NASA on Tuesday said it had succeeded in deflecting an asteroid in a historic test of humanity’s ability to stop an incoming cosmic object from devastating life on Earth.

The fridge-sized Double Asteroid Redirection Test (DART) impactor deliberately smashed into the moonlet asteroid Dimorphos on September 26, pushing it into a smaller, faster orbit around its big brother Didymos, said NASA chief Bill Nelson.

“DART shortened the 11 hour 55 minute orbit to 11 hours and 23 minutes,” he said. Speeding up Dimorphos’ orbital period by 32 minutes exceeded NASA’s own expectation of 10 minutes.

“We showed the world that NASA is serious as a defender of this planet,” added Nelson.

The asteroid pair loop together around our Sun every 2.1 years, and pose no threat to our planet.

But they are ideal for studying the “kinetic impact” method of planetary defense, in case an actual approaching object is ever detected.

DART’s success as a proof-of-concept has made a reality of science fiction — notably in films such as “Armageddon” and “Don’t Look Up.”

Astronomers rejoiced in stunning images of matter spreading out thousands of miles in the wake of the impact — pictures collected by Earth and space telescopes, as well as a mini satellite that had traveled to the zone with DART.

Pseudo-comet

Thanks to its temporary new tail, Dimorphos, which is 530-foot (160-meter) in diameter or roughly the size of a big Egyptian pyramid, has turned into a manmade comet.

But quantifying just how well the test worked required an analysis of light patterns from ground telescopes, which took a few weeks to become apparent.

The binary asteroid system, which was around 6.8 million miles (11 million kilometers) from Earth at impact, is visible only as a single dot from the ground.

Ahead of the test, NASA scientists said the results of the experiment would reveal whether the asteroid is a solid rock, or more like a “rubbish pile” of boulders bound by mutual gravity.

If an asteroid is more solid, the momentum imparted by a spaceship will be limited. But if it is “fluffy” and significant mass is pushed at high velocity in the opposite direction to impact, there will be an additional boost.

Never actually photographed before, Dimorphos appeared as a speck of light around an hour before impact.

Its egg-like shape and craggy, boulder-dotted surface finally came into clear view in the last few moments, as DART raced toward it at roughly 14,500 miles (23,500 kilometers) per hour.

Mass extinction

Very few of the billions of asteroids and comets in our solar system are considered potentially hazardous to our planet, and none are expected in the next hundred years or so.

But wait long enough, and it will happen.

The geological record shows, for example, that a six-mile wide asteroid struck Earth 66 million years ago, plunging the world into a long winter that led to the mass extinction of the dinosaurs along with 75 percent of all species.

An asteroid the size of Dimorphos, by contrast, would only cause a regional impact, such as devastating a city.

Kinetic impact with a spaceship is just one way to defend the planet, albeit the only method possible with current technology.

Should an approaching object be detected early, a spaceship could be sent to fly alongside it for long enough to divert its path via using the ship’s gravitational pull, creating a so-called gravity tractor.

Another option would be launching nuclear explosives to redirect or destroy an asteroid.

NASA believes the best way to deploy such weapons would be at a distance, to impart force without blowing the asteroid to smithereens, which could further imperil Earth.

Maradona’s daughter accuses medical team of “horrible manipulation” in court

One of the daughters of Diego Maradona testified in court this Tuesday, breaking down in tears as she denounced what she described as “absolute and horrible manipulation” by her father’s medical team, during an emotional hearing in Argentina.

Gianinna Maradona stated that she and her siblings agreed to home hospitalization after doctors presented it as the best option following the neurosurgery Maradona underwent on November 3, 2020.

The football icon died on November 25 of that year, and the ongoing trial seeks to determine whether the conditions of his home care were appropriate.

According to Gianinna, what the family found at the residence where Maradona was recovering did not match what had been promised. She testified that there was no adequate medical equipment, constant monitoring, or even an ambulance available, despite assurances of continuous care.

“The manipulation was absolute and horrible,” she said during the hearing in San Isidro, near Buenos Aires.

She accused members of the medical team, including neurosurgeon Leopoldo Luque, psychiatrist Agustina Cosachov, and psychologist Carlos Díaz, of misleading the family.

“I trusted these people, and all they did was manipulate us and leave my son without a grandfather,” she added.

Later in her testimony, recalling that six years have passed since her father’s death, she became emotional and said she struggled deeply with grief in the aftermath.

Trump extends Iran ceasefire after Pakistan mediation request

The president of the United States, Donald Trump, announced on Tuesday that he will extend the ceasefire with Iran, which was set to expire on Wednesday, following a request from Pakistan.

In a statement shared on Truth Social, Trump said the truce will remain in place until Iran presents a proposal and negotiations are concluded, regardless of the outcome.

“I will extend the ceasefire until their proposal is presented and negotiations are completed, whatever the result,” the U.S. leader stated.

Trump justified the decision by claiming that Iran’s government is “deeply divided” and noting that Pakistani authorities, acting as mediators, requested a pause in military action until Iranian leaders and representatives submit a unified proposal.

Venezuelan opposition demands election date and minimum wage increase

A group of opposition members from the Zulia Humana and former political prisoners on Tuesday demanded that authorities set a date for elections in Venezuela and increase the minimum wage, which has been frozen since 2022 and is currently worth just a few cents per month according to the Banco Central de Venezuela.

During a press conference in Maracaibo, Professor Eduardo Labrador stressed the urgency of establishing an electoral timeline. “We demand that a date be set for elections so Venezuelans can have free and transparent voting. It is essential to have that date now,” he said.

Economist Rodrigo Cabezas, who served under the late President Hugo Chávez, also called for an increase in the minimum wage, arguing that it is feasible through economic policy measures, although he did not specify an amount due to limited public data.

Cabezas warned that Venezuela experienced “galloping inflation” between March of last year and March 2026, a stage that precedes hyperinflation—a phenomenon the country has already faced. However, he clarified that Venezuela is not currently in hyperinflation, expressing hope that it will not return.
