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.
