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.

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.
The IDF has admitted to mistakenly identifying a convoy of aid workers as a threat – following the emergence of a video which proved their ambulances were clearly marked when Israeli troops opened fire on them.
The bodies of 15 aid workers – including eight medics working for the Palestine Red Crescent Society (PRCS) – were found in a “mass grave” after the incident, according to the head of the UN Office for Coordination of Humanitarian Affairs Jonathan Whittall.
The Israeli military originally claimed an investigation found the vehicles did not have any headlights or emergency signals and were therefore targeted as they looked “suspicious”.
But video footage obtained by the PRCS, and verified by Sky News, showed the ambulances and a fire vehicle clearly marked with flashing red lights.
In a briefing from the IDF, they said the ambulances arrived in the Tel Sultan neighbourhood in Rafah shortly after a Hamas police vehicle drove through.

An IDF surveillance aircraft was watching the movement of the ambulances and notified troops on the ground. The IDF said it will not be releasing that footage.
When the ambulances arrived, the soldiers opened fire, thinking the medics were a threat, according to the IDF.
The soldiers were surprised by the convoy stopping on the road and several people getting out quickly and running, the IDF claimed, adding the soldiers were unaware the suspects were in fact unarmed medics.
An Israeli military official would not say how far away troops were when they fired on the vehicles.
The IDF acknowledged that its statement claiming that the ambulances had their lights off was incorrect, and was based on the testimony from the soldiers in the incident.
The newly emerged video footage showed that the ambulances were clearly identifiable and had their lights on, the IDF said.
The IDF added that there will be a re-investigation to look into this discrepancy.

Addressing the fact the aid workers’ bodies were buried in a mass grave, the IDF said in its briefing this is an approved and regular practice to prevent wild dogs and other animals from eating the corpses.
The IDF could not explain why the ambulances were also buried.
The IDF said six of the 15 people killed were linked to Hamas, but revealed no detail to support the claim.

Bodies of aid workers found in Gaza
The newly emerged footage of the incident was discovered on a phone belonging to one of the workers who was killed, PRCS president Dr Younis Al Khatib said.
“His phone was found with his body and he recorded the whole event,” he said. “His last words before being shot, ‘Forgive me, mom. I just wanted to help people. I wanted to save lives’.”
Sky News used an aftermath video and satellite imagery to verify the location and timing of the newly emerged footage of the incident.

Aid worker attacks increasing
It was filmed on 23 March north of Rafah and shows a convoy of marked ambulances and a fire-fighting vehicle travelling south along a road towards the city centre. All the vehicles visible in the convoy have their flashing lights on.
The footage was filmed early in the morning, with a satellite image seen by Sky News taken at 9.48am local time on the same day showing a group of vehicles bunched together off the road.
Ukrainian President Volodymyr Zelenskyy has hit out at the US over its “weak” response to lethal Russian attacks on his hometown on Friday.
President Zelenskyy posted a lengthy and emotional statement on X about Russia’s strikes on Kryvyi Rih, which killed 19 people.
Meanwhile Ukrainian drones hit an explosives factory in Russia’s Samara region in an overnight strike, a member of Ukraine’s SBU security service told Reuters.
In his post, President Zelenskyy accused the United States of being “afraid” to name-check Russia in its comment on the attack.
“Unfortunately, the reaction of the American Embassy is unpleasantly surprising: such a strong country, such a strong people – and such a weak reaction,” he wrote on X.
“They are even afraid to say the word “Russian” when talking about the missile that killed children.”
America’s ambassador to Ukraine Bridget Brink had written on X: “Horrified that tonight a ballistic missile struck near a playground and restaurant in Kryvyi Rih.
“More than 50 people injured and 16 killed, including 6 children. This is why the war must end.”

Strike on Zelenskyy’s home city
President Zelenskyy went on in his post to say: “Yes, the war must end. But in order to end it, we must not be afraid to call a spade a spade.
“We must not be afraid to put pressure on the only one who continues this war and ignores all the world’s proposals to end it. We must put pressure on Russia, which chooses to kill children instead of a ceasefire.”
Grandmother ‘burned to death in her home’
Oleksandr Vilkul, head of the city’s defense council, said the missile attack, followed by a drone attack, had killed 19 people, including nine children.
“The Iskander-M missile strike with cluster munitions at the children’s playground in the residential area, to make the shrapnel fly further apart, killed 18 people.
“One grandmother was burnt to death in her house after Shahed’s direct hit.”
Russia’s defence ministry said it had struck a military gathering in a restaurant – an assertion rebutted by the Ukrainian military as misinformation.
“The missile hit right on the street – around ordinary houses, a playground, shops, a restaurant,” President Zelenskyy wrote.
Mr Zelenskyy also detailed the child victims of the attack including “Konstantin, who will be 16 forever” and “Arina, who will also be 7 forever”.
The UK’s chief of the defence staff Sir Tony Radakin said he had met the Ukrainian leader on Friday, along with French armed forces leader General Thierry Burkhard.
“Britain and France are coming together & Europe is stepping up in a way that is real & substantial, with 200 planners from 30 nations working to strengthen Ukraine’s long term security,” Sir Tony wrote.
Global financial markets gave a clear vote of no-confidence in President Trump’s economic policy.
The damage it will do is obvious: costs for companies will rise, hitting their earnings.
The consequences will ripple throughout the global economy, with economists now raising their expectations for a recession, not only in the US, but across the world.
