NASA on Monday successfully struck a tiny asteroid more than 7 million miles from Earth with a 1,000-pound spacecraft, completing the world’s first planetary defense mission. The Double Asteroid Redirection Test (DART) spacecraft slammed into the asteroid Dimorphos at roughly 7:14 p.m. ET at a speed of more than 14,000 miles per hour. It’s the…
Instead of returning home, Ben’s jump in this week’s Quantum Leap found him in the body of astronaut David Temura aboard the space shuttle Atlantis in 1998. After finding Ben’s video and a mysterious jump drive, Addison was understandably upset that her fiancé was keeping secrets from her — especially since they fell in love while […]
NASA’s Double Asteroid Redirection Test (DART) spacecraft slammed into the asteroid Dimorphos on Monday to change its path and test planetary defenses in the event an asteroid were on a collision course with Earth. Video is courtesy of NASA TV.
With Hurricane Ian bearing down on the Florida coast, NASA has decided to move its multibillion-dollar Space Launch System moon rocket to safety. For days, NASA and weather forecasters had been watching the storm take shape in the Caribbean Sea, and they made advance preparations for a rollback from Kennedy Space Center’s Launch Complex 39B to the Vehicle Assembly Building. Over the weekend, mission managers decided not to proceed with a third attempt on Tuesday to launch the 322-foot-tall, 5.7
Footage captured at the Sutherland Observing Station in South Africa shows the moment NASA deliberately crashed a spacecraft into an asteroid on Monday, September 26, to trial technology that may protect Earth from potential asteroid collisions.According to NASA, the Double Asteroid Redirection Test (DART) is the first-ever mission “dedicated to investigating and demonstrating one method of asteroid deflection by changing an asteroid’s motion in space through kinetic impact.”The mission targeted Dimorphos, a small “moonlet” roughly the size of a football stadium, which is orbiting a larger asteroid named Didymos.This footage, captured from a telescope in South Africa operated by the Asteroid Terrestrial-impact Last Alert System (ATLAS) Project at the University of Hawaii, shows the DART spacecraft colliding with Dimorphos.

One of NASA's biggest crowd-pleasers in years is about to reach its denouement: If all goes well, the Double Asteroid Redirection Test spacecraft (or rather guided anti-space-rock missile) will impact its target at around 14,700 miles per hour. DART was launched last November and has spent the intervening months positioning itself for a perfect shot on Dimorphos, a 525-foot-wide asteroid in orbit around Didymos, which is half-a-mile wide (and more the type of object we'd need to worry about, planetarily speaking). DART itself will smack straight into Dimorphos, not to annihilate it or send it careening back out of the solar system but just to affect its orbit enough that researchers back here on Earth can tell whether this technique would actually work in an emergency.

Kevin Doreumus/NOAAAs Hurricane Ian intensifies on its way toward the Florida coast, hurricane hunters are in the sky doing something almost unimaginable: flying through the center of the storm. With each pass, the scientists aboard these planes take measurements that satellites can’t and send them to forecasters at the National Hurricane Center.

STORY: "Looks to me like we're headed straight in."Can mankind deflect an asteroid on a collision course with Earth? NASA has inched one step closer to finding out.After its DART spacecraft successfully slammed into a distant asteroid at hypersonic speed.DART, or the Double Asteroid Redirection Test, is the world's first-ever test of a planetary defense system. Humanity's first attempt to alter the motion of an asteroid or any celestial body."3...2...1..."NASA workers just outside Washington D.C. cheered as they witnessed the bullseye hit.Second-by-second images of the spacecraft crashing into the asteroid 'moonlet' known as Dimorphos, ten months after DART first launched."We have impact." The mission was devised to determine whether a spacecraft can nudge an asteroid off course through sheer kinetic force.Even just a small tilt from millions of miles away and years in advance could potentially keep our planet out of harm's way. Nancy Chabot is the DART mission's Coordination Lead. "The test went spectacularly. It was really everything that we expected, and even, honestly, more. We were sitting there watching these images come in as we got closer and closer to Dimorphos, saw those surface features, and they came into focus. I think all of us had said it would be spectacular - and it was."But while NASA's spacecraft successfully hit its intended target, whether it did anything to change its trajectory will not be known until further observations in October. Elena Adams is one of the mission's engineers. "That's our number two goal. Number one was hit the asteroid, which we've done. But now number two is really measure that period change and characterize how much ejecta we actually put out." Neither Dimorphos or its parent asteroid Didymos present any actual threat to Earth. Both are tiny compared with the cataclysmic Chicxulub asteroid that struck Earth some 66 million years ago, wiping out about three-quarters of the world's plant and animal species including the dinosaurs.Of all the near-Earth asteroids that NASA tracks, none are known to pose a foreseeable hazard.However, NASA estimates there are many more near-Earth asteroids that remain undetected.
Hurricane Ian is prompting NASA to move its moon rocket off the launch pad and into shelter, adding weeks of delay to the lunar-orbiting test flight. Mission managers decided Monday to return the rocket to its Kennedy Space Center hangar. NASA already had delayed this week’s planned launch attempt because of the approaching storm.
Since a new coronavirus launched the global pandemic that has now killed more than 6.5 million people - 16 percent of them in the United States alone - scientists in record numbers have devoted themselves full time to unraveling its mysteries. In less than three years, researchers have published more than 200,000 studies about the virus and covid-19. That is four times the number of scientific papers written on influenza in the past century and more than 10 times the number written on measles.Su
