Part 2 of 3. This new Syfy miniseries imagines a 100-year space voyage from Earth to some unpopulated but hospitable planet, and picks up the drama at the halfway point, 51 years in. By coincidence, tonight’s episode, the second of three parts, marks the halfway point as well – and if you watched last night, I’m betting you’re sticking around for the rest of the trip.
