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.

Exclusive Tucson Neighborhood Shaken by Disappearance of Savannah Guthrie’s Mother

The disappearance of Nancy Guthrie, mother of well-known U.S. journalist Savannah Guthrie, has shaken the exclusive Catalina Foothills neighborhood in northern Tucson, Arizona. For the past eleven days, the area has become the focus of an intensive investigation and constant media attention.

The 84-year-old woman was last seen on January 31, when she returned home after a family dinner. Since then, authorities have released few details about the suspected abduction.

“It is worrying that an elderly person could be the victim of a crime like this in her own home; we are a community of retirees,” Mario Ruiz, a resident who lives near the property, told EFE.

He explained that neighbors in the area tend to respect each other’s privacy, and many homes do not even have fences, surrounded only by the desert landscape about 110 kilometers from the Mexican border.

Support for the family is visible in an improvised altar set up outside Guthrie’s house. Flowers, candles and a message written on a stone — “Please pray, bring her home” — reflect the concern felt by the community.

During a visit to Catalina Foothills on Wednesday, a strong presence of FBI agents could be seen patrolling nearby roads and neighborhoods in search of any clue that might help locate Guthrie.

Officers have been checking bushes, trash containers and surrounding areas near the residence, which is located in one of Tucson’s most exclusive districts, close to shopping centers, private golf courses and resorts.

Over 50 Civil Groups Urge House to Impeach DHS Secretary Kristi Noem

More than 50 civil society organizations, including Latino collectives and migrant advocacy groups, on Tuesday urged the U.S. House of Representatives to open impeachment proceedings against Homeland Security Secretary Kristi Noem, whom they accuse of leading a migration policy that is “violent, reckless, and contrary to the Constitution.”

The request was submitted through a letter sent to House Speaker Mike Johnson and other legislative leaders. In the document, the organizations argue that Noem has encouraged repressive practices that have left multiple victims and have “intentionally undermined the mission of the Department of Homeland Security (DHS).”

Among the signatories are Voto Latino, Freedom for Immigrants (FFI), Hispanic Federation, UnidosUS, and the Latino Victory Project. The groups emphasized that at least 187 lawmakers already support the impeachment initiative introduced in January by Representative Robin Kelly for alleged “high crimes and misdemeanors.”

The accusations include the alleged obstruction of congressional access to migrant detention centers and the excessive use of force, with at least 14 people shot since July 2025. They also cite three documented deaths, including those of U.S. citizens Renee Good and Alex Pretti.

The organizations further criticized the detention of migrant children, pointing to the case of five-year-old Liam Conejo Ramos, arrested in Minnesota last month, which sparked nationwide controversy.

They also denounced that operations carried out by Immigration and Customs Enforcement (ICE) have resulted in due process violations, unlawful detentions of Indigenous citizens, and disregard for court orders. According to the signatories, Noem has “dismantled” civil rights protections within the DHS and has shown a lack of understanding of constitutional principles such as habeas corpus.

Guatemala to Phase Out Longstanding Medical Cooperation Agreement with Cuba

Guatemala’s government announced on Tuesday that it will end this year a cooperation agreement with Cuba that has brought doctors from the Caribbean nation to work in the Central American country.

Guatemala’s Health Ministry told EFE that the program, which has been in place for nearly three decades, will be phased out progressively throughout 2026.

According to the same source, there are currently 412 Cubans in Guatemala under the agreement, including 333 physicians.

Cuban medical brigades assigned to Guatemala have traditionally been deployed to various regions of the country to provide primary health care to local communities.

“The decision follows a technical assessment aimed at strengthening the sustainability of the national workforce and consolidating the public health system’s own capacities,” the Guatemalan ministry said.

Earlier this week, lawmaker Sonia Gutiérrez, from the left-wing Winaq party, warned that the move “could be an inhumane act that threatens the health and lives of the country’s most vulnerable populations,” given the historic importance of Cuban doctors in providing medical care.

For that reason, the legislator summoned Health Ministry authorities to Congress, as permitted by law, to provide further details about the decision.

Former human rights ombudsman Jordán Rodas Andrade also weighed in on social media, recalling that “for 27 years Cuban doctors have been the backbone of health care in Guatemala’s most neglected areas,” and stressing that “ending this agreement is an act of ingratitude that leaves the most vulnerable unprotected.”

President Bernardo Arévalo’s government told EFE that, in order to guarantee continued care, it will implement a gradual replacement plan that includes hiring national personnel.
