China's Tianwen-2 space probe has reached its asteroid target after a journey of 1 billion kilometers (620 million miles) that took more than a year, the Chinese space agency announced Monday. The milestone marks the arrival phase for the nation's first attempt to retrieve samples from an asteroid.
The mission positions China alongside the United States and Japan in the elite club of nations capable of asteroid sample collection. Success would provide scientists with pristine material from the early solar system, potentially offering clues about planetary formation and the origins of life.
The probe traveled the equivalent of over 620 million miles to rendezvous with its target. The Chinese space agency confirmed the spacecraft's arrival but did not immediately disclose details about the sampling timeline or the asteroid's specific characteristics.
Tianwen-2 is now expected to begin surveying its target before attempting to collect surface material. A successful sample return would represent a significant technical achievement, requiring the craft to navigate, land on, and lift off from the asteroid's surface.
The mission builds on China's growing deep-space capabilities, following its lunar sample return efforts and Mars orbiter-rover combination. No timeline has been given for the sample's return to Earth.
