Remember That Asteroid NASA Deflected in a Test of Saving Earth? We Have Bad News

In late 2022, NASA celebrated its Double Asteroid Redirection Test (DART) as a massive success, a proof of concept for saving humanity in case a similar space rock were to ever head straight for Earth. The small spacecraft smashed into asteroid Didymos' moonlet Dimorphos at a violent 14,000 mph, knocking it severely off course. But three years later, astronomers found that the collision had some unintended consequences. As detailed in a paper published last week in the Planetary Science Journa

Deflecting a Killer Asteroid Is More Complicated Than NASA Thought

gizmodo.com Ellyn Lapointe 2025-08-02 16:00:42

In 2022, NASA rammed a spacecraft into an asteroid to see if it could alter its orbital period around its parent asteroid. The mission, dubbed the Double Asteroid Redirection Test (DART), aimed to determine whether humanity could theoretically save itself from a catastrophic asteroid impact. DART collided with Dimorphos, a small moonlet orbiting a larger asteroid called Didymos, on September 26, 2022. The results of the impact blew NASA’s expectations out of the water, shortening Dimorphos’s or

The Download: hunting an asteroid, and unlocking the human mind

If you were told that the odds of something were 3.1%, it might not seem like much. But for the people charged with protecting our planet, it was huge. On February 18, astronomers determined that a 130- to 300-foot-long asteroid had a 3.1% chance of crashing into Earth in 2032. Never had an asteroid of such dangerous dimensions stood such a high chance of striking the planet. Then, just days later on February 24, experts declared that the danger had passed. Earth would be spared. How did t

Inside the most dangerous asteroid hunt ever

technologyreview.com Robin George Andrews 2025-08-09 15:30:00

While possible impact locations included patches of empty ocean, the space rock, called 2024 YR4, also had several densely populated cities in its possible crosshairs, including Mumbai, Lagos, and Bogotá. If the asteroid did in fact hit such a metropolis, the best-case scenario was severe damage; the worst case was outright, total ruin. And for the first time, a group of United Nations–backed researchers began to have high-level discussions about the fate of the world: If this asteroid was going

NASA Reveals First-Ever Full Image of Peanut-Shaped Asteroid Donaldjohanson

gizmodo.com Gayoung Lee 2025-08-15 08:57:11

Scientists with NASA’s Lucy mission are finally wrapping up the process of refining the data gathered by the spacecraft’s April 20 encounter with Donaldjohanson, an asteroid in our solar system’s main asteroid belt. And it’s, uh, as peanut-shaped as we first saw it. Earlier this year, Lucy’s Long Range Reconnaissance Imager snapped an image of Donaldjohansson while quickly swooping past it, at a distance of about 600 miles (960 kilometers), with the smallest visible features measuring around 13

Rubin Observatory’s Stunning Result Proves It’s a ‘Game Changer’ for Spotting Dangerous Asteroids

gizmodo.com Ellyn Lapointe 2025-08-23 01:00:05

Astronomers usually keep their eyes on the sky, but on Monday, June 23, the community turned its attention toward Washington, D.C., as scientists from the Vera C. Rubin Observatory unveiled the telescope’s first images. Many have waited more than 20 years to see Rubin in action, and its initial findings did not disappoint. Rubin, a joint initiative of the National Science Foundation (NSF) and the Department of Energy’s (DOE) Office of Science, recently conducted its first 10 hours of test obser

An exceedingly rare asteroid flyby will happen soon, but NASA may be left on the sidelines

arstechnica.com Unknown 2025-08-25 10:00:10

A little less than four years from now, a killer asteroid will narrowly fly past planet Earth. This will be a celestial event visible around the world—for a few weeks, Apophis will shine among the brightest objects in the night sky. The near miss by the large Apophis asteroid in April 2029 offers NASA a golden—and exceedingly rare—opportunity to observe such an object like this up close. Critically, the interaction between Apophis and Earth's gravitational pull will offer scientists an unpreced

This Chinese Spacecraft Is Traveling to One of Earth’s Quasi-Moons

wired.com Javier Carbajal 2025-09-17 00:00:00

The China National Space Administration has shared the first image from its Tianwen-2 probe, which is en route to Kamo’oalewa, a near-Earth asteroid. The image was captured by a camera onboard the probe, which is currently more than 3 million kilometers from Earth, and shows one of its wings with its solar panels deployed. It is also the first glimpse the CNSA has offered of its space probe, which launched on May 29 on a Long March 3B rocket from the Xichang Satellite Launch Center in Zeyuan To

NASA Makes Big Update to Asteroid Potentially on Collision Course With Earth in 2032

gizmodo.com Isaac Schultz 2025-06-04 05:35:30

The potentially hazardous asteroid 2024 YR4 caused consternation over the last few weeks as its odds of hitting Earth in 2032 dramatically rose. Now, those odds have plummeted to near-zero, as astronomers’ calculations of the asteroid’s path have been updated to indicate that Earth is almost certainly not in the space rock’s plans. Almost. According to NASA’s Center for Near-Earth Object Studies (CNEOS), the asteroid’s current chance of hitting the planet in 2032 is 0.28%, or a 1-in-360 shot. T

The Odds of a City-Killing Asteroid Hitting Earth Keep Rising

wired.com Eric Berger 2025-06-04 05:00:00

An asteroid discovered late last year is continuing to stir public interest as its odds of striking planet Earth less than eight years from now continue to increase. Two weeks ago, when Ars first wrote about the asteroid, designated 2024 YR4, NASA’s Center for Near Earth Object Studies estimated a 1.9 percent chance of an impact with Earth in 2032. NASA’s most recent estimate has the likelihood of a strike increasing to 3.2 percent. Now that’s not particularly high, but it’s also not zero. Ars

Killer Asteroid Could Be Headed for Some of the World's Most Populous Cities

futurism.com Unknown 2025-06-04 05:25:49

According to NASA's Jet Propulsion Lab, near-Earth asteroid 2024 YR4 now has a 3.1 percent chance of colliding with our planet on December 22, 2032. That makes it the highest-threat asteroid ever detected, as Euronews reports. As of late January, the probability was sitting at just 1.3 percent, which then rose to 2.1 percent last week before rising yet again. Worse yet, the space agency suggests the asteroid could hit densely populated areas of our planet — if it were to make an impact just un

Asteroid's Chances of Smacking Earth Increase. Here's What to Know

cnet.com Amanda Kooser 2025-06-04 03:10:00

It's not great news, but don't panic: Astronomers spotted an asteroid that has a roughly 3.1% chance of impacting Earth on Dec. 22, 2032. Space agencies are monitoring the newly discovered asteroid and still learning more about its size and path, so don't mark your calendar for doomsday just yet. Although the odds of the asteroid hitting Earth have increased recently, that number is not set in stone. There's still a lot to learn about the space rock. Designated 2024 YR4, the asteroid was first
