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.

Colombia says it would not reject Maduro asylum request as regional tensions escalate
The Colombian government stated on Thursday that it would have no reason to reject a potential asylum request from Venezuelan President Nicolás Maduro should he leave office, as regional tensions persist over the deployment of U.S. military forces in the Caribbean since August.
“In the current climate of tension, negotiations are necessary, and if the United States demands a transition or political change, that is something to be assessed. If such a transition results in him (Maduro) needing to live elsewhere or seek protection, Colombia would have no reason to deny it,” said Colombian Foreign Minister Rosa Villavicencio in an interview with Caracol Radio.
However, Villavicencio noted that it is unlikely Maduro would choose Colombia as a refuge. “I believe he would opt for someplace more distant and calmer,” she added.
Colombian President Gustavo Petro also commented on Venezuela’s situation on Wednesday, arguing that the country needs a “democratic revolution” rather than “inefficient repression.” His remarks followed the recent detention and passport cancellation of Cardinal Baltazar Porras at the Caracas airport.
“The Maduro government must understand that responding to external aggression requires more than military preparations; it requires a democratic revolution. A country is defended with more democracy, not more inefficient repression,” Petro wrote on X (formerly Twitter), in a rare public criticism of the Venezuelan leader.
Petro also called for a general amnesty for political opponents and reiterated his call for forming a broad transitional government to address Venezuela’s prolonged crisis.
Since September, U.S. military forces have destroyed more than 20 vessels allegedly carrying drugs in Caribbean and Pacific waters near Venezuela and Colombia, resulting in over 80 deaths.
U.S. President Donald Trump has repeatedly warned that attacks “inside Venezuela” will begin “soon,” while Maduro has urged Venezuelans to prepare for what he describes as an impending external aggression.

Cuba battles out-of-control dengue and chikungunya epidemic as death toll rises to 44
Cuba is facing a severe dengue and chikungunya epidemic that has already claimed at least 44 lives, including 29 minors, according to the Ministry of Public Health (Minsap). The outbreak—now considered out of control—has expanded across the entire country amid a critical shortage of resources to confront the emergency.
Authorities report more than 42,000 chikungunya infections and at least 26,000 dengue cases, though they acknowledge significant underreporting as many patients avoid seeking care in health centers where medicines, supplies, and medical personnel are scarce. The first cluster was detected in July in the city of Matanzas, but the government did not officially use the term “epidemic” until November 12.
Chikungunya—virtually unknown on the island until this year—causes high fever, rashes, fatigue, and severe joint pain that can last for months, leaving thousands temporarily incapacitated. Dengue, endemic to the region, triggers fever, muscle pain, vomiting, and, in severe cases, internal bleeding. Cuba currently has no vaccines available for either virus.
Minsap reports that of the 44 deaths recorded so far, 28 were caused by chikungunya and 16 by dengue.
The health crisis unfolds amid deep economic deterioration, marked by the absence of fumigation campaigns, uncollected garbage, and shortages of medical supplies—conditions that have fueled the spread of the Aedes aegypti mosquito, the primary vector for both diseases. “The healthcare system is overwhelmed,” non-official medical sources acknowledge.
Beyond the health impact, the epidemic is heavily disrupting economic and family life. The intense joint pain caused by chikungunya has led to widespread work absences, while hospital overcrowding has forced relatives to leave their jobs to care for the sick. In November, authorities launched a clinical trial using the Cuban drug Jusvinza to reduce joint pain, though results have not yet been released.

Ecuador on track for record violence as homicides hit highest level in Latin America again
Violence in Ecuador is expected to reach historic levels by the end of 2025, with the country set to record the highest homicide rate in Latin America for the third consecutive year, according to a report released Thursday by the Armed Conflict Location & Event Data Project (ACLED). The organization warns that criminal activity is not only persisting but could worsen in 2026.
Official figures show 7,553 homicides recorded through October, surpassing the 7,063 registered throughout all of 2024. ACLED estimates that 71% of the population was exposed to violent incidents this year, despite President Daniel Noboa’s declaration of an “internal armed conflict” in an attempt to confront powerful criminal groups.
According to the report, several factors are driving the deterioration of security: a territorial war between Los Chonerosand Los Lobos, the two most influential criminal organizations in the country; the fragmentation of other groups after the fall of their leaders; and Ecuador’s expanding role as a strategic hub for regional drug trafficking.
Since 2021, violence has forced the internal displacement of around 132,000 people, while more than 400,000 Ecuadorians — equivalent to 2% of the population — have left the country. Between January and November alone, violent deaths rose 42%, fueled by prison massacres and clashes between rival gangs.
The report warns that conditions may deteriorate further. Ecuador has been added to ACLED’s 2026 Conflict Watchlist, which highlights regions at risk of escalating violence. The expansion of Colombian armed groups such as FARC dissidents and the ELN, state weakness, and a potential rerouting of drug trafficking corridors from the Caribbean to the Pacific intensify the threat.
“The president is facing a wave of violence that shows no signs of easing,” the report concludes.
