BEIJING \u2014\u00a0Chinese\u00a0researchers\u00a0want to send more than 20 of China\u2019s largest\u00a0rockets\u00a0to practice turning away a sizable asteroid \u2014 a technique that may eventually be crucial if a killer rock is on a collision course with Earth.<\/p>\n

The idea is more than science<\/a> fiction. Sometime between late 2021 and early 2022, the United States will launch a robotic spacecraft to intercept two\u00a0asteroids\u00a0relatively close to Earth.<\/p>\n

When it arrives a year later, the NASA spacecraft will crash-land on the smaller of the two rocky bodies to see how much the asteroid\u2019s trajectory changes. It will be humanity\u2019s first try at changing the course of a celestial body.<\/p>\n

At China\u2019s National Space Science Center,\u00a0researchers\u00a0found in simulations that 23 Long March 5\u00a0rockets\u00a0hitting simultaneously could deflect a large asteroid from its original path by a distance 1.4 times the Earth\u2019s radius.<\/p>\n

Their calculations are based on an asteroid dubbed Bennu, orbiting the sun, which is as wide as the Empire State Building is tall. It belongs to a class of rocks with the potential to cause regional or continental damage.\u00a0Asteroids\u00a0spanning more than 1 km would have global consequences.<\/p>\n

The science center cited a recently published study in Icarus, a journal on planetary science.<\/p>\n

Long March 5\u00a0rockets\u00a0are key to China\u2019s near-term space ambitions \u2014 from delivering space station modules to launching probes to the moon and Mars. China has successfully launched six Long March 5\u00a0rockets\u00a0since 2016, with the last one causing some safety concerns as its remnants re-entered the atmosphere in May.<\/p>\n

\u201cThe proposal of keeping the upper stage of the launch rocket to a guiding spacecraft, making one large \u2018kinetic impactor\u2019 to deflect an asteroid, is a rather nice concept,\u201d said Professor Alan Fitzsimmons from the Astrophysics Research Centre at Queen\u2019s University Belfast.<\/p>\n

\u201cBy increasing the mass hitting the asteroid, simple physics should ensure a much greater effect,\u201d Fitzsimmons told Reuters, although, he added, the actual operation of such a mission needs to be studied in greater detail.<\/p>\n

Current estimates show there is roughly a 1% chance a 100-meter-wide asteroid would strike Earth in the next 100 years, said Professor Gareth Collins at Imperial College London.<\/p>\n

\u201cSomething the size of Bennu colliding is about 10 times less likely,\u201d Collins said.<\/p>\n

Altering an asteroid\u2019s path presents a lower risk than blasting the rock with nuclear explosives, which may create smaller fragments without changing their course, scientists say.\n <\/p><\/div>\n
