China recently made headlines when they announced plans to attack an asteroid to deflect it by 2030 as part of their Planetary Defense Initiative, in an effort to increase space science research capabilities and protect Earth from potential asteroid impacts while also improving our understanding of our solar system.
According to Chinese scientists, this mission serves a dual-purpose – one spacecraft will impact an asteroid while its partner spacecraft observes it to gather vital data about our solar system’s creation and evolution. CNSA is leading this ambitious plan.
Target Object 2015 XF261
For this mission, 2015 XF261, a 100-foot (30 meter) wide near-Earth object (NEO), was chosen as its target due to its closeness and size; making it ideal for deflection experiment. On July 9th XF261 made an extremely close flyby over Earth, traveling at 31 million miles (50 million kilometers). At that speed it flew at around 26,000 mph (42,000 kph).
China’s planned mission echoes NASA’s Double Asteroid Redirection Test (DART) mission. NASA successfully deflected an object in the Didymos binary asteroid system in September 2022 to demonstrate their feasibility.
Scientific and Defensive Objectives
A recent paper in the Journal of Deep Space Exploration detailed the goals and objectives for the proposed mission. It seeks to demonstrate defensive measures against potential near-Earth asteroid threats by conducting scientific payload demand analyses, configuring payload plans, and proposing exploration mission requirements; all of which serve as solid bases for future asteroid defense missions.
Potential Risks and Global Impact
While the mission seeks to strengthen planetary defense capabilities, questions still exist regarding the potential risks. If deflection processes go awry, this could inadvertently pose a threat to Earth; one such impact led to the extinction of dinosaurs eons ago. Therefore, successful missions like these are vitally important in safeguarding Earth.
Conclusion China’s planned asteroid deflection mission represents an important step in global efforts to safeguard Earth from potential asteroid threats. Following NASA’s DART mission, this Chinese initiative seeks to expand our understanding of solar system phenomena while showing how deflecting an asteroid may work – though success of this mission must ensure no unexpected risks to Earth are posed by deflected debris.
