The postponed Sino-Russian cooperative Mars exploration plan will be launched in 20 1 1 year, which will be the first time to comprehensively carry out challenging experiments and research on the radio science of deep space exploration planets. Physics, the core journal of science and technology in China, published a total volume of 38,No. 10 andNo. 1 in June and June 2009, and published 8 articles with the title of "Mars probe firefly1". Among them, 2 papers were written by experts from the Space Science and Application Research Center of the scientific application system undertaking unit, and 6 papers were written by experts from the Shanghai Observatory of the VLBI orbital measurement subsystem undertaking unit. The related research was carried out with the support of the "863" project and the Mars exploration program.

According to experts, "Planetary Radio Science" is the Chinese translation of the English professional vocabulary "Planetary Radio Science" in the field of planetary exploration, and there is no fixed corresponding special vocabulary in Chinese. This technology and scientific research, by measuring the change of high-frequency stable radio wave carrier signal between satellite and ground links or inter-satellite links, accurately determines the orbit of the detector, accurately measures the mass and gravitational field number of the central gravitational celestial body, inverts the gravity field anomaly of the central gravitational celestial body, studies the dynamic characteristics of celestial bodies, detects the parameter profile of atmospheric physical characteristics or solar wind physical characteristics of planetary celestial bodies through occultation, and uses ground frequency or microwave radar to detect the internal structure and ionospheric characteristics of planets. The papers published in this topic cover the above aspects.

In this "firefly 1" exploration mission, the atmospheric occultation detection technology of the link between Mars and China, as well as the satellite-ground link VLBI and one-way open-loop radio independent orbit measurement technology led by Shanghai Observatory researcher Ping Jinsong, have not been used in the deep space exploration mission so far, which constitutes the most critical scientific and engineering technology in the "firefly 1" exploration project.

The promotion and implementation of the "Firefly 1" Mars scientific exploration project marks that China has officially started the process of deep space exploration flying out of earth-moon system, and also marks that planetary radio science has been formally incorporated into the planetary exploration system in China.
