2029 mission
[edit]2015 XF261 is the target for an asteroid-deflecting mission planned by China in 2029, launching in 2027, two years after its previous launch target of 2025. Its original target was 2019 VL5. The spacecraft is planned to be launched on a Long March 3B in 2027, making a flyby of Venus before arriving at the asteroid in early 2029, and colliding with the asteroid in April 2029 at an estimated speed of 10 km/s (6.2 mi/s).[4]
