In 2022, NASA's Double Asteroid Redirection Test (DART) spacecraft made history by achieving something we had only seen in movies. It altered the course of an asteroid that could potentially pose a direct threat to Earth. And while it all seemed like a success after DART hit Dimorphos at ...
Hera is headed to the asteroid Dimorphos. NASA crashed its DART spacecraft into the space rock in 2022 in an area about 11 million kilometers from Earth. The NASA mission was an experiment to test a method for changing the orbit of asteroids that might one day threaten Earth. 赫拉正前往...
根据第一段“NASA’s spacecraft Dart hit an asteroid (小行星) 11.3 million kilometers away at a speed, changing the asteroid’s orbit and lowered its cycle period by I5 minutes, the space organization announced on Monday. (国际空间组于周一宣布,美国航天局宇宙飞船Dart以极快的速度击中了1130公里...
The spacecraft being tested will crash straight into the525-foot moonlet, called Dimorphos, of the nearby asteroid Didymos. Dimorphos' size is "more typical of the size of asteroids" that would most likely be a significant threat to Earth, NASA previously said. It's a high-speed task with...

A high school teacher and his students have discovered that an asteroid (小行星) hit by a NASA spacecraft, in a test run for saving the Earth from an impact, is behaving unexpectedly. The find could have effects on future planetary defense missions. ...
The system aimed to recreate the breakup of space objects that have been hit. The researchers said their simulation method has been used in the past to recreate space objects crashing into each other. For example, the team ...
The US$325M mission was the first attempt to shift the position of an asteroid, in preparation for the day one might be on course to hit Earth
NASA will crash a spacecraft into an asteroid (小行星) to try to change its orbit, attempting to prevent humans going the same way as the dinosaurs.Earth is constantly being disturbed by small pieces of debris (碎片), but they usually burn up or break up long before they hit the ground...
Astronomers who watched the aftermath of a NASA spacecraft colliding with an asteroid released new images. Taken by the European Southern Observatory’s Very Large Telescope in Chile, they reveal detailed views of a debris cloud following the DART missio
