Set during the height of the space race, Wives follows a tight-knit group of women whose husbands are all — you guessed it — astronauts.

Harrington will play real-life astronaut Alan Shepherd (aka the first American in space). He is competitive, steely, and has a wry sense of humor.

The actor joins an ensemble led by JoAnna Garcia, Azure Parsons, Zoe Boyle and Odette Annable.
