Mars Exploration : Zhurong announced to enter "winter dormancy" mode in case of strong sand and dust weather

On 20 May, the National Space Agency (NASA) and the Space Engineering Centre noted that, in response to the reduced solar wing power capacity and extremely low environmental temperatures caused by sandy weather and winter, the Mars vehicle was transferred to dormant mode on 18 May, in accordance with the design and flight control strategy.
As part of the Mars Patrol of the Mars mission "Christmas One", the Rover has been operating on the surface of Mars. A medium-resolution image of the Rover that was taken by Mission One before the day was discovered that the Rover was undergoing a clear sandstorm.
Scientists compared the typical geomorphology (especially on the edge of the crash pit) in the 120m resolution image of the Convergence cruise area of 16 March and 30 April 2022 with changes in solar-wing electrical currents, as reflected in recent Mars vehicle telemetry information, to determine that the field is experiencing strong sandy weather. On May 6, observation reports indicated that the area in which the Rover was located had entered winter, that the maximum temperature of the RV had been reduced to 20°C at noon, that the night environment was low to below -100°C, that by mid-July the temperature would have fallen further before and after the mid-July winter, and that sand and dust weather had further reduced light intensity, affecting the capacity of the RMS solar-wing battery. It is reported that Mars is similar to the Earth, and after winter, the northern hemisphere is experiencing a decline in the Sun-lighted high angles and a reduction in light-time. The engineering team has recently implemented a energy balance by shifting the solar wing to a light-based angle, reducing the number and duration of daily work.
According to the National Space Agency (NASA) Center for Exploration and Space Engineering, it is expected that after December of this year, the Melon cruise area will enter the first spring and that the environmental conditions will return to normal work. Question No. 1 is implementing a remote sensing survey of the global coverage of Mars, where the former imaging area is mainly concentrated in the high altitude of the southern hemisphere of Mars. The mission team will continue to monitor the weather as far as possible using the loop.
