July's Space Babe is pretty Jean-Marie Hon, who co-starred in two Space: 1970 favorites: Ark II and Man From Atlantis. On the Saturday morning Filmation series, Ark II, Jean-Marie portrayed the youthful and idealistic scientist Ruth, who traveled a post-Holocaust America with her equally-idealistic companions Jonah, Samuel, and talking chimp, Adam, bringing technological and humanitarian aid to the scattered remnants of civilization. On Man From Atlantis, she was Jane, communications officer aboard the advanced research submarine, Cetacean, providing back-up support for aqua-mariner Mark Harris's undersea adventures.
I've been able to find out very little about the lovely Ms Hon online. She was born in 1955 in San Francisco, and acted on television from 1976 (Ark II) through 1985, appearing in TV movies and in guest shots on shows like Hawaii 5-0 and The Hardy Boys. According to what little I've been able to uncover in my Internet safaris, she retired from acting to raise a family and became a pharmacist. She appeared in the supplemental interview material on the Ark II DVD set from BCI a few years back, and still looked beautiful.
