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.

Iran rejects negotiations as tensions escalate with United States

Iran has no intention of entering negotiations and will continue to resist, Foreign Minister Abbas Araghchi said Wednesday night, dismissing recent statements by U.S. President Donald Trump about possible talks.

Speaking to state television, Araghchi argued that Washington’s call for negotiations reflects a position of weakness. He added that the Islamic Republic seeks to end the war on its own terms, ensuring that such a conflict does not recur in the future.

Meanwhile, the White House issued a stark warning, stating that Trump would “unleash hell” on Iran if it refuses to accept a deal to end the conflict. Despite Tehran’s rejection, U.S. officials maintained that discussions remain ongoing.

White House spokesperson Karoline Leavitt reinforced the administration’s position, warning that failure to acknowledge what she described as Iran’s military defeat would result in even stronger action from Washington.

The increasingly aggressive rhetoric from both sides has diminished hopes for a near-term de-escalation in the conflict, which began following U.S. and Israeli strikes against Iran on February 28.

As tensions continue to rise, the prospect of a diplomatic resolution remains uncertain amid conflicting narratives and escalating threats from both governments.

Maduro appears again in New York court amid drug trafficking charges

Ousted Venezuelan president Nicolás Maduro appeared in a New York federal court on Thursday for the second time since his capture on January 3 during a U.S. military operation in Caracas.

Maduro, 63, and his wife, Cilia Flores, 69, have been held in a detention facility in Brooklyn for nearly three months. Their only previous court appearance took place on January 5, when Maduro declared himself a “prisoner of war” and pleaded not guilty to drug trafficking charges.

A large police convoy departed the detention center early in the morning, heading toward the federal courthouse in Manhattan, where the hearing was scheduled. Security around the building was reinforced as both supporters and opponents gathered outside.

Among those present was Venezuelan educator Carlos Egana, who expressed frustration and called for justice, reflecting the polarized reactions surrounding the case. At the same time, left-wing activists displayed banners demanding Maduro’s release and criticizing U.S. foreign policy.

Maduro governed Venezuela from 2013 until his removal from power earlier this year. Following his ouster, Delcy Rodríguez assumed the interim presidency, initiating a shift in relations with the United States.

The former leader faces multiple charges, including narco-terrorism conspiracy, cocaine importation, and illegal possession of weapons.

During Thursday’s hearing, scheduled for 11:00 a.m. local time, Maduro’s legal team was expected to push for the dismissal of the case, while also addressing disputes over how his legal defense will be financed amid ongoing U.S. sanctions.

His lawyer, Barry Pollack, has argued that restrictions on accessing Venezuelan state funds could affect Maduro’s right to legal representation, adding another layer of complexity to a case with significant political and international implications.

German president says trust in U.S. leadership is ‘lost’ amid global tensions

German President Frank-Walter Steinmeier said on Tuesday that trust between the United States and its Western allies has been “lost,” warning that the damage could persist beyond the presidency of Donald Trump.

“The rupture is very deep, and the loss of trust in U.S. great power policy is significant—not only among its allies, but also, as I observe, globally,” Steinmeier said during a speech in Berlin marking the 75th anniversary of Germany’s Foreign Ministry.

Referring to the future of transatlantic relations, he stated that “there is no return to the situation before January 20, 2025,” the date marking the start of Trump’s second term in the White House.

“Even a future U.S. administration will no longer be able to resume the role of a benevolent hegemon guaranteeing a liberal international order,” added Steinmeier, who previously served as Germany’s foreign minister.

He also criticized the war against Iran, describing it as “contrary to international law” and calling it “a political mistake with serious consequences.”

“This war is avoidable and unnecessary,” he said.

Although the German presidency is largely ceremonial, Steinmeier’s remarks reflect a broader concern within Germany, aligning with the government’s cautious stance while going further in tone.
