Most people do not understand that for all of the planetary missions, most of the trip requires no fuel for propulsion. It takes a large rocket to get off the Earth, and there are small thrusters to control attitude and course corrections. To orbit another planet we have to fire a rocket to slow the vehicle down and be captured by the planet. Additional burns may be used to circularize the orbit or change the orbit. Most of the trip is just coasting around the Sun like the other planets do. To go directly would require far more rocket fuel for the trip and the orbit insertion.
Don’t forget that you might want to come back as well. The initial liftoff has to lift all that extra fuel weight, so the increased fuel requirement would be far greater than just the fuel needed to enter orbit at Jupiter and return based on the weight of a one-way nonstop trip.
You did forget one other quite important issue. Our bodies are not made for long duration in space. Even a trip to Mars is a suicide mission if we don't design and build a space transportation system that has artificial gravity. And we know only two ways to do this. 1. Building a rotating space station, which would be immense and almost impossible to build. Because we could only build it in orbit. 2. A rocket that has non-stop propultion to create artificial gravity. (The idea of a accelerating car) So unless we overcome these issues first, the moon will be our end goal. Musk can dream all he wants, but no human will ever reach the moon with one of his rockets. And not because of the rockets not being good enough. But our bodies are not up to it. Simple as that. We have done enough experiences on astronauts and cosmonauts after long space duration in the divers space stations to know this.
Humm, if I remember correctly, you can orient a "slingshot" maneuver to slow down rather than speed up. Been a long time since I played with orbits in Kerbal Space Program, though.
If Humans ever go to Jupiter in person, it will likely be after they've developed faster ships. Even if they could cut down the trip to six months, then it's doable, if they have a way to protect themselves from the radiation.
Maybe we can send life like Avatars and enjoy them in Virtual Reality's. Maybe, Musk has thought of that for colonizing Mars instead of just A.I. Ah Damn. It won't work in real time but we can watch the replays and let the robot do the driving. Nice thought though. Oh Well. We need Fusion now and Helium 3 from the moon.
@@davidmacphee3549 - Thing that tends to get forgotten - we have no FTL communications any more than we have FTL propulsion. Any VR is looking at a significant delay. It would be like trying to play an MMORPG over a dial-up connection. You would be looking at a minimum of a one hour time delay for every single round trip data transfer. Even the delay to the Moon is noticeable, being nearly a second and a half each way.
@@daniels7907 Yeah I know. We could do it across town okay but Mars? Well, if only it were possible it would give a whole new meaning to 'Working from Home'.
I don’t think it would be a viable trip unless the spacecraft has a way to slow down on its approach to Jupiter. We cannot feasibly support a 6-10 year trip for a full crew to Jupiter. Propulsion tech would have to dramatically improve before we could send any living human there.
You could travel to Jupiter in less than 18 months if you departed from lunar orbit utilizing propellant originating from the lunar surface. But you'd have to manufacture propellant on the moon, Callisto, to return back to cis-lunar space.
So whats our best our option? 1. Go straight there, slow down for orbit 2. Gravity assist venus, mars & earth to speed up & some how slow down hard to orbit 3. Go really slow to orbit easy then I guess use Gravity assist from the moons & others to get home quicker for all 3 options
Be worthwhile to send some supplies ahead. Supplies orbiting Jupiter and some on Callisto. Or even a base pre sent to Callisto. If there was a mission, might make it worthwhile to land on one of the moons that's possible to due so. Then pick up some samples to bring back. Might be an idea to send an RTG craft to Jupiter that can mechanically divert some smaller moons to crash into Callisto. Giving it more mass.
How would giving Callisto more mass accomplish anything other than disrupting the Jovian moon system? You seem to forget that more mass equals more gravity - and gravity has infinite range. So you cannot increase the mass of a moon or planet without also altering its orbital characteristics. Plus, NASA only just made a very slight modification to the orbit of a very small asteroid. Where do you think that the money will come from to pay for all the stuff you are proposing here?
Callisto is far away from Jupiter. At it's slow rate of accumulation and that other celestial bodies get pummelled with asteroids with little to no consequence it should be fine. NASA has spent money on worse ideas.
Agreed we can do a lot more if money was not a factor . I mean right now Jupiter could pull mercury out of orbit and screw us all if it’s right . We need to be multi planetary . It’s mars then titan the gas station . That gives you range and less weight to haul
If nasa could have a budget equivalent to the military for just a few years, we’d make some actual progress. At this rate, I wouldn’t expect any viable propulsion systems capable of traveling in space for prob 50-100 years
The technology doesn't exist. Would you get on board a ship that is no bigger than a tin can and then spend the best part of 20 years on it? Sending women would be a better idea. You put men onboard and confine them for years they will eventually turn on each other. You will get on each other's nerves and something will give. What we should be researching is suspended animation. If we could put humans to sleep and suspend the aging process that would greatly reduce the need for tons of food, water and air there and back.
More money means more efficiency. What a stupid world view. Musk made much more progress himself with his company than this state driven money burning machine.
@@daviniarobbins9298 The hell are you talking about ? Guarantee you women wouldn’t last 2 days together without starting drama and gossiping about Kim kardashian 10 million miles away from earth
@@daviniarobbins9298 "Would you get on board a ship that is no bigger than a tin can and then spend the best part of 20 years on it?" Why would you think a capsule would be used for a trip to Jupiter?
This is probably at least a century out. You would need a spacecraft larger than the ISS and a lot of technology that we simply do not have yet. Traveling to Jupiter in free fall like a space probe simply will not work for a manned mission. We will need active propulsion. Solar power will not generate enough electricity so far out from the Sun to provide support for a human crew unless the solar panels are unreasonably large. So we would need to look at nuclear power. It would also be likely that we would need to send supplies, equipment and plenty of robots to lay the groundwork for the arrival of a human crew. It will be a massive undertaking and our current economics are not such that we could really do it. A lot will need to happen first.
@@TheMadridTv - One can never assume what future generations will do. I grew up in a time when we were warned that household chemicals were unsafe to consume. Decades later you had people eating Tide pods on social media.
I doubt that manned missions beyond those to the moon will ever occur. There are far too many costly hurdles to overcome, and too many problems to address here on earth.
Very good video, BUT..... at 3:15 the Voyager and Pioneer crafts you mentioned were not launched by a Saturn V rocket. Space history lovers notice these things.
The Galileo mission was originally designed to fly directly to Jupiter after being launched from the space shuttle in May 1986. But Challenger happened in January 1986. The VEEGA trajectory was required because as a part of astronaut safety, a less powerful booster was used to launch it out of the shuttle bay.
We didn't not advance in space tech/speed basically nothing from 60-s so nothing new that we would have so much problems with longer space travelling and probably crew will be dead if they will go all the way to Jupiter ,12 years in space without gravity it will be basically self killing
Maybe we will find some new form of elements or compounds in our own solar system planets, which will boost our speed enormously as compared to our fuels.
Yes, indeed humans would be able to reduce time-taken by "Un-manned Orbital Missions" to reach Jupiter, due to day-to-day improvement in space-oriented technology. But it would be impossible for humans to land on Jupiter, being a "Gaseous Planet".
The Galilean moons are the big attraction. Unfortunately, of the four of them, only Callisto is far enough out to not be flooded with radiation and charged particles. Io, Europa and Ganymede are bathed in so much radiation that humans simply could not do EVA without fatal exposure using any kind of shielding we currently possess. Even the spacecraft would need *much* better shielding than ISS has.
Hmm not impossible but i wonder what actually would be required as a radiation shields. Maybe some type of magnetism shield . Who knows . We can make it thick enough with Elon relaunching . It can be made in soave like everything eventually
We would need to transfer our conscience to a robot in order to be able to survive cosmic radiation, and just the sheer boredom is the biggest challenge
I think a manned mission to Jupiter needs to wait until we see how this manned mission to Mars goes first. But even then, going to Jupiter should probably wait until 1. We have faster space flight tech and 2. We're more closely associated with space travel being normal, that way you mitigate the possibility of anxiety overload by creating conditions where prolonged space flight isn't that foreign of an idea. So likely some time passed the 2050's.
And even going to Mars will not happen with the common technology like rockets we use now a days. People like Musk can dream about it, but it doens't change the fact that are bodies are not up to it. Even for a trip to Mars we will need artificial gravity, if we don't want it to be a one way mission. And since no space agencie has even started to design a new way of space transportation, even a voyage for Mars will probably not be before 2050. A trip of 8 months in zero gravity, than a stay on Mars for 8 months in 1/5th of earths gravity, and than a trip back home of 8 months in zero gravity is just not doable for our bodies. This is by now very clear after all the research that has been done on the many astronauts and cosmonauts that have stayed in the divers spacestations for a longer duration. At this monent we onlu know two ways that are possible with our current technology to create artificial gravity. One being a rotating space station that would need to be huge, meaning that it can only be build in orbit which takes many, many, many years and is almost impossible in terms of funding. And a second way would be having a rocket that has non stop propultion in order to create artificial gravity. (Like the idea of a car that does accelerate and you being oushed back.) But sadly our technology fails us, because we have no way of such propultion yet. But Musk his ideas are pure suicide missions, and will therefore never happen. Science knows this and Musk himself probably also. I would of course love it to be different. But for now we can still enjoy the return of humans to the moon somewhere in the upcoming five/ten years. NASA has plans to return with the Artemis program, although this will not be for 2024 as they did plan. It will more likely become 2028. And China would like to reach the moon with their Chang'e mission by 2030. The Chinese plans of building a permanent base on the moon are also quite good and will probably be for 2032. NASA has no defenite plans, or yes it has plans enough but nothing in development yet. Big chance that ESA will work together with NASA on this and that ESA will build the moon base. But this will certainly not happen before 2035. So we still have enough to look forward too, but manned missions to Mars are sadly still very, very, very long away. ✌
@@bryandean1233 I'm sorry, but this just isn't a realistic way of looking at things. Our problems aren't going to be solved by NOT being a spacefaring species. Besides...I fully believe the problems we have are probably Universal. We like to sit here and fantasize about the idea that some Alien race figured out Peace and Prosperity, but I doubt it. No sense in hindering progress for a fairy tale.
I think it's a waste of time and money, Exploring planets and thinking of living on them, You got money to spend, Spend it on Earth our planet. We have exactly what we need here To live and survive.
Some feedback if you read the comments. Can you please also include the metric equivalents when taking about 'miles and pounds' as many of us have no idea of the imperial system. One thing I did learn from this video is that Jupiter has 80 moons! I thought it was only the 4 or 5 we always hear of
@@debbieanne7962 best way to do it is to multiply by 0.45 from lbs to kilos. For example, 10lbs = 4.5kg So 100lbs = 45kg For distance, multiply miles by 1.6. So 1 mile = 1.6km, 2 miles = 3.2km, etc I wish there was more universal education on measurements, but we are lazy in America and don’t like using even number. Lol I mean, 1 foot = 12 inches…. It would be easier working with 10s, but okay. 😂
The best way would be to use the 600 day path and find a way to slow down and orbit the gas giant, without just flying by it. That would save the effort of feeding the crew on their way there and back. The colonization of the Galilean moons will be important in the conquest of Jupiter.
We do not have the technology yet, and we probably won't for a very long time. For the coming decades, it is better to continue to explore our own solar system, and in doing so improve our technology, than to try for an interstellar probe that would literally take thousands of years to reach another star system using the tech we have now.
@@daniels7907 I respect your opinion but compare earth with other planets in our solar system. At night, earths lights shine bright unlike any other planet in our solar system. If there was life, there would be some sort of clear sign in our solar system. That's why I said going in other star systems is more meaningful. We may not have the technology yet, but in a few hundred years, interstellar travel will be much possible.
@@daniels7907 have you heard of breakthrough starshot? Check it out. For now it is obviously more useful to explore our own system because though we still severely lack the means to do so with humans, that could change in the next century. If we can establish a bases on Mars and the Moon much less fuel will be required to launch. We can also be successful in building stations in the atmosphere to launch from. Obviously we are very long way away and if starshot works we could already have probes in the Proxima Centauri system I think in around 20 years from launch
Isadore- our expert Athletes. They always received 250 billion trade of value suite. we changed that, now they get a one time 250 billion suite purchase when they earn their expert sports degree. All of them, that came down, will return to Isadore as suite owners.
We need to get serious about coming up with some new form of interplanator or Interstellar travel because at the rate we're going now we're never even going to make it back to our own damn Moon much less mars or Jupiter or anywhere else. we have to get that speed up that's it. The speeds got to get up
I'm not sure about Jupiter but I know how long it'll take to get to URANUS...lol We just gotta watch out for that black hole ...I know..I know..sorry I just couldn't resist🤭
Whenever we figure out how to get through the firmament and pass the Van Allen radiation belts, then we can ask these types of questions.... silly humans
A fun calculation for the math geeks out there. If we sent a probe at the fastest speed possible today, how long would it take to intercept voyager 1 or 2? Hint. You need to know the current speed of voyager 1 and 2 and the fastest speed we can send out a probe. Have fun.
I believe it depends on the time of the year because Jupiter don’t orbit the sun like earth does. So during that time of the year when earth is closer to Jupiter orbiting the sun will be faster to get there
Maybe in the year 2101. 100 years after the movie 2001: A Space Odyssey. Otherwise, what’s the point of sending humans there if we can do it with robots at a much cheaper price.
Seeing that movie in 1968, it was a world I hoped would exist in 2001, its a world I wanted to live in and still want to live in! Alas, the human race is too petty for it to have become a reality!
Unless we have a mammoth of a breakthrough in speed traveling safely, this will not happen anytime soon. I don't think people truly comprehend how far away these places are. We should stay put for a millennia or two until we can do it right.
@@mm-dw4rr I didn't know my Dad's, dumb, drum, Buick brakes didn't do anything over a 190 Km an hour. (118 MPH) We almost ran over a Beetle as it appeared on the other side of a hill with people inside. Fortunately, we were still going fast enough so we just flew over it. Beep Beep. Mom say's "What's that beeping"? I didn't hear anything? Maybe, the Speedometer is broken.
Okay, here is a question for you: Suppose an interstellar visitor attained solar capture in the vicinity of the Oort cloud, and suppose that these aliens have a precise knowledge of the solar system's planets and know that they must visit the third planet: How long would it take for that interstellar spacecraft to attain orbit around the Earth?
That's actually more a question of how long would it take to slow down, as a ship coming from another star system would be traveling at much higher speeds then what we currently do. I can't do the math myself as it involves calculus, but looking up travel times at 1g acceleration/deceleration it's 11 days from Neptune to earth.
@@lunaticbz3594 for purposes of this thought experiment we must assume that the Interstellar spacecraft is flying at the minimum escape velocity from its sun and that it has slow down to the maximum solar capture velocity of the sun, however it has slowed itself down and when it has done so is excluded from consideration as irrelevant to the question. At the moment of solar orbit insertion what is the minimum length of time for the interstellar spacecraft to attain orbit around the Earth.
@@sentientflower7891 If its flying only at the escape velocity from its own star then its on a journey that will take tens of thousands of years. Even if its coming from our own local neighborhood of stars. If its coming from even halfway across the galaxy we are talking millions of years. If you want to travel between stars you'd want to travel a bit faster then that. We'd never send a manned mission at those speeds, I think its kinda safe to assume no species that values its time in any way ever would either. Even if for whatever reason humanity send a ship like that to Alpha Centuari our closest stellar neighbor. If we launched a single other ship anytime in the next 15K years. That other ship would get there before the first ship did.
The radiation would kill you before you got to the moons of Jupiter. Europa is interesting. No reason to go to Jupiter itself theres nothing to land on or no way to land.
Why it's not possible to go to Jupiter the shorted path possible and then stop the ship to speed 0 once it's near, so that Jupiter catch it with his gravity?
I am from Jupiter and now I'm stuck on this planet dirt I mean earth because my spaceship broke Down I was sent to find intelligent life to recruit to our Jupiter federation
You need massive amounts of rocket fuel to get you there and slow you down upon arrival and then to exit Jupiter’s gravity upon departure. Couple this to having 15 years’ worth of food, water and supplies for a crew of four astronauts, it would make it a nearly impossible mission!
@@DrSlipperyFist Is Grass Legal in Space? Pretty boring out there. I don't think they even allow pets anymore.. Animals have ALREADY died up there! Nice, if you could take your dog for nice Space Walk. Oh well, We always have Sci-Fi 🤨
Jupiter's moon, Callisto, would be perfect for colonization since its not inundated with excess levels of radiation. And the regolith is saturated with water ice on the surface which could be used for the production of water and oxygen. And there appears to be plenty of frozen hydrocarbons and nitrogenous materials on the surface for growing food. Mining the atmosphere of Jupiter for its hydrogen and helium might be a valuable export if done with nuclear powered grazers. In the long run, Callisto's low gravity well should make easier to manufacture orbiting rotating artificial gravity habitats with Earth-like environments within Jupiter space.
