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.

Bogotá and Quito Seek Dialogue After Tariffs and Power Cut Escalate Tensions
Bogotá and Quito will hold an emergency bilateral summit next week amid recent developments that have strained relations between the two countries.
Tensions escalated this week after Ecuadorian President Daniel Noboa unexpectedly announced a 30% tariff on Colombian imports. Colombia responded with a reciprocal measure, imposing the same tariff on around 20 Ecuadorian products and suspending electricity exports to Ecuador.
Aware that electricity imports are critical to easing Ecuador’s recent energy crises, Quito further imposed a 30% tariff on the transportation of Colombian oil through its territory.
However, recent statements from the Ecuadorian government suggest that dialogue between the two sides has intensified in recent hours. Ecuador’s Minister of Foreign Affairs, Gabriela Sommerfeld, confirmed that active conversations are under way.
In Colombia, segments of the business sector have welcomed the prospect of negotiations. The National Business Council (Consejo Gremial Nacional, CGN), for instance, urged both governments to restore commercial relations, warning that the dispute “puts jobs and regional economic stability at risk.”

Trump-Era Defense Plan Prioritizes Border Security and Scales Back Global Commitments
The U.S. military will prioritize the defense of the homeland and the deterrence of China, while providing more limited support to its allies and elevating Latin America as a key focus of its agenda, according to a Pentagon strategic document released on Friday.
The 2026 National Defense Strategy (NDS) represents a significant shift from previous Pentagon policies, both in its emphasis on allies assuming greater responsibility with reduced backing from Washington and in its more moderate tone toward traditional adversaries such as China and Russia.
“As U.S. forces focus on defending the homeland and the Indo-Pacific, allies and partners elsewhere will assume primary responsibility for their own defense, with crucial but more limited support from U.S. forces,” the document states.
The previous defense strategy, published during President Joe Biden’s administration, described China as Washington’s most consequential challenge and characterized Russia as an “acute threat.”
The new strategy, however, calls for maintaining “respectful relations” with Beijing and makes no reference to Taiwan, the democratically governed island claimed by China and allied with the United States. It also describes the threat posed by Russia as “persistent but manageable,” particularly affecting NATO’s eastern members.
While both the Biden-era strategy and the Trump administration’s approach emphasize the importance of defending U.S. territory, they differ significantly in their assessment of the challenges facing the country.
The Trump administration’s NDS sharply criticizes the previous government for neglecting border security, arguing that this failure led to an “influx of illegal immigrants” and widespread narcotics trafficking.

Guatemala considers sending high-risk gang members to military prisons
Amid the escalating crisis in Guatemala’s prison system, the government is considering transferring high-risk gang members to military-run detention facilities, a move that analysts say could help address overcrowding and the lack of control in civilian prisons.
The debate has gained urgency following the killing of ten police officers by gang members, reportedly in retaliation after the government refused to meet demands made by Aldo Dupie Ochoa, alias “El Lobo,” leader of the Barrio 18 gang, which authorities identified as responsible for the attack.
Guatemala’s Minister of Defense, Henry David Sáenz, told local media that the possibility of relocating high-danger inmates to military brigades has not been formally discussed. However, he noted that the practice is not new to the Armed Forces and said it is something that “was already being done.”
One example is the detention center located within the Mariscal Zavala Military Brigade, in Zone 17 of Guatemala City, where several inmates are held under military supervision. The facility also houses high-profile detainees, including former official Eduardo Masaya, who faces corruption charges.
In 2015, a ministerial agreement authorized the establishment of the Zone Seventeen Detention Center within the brigade, with a maximum capacity of 114 inmates in Area A and 21 in Area B. The agreement specified that the facility would be used exclusively for civilians or military personnel considered at risk of assassination.
Additionally, since 2010, a prison has operated within the Matamoros Barracks in Zone 1 of Guatemala City, holding dangerous or high-profile inmates. However, media outlets have described these military detention centers as “VIP prisons,” particularly for former government officials such as ex-president Otto Pérez Molina.
