China Plans Asteroid Impact Mission Ahead of 2030

China is charting an ambitious course in planetary defense, planning a mission to directly impact an asteroid with a spacecraft before 2030. This initiative, outlined in a new paper, appears to surpass NASA's recent Double Asteroid Redirection Test (Dart) in its objectives and execution.

Unlike Dart, which served as a proof-of-concept by slightly altering one asteroid's orbit around another, China's mission aims for a more impactful outcome. The plan is to directly change an asteroid's trajectory relative to Earth, with the potential to even break the celestial body apart. This was stated by a team led by Li Mingtao, chief scientist for planetary defense at the China National Space Administration.

The mission's spacecraft is projected to strike its target at a velocity exceeding 9 kilometers per second. This is significantly faster than the 6.1 km/s achieved by NASA's Dart. The planned impact is set to occur during a close approach to Earth, estimated to be within approximately 7 million kilometers, sometime in 2029 or 2030, according to the paper currently under peer review for the Journal of Deep Space Exploration.

The sheer speed of the planned impact is staggering, equivalent to over 26 times the speed of sound at sea level. This aggressive approach underscores China's growing capabilities and commitment to developing robust planetary defense strategies.
