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 ...
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...
NASA wants to crash a spacecraft into an asteroid to change its courseGene KimJessica Orwig
NASA has launched a spacecraft on a mission to test technology that could one day alter the course of a dangerously large asteroid heading toward Earth.
The deliberate 14,000-mphcrash of a small NASA probeinto the asteroid Dimorphos two weeks ago nudged the 525-foot-wide body onto a slightly different course, NASA confirmed Tuesday — shaving 32 minutes off the time needed to complete one orbit around a parent asteroid known as Didymos. ...
The DART spacecraft will guide itself using technology called SmartNav, which uses computational algorithms to locate the Dimorphos asteroid and point the craft toward it. “Never in my life would I have thought I would take a couple hundred million dollar spacecraft and crash it into an astero...
DART is the agency's first planetary defense test mission and the target asteroid is not a threat to Earth. /NASA/Johns Hopkins, APL/Steve Gribben "We all think about, you know, national threats. What's the United States doing? What's China doing? What's Russia doing? This is...
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.
