On October 22, the "Tianwen-1" orbiter and the "Zhurong" Mars rover passed the first solar transit safely and resumed scientific exploration.
The earth and Mars move to both sides of the sun and the three are almost in a straight line. This phenomenon is called solar transit.
During this period, the communication between the Mars rover and the earth was disturbed by the sun's electromagnetic radiation, which was unstable or even interrupted.
The "lost connection" between the probe and the ground during the solar transit is the expected normal state, and the "lost connection" is not "missing".
During the transit period, the "Tianwen-1" orbiter and the "Zhurong" Mars rover entered autonomous operation mode and suspended scientific exploration work.
In order to find out the actual impact of Riling, the engineering development team continued to carry out measurement and control link tracking tests, and for the first time obtained measured data on the interference of deep-space measurement and control communications under Riling, and accumulated first-hand data and engineering experience for subsequent tasks to deal with Riling.
A few days ago, the solar transit phenomenon has ended, and the measurement and control communication between the probe and the earth has returned to normal. According to the telemetry data, the "Tianwen No. 1" is in normal condition during the solar transit.
Riling can be said to be a "frequent visitor" in space activities.
Space activities such as manned spaceflight and lunar exploration projects have also been affected many times by the sun.
However, the transit of Mars this time is the longest encounter in China's previous space activities.
