China News Service, Beijing, August 17 (Ma Shuaisha) A reporter learned from the China National Space Administration on the 17th that as of August 15, the "Zhu Rong" rover was operating on the surface of Mars for 90 Martian days (about 92 Earth days). ), a total of 889 meters traveled, all scientific payloads were turned on for detection, and a total of about 10GB of raw data were obtained. The "Zhurong" rover successfully completed the scheduled inspection mission.

  At present, the "Zhurong" rover is in good condition, stable on foot, and with sufficient energy. In the future, it will continue to drive to the ancient land-sea junction in the southern Utopia Plain to implement expansion missions.

  During the inspection and exploration period, the "Zhu Rong" rover operated in an efficient detection mode of "a cycle of seven days, a plan per day, and detection every day".

The navigation terrain camera acquires terrain and landform data along the way, supports the path planning of the rover and the selection of detection targets, and is used to carry out the research on the topography and geological structure.

  The subsurface detection radar obtains the subsurface layered structure data for the analysis of the shallow surface layer structure and explores the possible existence of ground water ice; the meteorological measuring instrument obtains the temperature, pressure, wind speed, wind direction and other meteorological data, which is used to carry out the research of atmospheric physical characteristics; The surface magnetic field detector obtains local magnetic field data, and cooperates with the orbiter magnetometer to explore the evolution process of the Martian magnetic field; the surface composition detector, multi-spectral camera obtains the spectral data of specific rocks, soil and other typical targets for element and mineral composition, etc. Analysis.

  7 scientific load acquisitions including terrain camera, surface composition detector, subsurface detection radar, meteorological measuring instrument, orbiter high-resolution camera, subsurface detection radar (very low frequency mode), ion and neutral particle analyzer, etc. Related processing and quality verification of the data have been completed, and standard data products have been formed. The China Lunar and Deep Space Exploration Network has opened data applications to domestic scientific research teams a few days ago. In the future, scientific data will be released in batches on a monthly basis.

  At present, the orbiter is operating in the relay communication orbit, mainly for the "Zhu Rong" Mars rover for relay communication.

From mid-September to late October 2021, Mars and the earth will travel to both sides of the sun, and the three will be almost in a straight line, that is, solar transit will occur. Due to the influence of solar electromagnetic radiation interference, the communication between the device and the earth will be interrupted. In 50 days, the orbiter and the Mars rover will switch to safe mode and stop the exploration work.

  After the solar transit, the orbiter will select the opportunity to enter the remote sensing mission orbit to carry out global remote sensing exploration of Mars to obtain scientific data such as Mars morphology and geological structure, surface material composition and soil type distribution, atmospheric ionosphere, and Martian space environment, while taking into account Mars Relay communication in the vehicle development mission phase.
