China's Mars sample return mission aims to gather certain samples from the Red Planet, Mars and then deliver them to Earth in 2031, or 2 years earlier than the NASA and ESA joint mission, stated by a media report.

According to SpaceNews report, Sun Zezhou the chief designer of the Tianwen-1 Mars orbiter and rover mission has mentioned in one of the report that China has been planning for a two-launch profile. Well, this launch is expected to get lifted off in late 2028 and later the samples would get delivered to the Earth may be by July 2031.

China's sample return mission was initially disclosed during a report which was released in January. The released report has mentioned the country's ambitious space exploration plans for the next coming 5 years.

It have been noticed that the advanced, multi-launch mission will be having simple uncomplicated design as compared with the joint NASA-ESA project. The mission will be having one Mars landing with no rovers sampling at completely different sites, as per the report statement.

According to the same report it has been notified that the mission, named Tianwen-3, will be consisting of two different combinations. One of the combinations include a lander and ascent vehicle and the other includes an orbiter and return module. Hence the combinations will be launching one by one first on Long March 5 and the other on Long March 3B rockets respectively.

Well the landing on Mars is expected to take place in around September 2029. The sampling techniques through which it becomes easier to collect the sample would be including surface sampling, drilling and mobile intelligent sampling, by using a four-legged robot.

Zezhou has added in his statement that the Tianwen-1 orbiter will be conducting the aero-braking test in Mars orbit later this year. This aero-braking test is considered as a part of the sample return mission preparation, stated in a report.
