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.

WHO worker killed as Israeli forces fire on Gaza medical convoy

An employee of the World Health Organization (WHO) was killed on Monday in Gaza Strip after Israeli forces opened fire on a medical convoy transporting patients for evacuation, according to witnesses and official accounts.

The Israel Defense Forces (IDF) said the vehicle approached troops in a “threatening manner,” alleging that the driver accelerated toward soldiers despite warning shots. “The troops fired warning shots. The vehicle continued advancing, and additional fire was directed at it,” the military said in a statement.

The army also claimed the vehicle lacked clear markings and was therefore treated as a potential threat.

However, survivors disputed that account. Raed Aslan, a passenger in the convoy, told reporters in Khan Younis that the vehicles were clearly marked with WHO insignia. “The vehicle was clearly identified as belonging to the WHO,” he said, adding that an Israeli tank blocked the road and fired at the driver despite the route being empty.

The convoy was transporting patients to the Rafah crossing, the only exit point available for medical evacuations abroad, as Israel does not permit transfers to Jerusalem or the West Bank.

The incident adds to a series of controversial cases involving Israeli military actions against humanitarian convoys. In April 2024, seven workers from World Central Kitchen were killed in an Israeli strike in Deir al-Balah. The military initially cited a “misidentification,” despite the vehicles being clearly marked.

Similarly, in March 2025, 15 paramedics, rescuers, and a UN worker were killed near Rafah. Israeli authorities first claimed emergency lights were off, but video evidence later contradicted that assertion.

A subsequent investigation by organizations including Forensic Architecture found that Israeli forces fired hundreds of rounds at the convoy, and that the vehicles were later destroyed and buried along with the bodies before being recovered days later.

The latest incident is likely to intensify scrutiny over the conduct of military operations in Gaza, particularly regarding the safety of humanitarian personnel and medical evacuations.

NASA’s Orion sets record as farthest crewed mission from Earth

NASA’s Orion spacecraft set a new milestone on Monday, becoming the crewed space mission to travel the farthest distance from Earth, surpassing the record set by Apollo 13, which reached 400,171 kilometers from the planet.

The Orion capsule, part of the Artemis II mission, achieved the record at 12:57 p.m. Eastern Time as it continued its journey toward the gravitational sphere of influence of the Moon.

The milestone came less than an hour before the crew was scheduled to begin observation activities during its planned lunar flyby.

“From here, in the ‘Integrity Cabin,’ as we surpass the greatest distance humans have ever traveled from Earth, we do so honoring the extraordinary efforts and achievements of those who came before us in human space exploration,” said Canadian astronaut Jeremy Hansen.

The mission, which launched last Wednesday from Cape Canaveral, is designed to orbit the Moon and return to Earth within ten days. According to the schedule, the spacecraft is expected to begin its lunar flyby at 2:45 p.m. ET, concluding around 9:20 p.m.

Petro accuses top guerrilla leader of bribing officers to evade military strikes

Colombian President defends his government's social reforms

The president of Colombia, Gustavo Petro, said Saturday that the country’s most wanted guerrilla leader is bribing members of the security forces to obtain advance information and evade military operations.

According to the government, Iván Mordisco, a dissident leader of the now-defunct FARC, is currently on the run in the जंगल following an الجيش bombardment last week that killed six of his closest collaborators in the department of Vaupés.

Authorities believe the guerrilla commander had been at the site shortly before the operation. “He buys off the commanders who are supposed to capture him; that’s how he escapes the bombings, but leaves his own people to die. He is warned before every strike,” Petro wrote on social media platform X.

The six individuals killed in the strike were part of Mordisco’s security ring, according to Defense Minister Pedro Sánchez.

Local media reported that one of those killed was a woman known as “alias Lorena,” who was allegedly Mordisco’s partner and the mother of his child.

After failed attempts to negotiate peace, Petro’s administration has shifted to a more aggressive military strategy against the guerrilla leader. In recent months, three of Mordisco’s brothers have been captured and now face charges including homicide, kidnapping, and arms trafficking.
