China News Service, Beijing, November 8. According to the China National Space Administration, on November 8, the "Tianwen-1" orbiter successfully implemented the fifth near-fire brake, accurately entered the orbit of the remote sensing mission, and carried out the global remote sensing exploration of Mars. , Will obtain scientific data such as Martian morphology and geological structure, and Martian space environment, focusing on typical landforms and geological units such as craters and volcanoes.
In the early stage, the "Zhu Rong" Mars rover has completed the established patrol and detection mission objectives, and is in good condition, and continues to carry out the detection mission.
Considering the global remote sensing detection of the orbiter and the relay communication requirements of the Mars rover, the engineering development team optimized the orbit design and determined a remote sensing orbit plan with a near fire point of about 265 kilometers, a far fire point of about 10,700 kilometers, and a period of about 7.08 hours. While ensuring the development of orbiting scientific exploration, it will provide more relay communication support for the Mars rover to improve mission efficiency.
In the remote sensing orbit, seven scientific payloads including mid-resolution cameras, high-resolution cameras, subsurface detection radars, mineral spectrum analyzers, magnetometers, ion and neutral particle analyzers, and energy particle analyzers will be acquired Scientific data such as fire star morphology and geological structure, surface material composition and soil type distribution, atmospheric ionosphere, Martian space environment, etc., focusing on typical landforms and geological units such as craters, volcanoes, canyons, and dry river beds, and implement high-resolution detection.
Up to now, the "Tianwen-1" orbiter has been in orbit for 473 days, with a ground-fire distance of 384 million kilometers, and its travel time is 21 minutes and 20 seconds; the "Zhu Rong" rover has worked on the surface of Mars for 174 Mars days, accumulatively traveling 1,253 meters, the two devices are in good condition, and the working conditions of each system are normal.
