“The boundary between science fiction and social reality is an optical illusion” (149). So Donna Haraway wrote in 1985 in “A Cyborg Manifesto.” When I composed a call for papers around this evocative line, I hoped to solicit work that would address the continuities and the transformations between the chimeric time of Haraway’s 1980s and our own uneven present, more than 20 years on. The response was successful beyond my wildest hopes. Feminist science fiction, in the collective analysis of the writers gathered here, proves to be a diverse and amorphous category in which real and imagined science and technology bleed into one another. The essays call attention to the ways in which fictions and realities of scientific speculation shape how we experience the nexus of gender, new media, and technology––from the gendered history of physics to the migration of brain-scanning technology out of laboratories and into the world, from imagined visions of reproductive technologies to sentient robots to the social consequences of cataclysmic change in urban landscapes.
