NASA has launched a mission to a rare asteroid covered in metal that is two billion miles (3.6bn km) and six years’ travel time away from Earth.

Scientists hope exploring the Psyche asteroid will help them understand more about how Earth formed and what makes it habitable.

Lead scientist Lindy Elkins-Tanton, of Arizona State University, said: “It’s long been humans’ dream to go to the metal core of our Earth. I mean, ask [author] Jules Verne.

“The pressure is too high. The temperature is too high. The technology is impossible. But there’s one way in our solar system that we can look at a metal core and that is by going to this asteroid.”

Most asteroids tend to be rocky or icy, and this is the first look at a metal one – the team is also hoping to take the first-ever images of it.

Potato-shaped rock is 150 miles wide

Psyche, which may be the battered remains of a planetesimal, or a building block of a rocky planet, is the largest of the nine metal-rich asteroids discovered so far, NASA said.

The potato-shaped rock measures about 144 miles by 173 miles (232km by 280 km) at its widest and has a mass of about 440 billion pounds.

It will dwarf the van-sized spacecraft, with solar panels big enough to fill a tennis court.

Also called Psyche, the spacecraft was launched on a SpaceX Falcon Heavy rocket from NASA’s Kennedy Space Centre, in Florida, on Friday.

The agency believes the asteroid, which orbits the sun between Mars and Jupiter, is brimming with iron, nickel and other metals – and quite possibly silicates. It is a dull grey colour, probably because its surface is covered with fine metal grains from cosmic impacts.

Metal cliffs and lava flows

It was discovered in 1852 and named after Greek mythology’s captivating goddess of the soul.

As to what they will find, scientists imagine spiky craters, huge metal cliffs and metal-encrusted eroded lava flows that are greenish-yellow from sulfur. However, Ms Elkins-Tanton admitted that is “almost certain to be completely wrong”.

Tiny amounts of gold, silver, platinum or iridium – iron-loving elements – could be dissolved in the asteroid’s iron and nickel, she said.

“There’s a very good chance that it’s going to be outside of our imaginings, and that is my fondest hope.”

Believed to be a planetary building block from the solar system’s formation 4.5 billion years ago, the asteroid can help answer fundamental questions such as how life began on Earth and what makes our planet habitable, according to Ms Elkins-Tanton.

Led by Arizona State University on NASA’s behalf, the $1.2 billion (£985m) mission will swoop past Mars for a gravity boost in 2026.

Three years later, it will reach the asteroid and attempt to go into orbit around it, circling it at a distance of between 47 and 440 miles (75 and 700 km) until at least 2031.

Why Putin has suddenly offered an ‘Easter truce’ in Ukraine – and the interesting way it’s being presented

Why Putin has suddenly offered an 'Easter truce' in Ukraine - and the interesting way it's being presented

Well it is something, but it’s by no means everything – a ceasefire for 30 hours, not 30 days.

This feels like a diplomatic dance, rather than a military, or moral, manoeuvre.

An Easter truce – announced by Vladimir Putin on Saturday – is significant in the sense that, if it holds, it’ll be the first actual cessation of hostilities since the war began.

And it’s significant in the sense that it’s the first actual concession made by Moscow since Donald Trump initiated peace negotiations two months ago.

But – and there’s always a “but” when it comes to the Kremlin – how much of a concession is it really? And how much difference will it make militarily?

It’s nowhere near what the White House has been asking for, and it’s nowhere near what Ukraine has previously consented to.

The American president’s first proposal was a full 30-day ceasefire. Kyiv agreed but Moscow didn’t, not without conditions.

Then there was the attempted maritime truce. Again, Moscow’s agreement came with strings attached, in the form of sanctions relief, so it never got off the ground.

So why suddenly suggest a truce now?

America had made no secret of its growing frustration at the lack of progress in peace negotiations.

Trump threatened to “take a pass” on attempts to reach an agreement on Friday after his secretary of state said the US might “walk away”.

I don’t think that in itself would be a problem for Russia, given its military dominance. But I think it could be a problem if Trump blames Putin for the lack of progress, and then pulls the plug on their thaw in relations as well.

So this feels like Putin is giving Trump just enough to keep him on side, without actually making any major concession.

And the way it’s being presented is interesting too – at Russia’s initiative, on humanitarian grounds, Ukraine must “follow our example”.

He’s trying to cast himself as the peacemaker in the eyes of the US president – as the one who give solutions, not problems – which appears contrary to Trump’s opinion of Volodymyr Zelenskyy.

More than 90 Palestinians killed by Israeli strikes in 48 hours, says Gaza health ministry

More than 90 Palestinians killed by Israeli strikes in 48 hours, says Gaza health ministry

Israeli strikes in Gaza have killed more than 90 people in the past 48 hours, the Hamas-run health ministry in the territory has said.

Women and children were among 15 people who were killed overnight on Friday in the southern city of Khan Younis, according to hospital staff.

At least 11 of those who were killed were sheltering in a tent in the designated humanitarian zone of al Mawasi, where hundreds of thousands of displaced people are living, the hospital workers said.

A further four people were killed in separate strikes on the city of Rafah, including a mother and her daughter, according to Gaza’s European Hospital, where the bodies were taken.

Israel – which has not commented publicly on the latest strikes – has vowed to intensify attacks across Gaza and occupy large “security zones” inside the area.

It says this is to put pressure on Hamas to release more hostages and ultimately agree to disarm and leave the territory.

For weeks, Israeli troops have also blockaded Gaza, barring the entry of food and other goods.

Last month, 15 aid workers were killed and buried in a shallow grave after being fired upon by Israeli troops.

Hamas is currently holding 59 hostages, 24 of whom are believed to be alive.

The group says it will only return them in exchange for the release of more Palestinian prisoners, a full Israeli withdrawal from Gaza and a lasting truce, as called for in the now-defunct ceasefire agreement reached earlier this year.

Hamas’s armed wing said the fate of Israeli-American hostage Edan Alexander was unknown after a guard who was holding him was found killed.

On Tuesday, Hamas said it had lost contact with a group of militants holding Mr Alexander in Gaza.

Earlier this week, the United Nations warned that almost all of Gaza’s population of more than two million people is relying on the one million prepared meals produced daily by charity kitchens.

The only other way to get food in Gaza is from markets, but rising prices make them unaffordable for most, according to the World Food Programme. The UN humanitarian office, known as OCHA, called it Gaza’s “worst humanitarian crisis” since the escalation of hostilities in October 2023.

Dr Hanan Balkhy, head of the World Health Organisation’s eastern Mediterranean office, urged the new US ambassador in Israel, Mike Huckabee, to push Israel to lift Gaza’s blockade so medicines and other aid can enter the strip.

“I would wish for him to go in and see the situation first hand,” she said on Friday.

In his first appearance as ambassador, Mr Huckabee visited the Western Wall, the holiest Jewish prayer site in Jerusalem’s Old City. He inserted a prayer into the wall, which he said was handwritten by US President Donald Trump.

Mr Huckabee said every effort was being made to bring home the remaining Israeli hostages.

Hamas-led militants attacked southern Israel on 7 October 2023, killing about 1,200 people and abducting 251.

Israel’s offensive has since killed more than 51,000 Palestinians, according to Gaza’s Hamas-run health ministry, which does not distinguish between civilians and combatants.

British couple killed in Naples cable car crash named

Two Britons killed in a cable car crash near Naples have been named by Italian media.

Graeme Derek Winn, 65, and his wife Margaret Elaine Winn, 58, were among four people – including an Israeli woman and an Italian man, the cable car operator – who died in the incident on Thursday, which officials said happened after the cable snapped.

The only survivor, a second Israeli tourist, was in a stable but critical condition, the Naples hospital treating him said on Friday.

Ms Winn was initially named by Italian media as Margaret Elaine Winn, but it is understood she was known as Elaine.

The couple were described as “good friends” by Chris Mann, who posted on social media saying they were “enjoying retirement with lots of motorbike tours and holidays”.

“How incredibly sad,” he wrote in a Facebook post on Saturday.

A Foreign, Commonwealth & Development Office (FCDO) spokesperson said: “We are supporting the families of a British couple who have died in Italy and are in touch with the local authorities.”

Nine passengers were helped out of a separate cable car that was stuck mid-air near the foot of the mountain following the incident.

They were freed one by one in a difficult operation using harnesses, footage on RAI television and other media showed.

Italy’s alpine rescue, along with firefighters, police and civil protection services, responded to the incident.

It occurred just a week after the cable car, popular for its views of Mount Vesuvius and the Bay of Naples, reopened for the season. It averages around 110,000 visitors each year.

Umberto De Gregorio, chairman of the EAV public transport company that runs the Mount Faito cable car, described the incident as “a tragedy” and said the service would remain shut “for a long time” following the crash.

He told Sky News the cause of the incident was being investigated, and that before its reopening, the cable car service had undergone three months of tests with checks carried out every morning.

“Everything we had to do was done,” he said.

“Evidently something went wrong, we don’t know what, whether an exceptional unforeseen event or human error. The investigators will discover all this.”

He added: “Furthermore, I knew very well one of the four victims, our employee. He is the brother of my driver – who is also my friend, since we lived together practically every day.

“I knew him and yesterday I saw his heartbroken wife, we hugged each other. There is so much emotion.”

The UK Foreign Office said: “We are dealing with an incident in Italy and are in contact with the local authorities. Our thoughts are with those affected.”

Italian Prime Minister Giorgia Meloni expressed her condolences for the victims and their families and said she was in touch with rescuers. She spoke from Washington, where she was meeting US President Donald Trump.
