Images of Earth and the moon captured by the Tianwen 2 robotic probe are released on Tuesday by the China National Space Administration.

The samples will be distributed among scientists, who will examine their physical properties, chemical and mineralogical content and isotopic composition, contributing to studies on the formation and evolution of asteroids and the early solar system.

Delivering the samples to Earth will not be the end of the mission. The Tianwen 2 spacecraft will then enter the second phase of its journey, flying toward a main-belt comet called 311P to conduct a remote-sensing survey and transmit the data back to Earth for scientific research, according to the CNSA.

The whole mission is expected to yield ground-breaking discoveries and expand the understanding of Earth and small celestial bodies inside the solar system, scientists said.

The administration said that mission planners aim to accomplish two major engineering goals through the Tianwen 2 project. The first is to develop and demonstrate key technologies needed for gathering sample from weak-gravity celestial bodies, conducting high-precision autonomous navigation and control, and other crucial manoeuvres. The second is to obtain data and samples to facilitate studies on the origins and evolution of asteroids.

Scientifically, planners hope the spacecraft could measure multiple physical parameters of both 2016 HO3 and 311P, covering their size and shape, orbital traits, rotation patterns, and thermal radiation characteristics, allowing for research on their orbital dynamics. Researchers will also analyse their external features, material compositions, internal structures, and potential ejecta.

Rock Samples Return!

China: Chang’e-6 Lunar Module Safely Returns Dark-Side Rock Samples! (26.6.2024)

Lunar samples brought by the earlier Chang’e-5 mission have already drawn applications for access from international scholars, with the process well underway. The Chang’e-6 lunar probe carried four international payloads that were developed jointly by Chinese and foreign scientists. It is conceivable that the openness of Chinese lunar exploration activities will be mirrored in the study of Chang’e-6 lunar samples, said Yang.

The lunar scientific community and the entire humankind are anticipated to reap the rewards of collaborative efforts undertaken by international scientists from a wide range of geographical and disciplinary backgrounds, Yang added.

Zhang Kejian, head of the CNSA, said that exploring the vast universe is a common dream for all of humanity, and only open cooperation is the right path. China’s space endeavors will adhere to the principles of equality and mutual benefit, peaceful utilization, and inclusive development.
