October 2011's Space Babe is Sigourney Weaver as Warrant Officer Ripley in director Ridley Scott's 1979 sci-fi Gothic, Alien. As portrayed by the then-relative newcomer, the strong-willed Ripley proved to be the ultimate survivor, not only escaping from the clutches of the titular extraterrestrial xenomorph, but going on to thwart its toothy brethren in three sequels. Of course, most of us here at Space: 1970 remember her primarily for her scanty panties at the original film's conclusion. Shame on us.

Born as Susan Weaver, the tall, striking brunette has appeared in a number of genre films, but has also garnered considerable acclaim as a serious dramatic actress. Among her sci-fi/fantasy credits are the aforementioned Alien franchise sequels, the Ghostbusters films, James Cameron's Avatar, Paul, and the delightful spoof, Galaxy Quest, which poked good natured fun at the kinds of TV shows we celebrate here at Space: 1970.
