China successfully launched Tianwen-2 probe at 1:31 a.m. BJ time early Thursday morning from Xichang Satellite Launch Center. The probe is expected to collect samples from the near-Earth asteroid 2016HO3 and explore the main-belt comet 311P. #Tianwen2

(...) The entire mission process is complex. After launch, the spacecraft will journey for about one year to reach its first target, during which it will perform deep-space maneuvers and mid-course corrections until it is about 30,000 km away from 2016HO3.
The probe will gradually approach the target, carrying out close exploration by circling and hovering over the asteroid to determine the sampling area, with a strategy of flying and probing simultaneously.
Given the asteroid's weak gravity, sampling poses unique challenges. A hard surface may result in bouncing back, while a loose surface may cause sinking. The control of the probe must be precise and just right, Han said.
After completing the sampling, the spacecraft will fly back to the vicinity of Earth. A return capsule will separate from the main probe and is expected to deliver the samples to Earth by the end of 2027.
The main probe will then continue its voyage to rendezvous with the more distant target, the main-belt comet 311P, to carry out subsequent exploration tasks. (...)
