China Plans Ambitious Asteroid Strike Mission
China is planning a big space mission to hit an asteroid with a spacecraft.
They want to see if they can change the asteroid's path or even break it into pieces.
This mission is more powerful than what NASA did with their DART mission.
China will use a special rocket to send two spacecraft: one to hit the asteroid and another to watch what happens.
The asteroid they are targeting is smaller and stronger than the one NASA hit.
The impact will be very fast, which might make the asteroid break apart.
This is all part of a plan to protect Earth from dangerous space rocks.
China plans to strike Asteroid 2015 XF261 with a spacecraft at 9 km/s (Mach 26).
The mission aims to deflect or potentially shatter the asteroid, going beyond NASA's DART mission.
The target asteroid is 98 feet in size and is believed to be a solid body.
China will use a single rocket to launch both the impactor and observer spacecraft.
The intercept is expected to happen around 2029 or 2030 when the asteroid is 7 million kilometres from Earth.

Mission Objectives
China's Approach
China aims to deflect and potentially shatter the asteroid.
NASA's Approach
NASA's DART mission altered the asteroid's orbit and changed its shape.
Asteroid Target
China's Approach
China targets Asteroid 2015 XF261, a 98-foot solid body.
NASA's Approach
