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.

Former U.S. vice president Dick Cheney dies at 84
Dick Cheney, former U.S. vice president under George W. Bush and a chief architect of the 2000s “war on terror,” died Monday night at age 84.
According to a family statement, Cheney passed away due to complications from pneumonia and cardiovascular disease.
Cheney, who rose to political prominence as White House Chief of Staff under President Gerald Ford in the 1970s, went on to become one of the most influential vice presidents in U.S. history during the Bush administration (2001–2009). He was widely known as one of the strongest advocates for the 2003 invasion of Iraq.
In his later years, however, Cheney emerged as a vocal critic of the Republican Party under Donald Trump’s leadership.
“Dick Cheney was a great man who taught his children and grandchildren to love our country and to live with courage, honor, love, kindness, and a passion for fishing,” his family said in a statement.

Sheinbaum maintains 70% approval despite growing discontent in Mexico
Seven out of ten Mexicans — 70% — approve of President Claudia Sheinbaum’s performance a little over a year into her term, even as disapproval reached its highest level in October at 30%, according to a monthly survey published by the newspaper El Financiero.
The approval rating marks a slight decline compared to September (73%), August (74%), and especially February, when Sheinbaum peaked at 85%. Meanwhile, disapproval rose to 30%, three points higher than in August and double the levels recorded between January and March, when just 15% of respondents disapproved of her leadership.
Of the 1,000 Mexicans surveyed, 59% rated the government’s response to last month’s deadly storms — which left 83 people dead and 16 missing — as good or very good. Additionally, 56% gave positive marks to cleanup and recovery efforts, while 40% viewed them negatively.
Support programs for affected families received 53% positive and 42% negative evaluations. Sheinbaum’s visits to impacted areas generated a narrower split: 50% approval versus 45% disapproval.
The president’s empathy stood out as her most valued attribute, earning 63% favorable ratings, followed by honesty (59%), leadership (59%), and ability to deliver results (47%).

Shootout in Sinaloa leaves 13 gunmen dead as authorities rescue kidnapping victims
A confrontation between Mexican security forces and an armed group in the troubled state of Sinaloa left 13 gunmen dead and four others arrested, Security Minister Omar García Harfuch reported on Monday.
Sinaloa, located on the Pacific coast, has been shaken for more than a year by a violent power struggle between factions of a powerful local cartel — a conflict that has resulted in at least 1,700 homicides, including 57 minors, and nearly 2,000 disappearances.
The shootout occurred around 12:45 p.m. local time (18:45 GMT) in the municipality of Guasave, where authorities were able to rescue nine kidnapped individuals following the clash. Officers also seized seven vehicles, long weapons, and tactical equipment, according to the minister’s post on X.
García Harfuch explained that security forces “were attacked by an armed group hiding under a bridge” while patrolling the La Brecha community of Guasave, prompting an “immediate response” from authorities.
The detainees and seized items have been turned over to Mexico’s federal prosecutor’s office, he added.
The internal war within the Sinaloa Cartel erupted after the capture of longtime leader Ismael “El Mayo” Zambada, who was betrayed and extradited to the United States in July 2024 by the son of his former partner Joaquín “El Chapo” Guzmán.
Guzmán has been serving a life sentence in a U.S. prison since 2019.
