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.

President Sheinbaum Hails Fátima Bosch’s Miss Universe Win as a Victory for Women’s Voices
Mexican President Claudia Sheinbaum praised Fátima Bosch on Friday for winning the Miss Universe 2025 title, recognizing her as a symbol of courage for Mexican women and highlighting her stance against an act of injustice during the international pageant.
Bosch, a native of Tabasco, claimed the crown at the competition held in Thailand. Her participation drew significant attention following an incident involving the director of Miss Universe Thailand, Nawat Itsaragrisil, who told her to remain silent for not sharing event-related content on her social media platforms. The remark prompted Bosch to walk out of the room in protest, an action supported by several other contestants.
President Sheinbaum denounced expressions like “you look prettier when you’re quiet,” asserting: “Women look more beautiful when we speak up and participate. And she raised her voice, saying, ‘This is unjust, I don’t agree.’”
Fátima Bosch, 25, became the fourth Mexican woman to win the Miss Universe crown, joining Lupita Jones (1991), Ximena Navarrete (2010), and Andrea Meza (2020).
Bosch triumphed over Thailand’s Veena Praveenar, who placed as first runner-up, and Venezuela’s Stephany Abasaly, who took third place. This year’s pageant featured contestants from 120 countries and territories, including nine mothers, one transgender woman, a genocide survivor, and the first-ever Palestinian contestant in the competition’s history.

Peru Orders Arrest of Betssy Chávez Amid Diplomatic Rift With Mexico
Peru’s Judiciary issued an international arrest warrant and ordered five months of pretrial detention on Friday for former Prime Minister Betssy Chávez, who is facing charges of attempting a coup d’état and is currently taking refuge in the Mexican Embassy in Lima.
Peru severed diplomatic relations with Mexico, arguing that the asylum granted to Chávez constitutes interference in its internal affairs. The former prime minister is accused of participating in former President Pedro Castillo’s attempted coup in December 2022.
“The court orders five months of pretrial detention for the defendant Betssy Chávez Chino, as well as national and international search and arrest notices,” the Judiciary stated.
Judge Juan Carlos Checkley argued that there is a “clear” flight risk and a significant chance of jeopardizing the upcoming oral trial.
The Supreme Anti-Corruption Prosecutor’s Office said it secured pretrial detention for Chávez “on charges of rebellion and, alternatively, conspiracy, to the detriment of the State.”
Chávez, who has been on trial since March 2025, faces a potential 25-year prison sentence. She has been staying for 18 days at the Mexican Embassy residence in Lima, awaiting a safe-conduct pass to leave the country.
The Peruvian government announced on November 7 that it intends to seek a review of regional diplomatic asylum regulations, following Mexico’s decision to grant protection to Chávez.
Relations between the two countries deteriorated after Castillo’s ousting, when Mexico granted asylum to the former president’s wife and two children. Since then, both governments have withdrawn their ambassadors.

Paraguay launches dengue vaccination for children in high-risk areas
Dengue fever, transmitted by the Aedes aegypti mosquito, remains a persistent threat in tropical and subtropical countries such as Paraguay, where it claimed the lives of 132 people among nearly 100,000 infections during the 2023–2024 Southern Hemisphere summer, according to official data. However, that figure was lower than the record set in the 2012–2013 season, when 252 deaths were reported among roughly 130,000 infections.
“Today marks a very important step toward protecting our children and bringing peace of mind to families,” Paraguay’s Minister of Health, María Teresa Barán Wasilchuk, said in a speech on Wednesday.
The vaccine will be administered to children between 6 and 8 years old in municipalities with the highest incidence of dengue cases in the past five years. Authorities will use TAK-003 (Qdenga), developed by Takeda—one of Japan’s largest pharmaceutical companies—which was approved by the World Health Organization (WHO) in 2024.
“We celebrate this step, which positions Paraguay as a country with one of the most robust immunization programs,” said Héctor Castro, director of the Acosta Ñu Pediatric Hospital. “We will work tirelessly to ensure this government decision becomes a success in the fight against this scourge.”
Vaccinating children against dengue “is not only a historic and public health milestone, but also a humanitarian one,” Castro added during remarks delivered at the hospital in San Lorenzo, near the capital, Asunción.
