 Kenneth MitchellJericho grad Kenneth Mitchell has boarded ABC’s upcoming period drama The Astronaut Wives Club, TVLine has learned exclusively.

Mitchell will play Wisconsin farm boy and WWII flyer Deke Slayton, one of the original Mercury Seven astronauts. When a medical condition prevents him from going into space, he becomes a powerful voice in the space program.

ABC recently decided to hold the period drama — originally scheduled to bow this July – until midway through the 2014-2015 season to give Savage and fellow EP Josh Schwartz time to expand the premise. (The action originally centered on the wives of the Mercury astronauts; it will now more closely follow Lily Koppel’s 2013 bestseller and chronicle the lives of the Gemini and Apollo mission crews’ spouses, as well.)

Mitchell, who’s currently recurring on ABC Family’s Switched at Birth, joins a cast that includes JoAnna Garcia Swisher (Once Upon a Time), Odette Annable (House) and Desmond Harrington (Dexter).
