Why is It So Hard To Get To Jupiter's Moon Europa?
HTML-код
- Опубликовано: 6 июн 2024
- Europa is one of the four largest satellites of Jupiter, known as the Galilean Satellites, in honor of its discoverer Galileo Galilei, who discovered them by looking through his telescope in the year 1610.
When Galileo discovered these satellites, he did not imagine that 400 years later, enormous water reserves would be discovered in this place. Today, it is known that Europa is one of the bodies with the most significant amount of water in the solar system and that it could even have all the conditions to host living beings.
But... If it's such an essential place for the search for extraterrestrial life, why haven't we been able to send a human-crewed spacecraft to explore this frozen world better?
Why is it so hard to get to Europe?
Stay with us to find out!
First approach
On March 2, 1972, the Pioneer 10 space exploration probe was launched from Cape Canaveral. This spacecraft was part of a NASA program that aimed to take advantage of an alignment gap of the outer planets to explore the solar system's gas giant planets.
The Great Find
However, the Pioneer 10 and 11 probes were much more fruitful than initially estimated. The Voyager probes would give us the probes that could best reveal the secrets of the Jovian system.
In the 1979s, after the apparent success of the Pioneer probes, NASA proceeded to
A new goal
The two groups of probes, Pioneer and Voyager, initially aimed to take advantage of the approaching gap between the gaseous planets to explore them all and, in the process, take advantage of the momentum they would obtain to leave the solar system.
But during those trips, images and data from scientific instruments showed that Europa had a much cleaner surface than expected, meaning that it didn't have many impact craters.
2016.
The best-case scenario
As you can see, a trip to the Moon Europa would not be accessible with modern technology. To undertake such a long journey, it would be best if astronauts could make brief stops at other places, such as the Moon, Mars, and Ceres, the dwarf planet in the asteroid belt.

Because we were told not go there. “All these planets are yours, except Europa. Attempt no landing”. Really clear message some 14 years ago.
From who
Well said.
Default reply for any mention of Europa.
Is this from Destiny?
@@blairmarshall544 From the movie 2010
Why is it so hard for me to get outta bed in the morning??
Gravity
gravy
Yeah! And why, when I hit the snooze button which is supposed to give me 10 minutes more sleep seem like only a few seconds have passed from hitting the snooze and the alarm going off again? Hmm???
Now this is the question I want an answer for myself 🤣🤣
@@ketikatz pardon me but you’re absolutely stunning
The trip would be totally impossible because of just one reason that is totally neglected in this video: Jupiter's radiation. 540 Rem to be exact per DAY slams on Europa, while here on earth the average is about 0.620 rem per YEAR. Good luck with that.
Radiation could actually be beneficial for the begging of life
Excellent point.
Orbital Mechanics and the greatest fuel assist ever created moving at .01c with the radiation shielding tech we have now would get you there.
Why are you using rem instead of millisieverts?
Anyways, 540 rem is 5400mSv per day. Just staying there 12 hours has a kill rate of 50% with a month. 100% in 2 years.
Getting to Europa with "a spacecraft": Not a problem
Getting to Europa with a spacecraft carrying a "living payload that doesn't need to come back"D A lot harder, very expensive but doable if we really want it.
There and back again: Improbable, very very expensive, crew would probably need to spend months readjusting to gravity upon return including mutiple other health issues resulting from prolonged stay in space. Not feasable until we find faster ways to get there... and back again.
And let's not forget about the intense radiation on Europa due to Jupiter's magnetic field.
@garryvanamburg5684 yes this is often unmentioned in these threads and one of the biggest obstacles besides just getting there
That's why we need to find where the Millennium Falcon is.
My biggest concern,after how to get there,would be how to mitigate the immense radiation given off by Jupiter. I believe that Europa is tidally locked but it would still experience high levels of radiation even on its far side from Jupiter.
Shielding from Jupiter’s intense radiation is indeed one of the biggest challenges. Scientists are exploring innovative materials and technologies to protect spacecraft and potentially humans on Europa’s surface.
Two main ways
1. Thick radiation shielding around the electronics
2. Highly elongated orbit that keeps it out of the radiation belts most of the time and gets it through them quickly when it does swing by close for a Europa flyby
Edit: this is just for the Europa Clipper spacecraft, manned craft will be much more challenging
The answer is to skip Europa and go to Calisto instead, outside the radiation from Jupiter's magnetic field. Everyone talks about Europa, but Calisto may also contain a sub-surface ocean and definitely has surface water. If NASA could fund a crewed mission to Jupiter, Calisto would be the target.
That's why we need to find where the Naboo Royal Starship is. Some people say that it's buried in Antarctica.
It's more likely that we will send
AI robots for space exploration, this will also reduce the need for supplies.
If i live 30 miles away from my work, and i drive 30 miles an hour, i can get to work in 1 hour. With the knowledge my house and my work never move. Earth and europa are in constant motion. So if i leave earths atmosphere at 30 mph and the earth and europa are moving at 29.5 mph. You will get there at a snails pace. Our technology is far behind our dreams of the future.
because Earth is moving faster than Jupiter, Europa is literally running away from us, or Earth from Europa.
Your description would be more accurate if Earth was moving at a 30km/s and Europa were moving in different (!) direction at 17km/s (in our perspective (orbital speed of Jupiter is 13km/s)) while also orbiting Jupiter in 580-970 MILLIONS of kms away from us
Right, let's just avoid the 51,682 km/h we could achieve 50 years ago... LMFFFAAAOOO 🙃
@@ssenylit's impossible for something to always be "running away from us" with a circulatory system... there's a minimal and a maximum distance, kinda like the distance to Jupiter you used to support yourself a few words later. You sound like a pessimistic hypocrite.
@@tankeater Wow, rude, when i said "running away" its just not a representation of circulatory system, its more like representation of this by two infinite straight parallel lines where Earth and Jupiter are moving in same direction, with earth moving way faster than Jupiter.
From POV of Humanity, Earth *feels* like a stationary object, with Jupiter moving away at 17km/s .
I also agree that this is not a useful idea, representation, and so on, its just a funny thing to think about
@@tankeater "Its impossible for something to always be "running away from us" " Dont forget that universe and its entire fabric of space and time is constantly expanding, just saying
Alot of people mistakenly think it would be easy to get to another planet in the solar system and while we could probably do it if we spent a huge amount of resources there are a few big problems. 1) Distance even with our fastest rockets it would still take multiple years each way. There is no friction in space so you can attain a high velocity but you still have to burn alot of fuel to accelerate to that velocity. A fusion or antimatter rocket would get us there alot quicker than a traditional chemical rocket. 2) Radiation - the space station is sheltered by Earths magnetic field outside of this field you'd get a lethal dose of radiation within a week or two, within minutes/hours if a bad solar flare hit. You could protect the astronaughts if you covered the ship in lead plates but that would make the ship heavier probably too heavy to get out of Earth orbit. 3) to survive that long in space you'd need to grow you're own food and recycle the air/water with 100% efficiency. Our air/water recyclers are good but not 100% and I don't think we have successfully grown crops in space. 4) Lack of gravity - Human muscles and bones weaken quickly in zero G when the astronauts come back from weeks in space they are so weak they can barely stand. Spending years in zero G then coming back to Earth gravity would probably kill you and the ship would need to have some artificial gravity. 5) I'm not sure you could grow anything in Martian/Europa soil because even if you moderated the temperature, added air and shielded the plants from radiation the soil still wouldn't contain the nutrients and chemicals Earth Plants need.
A Large pulse fusion rocket that could apply a smooth and constant 1.2 G acceleration could solve a lot of problens on a trip like this.
You missed something that everyone does. You also need a lot of fuel to slow down to an appropriate orbit. Then you need a lot of fuel to return.
It would be easy if we're willing to learn from Han Solo.
No lead but water as a radiation shield. Lead makes deadly shrapnel when hit by cosmic particles. The water is needed anyway for food.
My favorite part about Europa is those guitar solos. Great song!
Ah, no, you're thinking of the place on Earth that is also a band: Boston.
Santana. You have a wonderful tan man.
@@sarkedevBoston did have the third stage though. That was good for space travel
Great video and information !
Thank you!
Space is so big we really dont understand it it takes so long to get anywhere traveling at a very high speed and still n9t get out of our solar system
I dont care what anyone says, Pluto is a planet and will always be a planet to me
Because it’s far away.
Yes. That too 😂
There is a ferry from Dover!
I love all of the space videos you make
The issue with travel time is based on how we propel our spacecraft. If we could provide constant thrust to accelerate much more, ideally halfway there and then decelerate the other half, it would take far less time. The scifi book/series The Expanse shows how changing the ratio of fuel use vs. thrust would open up the solar system.
I actually thought there would also be mention about a faster spacecraft having to slow down to meet up with the satellites of Jupiter. The New Horizons probe shows how using conventional propulsion and slingshot techniques to get us to far out places has the price of the encounter being brief, Pluto's flyby being a matter of minutes for the closest approach.
Its a weird premise for a video. Its not like its the late 21st century, and we have thriving outposts on Mars, or even the moon for that matter!
We will never get to Europa.
Robotic missions like Mars rover yes. Manned missions, nope. Deep space travel and especially interstellar travel is a fantasy. Not going to happen.
@@nateg08 I was obviously making a tongue-in-cheek joke because the theme of this channel is: "Everything is impossible."
You can't apply absolute certainties when it comes to the future. There was a time when flying was considered something that only stupid people would actually attempt. Still, people continued fantasizing about it. I remember watching Star Trek in the nineties and fantasized about tablets and handheld scanners. That was a time when monitors were actually based on cathode ray tubes still. And in electronics I remember using green and red LEDs, or a combination of them because blue LEDs didn't exist. Now decades later, we are using handheld miniaturized OLED based screens making use of quantum-level effects that were unthinkable of just about three decades ago.
From our current perspective, many things are impossible because simply we don't have the knowledge and technology for it. Just like back then. However, we don't know what discoveries we will make in the future. Sometimes technology makes big strides, sometimes it takes a while, and you never know what impossibility becomes normalcy next. It's true that there are many hurdles to overcome, but unless they are founded in barriers placed by the universe itself, it could as well just be a matter of time. In the Medieval age it was common doctrine that man knows everything there is to know and that everything to be invented has been invented. From the perspective of a Late Medieval era man, the idea of a flying passenger airplane or the internet, are things that will never happen. Especially the latter with being an esoteric concept from his perspective. Imagine what esoteric concepts we will have in 200-300 years.
I have been there. Not cool. Very gay time.
@@nateg08I agree. I believe that is the answer to the Fermi paradox.
We haven't seen any aliens because interstellar travel is sooo impractical it's impossible. Unfortunately we will go extinct in this solar system.
@@nateg08 No. Not even robotic missions. It will be forever impossible.
Hard enough to get to our own moon
Especially considering it still hasn't happened 😂
Thank you for an informative video. Could Europa be a place where part of humanity could stay when sun expands into red giant, or gravitation and radiation from Jupiter won't let it happen without huge leap in technology?
whoa I can imagine how much delta V required just to orbit Europa. I only can do multiple Europa flybys and only 15 m/s dV remained in the probe.
I expected at some point that "we cannot land on Europa because we can contaminate it and don't want to." But instead got a thorough analysis of the challenges of bringing humans this far out in the solar system, which was super interesting. However I think the contamination issue would be valid, Nasa didn't want to approach one of Mars' riverbeds for this specific reason. I'd have to look up the details of it.
Water makes it likely there is life? LOL
I wouldn't say likely, possibly maybe.
More likely than a planet without water
The way I tend to explain it: Getting into gravity wells is as much work as getting out of them. Understanding orbits requires letting go of the idea of "falling." That's not a real thing. Delta-v doesn't fit our instinctive experiences very well.
They don't wanna send anything to land there because then we'll have undeniable proof of life outside Earth. That's why they burned the mars samples on the viking missions
What part of "ATTEMPT NO LANDING THERE" was unclear???
Am i the only one that caught that he called europa an "artificial satellite?"
This channel is all chatGPT brugh. AI generated voice, chatGPT script.
It's quite hard to get even to the moon and it's very hard to get to mars so imagine what it would take to send a manned craft to Jupiter's moon which is much further than mars.. It all comes down to technical difficulties in sustaining a human being for such long journey.. This is so obvious that the further we go, the greater the technical challenges..
Absolutely, the challenges of deep space travel are immense, especially for missions to Jupiter's moons. Advancements in technology will be crucial for overcoming these hurdles.
Not only are there technical difficulties to keep people alive like you said, but also a huge financial challenge even if you solve the first one
Because the bus service is rubbish, only 3 busses a week.
My takeaway is that before we think about going anywhere and doing anything else in space, step 1 is to create a space infrastructure. I guess that would really be step 2. The REAL step 1 is to think of a way to make the create of a space infrastructure financially profitable.
.
I've learned that there is no end to the lengths humans will go to for money, sex and power.
You are correct but there's a big problem. Creating a space infrastructure will never be financially profitable.
If you can get to Eve, you can get anywhere in the solar system.
Err, Venus.
A trip to Jupiter takes 8.5 years...a trip to our Moon it takes around 3 days....why would you even need a pit stop so fast and early in a journey?
Imagine if the ship to Europa can split into several modules and launched at the same time.
Each module will be so much lighter, and thus, faster.
And those modules have the capability to be joint together (like Megazord of the Power Rangers).
It will be much easier to get to Europa when the bridge from Earth to Europa is finally finished.
Missed a chance here, the arrow in the thumbnail should start in Europe, so it could connect Europe and Europa
We don't seem to be able to get back to the moon, let alone create any type of base on the moon. So I think we are talking about another century or two before we could even think about landing a man on Europa.
How exactly a planet's gravity is used to propel a spacecraft further into space.... I thought gravity attracts other objects and not "push away" .... please explain!
Bros can’t even make it to the moon
Betcha I could make it in Uranus brugh.
Without watching the video yet, the same reason it's so hard to get to Mercury, I'm guessing. When flying to land on or orbit Mercury it is incredibly easy to get caught up in the Sun's gravity, and if that happens, poof! You have a very expensive cinder. Jupiter is the second most massive object in the solar system, by a great deal above #3, so flying close enough to Jupiter to end up at Europa is difficult for many of the same reasons.
There's a reason why most of our dedicated Saturn probes, and all of our Jupiter ones, have been orbiters rather than landers. If you're trying to orbit a gas giant, you can basically just fly into its system and it does most of the orbital insertion work for you. From there you can tweak your orbit to set up fly-bys of various other moons and points of interest. For landing, or even for orbiting a moon, you have to slow down quite a bit, and then it's like trying to swim slowly against a strong current. The river of Jupiter's gravity is generally going to take you where _it_ wants you to go.
Also you would have to fire slower heavier rockets ahead of time carrying extra fuel and supplies
With current technology it's impossible .
Not to mention the amount of radiation waves that will be blasted onto a human crew, not just from the Sun, but also from Jupiter itself. Those guys would be so miserable, they would be willing to just die there.
You're right, the radiation would be a huge challenge for any human crew. Both the Sun and Jupiter emit intense radiation, making it extremely tough for astronauts to survive. Proper shielding and protection would be essential for any mission to Europa.
A heavier spacecraft doesnt mean a longer travel time. This is nonsensical. In the vacuum of space, once a spacecraft is in motion, it will continue moving at a constant velocity unless acted upon by an external force (Newton's First Law of Motion).
The mass of the spacecraft affects the design and fuel requirements but doesn't directly translate to a longer travel time in space, provided the propulsion system can compensate for the mass difference.
The question of "why haven't we sent humans there" is sort of ridiculous. The only extraterrestrial body people have ever been to is the moon, the closest place to us. Even doing that was a struggle, only a dozen people have ever been there, and we haven't been back for 50 years. We haven't even gotten people to MARS! Why would we jump from the moon, past mars and the giant gap that is the asteroid belt, and go to a moon of Jupiter?
This question would work much better if you were asking about sending probes there. Even that would be the farthest we've sent a landing probe by far.
Theres only one reason...the rocket equation.
To get to jupiter you need a very big rocket. To get there with enoigh fuel to also enter orbit of a moon and land on it you need an even bigger rocket.
It would be immensely expensive and complicated.
And then on top of all that europas ice is miles thick so you need some way to drill into them
It's already hard going to Mars haha
Do more research
Jupiter emits a very high level of radiation, primarily from its intense magnetic field, which traps and accelerates particles. Europa, one of Jupiter’s moons, is subjected to this harsh radiation environment. The radiation levels on Europa are extreme, estimated to be about 5,400 millisieverts (mSv) per day. This amount of radiation is more than a thousand times higher than the average dose someone would receive on Earth in a year, making Europa an extremely challenging environment for potential robotic missions or any form of life as we know it.
At 5:39 he says “…and this was something completely new since, until then, no known *artificial* satellite showed geological activity.” ISS is an artificial satellite; Europa is a natural satellite 🤦🏻♂️
Hard to get visa?
ISRO has started planning a mission, they are targeting by 2035.
We all know the real reason why it's so hard to get to Europa is frontex
As we develop and improve nuclear/ion propulsion. The trip is possible. And very probable in the near future.
All the more reason for the importance of finding a better source of propulsion…
water=life? . Water is indeed nesessary for live - but that is only 1 condition of millions - Indeed to have life you have to find exactly combined places like our earth, moon, sun . jupiter etc. - And the only place for life possible to be found would be that twin earth.
Maybe there's another form of life we don't know
Plate techtonics in artificial satellites -- had never heard of that before. I think it's not a thing.
It may sound surprising, but plate tectonics can indeed occur in artificial satellites
@@InsaneCuriosity Are you an AI generated voice piloted by chatGPT? Tell me the truth.
It is a thing. Educate yourself.
@@user-ln1ec9qr5y I did look it up, and from Sputnik, to Telstar, to weather satellites, to Starlink, none of them are geologically active or have ever had plate tectonic activity. Maybe Europa and Ganymede, but those are natural satellites, not artificial. If you are able to pay attention, you will have noticed that the narration talked about ARTIFICIAL satellites having plate techtonics. Mine was a commentary on that error, one that you repeated after not noticing it to begin with
I didn’t but now I know why now
Me as a United fan this season
At this rate of technology you dont have to launch humans, its best to create A.I bots and explore europa
Short answer.. it's far
The worst part isn't getting there, if you send humans there they will quickly die to radiation.
Jupiters radiation belt is kinda insane.
If you are an AI voice with thoughts generated by chatGPT (like this channel's content "creator") radiation is no big deal brugh.
Then you won't have to be concerned about fuel for the return trip.
Cause it would take 8 years. That's why.
why it almost sounds like markiplier "Almost "
Wouldn't it be more likely advanced robots are sent in the near future rather than humans?
That's my thought. Robotic missions like Mars rover are far more likely. Man will never set foot on Europa. Deep space travel, especially interstellar, is a fantasy.
Yes
Uhhh, because it orbits Jupiter?
Why you always have to do pluto like that !😂
So hard to get there and yet in yr 1600 that guy can see Europa 628 million km away ..
Well, yes....and we can see other objects billions of light years away. It takes 3 days to get to the moon and you can see that with the naked eye. You can see a mountain from a hundred miles away, how long does it take to get there in a car??What is your point?
I think we were never meant to visit any other planets. Hence why galaxies are so far away. Our creator wanted to keep all simple and keep everything or anyone in it’s galaxies so there no interference and no one trying to rule all….
We could not even get to Jupiter let alone aspire to reach to a distant star. Humans are intelligent but that does not mean they can achieve everything. Certain things are off limits. No matter how much we grow as a species, I believe Interstellar and intergalactic travel are permanently out of reach. We cannot do it even in a million years.
I agree. That is the solution to the Fermi paradox.
Ima save you 12 minutes: why is it so hard to get to Europa? It’s FAR
Europa is known in ancient mythology as "modern Atlantyda" 👀ツ
If a space mission to our neighbour planet jupiter will take 8.5 years, how can we talk about missions to proxima centauri 4 light years away?
We can't escape solar system what are you on
@@milashah8902 we sure can mate
We will never be able to reach proxima. Not even in a million years of growth as a species. By then we would be long extinct by our own fault. Our beginning and ending is already written by our beloved Sun. Optimistic attitude will not solve human limitations.
It's easy to talk about. Doing it, well that's another issue.
just send supplies ahead. a supply ship could be orbiting europa when astronauts arrive. 🎉
Why is it so hard to get to europa? Because it's far. We can't get to mars with manned flight and likely can't even go back to the moon today
What? We sent probes to the moon like a year ago. Getting to the moon is easy.
We could send people to Mars also, it’s just that the risk is high.
Maybe because the tech to get there is being suppressed.
Because it is toxic outside of the Earth's atmosphere.
Inside me ma's bee whole is also Toxic is what me pa says to me.
First time to your channel. So disapointed with the robotic voice.
not hard to get to Europa if you send a satellite there instead of a manned spacecraft.... as far as im concerned, we sent a flyby to take a photo of jupiter years ago and we had huygen land on titan in 2005. So, it shouldnt be that much harder to land one or orbit Europa
Wdym? I live there🤨
why is it so hard to get to the moon
Basically we can’t go….😂😂
Because it’s so far away…
If we took all of the money and resources that we've used for waging war on each other, we'd already have space bases on every planet....
Great point!
Not likely. Probably the moon for sure. Do the math.
Humans haven't even successfully traveled to Earths moon yet, so why even bother asking about Europa?
What about nuclear fuel
few centuries.
Anyone see the movie Europa Report?
because it is not easy
Because they have seen what we have done to our Earth,why would you invite your neighbour over if you knew the damage he was capable of.
But return journey should take less time.. As we are going towards sun in that case.
Why is it so hard? Spoiler alert. It's very, very, very, very far away.
I have the solution….
Solar panels and a Tesla fully stocked with Coors Light.
That won't work. You need Heineken.
@@user-ln1ec9qr5y Heineken is too heavy. Too much mass. You need something lighter.
Fund NASA as much as the Army is funded and we’ll be able to get Europe in the next two generations
😂😂😂 NASA already taking billions for things they are not doing but doing on paper
We already made it to Europe. 😁
Too much radioactivity
to go to europa you need to change the language to spanish and go to europe

what a dumb question, why we havent been in the europe yet?? brother we just landed on the moon with insane luck and you want to travel literally to the edges of our solar system
