Loading Something is loading. NASA just slammed a spacecraft into a distant asteroid in the name of planetary defense.The asteroid, called Dimorphos, poses no threat to Earth. But the Double Asteroid Redirection Test (DART) was designed for low stakes. NASA wants to see if it can change a space rock's orbit — just in case…

Enlarge / The DART spacecraft is prepared for launch. Monday will see NASA's first attempt at real-world testing of a technology that it hopes can protect the Earth from the dangers posed by impacts from large asteroids. The Double Asteroid Redirect Test, or DART, will smash a spacecraft into a small asteroid called Dimorphos at…

This coming Monday, NASA will broadcast its first attempt to modify the orbit of an asteroid, a capability that will be essential if we detect an asteroid that poses a threat of colliding with Earth. The planetary defense…

An illustration of an asteroid in space. NASA/JPL A previously unseen asteroid the size of a truck flew about 4,350 miles (7,000 kilometers) over the Pacific Ocean on Monday, making it one of the closest passes by our planet on record. Astronomers had no notice of asteroid 2020 JJ's existence, as it was discovered using the…

Artist's impression of one big space rock. NASA/JPL-Caltech An asteroid the size of a mountain cruised through our cosmic neighborhood Wednesday and humanity survived, because even a close pass in space terms isn't actually that close.  In fact, asteroid 1998 OR2 was always no closer than 3.9 million miles (6.3 million kilometers), putting it over…
