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.

Mexico requests extradition of ‘Mini Lic’ for murder of journalist Javier Valdez

The Mexican government has requested the extradition of Dámaso López Serrano, a former high-ranking member of the Sinaloa Cartel, who is accused of masterminding the 2017 murder of Mexican journalist Javier Valdez, the Attorney General’s Office announced on Tuesday.

López Serrano, known as “Mini Lic,” was arrested last Friday in Virginia, United States, on charges of fentanyl trafficking, a crime he committed while on parole.

“This is the key issue for us, he [López Serrano] is the mastermind of this murder. The rest of the perpetrators are already processed and in jail, he was the one missing,” said Attorney General Alejandro Gertz.

“We immediately made the extradition request,” the official added during the routine morning press conference of President Claudia Sheinbaum.

Valdez, an award-winning reporter specializing in drug trafficking and correspondent for AFP and the newspaper La Jornada, was murdered on May 15, 2017, in front of the office of his magazine Riodoce in Culiacán, the capital of Sinaloa state.

“Mini Lic” was originally arrested in 2017 when he voluntarily turned himself in to U.S. authorities and pleaded guilty to trafficking methamphetamine, heroin, and cocaine. In 2022, he was released on parole.

Gertz confirmed that the Mexican Attorney General’s Office had requested López Serrano’s extradition “countless times,” but Washington had declined to act on the request because he had become a “protected witness” for the U.S. government and “was providing a lot of information.”

“Now, with this situation where they themselves are acknowledging that this individual is still committing crimes, I think there are more than enough reasons for them to support us,” the prosecutor added.

The Sinaloa Cartel is one of the largest drug trafficking organizations in Mexico and was founded by Joaquín “El Chapo” Guzmán, who is serving a life sentence in the United States.

Culiacán has been shaken by a wave of murders since the arrest of Ismael “Mayo” Zambada, another key leader of the cartel alongside Guzmán, on July 25 in New Mexico, United States.

Cuba’s government stresses openness to serious, respectful U.S. relations

Cuba reiterated on Tuesday its willingness to engage in dialogue with the United States, just weeks before Republican President Donald Trump assumes office. During his first term, Trump halted the historic rapprochement between the two countries, which had been initiated just ten years earlier by Democrat Barack Obama.

“It will not be Cuba that proposes or takes the initiative to suspend the existing dialogues, to suspend the existing cooperation. Not even the discreet exchanges on some sensitive issues,” said Cuban Deputy Minister of Foreign Affairs Carlos Fernández de Cossío at a press conference in Havana.

“We will be attentive to the attitude of the new government, but Cuba’s stance will remain the same as it has been for the last 64 years. We are willing to develop a serious, respectful relationship with the United States, one that protects the sovereign interests of both countries,” he added.

His statements come on the occasion of the tenth anniversary of the historic rapprochement announcement between Washington and Havana.

On December 17, 2014, Cuban leader Raúl Castro (2006-2021) and Barack Obama (2008-2016) announced the beginning of a thaw in relations, which led to the restoration of diplomatic ties in 2015, after more than half a century of confrontation.

This process of thawing bilateral relations was later halted by businessman Donald Trump, who significantly reinforced economic sanctions against the communist-ruled country. The Republican will return to the White House on January 20.

Cuba, under a U.S. trade embargo since 1962, was re-listed in 2021 on the “blacklist of countries supporting terrorism,” blocking financial and economic flows to the island of 10 million inhabitants.

Subsequently, the administration of current Democratic President Joe Biden made only slight adjustments to the sanctions and also kept Cuba on this list. However, his administration resumed bilateral contacts with Havana on migration issues and the fight against terrorism.

Mexican government to use church atriums for gun surrender program to combat violence

The atriums of Mexican Catholic churches will be used for the voluntary surrender of weapons in exchange for economic and legal incentives as part of a plan announced on Tuesday by the government to reduce violence.

According to the Mexican government, there is a link between the illegal trafficking of weapons—almost entirely coming from the United States—and the spiral of criminal violence that has plagued the country since late 2006, when a controversial military anti-drug offensive was launched.

“The idea is to set up areas in the church atriums where people can voluntarily surrender their weapons, and in return, they will receive financial resources based on the weapon they are turning in,” explained President Claudia Sheinbaum during her regular press conference.

The left-wing leader emphasized that the program, called “Yes to Disarmament, Yes to Peace,” guarantees that those who surrender their weapons will not face any “investigation.”

“What we want is to disarm. This will be implemented next year. We also did it in Mexico City, and it had significant results,” added the former mayor of the capital, with a population of 9.2 million.

The disarmament plan is part of the government’s “comprehensive security strategy,” one of whose pillars is promoting a culture of peace, especially in regions severely affected by organized crime violence, Sheinbaum pointed out.

More than 450,000 people have been murdered in Mexico since the government launched its military-led anti-drug operation, alongside about 100,000 people who have gone missing.

Despite being a secular state, the Mexican Catholic Church has played a key role in efforts to contain violence, with priests acting as mediators between citizens and criminals. Several clergy members have been killed for this cause.

Just last week, the Catholic hierarchy called on cartels to declare a truce in their violent actions during the celebration of the Virgin of Guadalupe on December 12 and the upcoming Christmas holidays.
