The American space agency NASA is making final preparations to crash a spacecraft into an asteroid in the world's first planetary defense test. 美国宇航局正在为航天器撞击小行星做最后准备,这是世界上首次进行行星防御试验。 T...
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“...
The mission's aim is to deliberately crash into Dimorphos to change the asteroid's motion in space, according to NASA. This collision will be recorded by LICIACube, or Light Italian Cubesat for Imaging of Asteroids, a companion cube satellite provided by the Italian Space Agency. It's the ...
NASA wants to crash a spacecraft into an asteroid to change its courseGene KimJessica Orwig
The spacecraft is called DART, which means Double Asteroid Redirection Test. The $325m craft set off on its journey in November 2021. Its goal was to crash into an asteroid called Dimorphos. The mission(使命) was a su...
Seven million miles from Earth, a NASA spacecraft crashed head on into a tiny asteroid Monday at a mind-boggling 14,000 mph, the first real-world test of humanity's ability to nudge a threatening body off course before it could crash into Earth. ...
“DART will target Dimorphos, the much smaller ‘moonlet’ of a binary (two-body) asteroid system,”Kachele said. “Didymos, the primary body, safely orbits the sun and comes close enough to Earth such that scientists can observe it using ground-based telescopes. The dynamic of the binary...
NASA's upcoming mission might resemble a scene from a sci-fi disaster movie. The agency announced Sunday that it's sending spacecraft above the Earth to crash into an asteroid's moonlet to change the body's trajectory. The mission, a Double Asteroid Redirection Test (DART), will be the...
If an asteroid were to threaten the safety of life on Earth in the future, this kinetic impactor mission may reveal how to deflect it, thus saving us all.
launch activities for the agency’s first planetary defense test mission, the Double Asteroid Redirection Test (DART). The mission will help determine if intentionally crashing a spacecraft into an asteroid is an effective way to change its course. DART’s target asteroid is not a ...
