THE EUROPEAN SPACE Agency’s Juice craft will return to Earth tonight, taking part in a world first fly-by.
A team of three researchers from the Dublin Institute for Advanced Studies (DIAS) will play a key role in the first ever attempt to fly a spacecraft past the Moon, and then past Earth.
Flight controllers from Esa will guide the Jupiter Icy Moons Explorer (Juice) past the Moon and then Earth.
The risky manoeuvre will take Juice on a shortcut to Jupiter via Venus, using the Moon’s gravity, and then Earth’s, as a natural brake – slowing itself down and then sling-shotting on to the next phase of its journey.
The mission launched in April 2023 on a 4.1 billion-mile journey which will take more than eight years and aims to investigate whether Jupiter’s three moons – Callisto, Europa and Ganymede – can support life.
Onboard are 10 scientific instruments, which will investigate whether the gas giant’s three moons – Callisto, Europa and Ganymede – can support life in its oceans.
Today from around 11.57pm into the early hours of Tuesday, Esa says a double world first will take place with the lunar-Earth fly-by and the double gravity assist manoeuvre.
The move will change Juice’s speed and direction to alter its course through space.
However, the slightest mistake could take the spacecraft off course and mean the end of the mission.
Commenting on DIAS’s role in the flyby, Professor Caitriona Jackman, head of the planetary magnetospheres research group at DIAS, said, “We will be monitoring the flyby with trepidation as it’s an extremely challenging undertaking – the slightest mistake could take Juice off course and spell the end of the mission.
“This is the first step in Juice’s journey through the solar system on its way to Jupiter. The spacecraft will use the gravity of the Moon and then Earth to bend its path through space and redirect it on course for a flyby of Venus in August 2025.
“This will help to ensure it arrives at Jupiter with the right speed and direction. It’s a journey that requires perfect accuracy and in-depth planning.”

Our fearless traveller is getting a nudge from the Moon and Earth next week, in the first of four flybys that will put Juice on precisely the right path to arrive at Jupiter in July 2031.

Jackman said that having the opportunity to test ideas about the spacecraft’s behaviour in the environment of a moon “is truly exciting and will be a huge boost in confidence for our research once Juice arrives at Jupiter”.
“The encounter of Earth’s moon is a practice-run for when we get to Jupiter, where we will study moons with underground oceans that might support life. I’m extremely proud of the work carried out by our research group so far, and that we can be part of such an important mission.”
Earth will bend Juice’s trajectory through space, redirecting it on course for a fly-by of Venus in August 2025.
From then on, the energy boosts will begin, with the spacecraft being sped up by Venus and then twice by Earth – the space exploration equivalent of drinking three back-to-back espressos.
The risky manoeuvres are needed because Jupiter is on average 800 million kilometres from Earth.
Without an enormous rocket, sending Juice straight to the gas giant would require an impossible 60,000kg of onboard propellant.
It would also need to carry a huge amount of additional propellant to slow itself down enough to go into orbit around Jupiter once it arrives, rather than simply zipping straight past and off into outer space.
The complex and constantly evolving route has been carefully planned out by the mission analysis team over the last 20 years.
Some keen stargazers may be able to spot Juice pass overhead, with the spacecraft flying directly over south-east Asia and the Pacific Ocean.
Powerful binoculars or a telescope will give them the best chance of seeing the spacecraft.
Two cameras on board Juice will be taking photos throughout the lunar-Earth flyby, which will be shared publicly as they are received on Earth.

Boo hoo .. God love the poor mites . Maybe we should give them free sweets and drinks and molly coddle them just a wee bit more to get them through this horrific time in school .. Think of the Children
@BL Music: I’m going say or hope you don’t have kids…
@BL Music: you obviously are not a parent. Or you had a tough time in school and think kids have it easy in school when not all of them do . Not every child is cut out for school I had to move my son from a primary school because he was being bullied. ..by his teacher so unless you know better cop on
@Karen Marten: 3 kids .. I was generalising .
I do realise school is tough for some and it’s not for everyone. Most kids are ok with it though
@Clare Power: I bet you don’t have a sense of humour
@BL Music: oh its funny now. Is it after you’ve been called out…I see pet..
@BL Music:
@BL Music: I feel sorry for them when was the last time u actually asked them are they OK or have you left that job to their mother
@BL Music: well then why be such an a ss and post that comment
@BL Music: having a sense of humour what’s so funny about kids feeling isolated and bullies at school so badly that they taking their own lives and not just teenagers primary school students . Because school do nothing to quash bullying or bullies .
@BL Music: There is a big difference between snow flake kids and kids being bullied. today bullying is constant, with social media kids can’t get away from it, different years ago when you left it in school and got some resbite from it. No wonder so many kids suffer with anxiety.
But responsibilities lies with head teachers, and staff, as I heard of many victim blaming saying the kids are to sensitive.
That’s not an excuse.
They have a duty of care and should be zero tolerance of bullying. Both sets of parents should have to engage is solving the issues
@BL Music: one third are not. That’s one third to many.
@Karen Marten: sounds like your kid is a spoilt brat, I’d say the school was delighted to be rid of the runt
I have a niece that was relentlessly bullied in school by a group of girls, she had to change schools as while the teachers etc tried to help, it was the parents of the little darlings that cudnt accept they were bullies…..
@Clare Power: Just like the dogs, it’s always the owners.
@Clare Power: perhaps your niece is the problem
Everyone is different. For some people school years are the best for them. They love the academic routine and it’s structure, rules and way of life and that’s perfectly fine. For others it is just pure torture, some people need some years in the real world working with their hands to experience for themselves or see the managerial jobs they might like and then decide to go and study for the qualifications at 23 instead when are more determined and focused. Nothing wrong with that. I hated school and went back to college in my 30′s. Have my technical and academic qualification now and have my own house, wife and kids and doing fine in life. Not liking geography biology and history at 17 doesn’t mean your life is over. The teachers themselves could do with explaining that to more students.
The comments from some of the people on here makes me hope that they don’t have kids. I’d say if this poll was run when I was at school in the 80s the percentage of people saying they don’t belong there would be even higher. People forget what it feels like to be a kid and they try to rationalise it with their now adult minds. But being a child can be scary and if you don’t understand that please stay away from kids.
@Gearoid MacEachaidh: “Back in the day” some of us were glad to make it past the bicycle shed unharmed on the way home. That was terrifying but made you socially smart and run damn fast.
Can’t see this happening nowadays, no wonder some kids don’t know how to toughen themselves up, something parents should be concerned with.
@Athena: it may have
“toughened” you up. But how many kids take their own lives due to bullying, whether it by by fellow students or abusive teachers in the past? Is your response to that “oh well they weren’t tough enough” ? Have some compassion. Not everyone is like you.
@Gearoid MacEachaidh: Indeed, not everyone is like me. I was bullied for wearing glasses and being in the unfortunate situation of being a teacher’s kid at the school. Got it from both sides, some kids as well as the teachers. So what? Toughening up is the only way to face it, a great lesson for later in life
Kids now can switch off bullying.
Don’t use your socials.
Do Karate or Taekwondo for building self esteem and if someone comes after you, you hit them where it hurts most. Go in first and go in hard. Go in smart and cover your back, especially when going in against your teachers or other parents who would punish you over a lost tennis match against your dad.
Has served me well but it doesn’t mean you trade that in for empathy or compassion.
God help them if they were sent down the mines as they would’ve been in the past, they wouldn’t be long saying they miss school
@qffaffaf affrafrfraf: you forgot to say back in my day…
@Clare Power: What does it matter, the Sloth master is right though.
@Athena: Our stoned friend isn’t really that convincing and is basically saying that if children could experience the sloth ‘interpretation’ of reality (which is actually just a massive assumption) they would be ‘different’… I’m not convinced by this hypothetical truth tbh.
@qffaffaf affrafrfraf: what a stu did small.man.you are
@Thesaltyurchin: I grew up in a mining town where non academically inclined boys went to the mines about 2,700 feet underground from age 16, that was life as we knew it. Have a funny suspicion that those non belonging kids (who probably focus too much on the emotional side of life rather than embracing the rational one) wouldn’t do too well down in them shafts either.
It’s not like the workers were collected by buses for the various shift starts either, nor were the steel cookers.
@Athena: Probs only live til they were 35 or something. Maybe this third of school goers (tho stats don’t do it for me) feel like they don’t belong because class sizes are huge and a lot of schools are under-provided for where space and time are concerned, When I was at school there was 18–25 in a class (it was the second biggest national school in the country at the time) it’s double that now and any of my local schools are exactly the same with zero infrastructural investment in some 30 years. (we Irish only like to build for others, much like the mining!). Anyway this is all the guesswork of some keyboard crusader’s
What a load of self-indulgent nonsense
@Joseph Lenihan: that’s right Joseph..a good thrashing is what they need..like in you’re day…didn’t do you any harm did it lol
@Joseph Lenihan: addressing bullying is self indulgent? I’m hoping you just jumped to the comments after reading the headline and don’t genuinely believe bullying isn’t worth dealing with.
@Joseph Lenihan:
Nobody “belongs” in a school. It is a presage for the wider world. They need to be helped to cope with it as they will have to cope with the big bad world later on.
@Padraig O’Brien: Plenty of people manage to get on just fine in the big bad world with all its different personalities and characters and still feel a sense of belonging be it at home, with friends, in education or in work. Being out in the big bad world doesn’t preclude someone from feeling confident wherever they are and have the ability to get on with most people, and deal with the ones who are determined not to get on with anyone. No good reason a child should feel isolated in school.
@Padraig O’Brien: It’s very easy to see how institutions like the Magdalene Laundries survived for so long in Ireland with attitudes like this. “Shur it’s just they way things are, they’ll have to get used it.”
If a third of students feel this way then maybe the school system isn’t functioning very well and needs to be improved and it’s not all those students fault for a lack of “cope”, is that such a radical thought?
Ok so my experience with both primary and secondary schools . Primary schools are not teaching kids properly . Was just discussing this with my kids . My 11 year old has the same monotonous home work every day for years English work book and maths. She’s exempt from irish . No proper maths homework like what we did in school .no history no geography except for one or two projects . We had infirmary school history geography maths English and irish home work most days. And spelling sand tables and no They are not setting kids up for secondary school they haven’t a clue what to expect stuck in subjects they know nothing about for 3 years then loaded with home work they never experienced before . So I understand where these kids are coming from .
@Karen Marten: And yet children today perform far higher on pisa tests than any other generation before, they perform much better in the leaving (which hasn’t changed) and they perform better in college than any other Irish generation. The countries that still do primary they way you want it done, perform much worse than our kids on independent tests. That is a fact.
We enjoy abusing and dismantling our services, why would Education be any different.
Even reading the text what happens outside the school happens outside the school makes me angry. Yes of course if it didnt happen in the school yard the school isnt going to be driving the bus on dealing with it but the school has a unique opportunity as a neutral body to teach children how to treat each other. Part of the issue is the shrug of the shoulders by the educators. Many also feel their kid is “winning” if they get away with it but the child loosing the most is the one that is not corrected and shown how to behave… long term, time after time, the are the one who ends up loosing out. Lets teach our kids to be nice, to the best of their ability, to include each other, to help each other and to just simply not be mean. My eldest is only 8 and I could already write a short story on exclusion, bullying and being mean. In my experience in Primary school this is driven from home. I can not imagine these children in Secondary.
Some of the nonsense being spewed in the comments on an article focused on the bullying of children is astounding. Some people are shameless.
@Sun Rise: their childless or their wife’s raise the kids while they sit in the pub…..if you were a half decent parent, you would understand the struggles a lot of kids face in school
Bullies thrive in an environment where they can’t be punished. We have made our school system such an environment and bullies sre thriving.
Maybe it’s all the woke stuff going on….
@N.F. Court: or maybe its people who use wokism as an excuse to bully others.maybe if schools were inclusive, and kids were excepted, all would be better in the world.
@N.F. Court: What are you on about? All the evidence says that schools with well implemented inclusion policies have less bullying, happier children and better academic performance.
People seem to want there kids to go to college which is fair enough I get that. But not every child is suited to the academic life. Most kids are more practical. Lots of money to be made in the trades. Nothing wrong with making money with physical hard work
@Michael o Dwyer: oops their. Just for the linguists
Really poor headline. Misrepresents the statistic by not including “or don’t feel they can express themselves “
@Eric O’Flynn: Six of one…you don’t need to be the same as everyone else to feel like you belong amongst a set of people. I feel a sense of belonging amongst my family, my friends, my little team in work, we’re all quite different people with different personalities and interests but I still ‘fit in’.
@Megan Ward: no it’s 2 different things. Not fitting in is one. No being able to express yourself is another. Saying one third is the former is simply not factual. I’m not disputing that either is happening or of concern. I’m just saying the headline is inaccurate.
Hard to express yourself when you are crammed into a small room with 30 other people.
Kids too soft now adays mams and dads babying them too much . I was quiet and sensitive when younger especially but had to toughen up
Well the futures looking bright living in mammy and daddy’s for many long years ahead regardless of how many hours worked. Let them enjoy whatever times there is in school and you g ages because once they hit 21 on great times ahead thanks to ff,fg and cabbage head. Save up and emigrate for a future best of luck to them we have failed them and made a normal life next to impossible now.
have your say
