NASA has successfully smashed a spacecraft into an asteroid seven million miles from Earth.

The last image from the “vending machine-sized” collider showed the surface of the asteroid Dimorphos seconds before impact.

The Double Asteroid Redirection Test (DART) is the first-ever trial of a “planetary defence system”.

If the orbit of an asteroid can be changed by an object sent into space, humanity may have a chance at protecting itself from the kind of disaster that did it for the dinosaurs.

NASA, and the international team of astronomers working with them, chose their target carefully. To prove success, they needed an asteroid they can carefully monitor following the collision. They also needed to make sure any impact wouldn’t send a previously harmless piece of rock spiralling towards Earth.

They picked a pair of asteroids: the 780 metre-wide Didymos, and its moon Dimorphos which is 160m wide – about the size of the Great Pyramid.

Because Dimorphos is already safely orbiting its bigger partner, they can study the change in its behaviour following the collision.

Dimorphos is also a fairly common size of asteroid. While significantly smaller than a kilometres-wide “planet killer”, it’s of a type easily big enough to destroy a city.

“What Dart is going up there to prove is that we actually do have a system for kinetic deflection, nudging these away and nudging them off course,” says Betsy Congdon, DART’s mechanical systems engineer at Johns Hopkins University in Maryland.

If you’ve seen Hollywood disaster movies Deep Impact, Armageddon or more recently Don’t Look Up, prepare yourself for mild disappointment.

Despite smashing a half-tonne spacecraft into Dimorphos at close to 15,000 miles an hour, the effect on the asteroid is expected to be tiny – checking its speed by just 0.4mm per second.

But over time, that should have a measurable effect on its orbit. An array of land and space-based telescopes including NASA and ESA’s new James Webb Space Telescope, will all study the asteroid to measure the outcome of the test.

Although it’s only a modest objective, the engineering involved was a major undertaking. Didymos is far too small and far away for DART to be steered into it from Earth. The probe had to use an autonomous guidance system to target the asteroid which is so small it was only visible in DART’s cameras about 50 minutes before impact. But the sat-nav seems to have worked perfectly.

The hope is, that a tiny nudge might be enough – if the impact is sufficiently far away – to deflect a future asteroid on collision course with Earth off target.

Astronomers estimate they have tracked the orbits of 95% of asteroids large enough to destroy life on Earth and none is currently on a collision course. But there are many smaller ones. According to NASA, no known asteroid larger than 140m across is likely to hit Earth in the next 100 years. But they think they’ve only found about 40% of them.

Around 66 million years ago a 10km-wide asteroid slammed into what is now the Yucatan Peninsular of Mexico. It left a crater 110 miles wide and 12 miles deep. The resulting change in the planet’s climate is thought to have caused the Cretaceous-Paleogene extinction event. The impact wiped out 75% of animal and plant species on Earth – and famously ended the reign of flightless dinosaurs.

But even small space rocks can lead to a bad day on Earth. In 2013 a 20m-wide asteroid exploded as a meteorite over the city of Chelyabinsk in the Ural region of Russia. The blast was equivalent to 500 tonnes of TNT, about a third of the force of the Hiroshima bomb. While no deaths were reported there were more than 1,400 casualties, some of them serious.

“An asteroid impact is the one kind of natural disaster that we could potentially see coming decades away,” says Prof Colin Snodgrass at the University of Edinburgh is a member of the DART team.

He’s helped set up a telescope in Kenya to monitor the impact from Earth. “If one [the size of Dimorphos] was ever discovered coming towards earth being able to do something about that seems like a very sensible technology to have.”

‘Many options’ on table for Venezuela as US mulls land attacks on drug traffickers

'Many options' on table for Venezuela as US mulls land attacks on drug traffickers

“Many options” are on the table to deal with Venezuelan drug gangs, the White House has said, as the US considers attacking on land.

President Trump is meeting his national security team on Monday and could discuss what would be a major escalation in strikes that have so far only targeted boats.

Karoline Leavitt, the president’s press secretary, did not detail what the meeting would focus on. However, Mr Trump said last week that land strikes would start “very soon”.

“There’s many options at the president’s disposal that are on the table – and I’ll let him speak on those,” Ms Leavitt told reporters.

Three killed as US strikes another alleged drug boat

American forces have carried out at least 21 strikes on boats it claims were carrying narcotics to its shores over the last few months.

The US has accused Venezuelan President Nicolas Maduro of being involved in the drugs trade – a claim he denies.

Venezuela has said the attacks, which have killed more than 80 people, amount to murder and that President Trump’s true motivation is to oust Mr Maduro and access its oil.

More on Nicolas Maduro

President Maduro – widely considered a dictator by the West – said on Monday that Venezuelans are ready “to defend [the country] and lead it to the path of peace”.

“We have lived through 22 weeks of aggression that can only be described as psychological terrorism,” he said.

Concerns have been raised over the legality of the US attacks, which the Pentagon has sought to justify by designating the gangs as foreign terror organisations.

Tensions remain high over America’s large deployment in the Caribbean Sea and eastern Pacific, which includes its flagship aircraft carrier and thousands of troops.

The US has released videos of boats being blown up but has not provided evidence – such as photos of drugs – to support the smuggling claims.

Controversy also surrounds the first incident, on 2 September, in which 11 people were killed – with a follow-up strike targeting the boat after the first attack left two survivors in the water.

US media reported defence secretary Pete Hegseth gave an order beforehand that everyone on board should be killed.

However, there are concerns about the legality of the second strike if the survivors posed no threat.

Mr Hegseth dismissed the reporting as “fake news” and insisted all actions in the region are compliant with US and international law.

“Every trafficker we kill is affiliated with a Designated Terrorist Organization,” he said on X.

President Trump said on Sunday he would not have wanted a second strike and that Mr Hegseth had denied giving such an order.

Is US about to go to war with Venezuela?

Ms Leavitt confirmed on Monday that the boat had been hit by a second strike – but denied Mr Hegseth gave the order for the follow-up.

Instead, she said he had authorised US navy vice admiral Frank Bradley to attack and the admiral acted “well within his authority and the law, directing the engagement to ensure the boat was destroyed and the threat to the US was eliminated”.

As the US weighs its next steps, Mr Trump said on Sunday he had spoken to President Maduro by phone and that the conversation went neither “well or badly”.

In recent days, he also stated that Venezuela’s airspace should be considered closed – with the South American nation calling it a “colonial threat” and “illegal, and unjustified aggression”.

White House issues update on Donald Trump's health as president undergoes MRI scan

The White House has revealed details of Donald Trump’s recent medical evaluation involving a scan of his cardiovascular system and abdomen.

The US president, 79, underwent a magnetic resonance imaging (MRI) scan in October, which was confirmed in a memo from his doctor, Sean P Barbabella.

The White House physician wrote that the cardiovascular and abdominal imaging was “perfectly normal”.

“The purpose of this imaging is preventive: to identify issues early, confirm overall health, and ensure he maintains long-term vitality and function,” said Dr Barbabella.

He added that there was “no evidence of arterial narrowing impairing blood flow or abnormalities in the heart or major vessels”.

“The heart chambers are normal in size, the vessel walls appear smooth and health, and there are no signs of inflammation, or clotting.”

As for the abdominal imaging, he wrote that “all major organs appear very healthy and well-perfused”.

More on Donald Trump

“Everything evaluated is functioning within normal limits with no acute or chronic concerns.”

He said the imaging was done “because men in his age group benefit from a thorough evaluation of cardiovascular and abdominal health”.

While speaking to reporters on Sunday, the US president said he didn’t know what part of his body was examined but added: “It wasn’t the brain because I took a cognitive test and I aced it.”

He described the results of the MRI as “perfect”.

In 2022, Donald Trump described himself as “the healthiest president that’s ever lived” but in July was diagnosed with chronic venous insufficiency (CVI) after noticing “mild swelling” in his lower legs.

Dr Barbabella said CVI, which causes blood to pool in the veins, was a “benign and common condition, particularly in individuals over the age of 70”.

Concerns were also raised in July about photos which showed bruising on the back of Mr Trump’s hand that had been covered with make-up.

Luigi Mangione shown videos of UnitedHealthcare CEO killing as defence seeks to bar evidence

Luigi Mangione has watched surveillance videos of the killing of UnitedHealthcare CEO Brian Thompson at a court appearance.

Mangione has pleaded not guilty to state and federal murder charges over the killing of Mr Thompson. The state charges carry the possibility of life in prison, while federal prosecutors are seeking the death penalty.

The 27-year-old’s lawyers are seeking to bar evidence, including a 9mm handgun and a notebook in which prosecutors say he described his intent to “wack” a health insurance executive, from his New York state trial.

Both were allegedly found in a backpack Mangione had with him when he was arrested.

Mr Thompson, 50, was shot dead on 4 December last year as he walked to a New York City hotel for his company’s annual investor conference, sparking a five-day manhunt.

Mangione was arrested after a McDonald’s employee in Pennsylvania alerted authorities to a customer who looked like the suspect in the killing.

Mangione, wearing a white shirt with a red checked pattern under a grey suit, watched without emotion as prosecutors played surveillance videos showing Mr Thompson’s killing on a Manhattan pavement, as well as his own arrest, at a court appearance in New York on Monday.

The videos, including footage from the McDonald’s restaurant in Pennsylvania where he was arrested, kicked off a hearing on Mangione’s fight to bar evidence from his trial, including the gun prosecutors say matches the one used in the early-hours attack.

After getting state terrorism charges thrown out in September, Mangione’s lawyers are focusing on what they argue was unconstitutional police conduct threatening his right to a fair trial.

They are seeking to block prosecutors from using evidence allegedly discovered in his backpack during his arrest, and statements he made to police, arguing that he was illegally searched and questioned.

Eliminating the gun and notebook would be huge wins for Mangione’s defence, and a major setback for prosecutors, depriving them of a possible murder weapon and evidence they say points to motive.

Mangione also faces seven counts of criminal possession of a weapon, and one count of possessing a false identification.

Judge Gregory Carro dismissed two terrorism counts against Mangione in September.

He found that prosecutors had not presented enough evidence that Mangione intended to intimidate health insurance workers or influence government policy.

Trial dates have not been set in either the state or federal cases.

Mangione has been held in federal custody in Brooklyn since his arrest.
