China's mission to retrieve samples from Mars will advance to the flight model development phase within this year.
That is according to Luo Zichong, chief designer of the Tianwen-3 mission, building on the preliminary technical research and demonstrations.
The engineering team is now focused on developing prototypes.
The Mars sample return mission is scheduled for launch around 2028, with the goal of returning no less than 500 grams of Martian samples to Earth by around
2031.
In terms of engineering, The mission is developing an orbiter, a returner, a lander, an ascender,
and a service module which will compose the orbiter-returner complex and the lander-ascender service module complex.
The development work also includes achieving breakthroughs in key technologies such as Martian surface sampling
and sealing, surface takeoff and ascent, Mars orbital rendezvous, sample capture and transfer,
and planetary protection.
The mission is expected to search for potential signs of life on Mars, investigate Martian geological formation
and examine Martian atmosphere, with the objective of making major discoveries in the study of habitable evolution of terrestrial planets.

To optimize the operational status of certain satellites.
The office said that it will continuously strengthen the coordination and testing of in orbit satellites,
as well as monitor and maintain system performance to ensure positive user experience.
As a mature, fully functional and high-performance global satellite navigation system, it currently has 50 operational satellites in orbit.
It achieves a global positioning accuracy of better than 10 meters, velocity measurement accuracy better than 0.2 meters per second.
