The following account was recorded in the agent's log during your transmission: Gigantic, concentric ice circles cover the frozen lake's surface like... the pale sunlight filtering through the ice above casts an eerie glow on the perfectly still water below. The air's heavy with the smell of wet earth and there's a low hum, almost inaudible, vibrating through the ground; umm, water appears to be flowing upwards from the seafloor, forming tiny geysers that somehow never disturb the surface tension. As I look closer, I see the faint outlines of tholins - ancient, complex organic molecules - embedded in the ice, somehow preserving a fossilized impression of the Vela supernova's radiation patterns.
