Draw a lunar base with a futuristic saucer-shaped spacecraft arriving and departing. The underground base is constructed using a crater, and a passenger terminal made of glass is installed on the surface. Inside the terminal, a holographic display shows schedules and destinations, which are confirmed by people passing by. The floor is decorated with LED lines designed to look like flowing energy, and the overall atmosphere is high-tech and futuristic. Autonomous robots load passengers' luggage at the terminal, and small guided drones safely guide the spacecraft through the departure and arrival areas. The saucer-shaped spacecraft is docked, its smooth metal body and blue energy engines gleaming. Human presence is limited to the glass-fronted building, which is protected from outer space. Outside the terminal, communications towers shine neon lights on the moon's surface, and in the distance, undulating craters and rocky outcrops stretch out. The blue Earth shines beautifully in the night sky, representing a spectacular lunar base in the near future.
