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.

U.S. Proposes Higher Citizenship Fees and Limits on Immigration Fee Waivers
The U.S. Department of Homeland Security (DHS) has proposed increasing fees related to citizenship applications, while also seeking changes to programs that reduce or waive immigration-related costs for certain applicants.
The proposal would eliminate fee waivers and reduced-fee programs for immigrants whose household incomes are at or below 400% of the federal poverty level.
However, the changes would not take effect immediately. Before receiving final approval, the proposal must go through a 60-day public comment period, allowing individuals and organizations to submit feedback.
DHS justified the proposed increases by stating that the goal is to fully cover the costs associated with processing citizenship and naturalization applications.
“Although the Department of Homeland Security has historically limited form fees to promote naturalization, the agency no longer considers that these applications should have lower costs at the expense of other immigration benefits,” the department said in the proposal document.
If approved, the reform would modify the current immigration fee structure and could impact thousands of applicants who rely on financial assistance programs to complete their citizenship process.
U.S. authorities said the measure is part of a broader review of immigration service fees and the mechanisms used to fund the administration of these programs.

Cristiano Ronaldo Makes History as First Player to Score in Six World Cups
Cristiano Ronaldo made football history on Tuesday by becoming the first player ever to score in six different editions of the FIFA World Cup.
The Portuguese forward opened the scoring in Portugal’s Group K match against Uzbekistan in Houston. Just six minutes into the game, Ronaldo found the back of the net with a right-footed strike from inside the box, sending the Portuguese fans into celebration.
The “Commander” sparked excitement throughout the stadium with his iconic celebration, as supporters joined in with his famous “Siuuu!” chant to honor another milestone in the career of one of football’s greatest stars.
At 41 years old, Ronaldo has now scored in Germany 2006, South Africa 2010, Brazil 2014, Russia 2018, Qatar 2022, and North America 2026. With his two goals in this tournament, he has surpassed Lionel Messi’s record, as the Argentine has scored in every World Cup he played except South Africa 2010.
The Portuguese captain has also reached nine World Cup goals, matching Eusébio as Portugal’s all-time top scorer in the history of the tournament.
Ronaldo’s achievement came just one day after Messi also made history by becoming the outright leading scorer in World Cup history, reaching 18 goals after scoring twice in Argentina’s 2-0 victory over Austria.
With his appearance at the 2026 World Cup, Cristiano Ronaldo has also extended another remarkable record by becoming the first player to participate in six consecutive editions of the tournament, further cementing his legacy as one of the most influential players in football history.

Mbappé Ties Klose on All-Time World Cup Scoring List After Brace Against Iraq
Kylian Mbappé moved another step closer to World Cup history on Monday, scoring twice against Iraq to reach 16 career goals in the tournament and draw level with German legend Miroslav Klose on the all-time scoring chart.
The French forward found the net in the 14th and 54th minutes of France’s Group I clash in Philadelphia, registering his second consecutive brace of the 2026 FIFA World Cup.
Mbappé’s achievement came on the same day that Argentina captain Lionel Messi set a new all-time World Cup scoring record. The Argentine star scored twice against Austria to raise his career total to 18 goals, surpassing the previous mark of 16 held by Klose.
Klose established his record on July 8, 2014, during Germany’s historic 7-1 victory over Brazil in the World Cup semifinals in Belo Horizonte.
Before facing Iraq, Mbappé was tied with German striker Gerd Müller on 14 World Cup goals. His first goal of the match lifted him to 15, drawing level with Brazilian great Ronaldo Nazário.
The second strike moved the Real Madrid forward to 16 goals, allowing him to surpass Ronaldo, match Klose’s tally, and position himself just two goals behind Messi in the race for World Cup immortality.
The match also marked a personal milestone for Mbappé, as he made his 100th appearance for the French national team.
At 27 years old, the French superstar remains firmly in pursuit of Messi’s newly established record and continues to strengthen his legacy as one of the most prolific scorers in World Cup history.
