A mysterious signal from deep space leads to humanity's greatest discovery. The crew faces solar storms, decodes alien messages, visits Mars, and finds a habitable exoplanet before returning home as heroes.

The station picks up a repeating signal from beyond the solar system. Mars discovers it's mathematical — prime numbers. Are we alone?

Earth confirms the signal is real. The crew decodes a star map pointing at their location. They must decide what to send back.

The crew is selected for a Mars flyby. Mars the kid is emotional — he's going to his namesake planet. They prepare experiments for the red planet.

A massive solar storm hits on the return from Mars. The crew must ration supplies and shelter in the station's core while Nia keeps spirits up.

The crew identifies a potentially habitable exoplanet and compiles their findings for the world's space agencies. It's their legacy.

The program ends. The crew returns to Earth, reflecting on what they've learned about science, themselves, and each other. Every ending is a new beginning.
