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 to Send High-Level Delegation to Ecuador to Ease Trade Tensions
Colombia’s Ministry of Foreign Affairs confirmed on Friday that, at the instruction of President Gustavo Petro, a high-level delegation will travel to Ecuador in an effort to normalize bilateral relations, which have deteriorated following the imposition of reciprocal tariffs.
“In line with Colombia’s policy of good neighborliness and the spirit of cooperation and integration that guides its foreign policy,” the Foreign Ministry said in a statement, adding that the delegation will be led by Foreign Minister Rosa Villavicencio and Defense Minister Pedro Sánchez.
“Following instructions from the Presidency of the Republic, and as has been publicly reiterated, the Colombian delegation expects to reaffirm Colombia’s offer of support to the Republic of Ecuador to strengthen control over phenomena stemming from transnational organized crime,” the statement said.
The Foreign Ministry noted that the delegation will attend the meeting with a full willingness to engage in dialogue and to seek concrete solutions to the unilateral measures that have affected the longstanding relationship between the two neighboring countries.
Trade tensions between Ecuador and Colombia escalated on January 21, when Ecuadorian President Daniel Noboaimposed a 30% tariff on Colombian products, citing a lack of cooperation in anti-drug efforts. Colombia responded with similar measures and the suspension of energy exports, while Ecuador increased transportation costs for Colombian crude oil.
Business associations in both countries have warned that the dispute is harming both economies and have called on the governments to resolve their differences through dialogue.

Super Bowl Halftime Show Puts Bad Bunny—and Immigration Politics—Back in the Spotlight
The long-standing argument that sports and politics should not mix may be put to the test on Sunday during the Super Bowl halftime show, which will be headlined by Puerto Rican superstar Bad Bunny, a choice that has sparked backlash from segments of the U.S. right wing.
Just one week after his headline-making appearance at the Grammy Awards—where he sharply criticized the United States’ anti-immigration policies—Bad Bunny will once again take center stage on the global spotlight with his performance at the NFL final in Santa Clara, California.
Beyond the expectations surrounding the show itself, speculation has grown over whether the artist could again use the platform to protest policies associated with the administration of former President Donald Trump, in front of an audience expected to exceed 120 million viewers in the United States alone.
In fact, one of the most popular Super Bowl prop bets this year revolves around whether the Puerto Rican singer will deliver a direct message against ICE (U.S. Immigration and Customs Enforcement), similar to the one he delivered at the Grammys last Sunday.
While few expect Bad Bunny to repeat such a pointed statement, the mere speculation highlights the delicate balance the NFL must manage during the most-watched broadcast of the year.
The world’s most powerful sports league has drawn criticism from the MAGA movement since announcing in September that Bad Bunny would headline a halftime show largely performed in Spanish.
Trump himself declined to attend the matchup between the New England Patriots and the Seattle Seahawks, despite having made history last year as the first sitting U.S. president to attend a Super Bowl. He described the musical lineup—which also includes outspoken critics such as Green Day—as “a terrible choice” that would “sow hatred.” In response, his supporters have organized an alternative event dubbed the “All-American Halftime Show,” featuring like-minded artists such as Kid Rock.

Venezuela Debates Broad Amnesty Law Covering 27 Years of Chavismo
Venezuela’s Parliament began debating on Thursday a sweeping amnesty bill that would cover the 27 years of Chavismo in power, while explicitly excluding serious human rights violations and crimes against humanity.
The proposed legislation, titled the “Amnesty Law for Democratic Coexistence,” was introduced by interim President Delcy Rodríguez, who assumed power following the capture of Nicolás Maduro during a U.S. military operation.
The legislative session was convened for Thursday afternoon, with lawmakers holding an initial discussion focused on the general principles of the bill. This phase precedes a consultation process with civil society, after which the proposal will move to a final debate examining each article individually.
According to a draft of the bill obtained by AFP, the amnesty would apply to individuals accused of crimes such as “treason,” “terrorism,” and “incitement to hatred,” charges that were frequently brought against political prisoners over the past decades. The scope also includes offenses ranging from acts of rebellion to punishments imposed for social media posts or messages sent through private messaging services.
The bill’s explanatory text emphasizes reconciliation, stating that it seeks to move away from “vengeance, retaliation, and hatred” in favor of “opening a path toward reconciliation.”
However, the proposal explicitly excludes from its benefits crimes such as “serious human rights violations, crimes against humanity, war crimes, intentional homicide, corruption, and drug trafficking.”
These exclusions, the text notes, are based on strict compliance with the Venezuelan Constitution, which already prohibits granting amnesties or pardons for such offenses.
