A NASA spacecraft has launched from Florida on a mission to find out if Jupiter’s icy moon Europa could support life.
The craft, called Europa Clipper, was on a SpaceX Falcon Heavy rocket which blasted off from Kennedy Space Center at Cape Canaveral under sunny skies.
Its launch had been delayed for several days by the deadly Hurricane Milton that struck the US state last week.
The mission’s main scientific goal is to establish whether there are places below the surface of the moon that can harbour life.

Scientists are interested in the salty liquid water ocean, 40-100 miles deep, that previous observations have shown is under Europa’s thick 10-15 mile icy shell. And where there is water, there could be life.
The robotic solar-powered spacecraft, which is carrying nine scientific instruments, will travel 1.8 billion miles in a trip lasting about five and a half years and is due to enter orbit around Jupiter in 2030.
Dozens of flybys planned

It will carry out 49 close flybys of Europa over three years, gathering detailed measurements to investigate the moon.
The probe, which is about as large as a basketball court, will fly as low as 16 miles above the surface, soaring over a different location during each flyby to scan nearly the entire moon.

It will not look for life but will focus on the ingredients necessary to sustain life – searching for organic compounds and other clues as it uses radar to peer beneath the ice for suitable conditions.

How big is the craft?
Europa Clipper, which is around 30m long and 17m wide with its antennas and solar panels – and weighs nearly six tonnes – is the largest spacecraft NASA has ever built for a planetary mission.
Its solar panels will gather sunlight for powering scientific instruments, electronics and its other subsystems in the £3.9bn mission.
The moon has been viewed as a potential habitat for life beyond Earth in our solar system.

Main objectives
NASA said: “The mission’s three main science objectives are to understand the nature of the ice shell and the ocean beneath it, along with the moon’s composition and geology.”
“The mission’s detailed exploration of Europa will help scientists better understand the astrobiological potential for habitable worlds beyond our planet,” the space agency added.
The mission’s deputy project scientist Bonnie Buratti said: “There is very strong evidence that the ingredients for life exist on Europa. But we have to go there to find out.”
The planetary scientist, from NASA’s Jet Propulsion Laboratory, added: “Just to emphasise: we’re not a life-detection mission. We’re just looking for the conditions for life.”
Anti-Trump protests took place across America on Saturday, with demonstrators decrying the administration’s immigration crackdown and mass firings at government agencies.
Events ranged from small local marches to a rally in front of the White House and a demonstration at a Massachusetts commemoration of the start of the Revolutionary War 250 years ago.
Thomas Bassford, 80, was at the battle reenactment with his two grandsons, as well as his partner and daughter.
He said: “This is a very perilous time in America for liberty. I wanted the boys to learn about the origins of this country and that sometimes we have to fight for freedom.”
At events across the country, people carried banners with slogans including “Trump fascist regime must go now!”, “No fear, no hate, no ICE in our state,” and “Fight fiercely, Harvard, fight,” referencing the university’s recent refusal to hand over much of its control to the government.
Some signs name-checked Kilmar Abrego Garcia, a Salvadorian citizen living in Maryland, who the Justice Department admits was mistakenly deported to his home country.
People waved US flags, some of them held upside down to signal distress. In San Francisco, hundreds of people spelt out “Impeach & Remove” on a beach, also with an inverted US flag.
People walked through downtown Anchorage in Alaska with handmade signs listing reasons why they were demonstrating, including one that read: “No sign is BIG enough to list ALL of the reasons I’m here!”

Protests also took place outside Tesla car dealerships against the role Elon Musk ahas played in downsizing the federal government as de facto head of the Department of Government Efficiency (DOGE).
The protests come just two weeks after similar nationwide demonstrations.

Organisers are opposing what they call Mr Trump’s civil rights violations and constitutional violations, including efforts to deport scores of immigrants and to scale back the federal government by firing thousands of government workers and effectively shuttering entire agencies.
The Trump administration, among other things, has moved to shutter Social Security Administration field offices, cut funding for government health programs and scale back protections for transgender people.
US vice president JD Vance has met with Pope Francis.
The “quick and private” meeting took place at the Pope’s residence, Casa Santa Marta, in Vatican City, sources told Sky News.
The meeting came amid tensions between the Vatican and the Trump administration over the US president’s crackdown on migrants and cuts to international aid.
No further details have been released on the meeting between the vice president and the Pope, who has been recovering following weeks in hospital with double pneumonia.
Mr Vance, who is in Rome with his family, also met with the Vatican’s number two, Cardinal Pietro Parolin, and the foreign minister, Archbishop Paul Gallagher.
The Vatican said there had been “an exchange of opinions” over international conflicts, migrants and prisoners.
According to a statement, the two sides had “cordial talks” and the Vatican expressed satisfaction with the Trump administration’s commitment to protecting freedom of religion and conscience.
“There was an exchange of opinions on the international situation, especially regarding countries affected by war, political tensions and difficult humanitarian situations, with particular attention to migrants, refugees and prisoners,” the statement said.
Francis has previously called the Trump administration’s deportation plans a “disgrace”.
Mr Vance, who became Catholic in 2019, has cited medieval-era Catholic teaching to justify the immigration crackdown.
The pope rebutted the theological concept Mr Vance used to defend the crackdown in an unusual open letter to the US Catholic bishops about the Trump administration in February, and called Mr Trump’s plan a “major crisis” for the US.
“What is built on the basis of force, and not on the truth about the equal dignity of every human being, begins badly and will end badly,” the Pope said in the letter.
Mr Vance has acknowledged Francis’s criticism but said he would continue to defend his views. During an appearance in late February at the National Catholic Prayer Breakfast in Washington, he did not address the issue specifically but called himself a “baby Catholic” and acknowledged there were “things about the faith that I don’t know”.
While he had criticised Francis on social media in the past, recently he has posted prayers for the pontiff’s recovery.
