ASTEROID SAMPLE

China plans to launch the Tianwen-2 mission around 2025 to collect samples from a near-Earth asteroid and explore a comet, a senior space expert said Monday.

The main goal of the Tianwen-2 mission is to send a probe to a near-Earth asteroid coded 2016HO3 to retrieve samples, Zhang Rongqiao, the chief designer of China’s planetary exploration program and chief designer of the Tianwen-2 mission, told the media on the country’s Space Day that falls on April 24.
