NASA spaceship deflected asteroid in test to save Earth

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.

Suspect Armed With Shotgun and Knives Detained at White House Correspondents Dinner
U.S. authorities confirmed Saturday that the suspect who stormed into the White House Correspondents’ Association Dinner while President Donald Trump was attending acted alone, adding that there is no ongoing threat to the public following the incident, which left one Secret Service agent injured.
Acting Metropolitan Police Department chief Jeff Carroll said during a press conference that the suspect was carrying “a shotgun, a handgun, and multiple knives” when he attempted to pass through a Secret Service security checkpoint inside the hotel lobby at approximately 8:36 p.m. local time.
“At this point, everything indicates that this was a lone actor, a lone gunman,” Carroll stated, adding that investigators have found no preliminary evidence suggesting the involvement of additional suspects.
During the exchange of gunfire inside the hotel corridors, the suspect was not struck by bullets but was subdued by law enforcement officers and later transported to a hospital for medical evaluation.
A member of the United States Secret Service Uniformed Division was shot during the incident, though the bullet was stopped by the officer’s ballistic vest, preventing serious injuries. The agent was taken to a hospital and is reportedly “in good spirits,” according to Carroll.
The shooting prompted the immediate evacuation of President Trump, Melania Trump, and several senior officials attending the event after multiple gunshots were heard outside the hotel’s main ballroom.

U.S. allows Venezuela to fund Maduro and Cilia Flores’ legal defense
Until now, the U.S. administration had blocked the Venezuelan government from covering the legal fees of Nicolás Maduro and his wife, Cilia Flores, who is also jailed and facing drug trafficking charges, due to international sanctions imposed on Venezuela.
The couple’s legal team had relied on that argument in an attempt to have the indictment dismissed, claiming that preventing a defendant from accessing counsel of their choice violates rights guaranteed under the Sixth Amendment of the U.S. Constitution.
However, the U.S. Treasury Department will now allow “defense attorneys to receive payments from the Government of Venezuela under certain conditions,” New York prosecutor Jay Clayton wrote in a letter dated Friday to Judge Alvin Hellerstein, who is overseeing the case.
According to the letter, the funds must have become available after March 5, 2026, and cannot come from Venezuelan oil sales regulated in the United States.
Since Maduro’s removal from power in early January, former Vice President Delcy Rodríguez has served as Venezuela’s interim leader.
The United States effectively controls Venezuelan crude exports, with revenues deposited into special accounts supervised by Washington.
Court documents filed on Friday show that the defense acknowledged the sanctions exemption and, for now, withdrew its motion seeking dismissal of the charges.

U.S. Sanctions Network Linked to Fentanyl Trafficking Across India, Guatemala and Mexico
The United States Department of State announced sanctions on Thursday against 23 individuals and companies allegedly linked to an international fentanyl production and smuggling network operating in India, Guatemala and Mexico.
According to the State Department, the network supplied precursor chemicals to the Sinaloa Cartel, which the United States has designated as a Foreign Terrorist Organization.
Washington declared fentanyl, a powerful synthetic opioid, a weapon of mass destruction last year due to its role in the ongoing overdose crisis in the United States.
“By targeting the entire supply chain — from chemical suppliers in Asia to logistical intermediaries in Central America and cartel-linked networks in Mexico — the Trump Administration is dismantling networks that destabilize governance across our hemisphere and threaten U.S. security,” the State Department said.
In a separate statement, the Office of Foreign Assets Control detailed sanctions against three Indian chemical and pharmaceutical companies: Sutaria, Agrat and SR Chemicals, along with a sales executive accused of supplying precursor chemicals to contacts in Guatemala and Mexico.
In Guatemala, authorities sanctioned J and C Import and Central Logística de Servicios, as well as intermediary Jaime Augusto Barrientos.
The OFAC also designated several intermediaries and import companies operating in the Mexican state of Sinaloa.
As part of the investigation, U.S. authorities identified Ramiro Baltazar Félix as a member of Los Mayos, a faction of the Sinaloa Cartel, and Alejandro Reynoso, accused of operating clandestine drug laboratories in Guadalajara.
