This Space Available, By Emily Carney. A previous installment of This Space Available discussed Dr. Brian O’Leary’s ubiquity in op-eds and media before and after the publication of his 1970 memoir, The Making of an Ex-Astronaut. While there is not enough space in a blog format to discuss Dr. Gerard K. O’Neill’s pop culture presence throughout the 1970s – indeed, he rose to a level of fame enjoyed by another working scientist from that era, Dr. Carl Sagan – we’ll discuss selected appearances from television shows and in print.
