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.

Haitian authorities mobilize nationwide as gangs threaten confrontation with police
Haiti’s National Police (PNH) declared a state of maximum alert after the leader of the Viv Ansanm armed coalition, Jimmy Chérizier — known as “Barbecue” — urged the population to stay indoors amid the prospect of clashes with security forces carrying out an offensive against gang groups.
The threats came days after the PNH, the Haitian Armed Forces (FAD’H), and the Gang Suppression Force (GSF) launched a large-scale operation against the 400 Mawozo gang, which for years has controlled and kidnapped residents in Tabarre and Croix-des-Bouquets, north of the capital.
The police announced the suspension of all vacations and leave for officers “in order to mobilize all police personnel, with the goal of ensuring optimal security for the population and responding to any eventuality.” Authorities reported that operations will continue specifically in Croix-des-Bouquets, territory controlled by 400 Mawozo under the command of Lanmò Sanjou.
In recent days, security forces located and raided several hideouts used by criminal groups, managing to kill or force the retreat of gang members from strategic areas. Police Director General Vladimir Paraison visited the barracks of the units involved in the operations to express his “appreciation for the courage and commitment of the police in their relentless battles to restore order and uphold the law.”
Chérizier — for whom the United States has offered a $5 million reward — urged citizens on Sunday to remain in their homes so the gangs could confront police forces and “avoid becoming victims.”
“The time has come, Haitian people, to unite to liberate this country,” he declared in a message shared on social media.

U.S. House poised to approve bill requiring declassification of Epstein files
A group of lawmakers in the U.S. House of Representatives said on Tuesday that a bill requiring the Department of Justice to declassify documents related to the case of billionaire Jeffrey Epstein is expected to pass with “overwhelming” support.
Democratic Representative Ro Khanna, the sponsor of the proposal, urged the Senate not to allow delays or amendments. “I expect it to pass by an overwhelming majority in the House. I don’t want politicians playing games with this. They need to pass it in the Senate without changes,” he said from Capitol Hill, joined by Republicans Thomas Massie, Marjorie Taylor Greene, and several Epstein victims.
The vote is scheduled for Tuesday at 2:00 p.m. local time, after 218 lawmakers from both parties forced House Speaker Mike Johnson to bring the measure to the floor.
U.S. President Donald Trump, who has been criticized by Democrats for his past friendship with Epstein, stated that he would sign the bill if it passes both chambers of Congress. His support came after a shift in his position, following his name appearing in leaked documents.
Representative Marjorie Taylor Greene, a frequent ally of the president, publicly confronted Trump in recent days over the issue. Standing alongside several Epstein victims, she defended her backing of the bill despite Trump calling her a “traitor.” “These women have fought the most horrible battle that no woman should ever have to fight (…) even against the president of the United States,” she said.
Taylor Greene added that the “real test” will be whether the Department of Justice complies with releasing the documents once the bill is enacted. “Or everything will remain sealed under the pretext of ongoing investigations,” she warned.
Haley Robson, one of the victims, also spoke during the press event. “I’m traumatized, I’m not stupid,” she said firmly, arguing that attempts by certain sectors to delay the process have caused tremendous emotional harm. “This is not political. This is America. This is the land of freedom,” she stated.

Five mexicans detained in North Carolina immigration raids, Sheinbaum confirms
Mexico’s President Claudia Sheinbaum confirmed on Tuesday that five Mexican citizens were detained during immigration raids carried out over the weekend in North Carolina, United States. She indicated that the federal government is already providing assistance and consular protection to those affected.
“There are five Mexican nationals in custody, and the Consulate General of Mexico in Raleigh is in communication with them to provide assistance and consular protection,” Sheinbaum said during her morning press conference. She reiterated that protecting Mexicans abroad is a priority for her administration, and that the Foreign Ministry will closely follow the case.
The announcement comes after an operation known as Charlotte’s Web, conducted by U.S. immigration authorities in the city of Charlotte, the state’s financial hub. The raid resulted in at least 81 arrests, including Mexican and Honduran nationals.
The operation focused on targeting “illegal aliens with criminal records,” according to the Department of Homeland Security (DHS), which cited more than 1,400 outstanding arrest warrants that have not been executed due to so-called sanctuary policies in certain cities.
However, North Carolina Governor Josh Stein stated that “the vast majority” of those detained do not have criminal records. Stein urged the public to document immigration operations and protest peacefully, as already witnessed in cities such as Los Angeles, Chicago, and Portland.
One of the most widely shared cases online is that of Willy Aceituno, a U.S. citizen born in Honduras, who reported being violently detained by immigration agents despite having valid documentation. DHS responded by accusing him of “erratic behavior” and claiming that an agent was injured after a civilian crashed their vehicle during the operation.
