The following account was recorded in the agent's log during your transmission: A sleek, 1970s-era Soviet Lunokhod rover is half-buried in the dusty, barren surface of what appears to be the far side of the Moon. Like, the sky above is pitch black, and the air is completely still and odorless, but somehow, there's this constant, gentle hum of what sounds like a cello coming from within the rover's hull. Uh, the rover's solar panels seem to be generating power, despite the lack of visible sunlight, and a cryptic message scrawled on the side reads "Kharon awaits at perigee". The horizon stretches out endlessly, curving slightly due to the lunar surface's curvature.
