Chinese Scientists Call For Focus On Asteroid Missions

HELSINKI — China should intensify its asteroid research and focus on sample return mission plans, according to scientists.

China’s future asteroid exploration should focus on "low-cost, high-frequency sample return missions, and emphasize strengthening coordination between missions," according to a paper published recently in the Chinese Journal of Space Sciences. Establishing scientific design teams can also help better serve China's future asteroid explorations.

China is scheduled to launch its first asteroid sample return mission in 2025. The Tianwen-2 mission will target near-Earth object (NEO) 469219 Kamoʻoalewa, collecting samples and returning to Earth around 2.5 years after launch. The mission will notably harness both a touch-and-go technique used by both NASA's OSIRIS-REx and JAXA's Hayabusa2, and an anchor-and-attach system featuring drills at the tips of landing legs.
