ABC has postponed an upcoming drama to give the series time to undergo a creative change. Writing on Deadline.com, Nellie Andreeva reports that production on the limited series “The Astronaut Wives Club,” which was about to go into production for a July 24 premiere, has been postponed until fall.

ABC is now considering a 2014-15 midseason debut for the project, the story reports.

“Originally, the series was envisioned to cover only the wives of the astronauts from the Mercury missions," Andreeva writes. "Now ABC is expanding the scope to also include the Gemini and Apollo missions. That will involve reconceiving the arc of the season and expanding the current cast. Additionally, because the series involves the portrayal of real people, it has to go through an extensive clearing process, which has to be done after the scripts have been written.”

The women who were the focus of the pilot — the seven wives of Mercury astronauts — will remain central characters, the piece notes.

"The current cast includes JoAnna Garcia Swisher as Betty Grissom, Odette Annable as Trudy Cooper, Erin Cummings as Marge Slayton, Zoe Boyle as Jo Schirra, Azure Parsons as Annie Glenn and Desmond Harrington as Alan Shepherd, with casting expected to continue," Andreeva adds.

The project is written by Stephanie Savage, based on the 2013 book "The Astronaut Wives Club," by Lily Koppel.
