Earth-like planets right next to each other. One day we may have the tech to pull that off.
Earth has a bigger core than venues which gives us a dynamic crust that captures co2 ete and all that is because we collided with a planet the size of mars in it's early formation, the surface is most basalt lava and the winds come from the sun.they are still volcanoes erupting on Venus, and IF venus had oceans like Earth then all that water vapour would count for the atmosphere depending on when it lost its magnetic field, if it lost it recently say last 100m year's then we can count for the atmosphere
One reason for NASA spacecraft going to Venus again is we've used up our 21st century Venus transits (2004, 2012) and another pair will not come again until 2117 and 2125.
Hahaah nasa. .. na son
Dang...was hoping to get a transit pass for 2024.
I love Him 💚
These questions actually do not need to be answered at all. It's not like we're going to terraform it.
ask Dr. vicki hansen about venus. she is a planetary geologist that is a specialist on surface mapping of venus
Personally I always thought Venus was the better long term plan for us inhabiting another planet, Mars has a lot of things going for it but its main detractor is a pretty big deal and that is the lack of sufficient gravity to ever hold an atmosphere, Venus on the other hand could be cleaned up in theory, we know it can hold and atmosphere we just have to make it one made out of friendlier stuff and a lot less of it.
If we´d had evolved 1b years earlier. Maybe.
But we didn´t.
