Star Trek Expanded Universe

Dr. Samantha Delaney was a Federation scientist, who, with her husband Dr. Henrik Delaney, created a folded space drive prototype.

In 2371, Henrik Delaney installed their folded space drive prototype aboard the USS Rutherford and accompanied the crew on testing the device. Initial tests were successful until 2372, when the device malfunctioned, and the Rutherford jumped from the Alpha Quadrant to the Gamma Quadrant.

In an attempt to protect the device from falling into Dominion hands, Henrik Delaney triggered the device aboard a shuttlecraft on New Bajor. (Star Trek: The Prospect Chronicles: "Directive")

Henrik's disappearance, months after the disappearance of their twin daughters Megan and Jenny aboard the USS Voyager, drove Samantha Delaney to despair ; her work on perfecting the folded space drive kept her sane.

Her work, however, was destroyed by undercover Na'arbi agent Hahn Jun-Seok, and this action drove her insane.

Working aboard Dante Station, Samantha Delaney constructed two more prototypes, secretly hard-wiring one into the station's frame and another aboard her cloaked ship in the station's orbit. (Star Trek: The Cantabrian Expeditions: "An Innocent Time")
