But NASA says it is being targeted as a more effective way to test the crash method instead of striking a single asteroid flying through space. 美国宇航局表示,这是一种更有效的测试碰撞方法的方法,而不是撞击在太空中飞行...
Data from the observations will help scientists to learn about the surface of the Dimorphos asteroid, how much material was kicked up by the crash, the speed at which it was ejected, and whether the force of the collision resulted in the release of large chunks of material or mainly fine ...

The plan is to crash the spacecraft into Dimorphos when the asteroid system is at its closest to Earth—about 6.8 million miles away. (重达610千克的Dart航天器计划发射到目标Didymos小行星,这是一对无害的小行星,被称作Dimorphos的163米直径的小行星,围绕一个直径更大、被称为 Didymos(希腊语“...

Researchers expect the crash to shorten the asteroid's orbital period by about 10 minutes, but it will take a few days to a few weeks for telescopes around the world and in space, including the Hubble and James Webb space observatories, to make the measurements needed to nail ...
He was talking after NASA launched its first mission to deflect an asteroid. The DART (Double Asteroid Redirection Test) spacecraft, built with the sole purpose of being crashed against "moonlet" Dimorphos, left California in the late hours of the evening to head towards the asteroid a...

NASA’s Double Asteroid Redirection Test, a planetary defense mission, will lift off on November 23 from Vandenberg Space Force Base in California. The spacecraft will deliberately crash into a small moon orbiting a near-Earth asteroid.
