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.

Meta Says Russia Seeks to Ban WhatsApp for Defending Secure Communication
U.S. tech giant Meta, the parent company of WhatsApp, said that Russia is seeking to ban the messaging app because it “challenges government attempts to violate people’s right to secure communication.”
Russian authorities have encouraged citizens to switch to state-backed applications, and in August they already blocked WhatsApp’s calling feature.
On Friday, the communications regulator Roskomnadzor claimed that the platform was being used to “organize and carry out terrorist acts in the country, recruit perpetrators, and facilitate fraud and other crimes.”
“If the messaging service does not comply with Russian law, it will be completely blocked,” the regulator warned.
WhatsApp remains one of Russia’s most widely used messaging services, alongside Telegram.
Moscow is pressuring both platforms to grant authorities access to user data upon request for investigations into fraud and activities the government labels as “terrorist.”
Human rights advocates fear the demand could be used to target critics of the Kremlin, President Vladimir Putin, or the war in Ukraine.

Archbishop Wenski criticizes Trump’s deportation policies, calls for stronger push for reform
The Archbishop of Miami, Thomas Wenski, has called for increased pressure on the U.S. Congress to advance comprehensive immigration reform and criticized President Donald Trump’s mass deportation policies, arguing that they “do nothing to help.”
“We need to apply more pressure on Congress so lawmakers can make the necessary changes. It is also important for the Administration to listen to our voice. We do not want to be anyone’s enemy—we are Americans,” Wenski said in an interview with EFE.
The religious leader, who heads one of the dioceses with the largest Latino and Haitian populations in the United States, issued a call to defend the rights of migrants. He also emphasized that the U.S. Conference of Catholic Bishops (USCCB) has maintained a strong and public stance in favor of migrants for decades.

Trump relaunches diplomatic push to finalize U.S.-Backed peace plan for Ukraine War
U.S. President Donald Trump announced on Tuesday that his diplomatic team will resume meetings with delegations from Russia and Ukraine in an effort to pressure both sides to accept the peace plan proposed by Washington to end the war in Ukraine.
As part of this new round of talks, U.S. Special Envoy Steve Witkoff will travel to Moscow to meet with Russian President Vladimir Putin. Meanwhile, Army Secretary Dan Driscoll will hold discussions with Ukrainian representatives to narrow differences on the remaining points of the agreement.
Trump also confirmed his intention to meet personally with Ukrainian President Volodymyr Zelensky and with Putin, though he emphasized that such meetings will only take place “when the agreement is fully finalized or in its final stage.”
The president claimed that his administration has made “tremendous progress” toward resolving the conflict and reiterated that the war “never would have started” if he had been in the White House at the onset of the crisis.
The U.S.-backed peace plan consists of 28 points and has been revised following feedback from both sides. According to Trump, only “a few points of disagreement” remain under active discussion.
One of the most controversial aspects of the proposal is the suggestion that Ukraine cede parts of the Donbas region to Russia and limit the size of its armed forces. Kyiv is working closely with Washington to soften these clauses in search of an arrangement that does not compromise its sovereignty or security.
With this diplomatic push, Trump aims to solidify his role as the main mediator in the conflict and steer the war toward a political resolution after years of devastation, humanitarian crisis, and rising global geopolitical tensions.
