First sighting of alien spacecraft

While using the Petrovascope to observe the Petrova line around Tau Ceti, Grace notices a strange, intermittent flash of light. He switches to visible light and sees a massive, triangular alien spacecraft, the Blip-A, only a few hundred meters away. The ship is clearly artificial, with smooth, flat surfaces and a design unlike any human spacecraft. This moment of first contact with an intelligent alien species is a profound turning point, shifting the narrative from a solo survival mission to an interspecies collaboration.
