A photo taken May 3 shows the Mars No 1 base in Jinchang, Northwest China's Gansu province. Based on Jinchang's unique landform which is similar to that of Mars, the base can be used as an experimental base for astronauts to conduct survival training in extra-terrestrial environments and a scenic spot for tourists to experience life on Mars.
