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.
Jeff Bezos’s Blue Origin is set for the inaugural launch of its new space rocket on Monday in a development that could add more fuel to the billionaire space race.
The New Glenn rocket is due to blast off from Cape Canaveral – the result of a multi-billion dollar, decade-long effort that could set the stage for Amazon’s satellite constellation venture and dent Elon Musk’s market share.
Mr Musk’s SpaceX has dominated the scene for many years but both Mr Bezos and Virgin Galactic founder Sir Richard Branson have designs on outer space… and the wealth tied up in its exploration.
Jeff Bezos and Blue Origin
“Ever since I was five years old, I’ve dreamed of traveling to space,” Mr Bezos said ahead of his journey to the edge of space in 2021.
He founded the Blue Origin venture with the aim of having “millions of people working and living in space”.
For years it has launched – and landed – its reusable New Shepard rocket to and from the brim of Earth’s atmosphere, but has never sent anything into orbit. That could all change on Monday.
Blue Origin will be hoping its New Glenn rocket will be able to compete with SpaceX’s Falcon 9, the world’s most active rocket.
Compared to Mr Musk’s Falcon 9, the New Glenn is about twice as powerful and its payload bay diameter is two times larger in order to fit bigger batches of satellites.
The upcoming launch is also a key certification flight required by the US Space Force before New Glenn can launch national security payloads as part of multi-billion dollar government tenders Blue Origin hopes to win.
Elon Musk and SpaceX
“I want to die on Mars – just not on impact,” Elon Musk once quipped.
The Donald Trump ally, who is frequently pictured wearing an “Occupy Mars” shirt, has enjoyed relative dominance of the private space industry through his company SpaceX.
Back in 2016, Mr Musk outlined his vision of building a colony on Mars “in our lifetimes” – with the first rocket propelling humans to the Red Planet by 2025, though this deadline does not appear likely to be met.
For many years the company used an image of the Martian surface being terraformed (turned Earth-like) in its promotional material. However, a NASA-sponsored study published in 2018 dismissed these plans as impossible with the technology available then.
SpaceX missions have included both US government contracts and launching the company’s Starlink satellite internet network.
And while Mr Bezos’ New Glenn rocket is much more powerful than the successful Falcon 9, SpaceX’s next-generation Starship, a fully reusable rocket system currently in development, would be more powerful still.
Mr Musk sees Starship as crucial to expanding Starlink’s footprint in orbit. Its next test flight is expected later this month and will involve deploying mock satellites.
Also seeking a stake in the upper atmosphere is Virgin founder Sir Richard, whose Virgin Galactic effort took its first tourists to the edge of space in 2023.
The crew took the passengers about 55 miles (88km) above Earth where they experienced zero gravity during the flight which lasted just over an hour.
“My mum taught me to never give up and to reach for the stars,” the British billionaire once said.
The company is currently taking a pause from flights as it develops new space vehicles, Forbes reported in October last year.
Its new fleet of Delta vehicles are scheduled to resume commercial spaceflight by 2026.
On 19 December, 80-year-old Palestinian grandmother Halima Abu Leil was shot in an Israel Defence Forces (IDF) raid on her neighbourhood in Balata refugee camp in Nablus, West Bank.
Two days later, Halima’s children told Sky News their mother was shot six times by Israeli special forces on her way to buy groceries. She died soon after.
Warning this piece includes an image from CCTV of the moment Halima Abu Leil was shot.
“They could see she is an elderly lady but they shot her six times – in her leg, in her chest. When she was first shot in her legs, she knelt on the ground,” her daughter said.
Newly released grainy CCTV footage shows the moment she was shot and reveals that a van marked as an ambulance was used during the surprise IDF raid.
Halima Abu Leil’s family want the footage to be seen.
Sky News’ Data & Forensics unit has analysed the CCTV and geolocated the street where the video was filmed. It is the exact location Halima’s son told us she “fell to her knees” as she was shot.
Three men are also walking down the street. There is no visible contact between them and Halima. Based on our analysis of their silhouettes, the figure in the middle appears to be holding a weapon. They are likely to be neighbourhood militants.
The three men veer to the right, moving into a sunny area. One takes a seat on some stairs, while the other two stand. They join someone sitting there already.
A few yards away, Halima stops in the middle of the street to speak to another woman with a shopping trolley.
An ambulance pulls into vision, separating the two women, and drives slowly down the street. A white van pulls in behind the medical vehicle.
A few moments later, the passenger door of the white van opens and a faint cloud of smoke is visible, suggesting that a gunshot is fired.
This is the moment Halima falls to her knees.
The men, some of them armed, scatter to the right and left into alleyways along with other people in the street.
A detailed analysis of the footage suggests that visible clouds of smoke on the walls are the result of multiple shots. The footage and imagery we gathered from the site of the killing shows bullet holes in the building next to where Halima was standing.
The woman she was speaking to moments earlier takes cover in a doorway.
At the same time, figures who appear to be Israeli military forces exit the ambulance in the foreground. They are equipped with helmets, backpacks, rifles, and other gear.
Armed figures can also be seen leaving the white van in the background. They are seen aiming their weapons down the street.
Halima appears to get hit again and collapses to the floor. The men likely to be neighbourhood militants are not visibly present in the street when this happens.
At the time of our previous report, the IDF said they had conducted “counterterrorism activity” in Balata camp the morning Halima was killed.
We approached the IDF about the CCTV footage and the use of a medical vehicle to conduct their operation.
This was its response: “The IDF is committed to and operates in accordance with international law. The mentioned incident is under review. The review will examine the use of the vehicle shown in the video and the claims of harm to uninvolved individuals during the exchange of fire between the terrorists and our forces.”
The use of a marked medical vehicle for a security operation could be a contravention of the Geneva Convention and a war crime – as well as Halima’s killing.
The United Nations Special Rapporteur on occupied Palestinian territory Francesca Albanese watched the CCTV video and told Sky News she was shocked but not surprised.
She says: “When I look at the footage, what emerges prima facie is that there were no precautions taken – within these operations whose legality is debatable – to avoid or spare civilian life. No principle of proportionality because there was wildfire directed at the identified target and ultimately no respect for the principle of distinction.
“So this was a murder in cold blood and could be a war crime as an extrajudicial killing.”
According to the United Nations Office of Human Rights in occupied Palestinian territory (OHCHR oPt), Israeli security forces and settlers have killed at least 813 mostly unarmed Palestinians, including 15 women and 177 children, since 7 October 2023.
In a statement to Sky News regarding Halima’s killing, the OHCHR oPT said: “Any deliberate killing by Israeli security forces of Palestinians in the Occupied West Bank who do not pose an imminent threat to life is unlawful under international human rights law and a war crime in the context of Israel’s occupation of the Palestinian Territory.
“This incident must be investigated independently, effectively, thoroughly, and transparently. If there is evidence of violations of the applicable law enforcement standards, those responsible must be held to account.”

Donald Trump’s Middle East envoy has met Israel’s prime minister in an effort to secure a ceasefire deal in Gaza before the president-elect takes office on 20 January.
Benjamin Netanyahu’s office confirmed details of the meeting with Steve Witkoff on Saturday, adding that the head of the Israeli Mossad intelligence agency has been deployed to Qatar in order to “advance” talks.
It was not immediately clear when David Barnea would travel to Doha for the latest round of indirect discussions between Israel and Hamas.
Earlier on Saturday, an Israeli official said some progress had been made, mediated by Egypt, Qatar and the United States, to reach a deal in Gaza.
The mediators are making renewed efforts to halt fighting in Gaza and free the remaining Israeli hostages held there before Mr Trump takes office.
A deal would also involve the release of some Palestinian prisoners held in Israeli jails.
Families of Israeli hostages welcomed Mr Netanyahu’s decision to dispatch the officials, with the Hostages and Missing Families Forum Headquarters describing it as a “historic opportunity”.
Mr Witkoff arrived in Doha on Friday and met the Qatari Prime Minister Sheikh Mohammed bin Abdulrahman Al Thani, Qatar’s foreign ministry said.
Egyptian and Qatari mediators received reassurances from Mr Witkoff that the US would continue to work towards a fair deal to end the war soon, Egyptian security sources said, though no further details were released.
Israel launched its assault on Gaza after Hamas fighters stormed across its borders in October 2023, killing 1,200 people and taking more than 250 hostages, according to Israeli figures.
Families of the roughly 100 hostages still held in Gaza are pressing Mr Netanyahu to reach a deal to bring their loved ones home.
Since then, more than 46,000 people have been killed in Gaza, according to Palestinian health officials, with much of the area destroyed and gripped by a humanitarian crisis, with most of its population displaced.
