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.

Macron meets Machado, stresses need for democratic transition in Venezuela

Emmanuel Macron met on Monday at the Élysée Palace with Venezuelan opposition leader María Corina Machado, where they discussed the importance of advancing a democratic transition in Venezuela.

In a message shared on social media, Macron highlighted Machado’s commitment to freedom and stressed the need to achieve a transition that is peaceful and respects the will of the Venezuelan people.

“I received María Corina Machado, Nobel Peace Prize laureate. Together, we discussed her commitment to freedom and the importance of achieving a democratic, peaceful transition in Venezuela that respects the will of its people,” he wrote.

For her part, Machado expressed her “deep gratitude” to Macron and to France for their support of democracy and freedom in Venezuela.

“We have gone through a long and painful journey, and we are now very close to freedom. Venezuela will become a nation of free and equal men and women—prosperous, safe, and united,” she said.

Trump says Iran seeks new talks after failed negotiations in Pakistan

Donald Trump said on Monday that Iran has reached out to United States to resume negotiations, following the collapse of recent talks held in Islamabad.

“We’ve been contacted by the other side,” Trump told reporters, adding that Iran is eager to reach a deal “at all costs.” Speaking from the Oval Office, he reiterated that his main objective is to prevent the Islamic Republic from acquiring nuclear weapons and warned that he will not allow Iran to “blackmail” the international community.

After negotiations between Washington and Tehran ended without agreement on Sunday, Trump announced that the U.S. would move to block the Strait of Hormuz, a critical route for global oil trade.

The waterway had already been disrupted by Iran in response to a U.S. and Israeli offensive launched on February 28, causing significant shocks to the global economy.

In a post on Truth Social, Trump further warned that any Iranian vessel attempting to bypass the U.S. naval blockade in the strait would be “eliminated immediately.”

The renewed tensions have pushed oil prices higher, while global stock markets have reacted negatively to the lack of an agreement in Islamabad.

Trump orders U.S. control of Strait of Hormuz after failed Iran talks

U.S. President Donald Trump announced on Sunday that the United States will take control of the Strait of Hormuz“effective immediately,” following the collapse of negotiations with Iran held in Islamabad.

In a post on Truth Social, Trump said he had ordered the U.S. Navy to block vessels attempting to enter or exit the strategic waterway, a key route for global energy trade.

“The meeting went well, agreement was reached on most points, but the only really important one — nuclear weapons — was not approved,” Trump said, referring to the talks with Iranian representatives.

The president also stated that he had instructed authorities to intercept ships in international waters that had paid tolls to Iran to transit the strait, calling such payments “illegal.” He further accused Tehran of hindering an agreement by deploying mines in the area, describing the move as “international extortion.”

Trump added that the United States will undertake efforts to clear mines from the strait and expressed confidence that a future agreement ensuring free navigation could eventually be reached.

The announcement came after Vice President JD Vance and special envoys Steve Witkoff and Jared Kushner briefed the president on the outcome of the negotiations, considered the highest-level contacts between the two countries since the 1979 Islamic Revolution.

While Trump acknowledged that enough progress had been made to maintain a temporary truce, he criticized Iran for remaining unwilling to abandon its nuclear ambitions, calling its position “very inflexible” on the central issue.
