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.

Washington declares State of Emergency as atmospheric river brings severe flooding
Washington Governor Bob Ferguson declared a state of emergency on Wednesday in response to severe flooding affecting several counties, where more than 75,000 people remain under evacuation alerts following heavy rainfall that has caused significant water accumulation.
An atmospheric river has battered the state since Monday, dropping several centimeters of rain and threatening serious flooding in communities near major rivers. More precipitation is expected in the coming days, and the National Weather Service (NWS) has forecast between 15 and 20 centimeters of rain from Wednesday morning through Thursday afternoon in communities along the far western region, worsening the emergency.
Rainfall totals in higher elevations near the Canadian border could exceed 20 centimeters, further increasing the risk.
“Lives will be at stake in the coming days,” Ferguson warned during a press conference.
The governor underscored the severity of the situation and said he will request an expedited federal disaster declaration from President Donald Trump’s administration to access additional resources for the emergency response.
“I want to urge all Washington residents to pay close attention to alerts from their counties and emergency management departments. If you receive an evacuation order, please follow it,” he added.
Most rivers from the Canadian border down to southwestern Washington are in flood stage. Several are expected to reach record levels, including the Skagit River, which could exceed its 1990 flood peak when water levels rose 1.2 meters.
Around 75,000 people are at risk of flooding in Skagit County, where authorities continue to maintain an evacuation watch.
The Washington National Guard and the U.S. Army Corps of Engineers have been activated to assist with evacuations and response efforts in rural areas affected by flooding.

U.S. to require five-year social media history from tourists under Visa Waiver Program
Tourists from 42 countries covered by the U.S. Visa Waiver Program would be required to provide their social media history from the past five years in order to enter the United States, according to a new proposal released Wednesday by the administration of President Donald Trump.
The initiative, led by U.S. Customs and Border Protection (CBP), aims to more thoroughly review the activity of travelers entering the country through the Electronic System for Travel Authorization (ESTA). When asked about the plan’s potential impact on tourism, Trump insisted that the United States is “doing very well.”
“We just want people to come here and be safe… We want to make sure we’re not letting the wrong people into our country,” the president said during a press conference at the White House.
The proposal, published in the Federal Register, seeks to expand the information collected from visitors entering the U.S. for up to three months under the visa waiver program.
ESTA applies to travelers from 42 countries, including the United Kingdom, Ireland, New Zealand, Australia, France, Japan, Israel and Qatar.
In addition to requiring a five-year social media history, the plan would increase the amount of personal data requested, such as phone numbers and email addresses used over the past ten years. It also calls for family details, including names, dates of birth and places of birth of the traveler’s relatives.
The proposal further includes a new mobile tool that would allow any foreign visitor to record their departure from the United States.

Six ecuadorian soldiers jailed pending trial for alleged extrajudicial execution
Six Ecuadorian soldiers were placed in pre-trial detention on Wednesday by a civilian court over an alleged extrajudicial execution, the Attorney General’s Office reported.
As part of his war on drug trafficking, President Daniel Noboa declared an internal armed conflict in 2024 and deployed the Armed Forces to the streets. Human rights organizations have since denounced military abuses and a rise in disappearances attributed to state agents.
A judge in the coastal province of Santa Elena ordered pre-trial detention for six soldiers for alleged extrajudicial execution, the prosecution stated on X. It added that the troops, now under investigation for the suspected crime, were in charge of an operation in the resort town of Salinas, during which one of the detainees died.
In a separate case involving alleged abuse of authority, a group of 17 soldiers is currently on trial for the forced disappearance of four minors whose bodies were found burned near an Ecuadorian Air Force (FAE) base.
In December 2024, Saúl Arboleda, Steven Medina, and brothers Josué and Ismael Arroyo — aged 11 to 15 — were detained by a military patrol in southern Guayaquil.
According to Amnesty International, Ecuador’s Prosecutor’s Office has received reports of at least 43 possible cases of forced disappearance since 2023, the year Noboa took office pledging a tough stance against organized crime.
