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.

Marco Rubio warns Cuba could be Trump administration’s next target

U.S. Secretary of State Marco Rubio did not rule out that Cuba’s communist government could become the next target of the Trump administration, just one day after the arrest of Venezuelan strongman Nicolás Maduro.

In an interview on Meet the Press, Rubio issued a warning to Havana, stating that Cuban authorities are “in a lot of trouble.”

“Is the Cuban government the next target of the Trump administration?” journalist Kristen Welker asked.
“Well, the Cuban government is a major problem. Yes,” Rubio replied.
“So that’s a yes?” Welker pressed.
“I think they’re in a lot of trouble, yes,” the Secretary of State added.

In a separate appearance, Rubio—who is the son of Cuban immigrants—claimed that Venezuela’s intelligence services were “full of Cubans” and said the island nation had effectively taken control of Venezuela.

“In some cases, one of the biggest challenges Venezuelans face is having to declare their independence from Cuba,” Rubio said from President Trump’s Mar-a-Lago club. “They basically tried to colonize the country from a security standpoint. So yes, if I were living in Havana and part of the government, I would at least be worried.”

During a press conference on Saturday, President Trump himself said the United States seeks to be surrounded by “good neighbors.”

“It’s very similar in the sense that we want to help the people of Cuba, but we also want to help those who are forced to leave and live in this country,” Trump said. He also described the island as a “nation in decline” that is “not doing very well right now.”

The Cuban government has not yet responded to Rubio’s remarks. However, as a staunch ally of Maduro’s regime, Cuban authorities strongly condemned recent explosions and U.S. operations in Caracas.

“All nations in the region must remain alert, as the threat looms over everyone. In Cuba, our determination to fight is firm and unbreakable. The decision is one and only one: Homeland or Death,” Cuban officials said in a statement.

Trump signals possible expansion of U.S. regional policy beyond Venezuela

U.S. President Donald Trump said on Saturday that Cuba could become a subject of discussion as part of a broader regional policy, highlighting the possibility that Washington may expand its focus beyond Venezuela amid rising tensions in Latin America.

The remarks suggest that the White House is considering a recalibration of its strategy toward the region, in a context shaped by recent actions and warnings related to political stability and hemispheric security.

World leaders react to U.S. attacks on Venezuela, sparking global divide

The following are international reactions to the U.S. attacks carried out on Saturday against Venezuela:

Chinese Ministry of Foreign Affairs

China said it was “deeply shocked” and strongly condemned the use of force by the United States against a sovereign country, as well as the use of force against the president of that nation.

“China firmly opposes this hegemonic behavior by the United States, which seriously violates international law, infringes upon Venezuela’s sovereignty, and threatens peace and security in Latin America and the Caribbean,” the ministry said. It urged Washington to comply with international law and the purposes and principles of the United Nations Charter, and to cease actions that violate the sovereignty and security of other countries.

French Foreign Minister Jean-Noël Barrot

Barrot stated that the military operation that led to the capture of Nicolás Maduro violates the principle of non-use of force, which underpins international law. He stressed that no lasting political solution can be imposed from outside and that only sovereign peoples can decide their own future.

Russian Ministry of Foreign Affairs

Russia said the United States had committed an act of armed aggression against Venezuela, describing the move as deeply troubling and condemnable.

“The pretexts used to justify such actions are unfounded,” the ministry said, adding that ideological animosity had prevailed over pragmatism and the willingness to build relations based on trust and predictability.

Moscow emphasized the need to prevent further escalation and to focus on resolving the crisis through dialogue. It reiterated that Latin America should remain a zone of peace, as declared in 2014, and that Venezuela must be guaranteed the right to determine its own destiny without external — especially military — interference.

Russia also said it supports calls by Venezuelan authorities and Latin American leaders for an urgent meeting of the United Nations Security Council.

United Nations

UN spokesman Stéphane Dujarric said Secretary-General António Guterres continues to stress the importance of full respect for international law, including the UN Charter. He added that the secretary-general is deeply concerned that international legal norms were not respected.

Government of Argentina and President Javier Milei

Argentine President Javier Milei, a close regional ally of Donald Trump, posted on X: “FREEDOM MOVES FORWARD. LONG LIVE FREEDOM, DAMN IT,” alongside a video showing him at a summit describing Maduro as a threat to the region and supporting the pressure exerted by Trump on Caracas.

In a statement, the Argentine government praised “the decision and determination shown by the President of the United States and his administration in the recent actions taken in Venezuela that led to the capture of the dictator Nicolás Maduro, leader of the Cartel of the Suns.”

Argentina said it hopes these developments represent a decisive step forward in the fight against narcoterrorism in the region.

Mexican Foreign Ministry

Mexico strongly condemned and rejected the unilateral military actions carried out in recent hours by U.S. armed forces against targets in Venezuelan territory, calling them a clear violation of Article 2 of the United Nations Charter.

The Mexican government reiterated that dialogue and negotiation are the only legitimate and effective means to resolve disputes and reaffirmed its willingness to support any effort aimed at facilitating dialogue, mediation, or accompaniment to preserve regional peace and prevent confrontation.
