GO JUICE!!!
The orbital mechanics alone are astounding!
Much respect and admiration for the team for putting the child's drawing on the rocket fairing. that is awesome and a dream come true for the child.
Yeah, I love the artwork too!
@@LaunchPadAstronomy 1:03 do you mean “Europa” instead of “Jupiter”?
@@Gagafos5962 err...yes.
That was awesome, thanks for that very informative video.
8 years to wait, huh? 8 long years ... feels like the New Horizons mission all over again. Hope I'm still kicking around when JUICE finally arrives. Go, ESA!
Whoa! That's exactly what I was gonna comment! Call me crazy but I want to live to see life found on one of the icy moons before I depart.
it will last longer though as active science gathering mission.
Not as active spacecraft though.
Time goes fast. I remember Bepicolombo mission launching to Mercury, like it was yesterday. Back then I thought, oh so many years to wait, and now, we're just two years from Mercury orbit insertion.
CHRISTIAN!!!! This was awesome!!! Going to these moons and doing this type of science will hopefully answer some great questions. This is very exciting!!!
Another winner here. Now all I have to do is to live long enough !
Thanks Once again, real astronomy, and a fantastic interview, that even dopes like me can appreciate .
I'm so geeked out by this and can't wait to see JUICE and the Europa Clipper mission working in tandem!! Good luck today ESA!!
Fantastic interview! Especially the explanations of instrumentation. There isn’t anywhere near enough of that available for exploration spacecraft. Go JUICE!
very exciting to research these moons up close. 8 years! 2031 arrival. cannot wait!
This is incentive to stay healthy so I can see the results of these awesome missions! Thanks for another update Christian!
Thanks for sharing your knowledge and thoughts, very interesting and appreciated.
What a mission for the books and the future, I just hope I am alive when Juice arrives. Go ESA and Go LPA.
Great Video and Interview :) Looking forward to JUICE and Clipper
Just beautiful program! ❤
gonna be chuggin that JUICE let’s gooooooOOOOOO
Looking forward to be watching this later tonight.
Super excited!
Thanks man, I was just wondering how JUICE was getting on and if its nearly ready for launch only yesterday, this is the second time you've answered my wonderings without me needing to ask! I hope they find a lazy river to cross.
Go JUICE! I’m really excited
I haven't heard about Jupiter's radiation environment before. Maybe a video describing this is in order?
Great video and interview with very interesting details.
Hi Christian! This was a great interview. Excited for the launch and years ahead. Would love to learn more about Jupiters radiation environment. In a future video possibly?
Thanks Geetanjali, that’s a great suggestion!
Fascinating. Great interview!!
Than you. Glad you enjoyed it!
yayayayay juice!!!!!!!! yay!!!!!!!!! i
The audio seems not to be synched up with the video during the portions where you are talking to the camera. Other than that, very informative video!
That was awesome. Fingers crossed for the mission and here’s hoping Juice and the Europa Clipper get close, but not too close. We don’t want a fender bender in space!
No, no, thank you and thank Olivier and thank the artist who drew the faring stickers!
I'm excited for JUICE too...
Crackin programme. Really enjoyed this one. Pity about the delayed launch but better late than never.
Some good news though is that evidently the 1 day delay does not preclude a lunar flyby, so it looks like we're gonna get the double flyby next year!
It's great that the interplanetary transport network of low Δv trajectories allows us to get beefier payloads further out, but the years spent getting to the destination is a real bummer. Ariane's inability to relight the upper stage dooms us to an extra, what, 2.5 years of transit?
Official rescheduled time for launch is now set for April 14th 14:14 CEST
This mission is going to be very JUICY!!!
I see what you did there.
@@LaunchPadAstronomy The launch is scheduled for 2.15 PM 13 April, European Central time (US EST is 6 hours earlier) and will be carried by youtube channel ESA Web TV. Just saying.

I did not understand why the probes will have to finally impact either a moon or Jupiter itself. Dr. Witasse said "for planetary protection". What is it that has to be protected by an impact?
It’s a little bit confusing because historically we avoided accidentally crashing into moons in an effort to not interfere with any life that might exist or might someday exist on them. But in this case, JUICE won’t be able to break out of Ganymede’s orbit so to mitigate against accidental contamination they will bring it down at a pre determined location on Ganymede. Better than an uncontrolled deorbit.
Very good video,
However I think the data gained from the passes by Calisto would be very useful because of it's potential to also host life while also having radiation levels close to those on earth.
There was little mentioned about Calisto.
You may have gathered from the above that I am a dreamer who who believes that human exploration of the moon's of Jupiter and more is possible in the future, if we make it happen.
Let us go fishing ! Thank you humanity.
Why Jupiter that has been explored in high details already, while Uranus and Neptune remain mainly unknown.
Jupiter is easier and much quicker to reach, and more 'sexier' target than Uranus and Neptune. Neptune was, basically for decades, expected to be target of a Cassini-type Nasa flagship mission, but nothing came out of it. More recently Uranus orbiter was put forward by NSF as a key flagship mission - along with Enceladus orbiter and lander - for Nasa in the 2030s, but nothing seems to come out of that. The Uranus orbiter would have to launch 2031 or 2032, but no money has been forthcoming. A Triton flyby mission, Trident, lost to DAVINCI+ and VERITAS in the latest Nasa Discovery mission selection, but neither of those Venus missions might fly now, and Trident would have likely shared their fate.China has plans for small Uranus flyby mission, but that might as well never leave the drawing board.
A jupiter probe can be solar powered(only 4% of earth level). A probe around saturn or farther away needs nuclear energy source. Esa has no easy access to a nuclear energy source.
@@kalzium8857 Despite France being the most nuclearized country in the world?
@@courcheval i am not a nuclear engineer, so i can't answer this question in great detail. In the cold war the usa had an ambitious nuclear program. After the cold war the usa downsized the production of these nuclear isotopes like plutonium, but had still reserves left for space probes. France has not that much nuclear material left for space probes. I mean look at the number of nukes from each country (usa vs any other country aside from the usa). I mean even nasa uses solar power for the juno probe.
The moons haven't. We want to know for sure if there are ocean worlds and the composition of the oceans. Those are the most likely places to have life. Proximity. The only moon in the solar system that has it's own magnetosphere (Ganymede). Set the stage for future missions to explore the oceans.
Amazing.
Such a long time to wait though. 😢
I would imagine the oceans on Ganymede to contain massive waves, given the surface formations. It will be interesting to see how Jupiter's and other moons affect the tidal balance also.
I also hope it can detect life? If there's movement within the oceans that is. Although I suspect it would have to be a massive entity to trigger any kind of readings?
My brain is working overtime with the endless possibilities of discoveries to come.
I am super excited for this.
Once again, thank you for your most excellent videos.
And thank you Oliver for your time and specialist input..
It can't really detect life, but definetly habitability for potential life and there will likely be followup missions that will go looking for life itself in the future.
Detecting life is still decades away. We aren't close to that. Maybe in 10 years with more advanced missions you can get your hopes up but until then you're setting yourself up for disappointment.
The juice is loose!
Except this time the ride is a bit fancier than a white Bronco
Go juice 😊
So exciting..;. I just wish it wasn't an 8 year wait for the science. =(
I'd love some Ganymede juice. Wow JUICE's last gravity assist by Earth in 2029 then only a little over 2 years to Jupiter incredible.
I'm not sure what you mean by 2 years to Jupiter, but it is actually 8 years to Jupiter ( Juice was launched on a rocket just a couple days ago) because as the scientist said it is a massive instrument so several gravity assists will be used to get it to Jupiter using the least amount of fuel.
@@michaeldeierhoi4096 It's last gravity assist is from Earth in 2029 so from Earth gravity assist in 2029 to Jupiter in 2031 so 2 years 8 years total yes, but only 2 years for last leg from Earth to Jupiter make sense?
@@spencerthompson1049 I haven't looked at the details that closely, but you've either got that 2 year figure wrong or I don't know what. But this is a perfectly legit probe heading to Jupiter to explore three of its moons.
@@michaeldeierhoi4096 8 years total for JUICE to get to Jupiter arriving 2031, in that time it will gain a lot of speed from gravity assists it's last gravity assist in the year 2029 it will use earth then in only a little over 2 years it will reach Jupiter in 2031 I don't know how else to explain it to you I'm just saying it's pretty incredible the speed it gains from those gravity assists in that last 2 years on it's way to Jupiter it will travel from Earth to Jupiter.
Such an awesome piece of hardware, powered by light not nuclear and 6 tons damn!
The solarpanels are huge and ESA has already experience with the Rosetta probe.
JUICE launch rescheduled to tomorrow morning 9:15 CEST due to adverse meteo conditions (high risk of lightning).
Ugh. That means no lunar flyby next year. Rats, but better safe than sorry.
@@LaunchPadAstronomy Definitely. It would be no good to have a probe running around with maybe half of its electronics fried by a lightning strike. In this scenario, the Ariane body *should* act as a Faraday cage, but... yes, better safe than sorry :(
Life in Europa's ocean might be similar to earths life forms that exist around hyperthermal vents in earth's ocean. life with out sun light.
Saw the thumbnail and thought O.J. Simpson must have gone into space......in a white Bronco.🙃
I’m surprised a mission hasn’t been proposed where a shuttle doesn’t offload numerous rovers onto different moons.😮
That would need a far larger launch rocket and a larger mission craft. Much more mass to shift at lift off, and more fuel required.
Also, there wouldn’t be enough fuel on board to manoeuvre from one moon orbit to another once in orbit around Europa or Jupiter.
Another mission to Ganymede and Io perhaps?
But these all cost, and there are too many space deniers calling to defund NASA, as they have been convinced by devious internet trolls that we can’t get into space and never have.
8 years? 😲😱 But….I’ll be old by then 😢. Hope it makes it through the asteroid belt.
It will make through the asteroid belt. The asteroid belt is WAY more sparsely habited by asteroids than sci-fi likes to think. The real worry is launch which, like for airplanes with take-off and landing, is the most dangerous part of the journey
It puts some perspective on the size of space and how long it takes to traverse it with our current technology.
3RD?!?!?!?================>YESSSSSSS!!!
JIME
I hope i will be free on my income when the juice arrive Jupiter
Why will Juice make an impact on Ganymede while Cassini made a dive into the atmosphere of Saturn to prevent biological contamination of any of the moons of Saturn?
One article says they think Ganymede is unlikely to support life because of an ice floor to the ocean instead of rock. They will also get to collect data from the impact.
Ideally, the spacecraft would be disposed of by impacting Jupiter. That's what they did with Galileo and what they'll do with Juno. However, JUICE will end its mission while in orbit around Ganymede and won't have the delta-v to break orbit and impact Jupiter, so it will have to be deorbited to impact Ganymede. Not ideal but better than leaving it there, I guess.
In the Chinese mythological zodiac, Jupiter moves through 1 different zodiac sign roughly each year (because 1 Jovian year is almost 12 Earth years). This most likely inspired the yearly change of the Zodiacs in the Far East (Year of the Rat, Ox, Tiger etc.) Similarly, Galileo seeing the 4 moons of Jupiter is the first ever clear evidence that "Not everything revolves around the Earth", dealing Geocentrism its first irrefutable major blow. Similarly, Jupiter is largely responsible for the creation of Earth the way it is (size, distance from the Sun) and the current state of the Solar System if the Grand Tack hypothesis is to be believed. All planets except Mercury orbits the Sun close to Jupiter's ecliptic plane, rather than the Sun's own equator.
This planet literally and poetically has influenced humanity more than any other objects in the Solar System except maybe the Sun and Moon.
From an astrological point of view, it is a very favorable time when the sun is in conjunction with Jupiter, and furthermore in the sign of the zodiac sign Aries, which stands for new beginnings and a pioneering spirit.
At the start of the probe at 2:15 p.m. in Kourou, the Sun and Jupiter are in conjunction even in the ninth house, which is ruled by the zodiac sign Sagittarius, whose ruler is Jupiter!
Furthermore the 9th house, how appropriate, stands for travel, broadening horizons and expansion!
Meanwhile, the Moon and Pluto are conjunct Capricorn (Moon) and Aquarius (Pluto) in the 6th house at 2:15 p.m. This means the emotional need (Moon) to work obsessively hard (Pluto) every day (6th house).
Could mean the mission requires a lot of hard work consistently over a long period of time.
So let's all stay tuned :)
At the time that it reached Jupiter GTA 6 still hasn't come out
Something's up with MIRI again dammit.
Nice Steal Your Face! 💀☠️💜
What a Long Strange Trip it's Been!
It’s in every one of my videos. NFA!
@@LaunchPadAstronomy is that a cover from a Boxes Set?
@@Shivaho It's actually the Grateful Dead Scrapbook. I got it for my mom many years ago and I keep it on my set as a tribute to her. Also, because I'm a Deadhead.

MTG heard the anagram Juice and thought wizard space Jews with lasers 😂😂😂😂
If we don't include Planet Earth, 😅, then in my opinion Jupiter is the most important planet in our solar system. Why? Because it has everything. It has every mineral, gas and liquid man knows about. It also has many moons and the most valuable ones.
Jupiter is at the boundary of the inner and outer solar system. It's a perfect mid course to anything and everything else. I predict it's the most logical place for mankind other than Earth.
I have for decades predicted that Man will create large orbiting industries and habitations in orbit around Jupiter and on its moons. Frankly, if humanity can't take careful, kind advantage of Jupiter we'll never leave our solar system. Jupiter is our salvation and future. Mars is only our first step off Earth and past the moon. Mars is an easier place to go to and leave from. But after Mars only Jupiter is important. Mars has to be done in order to practice and design for Jupiter. Mars basic value is a stepping point to Jupiter.
Has anyone noticed the logical way our solar system is laid out and the interesting progression of material needs, distance, forces, etc. To me it looks like a training exercise course. It doesn't seem random or even natural or standard in system comparisons. I see a different pattern laid out intentionally for a purpose. I surely never believed in coincidences or luck either.
What a waste of time shutting down the whole world for covid.
Couldn't agree more. Millions of people drifted to poverty and the delay of many projects will be noticeable even in years. Huge waste.
All that time lost in fly-byes just to get enough speed to get to Jupiter. Fortunate that is a temporary pain and will end soon. Better engines are coming. Eventually about the end of this century man's first space elevator will be available. That means we can build objects in orbit without launching them into orbit first. Very large objects could then be built and released from orbit to other destinations with much better propulsion. Means we can forget fly-byes, save time on journeys. Future modules can follow and build onto the previous ones. Thus a space station spinning with artificial gravity around Mars and Jupiter.
orange juice is better
Jeez, twin egg heads. 😂😂😂
I resemble that remark :)
@@LaunchPadAstronomy Well, that was my first reaction seeing you both. 😆😂. My second was having eggs for breakfast. Sunny side up? It was a very interesting interview and I'm not easy to please on interviews.
It isn´t an interesting trajectory. It is an undersized launcher!
It is most definitely an interesting trajectory necessary because of the 3000 kg mass. JUICE will use four planets including the earth twice to get to Jupiter. Also the second rendezvous with earth includes the Moon which has never been done before. The delay in the launch added over a year to the arrival but it is what it is.
1) Write captions for the person you interviewed. His heavy accent is hard to understand. So hard in fact that the automatic subtitles were layed😢 in with errors (ladden but this onion example of how bad auto subtitles functioned)
2) the ads are numerous and far too long. First ad break is 4 minutes long (2 ads of 2 min each). Then there are THREE more ad breaks- all with DOUBLE ads
Thank you for the feedback. It's weird that you were given automatic subtitles because I disabled those and added an English transcription of my own. I'm guessing that you were using English subtitles?
