China Hopes To Redirect a Nearby Asteroid Within the Next Four Years

The global effort to protect Earth from dangerous asteroids is set to become stronger, as China has announced its intentions to test an asteroid redirect system as early as 2025. Reader InfiniteZero writes: Speaking to China Central Television on Sunday, Wu Yanhua, deputy head of the China National Space Administration (CNSA), described China's preliminary plans to embark on the planetary defense project, according to Chinese state-owned news agency Global Times. Wu's comments coincided with Space Day, an annual event that commemorates the 1970 launch of China's first satellite, Dongfanghong-1, in 1970. For the proposed test, Wu said a probe would closely survey a near-Earth object prior to smashing into it. Known as kinetic impaction, the idea is to alter the orbital trajectory of a threatening asteroid by directing a large, high-speed spacecraft into the object. NASA is currently running a similar test, known as the Double Asteroid Redirection Test, or DART, which seeks to deliberately crash a space probe into Dimorphos -- a tiny asteroid -- later this year.
