Professor Yung Kai-leung of the Hong Kong Polytechnic University (PolyU) shows the Mars Landing Surveillance Camera, developed by his university team in cooperation with the China Academy of Space Technology. The camera monitored the landing of Tianwen 1 and took images of the surrounding environment on the Mars surface. The Mars Camera weighs only 390 g but is strong and durable enough to withstand the extreme temperature differences of about 150oC experienced during the 9-month journey between Earth and Mars, and an impact shock of 6,200 G.
