The timescales of this mission are staggering. I've been a space nerd since the early 60s, but, until now, I had never thought in terms of a mission being launced that I might not see the end of. I will be in my 80s by the time JUICE reaches its target, so, for the first time, I'll be watching this rocket taking off wondering if I'll live to see the results...

[@simongeard4824]

Look at projects like Voyager... development started in the early 1960s, and fresh graduates who started with JPL back then were the people running the project by the time the probes arrived at Jupiter in 1979. And by now, some of them could have adult grandchildren who have joined JPL and inherited their grandparent's probes...

If there was a consistently decent cadence of long term missions launching, that would result in a decent cadence of delivery. For that, we need cheaper rockets (coming) and commodity spacecraft that research agencies could just bolt a couple of bespoke instruments to.

It's also a gamble. In the years it takes for the spacecraft to get into position for its mission there are plenty of opportunities for something to go wrong. I'm always happy when something like New Horizons or Cassini gets all the way to its target and nothing major goes wrong.

The mission is longer than 8 years: 8 years to get to Jupiter, then about 4 to do science around Jupiter and its moons. And don't forget the 10+ years already spend planning the mission and building the space craft and instruments. More than 22 years will have passed between selecting the mission (May 2012) and its proposed crash landing (December 2024).

Still it's not a very reliable solution considering that it'll take it some 10 years just to fly to Jupiter. Stuff can impact the arrays on the way there or it can encounter some previously unknown anomaly causing them to be severely degraded before the important part of the mission even starts.

[@ptonpc]

@@_________________404 ESA is pretty good at solar power. The arrays are relatively tough for what they are designed to do and JUICE will be able to run on slightly less power.

I'm used to these gravity assisted missions. I was at CalTech (as a Planetary Society member, not a student) in 1992 for the second Galileo flyby of Earth. But now, I'm starting to wonder if, say, a 100 ton payload + third stage could launch several years from now and still beat JUICE to Jupiter. I know, i know, spacecraft are much more expensive than launches, but i just have the feeling that the "old style" mission plans will soon be history.

[@mancubwwa]

Seriously doubt the 100 ton part(as in 100 ton payload before 2030 with no gravity assists, not that we would naver have this capability). But obviously we are perfectly capable to send a probe to Juputer without gravity assists, in fact we did it already.

[@wally7856]

Beating it to Jupiter is only half the problem, you need to slow it down once it gets there or it'll fly right by.

[@oberonpanopticon]

Nuclear thermal / electric propulsion would probably be more effective than just adding moar boostars. Though I do like to imagine what kind of insane probe mission one could accomplish with a 100+ ton payload margin.

[@mustafahasan957]

Good suggestion !

[@patreekotime4578]

I dont think many of these are strictly "pure" photographs. But I dont think any are strictly digital creations either. Most of them are assembled images of hundreds of actual photographs, animated in 3D and shaded. So if it starts from a photograph, is that "real" or CGI? Or as in the case with false color images based on data sets that dont represent visible light... is it "real" if it isnt true color? Are assembled images still considered photographs? Also, assembled photographs often dont look very good because often the view angles and lighting change between passes... or sometimes camera view angles add distortion, so they HAVE to be digitally processed to look like anything even remotely like a planet. It quickly becomes a very complex and even a political distinction that few people are likely even qualified to take on. But generally, these days if you are looking at "CGI" of Jupiter, it is usually based on real assembled photographs. Compare that with the Star Trek The Next Generation CGI artwork. The planets in that artwork were all created using digital paintings made by artists and then 3D animated. That is pure CGI and you rarely see that anymore, because we have the images, why not use them?

[@paulhaynes8045]

@@patreekotime4578 all good and interesting points, but I still think it would be better to know what we are looking at. It's obviously more interesting and informative to see a video made up of enhanced pictures stitched together and animated - no problem with that - but I'd like to know that's what it is, not just a clever bit of CGI. The problem we have now is that CGI is so good that it's almost indistinguishable from reality (and often 'better') so we're entering a world where you could almost argue that there's no point in sending expensive probes to the planets, when we can already 'see' a much better CGI. I wouldn't argue this, but then again I'm on very thin ice if I can't distinguish between CGI and the real thing! A pertinent example of this at the time of writing is the long awaited first orbital flight of Starship. There are so many excellent CGI renderings of this already around, that the real thing is only going to be recognisable by it's lower quality and the lack of 'impossible' angles (rocket emerging from clouds, taken from above, for example!) - or by something going wrong! As a space nerd, I, of course, want to see the real thing, warts and all. But there are millions (billions?) out there who wouldn't know if the TV company was using a CGI rendering when reporting the launch, because it looks more 'real' than the actual footage. Admittedly (with the rapid development of CGI, AI, etc) this is an existential problem that is only going to get worse and we'll probably just have to live with it. But Scott could do his bit towards clarity by just telling us what we're actually looking at.

[@patreekotime4578]

@@paulhaynes8045 So yall want him to produce his normal videos, and on top of that invent a nomenclature for describing all of the possible variations of manipulated digital images and then research every single image or clip he uses and correctly label it? You realize there a high probability that he likely doesnt know or the attribution is very vague. The current way of attributing images to say "artist's Impression" for anything that isnt strictly a photograph even when the image begins with actual photographs. Because "artists impression" can be anything from a oil painting completely invented in an artists head, to CGI based on real photographs and slightly manipulated (the lightning images come to mind). "Artists impression" doesnt even tell you if its CGI or oil paint, so its kind of pointless. And again, like I said, are false color images real or not? It becomes a rabbit hole and you are asking one random KZbinr to be the arbitor of how that attribution should be done when even NASA is vague on what is a real photograph and what is an assemblage?

I am holding my breath for this! Wow 10 years for a human is a long time but for in galactic terms very short.

[@JBSmoke1]

I am SO looking forward to what JUICE finds!

[@ZachBillings]

Is there a musical sub track in this video? Thought I was hearing a distant train at first but realized it was like a deep chime in the video.

[@unvergebeneid]

It seems fitting that Europe is doing a mission to Europa! I mean, in many European languages such as German or Greek, the two words are homonyms. So the space privé will feel right at home 😄

[@OzzyInSpace]

Officially launching "A Juicer"! lol epic!

[@Bohr2um]

Actually been waiting for this. Searching for life underneath the surface.

[@mk1st]

Hard to imagine colonizing the cosmos. It’s just so far to anywhere.

[@UnshavenStatue]

I thought the background music was a train horn from the yard on the other side of town xD

[@NeonVisual]

Maybe Jupiter is there for when we need fuel to evacuate the solar system.

[@akauppi2]

Very informative! Especially with the oribit animations. Hope your videos are still going in the 30’s so we get good coverage of the results!

[@pierrelemoine8669]

I can't believe he forgot to mention that Gandalf, Frodo, AND Sonic are going to ride on JUICE!

[@elonmax404]

Europe exploring Europa😭😭😭

[@evrydayamerican]

That thing jumps off the platform once those side pieces light lol

[@planetsec9]

I like how JUICE will still be doing gravity assists of Earth in 2029, what a really powerful and mighty rocket with high C3 Ariane 5 is, really great to see planetary exploration using classic 1970's techniques in 2023 thanks to mass fraction constraints, this is definitely the most efficient and sensible way to explore the outer planets....

[@michaeljames5936]

A cool sight would be a ten to twenty kilometre wide asteroid, hitting Europa, or Ganymede. Crunch! splash!

[@michaeljames5936]

Will someone get an AI to make me that as a video, please, please.

[@KawaloliASTP]

Im so excited that the multiple mega mission of europa and ganymed orbiters got an revival with little changes! Icy Moons Explorer and Europa Clipper will be the stars of space probes for Europe and US. That they will work together at the same time, the japanese team onbaord and as children of the legendary galileo and cassini mission. Wow! Good luck for the team and maybe we find another life in the solar system. I can't wait.

[@Admiral_Ellis]

People are talking about all of the science JUICE will gather, but personally I'm excited for what he's going to do for college football.

[@andrewlindberg1887]

Scott.. How can Jupiter’s magnetic field be exploited in some way? Like a long wire stretching out from Io. Or surfing around the system with only a long wire and a power supply using no propellants.

[@emmeXXtreme]

ESA on his way to do a jool 5 mission 🤞

[@witchdoctor6502]

Good news, JUICE is on its way and so far everything is nominal.

[@M_Gargantua]

Critical for important football commentary in a few millennia.

[@perryrush6563]

Thank you to all the internet science nerds who are willing to process the images. From us not so serious science nerds who simply like to bask in the amazingness of the galaxy.

[@jull1234]

Just need to combine it with the New European Water Test On Neptune for the JUICE NEWTON mission.

[@dhoyda]

Here I am thinking that the wait for images from the most recent Mars Rover or from the JWST was a long wait after their respective launches.

[@decibel_tastic2869]

Thank you Scott. Back on point. The motor(s) on Juice firing, again, again, on time on budget, 12 years in !? After passing through radiation, high magnetic fields, micro asteroids.

[@scottmanley]

Rosetta managed over a decade in space just fine. Cassini and Huygens too.

[@aemrt5745]

Voyager II was built with 1970s technology, visited four gas giant planets, and it still operational 43 years after launch. Engineers, we solve problems!

[@Tomcroese]

Ok, I fly safe, and waiting for results!

[@silversurfer66_]

u talked about something i will be dead by

[@snickle1980]

And I'll be at least 12-14 years older than i am now. I'm seeing this comment quite a bit. =/

[@generaldvw]

Something to look forward to😊

[@MartinMizner]

Everytime ESA launches Ariane 5 there's always some cool stuff on board ngl

[@AdjustableSquelch]

quick Q, with most of those type of launches taking years to get the destination through multiple gravity assists, I know bigger boosters cost more money but is it really cheaper to run a smaller booster and run operations/ops rooms for say 3 extra years over the cost of a bigger booster?

[@linecraftman3907]

Big boosters also come with big manufacturing facilities and big launchpads, which are expensive. Also they might not even exist sometimes, when this mission was envisioned and planned, falcon heavy (for example) didn't exist. New Glenn doesnt exist, Vulcan and Superheavy also do not exist (as operational rockets) and SLS is limited to artemis and also very expensive. Additionally Ariane 5 is a reliable rocket and was the choice for JWST for it's amazing track record having 83 consecutive missions without failure between 2003 and 2017 and 1 partial failure in 2017 caused by human error while programming the launch trajetctory.

[@mingtang7052]

That's basic the upper limits a rocket we can get.... Even we have larger rocket, they probably will just put in more stuff instead let it fly faster --- They want use free planet energies (actually a lot of energy), and they think more obit time might be useless since they already get all the data they want. Ariane 5 get a very powerful upper stage, it's performances is very close to the most powerful upper stage engine we have (RL-10). And since it's a EU satellite, they do want use EU rocket. When we talk about deepspace mission, the good upper stage is more important than LEO deliver capabilities. (For example Falcon heavy vs. Vulcan to LEO can carry 2.3 times stuff, but to GTO, drop down to 1.75 times --- Why I say upper stage is important!)

[@linecraftman3907]

@@mingtang7052 Crazy how Nuclear thermal rockets could have been built 50 years ago, which could have easily flung lander missions even to moons of outer planets as their efficiency is double the hydrolox engines like RL-10. And I'm not even going into weeds of other exotic propulsion technology. (From goofy project Orion to more reasonable magnetoplasmodynamic thrusters)

[@patreekotime4578]

There are entire years between even the flyby boosts. I doubt they will run full mission command the entire time until they reach Jupiter space. A computer can monitor it's progress and just record the data most of the time. Not sure that really costs anything in the grand scheme.

[@Jason-gq8fo]

I can’t wait till we have starship and we can make bigger cheaper probes that don’t have to do so many long gravity assists to get there

[@PopeGoliath]

Why are the outer wrappings on space probes wrinkly? I would assume, with the precision these craft are built, that even a very fine film could be applied more evenly? Thermal expansion can't possibly so pronounced it needs that extra material, can it?

[@TheEvilmooseofdoom]

It's usually mylar insulation and in a place with no air there is no need to be neat.

[@scottmanley]

The insulation is made of thin layers, if the layers touch then the insulation doesn't work as well. Turns out the lightest way to do this is to let it wrinkle.

[@Martinit0]

@@scottmanley I am now imagining that Airbus and likely also Thales employ somebody specializing in proper wrinkling of space mylar sheets.
