China is ready to launch the Tianwen-1 Mars rover, which includes an orbiter, a lander and a rover. It also has four giant "wings" – solar panels to provide power for it. The rover can adjust the angles of its solar panels to receive more solar power, according to Liu Tongjie, deputy director of the Moon Exploration and Space Engineering Center of the China National Space Administration. "As Mars receives less solar energy than the Earth and the Moon, the area [of its solar panels] is larger. It can angle its solar panels according to the direction of the sunlight.
