Mars Landing Surveillance Camera for Tianwen-1 Mars Soft Landing Mission
The Tianwen-1 probe, comprising an orbiter, lander and rover, successfully completed the first-ever orbiting, landing and roving on Mars in one single mission.
The outside top surface of the lander platform was equipped with the Mars Landing Surveillance Camera (Mars Camera), which has a wide-angle field of view - to a maximum of 120 degrees horizontally and 170 degrees diagonally. The Mars Camera can withstand the extreme temperature differences on the Martian surface, enabling it to monitor aspects of the operation of the Mars rover "Zhurong", such as the accurate deployment of the solar panels, immediately after landing and before the rover was allowed to move onto the Mars surface.
The Mars Camera has three modes of operation: Still Image, Dynamic Video and Standby. It is lightweight, can withstand huge impact shocks of 6,200G, is equipped with low distortion optics and features a heat-resistant design to ensure imaging quality within the working temperature range on Mars. The camera can withstand extreme low storge temperatures of -70°C and is able to adapt to the ever-changing Martian environmental conditions.
