Chinese Scientists Call For Int’l Cooperation Against Asteroid Threat

Chinese scientists have called for international cooperation in space exploration to reduce the risk of near-Earth objects.

According to the Sci-Tec report, there are more than 18,000 near-Earth asteroids - around 800 have a diameter greater than 1 km.

Researchers have discovered 180 giant impact craters on our planet, which exhibit the formidable power that a small celestial object could generate when hitting the Earth.

Evidence found in the strata in Kamba County, southwest China's Tibet Autonomous Region, showed that Earth suffered a major asteroid impact about 65 million years ago, which might have led to the extinction of dinosaurs.

Ouyang Ziyuan, a CAS academician and first chief scientist of China's lunar probe project, also believes that the danger from small celestial objects "is worth attention while we are devoted to building a community with a shared future for humanity."

"Scientists around the world should cooperate to monitor near-Earth asteroids," said Ouyang, noting that modern space technologies are capable of defending Earth from their threat.

"We can land a propeller on a potentially hazardous asteroid and with a very small force, push it away from the orbit that crosses Earth's path," Ouyang said.
