Zachary actress Abbie Gayle will guest-star on “The Astronaut Wives Club” on Thursday and Aug. 6.

Gayle, 18, will play Alice Shepard, one of NASA Mercury 7 astronaut Alan Shepard and Louise Shepard’s three daughters.

In Thursday’s episode, “Rendezvous,” the Gemini missions are being successfully launched and the Apollo program kicks into high gear. The pressure on the wives mounts and tragically some of the women become the first space widows. That theme continues in the Aug. 6. episode, “Abort,” in which Betty Grissom faces the loss of her husband, Gus, who dies while preparing for a NASA mission.

Gayle was recently seen as Abbie in the New Orleans-shot ABC Family series “Ravenswood,” and has done several TV commercials.
