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.

FBI Says It Disrupted Alleged Plot Targeting White House During UFC Event

 

The Federal Bureau of Investigation (FBI) announced Tuesday that it had disrupted an alleged plot to attack the White House during a major Ultimate Fighting Championship (UFC) event held in Washington over the weekend.

FBI Director Kash Patel said the threat was identified on June 10 through a joint investigation involving multiple law enforcement agencies. According to Patel, swift action by authorities led to the arrest of several suspects before the alleged plan could be carried out.

“On June 10, the FBI and our law enforcement partners became aware of a potential threat targeting UFC America 250 in Washington. Thanks to the rapid response of the FBI and our partners, multiple individuals are now in custody, and the alleged attack plans were stopped before they could be executed,” Patel said.

He emphasized that the operation demonstrated the ability of security agencies to detect and prevent potential threats at large public gatherings. Patel added that the investigation remains ongoing and that additional details will be released as court proceedings move forward.

According to reports from U.S. media outlets, five individuals have been arrested so far. The suspects were identified as Tycen Proper of Ohio, Daniel Eskridge of Missouri, Abraham Hermosillo Álvarez of Nebraska, and Bryan Omar Roa and Michael Alan Thomas, both from California. Authorities are also investigating the possible involvement of 18 additional individuals.

Investigators allege that the plot involved the use of drones equipped with explosives to target buildings near the sporting event. The plan reportedly sought to trigger a mass evacuation and direct attendees toward areas where snipers were allegedly positioned. Authorities further claim that a second phase of the operation included an attempted assault on the White House.

The U.S. Secret Service confirmed that it worked closely with the FBI throughout the operation. Secret Service Director Sean Curran stated that security teams conducted extensive efforts to identify those involved and eliminate any threat to attendees and protected facilities.

The investigation reportedly uncovered communications conducted through the messaging application Signal, where several suspects allegedly discussed details related to the planned attack. A forensic analysis of one of the seized mobile phones revealed at least 23 users participating in conversations connected to the alleged planning activities.

Court documents also indicate that some of the suspects allegedly intended to target U.S. political figures. Among the reported targets were members of Congress who had received contributions from the American Israel Public Affairs Committee (AIPAC). Investigators further stated that one of the primary suspects had posted antisemitic messages and expressions of support for Adolf Hitler on social media, evidence that is now part of the ongoing judicial investigation.

Brazil helicopter crash in Rio de Janeiro kills six, including pilots and international figures

The Rio de Janeiro Civil Police confirmed on Monday the identities of three of the six victims killed in a helicopter collision that occurred the previous morning in the Recreio dos Bandeirantes neighborhood.

All three identified victims are Brazilian nationals: the pilots of the aircraft, Charles Marsillac and Alexandre Souza, and music producer Lucas Brito.

The identities of the three foreign victims have not yet been officially confirmed. They include U.S. singer Oliver Tree, Argentine YouTuber Gaspar Prim—known online as “Gaspi”—and Argentine producer Lucas Vignale, all of whom were listed on the flight manifest.

According to police, forensic experts from the Legal Medical Institute have already collected DNA samples in order to identify the foreign victims, whose bodies were severely burned.

One of the helicopters crashed into a private parking lot, triggering a fire that destroyed around twenty electric vehicles. That aircraft was carrying the pilot and four passengers, including the three foreign nationals.

The second helicopter, which had only the pilot on board, crashed approximately 100 meters away from the first impact site.

Rio de Janeiro’s deputy mayor, Eduardo Cavaliere, stated that both helicopters were operating transport flights toward Angra dos Reis on the Rio coastline and toward the mountainous region of the state.

Oliver Tree, 32, was in Brazil as part of an international tour. The artist, known for songs such as “Life Goes On” and “Miss You,” had performed to a large audience in São Paulo a week earlier and was scheduled to continue his tour in Europe.

Argentine content creator Gaspar Prim, 23, had built a following of more than two million on social media platforms, gaining popularity for humorous and often controversial video productions that had occasionally been removed by hosting platforms.

Mexico and U.S. Launch New Bilateral Security Group to Combat Fentanyl and Organized Crime

The governments of Mexico and the United States officially launched the Bilateral Implementation Group (BIG) on Friday, a new initiative aimed at strengthening cooperation on security issues and enhancing joint efforts against transnational crime.

In a statement, U.S. Ambassador to Mexico Ronald Johnson announced that he and Deputy Foreign Minister Roberto Velasco addressed officials from both countries who will lead what he described as a “new phase of bilateral cooperation.” The initiative seeks to curb the flow of fentanyl and other illicit drugs, illegal firearms, and human trafficking across the shared border.

Earlier this week, Mexico’s Ministry of Foreign Affairs had confirmed that senior security officials from both nations would meet in Mexico City on June 12 to review and advance existing cooperation agreements.

Through social media, Ambassador Johnson explained that the new bilateral group is designed to improve coordination between the two governments by placing greater emphasis on implementation, accountability, and measurable results. The effort will also focus on combating transnational criminal organizations operating across North America.

“The participation of 15 U.S. government agencies, working alongside their Mexican counterparts, reflects the seriousness of this effort and our shared commitment to delivering measurable results,” Johnson said.

The ambassador also highlighted several achievements that he attributed to ongoing bilateral cooperation. According to Johnson, maritime drug trafficking into the United States has declined by more than 95 percent, while overdose deaths have fallen by 35 percent.

He further noted that Mexican authorities have seized more than 400 metric tons of illegal drugs and dismantled over 2,300 clandestine laboratories as part of their efforts to combat organized crime and narcotics production.

The launch of the Bilateral Implementation Group marks the latest step in the security partnership between Mexico and the United States, as both countries seek to address shared challenges related to drug trafficking, arms smuggling, human trafficking, and the activities of criminal networks operating across the region.
