Jo Ericsson is the astronaut at the center of Constellation — a European Space Agency crew member who returns from a disaster aboard the International Space Station to find that reality itself is subtly, terrifyingly wrong, with details of her life and family inexplicably altered. Disoriented and increasingly desperate, Jo fights to convince others — and herself — that she is not losing her mind.
Her arc is a paranoid psychological thriller that braids space disaster, quantum strangeness, and a mother's fierce love. As Jo unravels the mystery of what happened in orbit and why her world feels off, the series keeps reality flickering between possibilities, using her ordeal to explore grief, identity, and the terror of not being believed.
Noomi Rapace delivers a raw, unnerving performance as a woman adrift between worlds.
