The European Space Agency (ESA) has successfully launched Hera, its first planetary defence mission designed to assess whether future asteroids can be deflected from a collision course with Earth.
The probe, which is about the size of a small car, is on its way to a pair of asteroids 195 million kilometres away from Earth, one of which NASA deliberately crashed a spacecraft into two years ago.
It is ESA’s part of a collaboration with NASA to develop future technologies to protect the Earth from a catastrophic asteroid impact.
“The risk of an asteroid hitting our planet affects everyone everywhere, making planetary defence an inherently international endeavour,” said Josef Aschbacher, director general of ESA.
In September 2022, NASA’s DART mission deliberately crashed into the 151m-wide asteroid Dimorphos.
Its goal was to see if smashing a vending machine-sized space probe into an asteroid could nudge it enough to deflect it from a direct hit with Earth.
Dimorphos is a moon of a larger asteroid, Didymos – the binary asteroid chosen as a target.
It was thought the smaller asteroid would remain in its parent’s gravitational pull, eliminating the risk of a future collision with Earth even if the prang with DART proved unpredictable.

Observations of the DART impact revealed it shifted Dimorphos’s orbit around Didymos by around 32 minutes – 26 times greater than the minimum deflection predicted by NASA scientists.

Hera is designed to provide a detailed post-match analysis of the DART-Dimorphos encounter so it can be developed into a strategy for planetary defence.
As well as studying Dimorphos and Didymos in detail using 11 on-board instruments, it will deploy two micro-satellites that will go into orbit around the asteroid system.
Their missions will end with the two probes landing on Dimorphos’s rubble-like surface, hopefully providing new details about its composition.
“Hera will gather the data we need to turn kinetic impact into a well understood and repeatable technique on which all of us may rely on one day,” said Mr Aschbacher.

While most of us think of civilisation-ending asteroid impacts as the stuff of Hollywood movies, they remain a genuine, albeit low, risk.
Over our 4.5 billion year history, Earth has suffered more than three million impacts from various bits of space rock.
Perhaps the most famous was the impact 66 million years ago of a 180km-wide asteroid in what is now Chicxulub, Mexico.
The resulting planetary-scale extinction event helped consign dinosaurs to the natural history books.

Things have now quietened down a bit, but just last week an asteroid missed Earth by about one million kilometres – less than three times the distance to the Moon – very close by astronomical standards.
Asteroid 2024 ON was 350m across, not a “planet-killer” but large enough to destroy an entire country and lead to catastrophic global climate impacts.
The concerning thing was that it was spotted less than two months ago – leaving little time to do anything to prevent an impact, if it was heading right for us.
That’s all the more reason for missions like Hera and DART to learn as much as possible about the nature of the asteroid threat, as well as how to defend against it.
Hera will swing by Mars in 2025 to help propel it towards its destination. It’s due to arrive at Didymos and Dimorphos in October 2026.
The sole surviving guest of a lunch where three others died after being served food laced with toxic mushrooms has told an Australian court that the actions of murderer Erin Patterson have left him feeling “half alive”.
Ian Wilkinson, who received a liver transplant and spent months in hospital after the poisoning in July 2023, described how he had been left traumatised as he delivered his victim impact statement at Patterson’s pre-sentencing hearing in Melbourne.
Patterson, 50, was found guilty last month of luring her mother-in-law Gail Patterson, father-in-law Donald Patterson and Gail’s sister, Heather Wilkinson, to lunch at her home in Leongatha and poisoning them with individual portions of Beef Wellington that contained toxic death cap mushrooms.
A jury also found her guilty of the attempted murder of Mr Wilkinson, Heather’s husband.

Australian mother found guilty of killing three relatives by serving toxic lunch
Speaking at the start of the two-day hearing, Mr Wilkinson, a Baptist pastor, said the death of his wife had left him bereft.
“It’s a truly horrible thought to live with that somebody could decide to take her life. I only feel half alive without her,” he said, breaking down in tears.
“It’s one of the distressing shortcomings of our society that so much attention is showered on those who do evil and so little on those who do good.”

‘I bear her no ill will’
He described Gail and Don Patterson, the parents of Erin Patterson’s estranged husband Simon Patterson, as the closest people to him after his wife and family.
“My life is greatly impoverished without them,” Mr Wilkinson said.
“I’m distressed that Erin has acted with callous and calculated disregard for my life and the lives of those I love. What foolishness possesses a person to think that murder could be the solution to their problems, especially the murder of people who have only good intentions towards her?”

He called on Patterson, who said the poisonings were accidental and continues to maintain her innocence, to confess to her crimes.
“I encourage Erin to receive my offer of forgiveness for those harms done to me with full confession and repentance. I bear her no ill will,” he said.
“I am no longer Erin Patterson’s victim and she has become the victim of my kindness.”
The court received a total of 28 victim impact statements, of which seven were read publicly.

‘An irreparably broken home’
Patterson’s estranged husband Simon Patterson – who was invited to the lunch but declined – spoke of the devastating impact on the couple’s two children.
“The grim reality is they live in an irreparably broken home with only a solo parent, when almost everyone else knows their mother murdered their grandparents,” he said in a statement that was read out on his behalf.
Patterson attended the court in person on Monday rather than watch via a video link from prison which she did during a hearing earlier this month.
The hearing is scheduled to continue on Tuesday.
Patterson faces a potential life sentence for each of the murders and 25 years for attempted murder.
She has 28 days from the day of her sentencing to appeal, but has not yet indicated whether she will do so.
Israel pounded the outskirts of Gaza City overnight, as Benjamin Netanyahu’s government vowed to press on with a planned offensive on the city.
Families streamed out of the city as the explosions hit.
“I stopped counting the times I had to take my wife and three daughters and leave my home in Gaza City,” said Mohammad, 40.
“No place is safe, but I can’t take the risk. If they suddenly begin the invasion, they will use heavy fire.”

Others said they would prefer to die and not leave.
“We are not leaving, let them bomb us at home,” said Aya, 31, who has a family of eight, adding that they couldn’t afford to buy a tent or pay for the transportation.
“We are hungry, afraid and don’t have money,” she said.

Witnesses said that overnight they heard nonstop explosions in Zeitoun and Shejaia.
Tanks shelled houses and roads in Sabra, and buildings were blown up in Jabalia.
On Sunday, the IDF said its forces had returned to combat in Jabalia to strengthen its control of the area and dismantle militant tunnels.

It added that the operation there “enables the expansion of combat into additional areas and prevents Hamas terrorists from returning to operate in these areas.”
This month, Israel approved a plan to seize control of Gaza City. The offensive isn’t expected to start for another few weeks.
In the meantime, mediators in Egypt and Qatar are trying to resume ceasefire talks between the two sides.
On Friday, Israel’s defence minister Israel Katz said that Gaza City will be razed unless Hamas releases all its remaining hostages and ends the war on Israel’s terms.

Around half of Gaza’s two million residents currently live in the city and on Friday a global hunger monitor said that Gaza City and its surrounding areas are officially suffering from famine that will likely spread.
Israel said the monitor ignores steps Israel has taken since late July to increase aid supplies into and across Gaza.
Eight more people died of malnutrition and starvation in Gaza, according to the Hamas-run Gaza health ministry on Saturday.
281 people, including 114 children, have now died of malnutrition and starvation since the war started, according to the ministry.
The war began on 7 October 2023, when Hamas-led gunmen killed around 1,200 people in southern Israel, mainly civilians, and took 251 hostages.
Since then, Israel has killed at least 62,000 Palestinians, according to the Gaza health ministry, and internally displaced nearly its entire population.
Two married couples have died after a British car veered off the road and crashed in Germany, according to police.
The fatal accident happened shortly after midnight on Saturday in the trees near a highway in the Kassel district, north of Hesse in central Germany.
The 32-year-old male driver, a 31-year-old female passenger, a 32-year-old female passenger, and a 30-year-old female passenger all died at the scene, despite the efforts of German emergency services.
Sky News understands UK officials have not been contacted for assistance.
At roughly 12.30am on Saturday, the car appears to have veered off the road and crashed into nearby trees around 30m from the road, according to the Kassel police department.

One of the victim’s phones automatically alerted the emergency services to the incident, who sent an ambulance to the scene.
Soon, fire engines, ambulances, command vehicles and emergency support vehicles were all dispatched.

The emergency workers who dealt with the victims were immediately supported by the specialist mental health workers at the fire station in Reinhardshagen.
“This high number of deaths is an extraordinary operation for our Reinhardshagen Volunteer Fire Department,” said a fire department spokesperson.
“For some of the emergency personnel, it is the first time they have been confronted with death in this way.
“Therefore, a great deal is being done to help us process these images. We will also discuss this among ourselves and within families, because not everyone can easily shake off what they have seen.”
An investigation into the accident is ongoing and is being conducted by the Hofgeismar police station.
