Astronauts on Mars, wearing space helmets and spacesuits, appear slightly invisible. He stepped on the red desert, with a vast and boundless Martian plain in the background, filled with red rocks and dust in his field of vision. The sun shines brightly through the thin atmosphere, illuminating Mars and creating a magnificent scene in space. The figure of the astronaut walks alone on this desolate planet, with the endless darkness of the universe behind him. This photo captures an atmosphere of loneliness, grandeur, and infinite possibilities, immersing people in it and triggering countless thoughts and imaginations about the universe. --auto
