A space mission with a name like no other is about to embark on a journey to find alien life on the moons of Jupiter.
Juice (that’s short for Jupiter Icy Moons Explorer) is a European Space Agency (ESA) venture to make unprecedentedly detailed observations of the gas giant.
It will include searching its icy moons – Ganymede, Callisto, and Europa, which each have their own oceans – to find out whether they could have supported life, and maybe if they still do.
As the final countdown to launch approaches, here’s everything you need to know about humanity’s latest quest to explore the stars.

When and where is the launch?
Juice is planned to launch at 1.15pm UK time on Thursday.
It will be fired skyward aboard an Ariane 5 rocket from the ESA’s spaceport in Kourou, French Guiana.
So yes, it’s not actually launching from Europe, but rather a French territory on the north coast of South America.
A livestream of the launch will begin around half an hour before the blast-off time, so you can get swept up in the excitement before the real action begins.

If the timings go to plan, Juice will separate from the upper stage of Ariane 5 at 1.42pm UK time, and should send its first signal down to the Earth’s surface by 1.51pm, allowing mission crews to take control of the craft.

How long will the mission go on for?
Quite some time, you certainly won’t be tuning in for a livestream of the entire mission.
Juice’s total cruise time will be eight years and include flybys of Earth and Venus on its way to Jupiter, where it will make close encounters with its three moons.
They will be observed using remote sensing and geophysical tools, as well as equipment on the craft.
Jupiter itself will also be closely examined, with astronomers hoping that knowledge gained about its complex magnetic, radiation, and plasma environment will help inform studies of other gas giants.
One of which is Saturn, another gas giant with moons boasting oceans that could support life. Such worlds have the greatest known reserves of water outside Earth, and Juice is the first mission to explore them.
The ESA will be assisted in its work by NASA, and the space agencies of Japan and Israel.

Why are we still racing to space?
What do we know about the spacecraft and rocket?
Every space launch is something of an engineering miracle, but Ariane 5 is relatively standard so far as rockets go.
Described by the ESA as “the workhorse” of its access to space, it’s not to the level of NASA’s record-breaking, multibillion-dollar Space Launch System powering the Artemis programme.
The ESA has launched more than 100 Ariane 5 rockets, and it will finally be retired next year. You can probably guess what its successor is called.

Juice is pretty much top of the line so far as probes go – and it cost £1.4bn.
Much of that went towards making sure solar power can work in a section of space that enjoys just 3% of the illumination Earth gets from the sun. Earth is about 93 million miles from the sun, Jupiter isn’t far off 500 million.
It is, as Juice spacecraft manager Christian Erd described it…
‘A faraway, dark place’
The Juice mission’s intrepid team of engineers were tasked with developing capable solar cells that could operate in super dark conditions.
The result were ones with a “triple junction” design – that means three layers of cells are placed on top of each other, generating power from different wavelengths of sunlight.
It makes them more efficient than those made for previous missions, but the task at hand was still a tough one.

Solar cell engineer Carsten Baur said the solar power received around Jupiter was “like going indoors” compared to what you would get near Earth.
Speaking of going indoors, Juice needs to be covered in so many solar cells (24,000) that there are enough to fill an average-sized living room.
It’s due to arrive at Jupiter by 2030, beating Juice by a year thanks to taking a shorter route.

Juice will end its mission by going into orbit around Ganymede, marking the first time a spacecraft has ever been stationed at a moon other than Earth’s. It’s expected to happen in 2034.
Indeed, this spacecraft will be making history for a long time to come.
Israel is committing genocide in Gaza, according to a commission established by the United Nations.
The report claims “it is clear that there is an intent to destroy the Palestinians in Gaza” and says Israel’s actions meet the criteria set down for defining a genocide.
It is the first time that such an explosive allegation has been made publicly by a UN body, and is likely to be greeted with fury by the Israeli government.
Israel‘s Foreign Ministry said it “categorically rejects this distorted and false report” and called for the commission to be abolished.
“Three individuals serving as Hamas proxies, notorious for their openly antisemitic positions – and whose horrific statements about Jews have been condemned worldwide – released today another fake ‘report’ about Gaza,” it said in a statement.
“The report relies entirely on Hamas falsehoods, laundered and repeated by others. These fabrications have already been thoroughly debunked.”

The accusation of genocide is made by the UN Independent International Commission of Inquiry on the Occupied Palestinian Territory.

The commission, which has been studying the conduct of Israel since the Hamas attacks of 7 October 2023, has concluded that Israel has committed four of the five acts laid out in the Genocide Convention.
It alleges Israel has been killing Palestinians or forcing them to live in inhumane conditions that led to death; causing serious bodily or mental harm, including through torture, displacement and sexual crime; deliberately imposing inhumane conditions, and fourthly, imposing measures intending to prevent births.
This final claim is linked to an attack on the Al-Basma IVF clinic, which the commission claims destroyed around 4,000 embryos and a further 1,000 sperm samples.
The report claims Israel has “flagrantly” ignored “numerous warnings” over the humanitarian crisis in Gaza and has set out to “destroy the healthcare system in Gaza”.
It also alleges that Israeli military personnel have carried out sexual and gender-based violence, including “rape and sexualised torture”, as part of “a pattern of collective punishment”, and accuses Israeli forces of deliberately targeting some children “with the intention to kill them”.

Although other UN bodies and personnel have previously linked Israel’s actions with allegations of genocide, this is the first time that any UN body has claimed to have made a definitive judgment.
“The responsibility for these atrocity crimes lies with the Israeli authorities at the highest echelons,” said Navi Pillay, the chair of the commission.
Within the report, it concludes that “Israeli President Isaac Herzog, Prime Minister Benjamin Netanyahu and then Defence Minister Yoav Gallant, have incited the commission of genocide”.
Nearly 65,000 people are now believed to have died, according to figures collated by Gaza’s health ministry. It does not distinguish between civilians and combatants in its count.
The commission claims that a majority of these are women, children and elderly people.
The commission says it is now looking at further evidence against other individuals accused of inciting genocide.

Last year, the International Criminal Court (ICC) issued arrest warrants against both Mr Netanyahu and Mr Gallant for allegedly committing the war crime of using starvation as a method of warfare and also for war crimes during the Gaza conflict.
Mr Netanyahu described the warrants as “antisemitic”, while a sense of outrage echoed across much of the political spectrum in Israel.
Then US President Joe Biden called the warrants “outrageous”; his successor, Donald Trump, issued an executive order to introduce sanctions against personnel from the ICC, while inviting Netanyahu to the White House.
It is hard to believe that either Israel or the US will be any more accepting of this report. Israel has long claimed that the UN is biased against it and is more liable to criticise Israel than any other nation.

The US, which offered a rare, if mild, rebuke to Mr Netanyahu after he launched an attack on Hamas officials in Qatar last week, has since sent Secretary of State Marco Rubio to Jerusalem as a sign of solidarity.
The commission has asked for nations to stop supplying Israel with weapons and says states have a “legal obligation” to do everything within their power “to stop the genocide in Gaza”.
It also calls on Israel to immediately allow “unhindered” access for internationally recognised aid agencies, including the UN.

Does the UK think there’s a genocide in Gaza?
It wants the Gaza Humanitarian Foundation (GHF), set up earlier this year by Israel with American help, in order to distribute aid, to be shut down.
Hundreds of people have been killed around GHF sites, while a separate UN-backed body has said that parts of Gaza have been designated as suffering from famine.
Israel denies this – a senior military leader told me that “it is a pure, total lie – there is enough food for everyone”. It claims that the UN relied on faulty data and Hamas propaganda.
This latest UN report is likely to be met with similar claims.
Earlier this month, the International Association of Genocide Scholars passed a resolution stating that Israel’s conduct passed the threshold of committing genocide.
However, a report from the British government said it had “not concluded” that Israel intended to “destroy in whole or in part a national, ethnic, racial or religious group”.
Volodymyr Zelenskyy has called for a “clear position” from Donald Trump to stop Vladimir Putin and end the war in Ukraine.
In an exclusive interview with Sky News’ lead world presenter Yalda Hakim, the Ukrainian president said the only way for the fighting to stop was for defined security guarantees to first be put in place.
And that, he said, could only come if Mr Trump was bold.
He told Sky News he hopes UK Prime Minister Sir Keir Starmerwould drill into the detail of securing Ukraine’s future with the president during his state visit to Britain this week.
He said: “I very much hope he (Starmer) will be able to have a very specific discussion on the security guarantees of the US for Ukraine.
“Before we end the war, I really want to have all the agreements in place. I want to… have a document that is supported by the US and all European partners. This is very important.
“To make this happen, we need a clear position of President Trump.”

“I believe that the US is strong enough to take decisions of their own,” he said. “I believe Donald Trump can give us air defence systems in quantity and US has enough.
“I’m sure the US can apply enough sanctions in order to hurt the Russian economy, plus Donald Trump has enough force to make Putin afraid of him.
“Europe has already introduced 18 sanctions packages against Russia. And all that’s lacking now is a strong sanctions package from the US.”
As news broke that British fighter jets were flying air defence missions over Poland after a Russian drone incursion, Hakim asked the Ukrainian leader what message he thought Putin was sending to Europeans.
“He’s testing NATO,” he said. “He wants to see what NATO is ready for, what they’re capable of, both diplomatically and politically, and how the local population will respond to this.”
“Also, in my opinion, the other message they are sending is, ‘don’t you dare to give Ukraine additional air defence systems, because you might need them yourself.'”
Bristling with frustration – Zelenskyy’s message is clear
Ukraine’s president has a very clear message for Trump – you alone have the power to stop Putin, and the time to act is now.
Meeting with me in Kyiv on the eve of the US president’s state visit to Britain, Zelenskyy bristled with frustration at the failure of the Western powers to ramp up pressure on the Kremlin, even as the Russians escalated their attacks on Ukraine.
Asked if the summit between Trump and Putin in Alaska has proven a mistake, he responded without hesitation that Putin is clearly not paying a price for his actions.
Zelenskyy believes Trump is reluctant to put pressure on Putin because it might jeopardise attempts to end the war.
But the Ukrainian leader argues this isn’t the way to handle the Russian president.
Zelenskyy also argued Trump’s emphasis on getting the Europeans to ratchet up economic pressure – foremost by stopping their purchases of Russian energy and tariffing other buyers like China and India – was understandable, but that the world’s sole superpower shouldn’t wait for others to act.
Trump has called on EU countries to end all Russian oil and gas purchases – and only then will he consider imposing sanctions on Russia.
He and First Lady Melania will stay at Windsor Castle and be treated to a flypast by the Red Arrows as well as UK and US F-35 military jets on the east lawn, and a special Beating Retreat military ceremony.
They will also visit Chequers, the prime minister’s official country residence in Buckinghamshire, though details of what they will discuss – and whether it will include the situation in Ukraine – have not been revealed.

“He should have received a setback in this war and stop. Instead, he received de-isolation,” he said.
“He definitely wants to trick the US. He is doing everything he can to avoid sanctions, to prevent the US and Trump from putting sanctions on him.”

But the Ukrainian leader argues this isn’t the way to handle the Russian president: “He understands force. That’s his language. That’s the language he understands. He doesn’t speak many languages, but that’s the language of force he understands – just like Russian, you know, his mother tongue.”
