Grey Sloan Memorial's loss is Extant's gain. Tessa Ferrer has joined the cast of CBS's Halle Berry-fronted summer series, TVGuide.com has confirmed.

Executive-produced by Steven Spielberg, the mystery thriller stars Berry as an astronaut who returns from a year-long journey in space and attempts to reconnect with her husband (Goran Visnjic) and android son. Ferrer will recur as Katie Sparks, an over-achieving astronaut and the daughter of Michael O'Neill's Alan Sparks, who serves as the director of the ISEA.

Extant premieres Wednesday, July 9 at 9/8c on CBS.
