Farscape overview:
Astronaut John Crichton assumed he'd be home in time for dinner. But a freak accident during an experimental space mission catapults him across a thousand galaxies to an alien battlefield. Suddenly, he's trapped among alien creatures wielding deadly technology -- a battle that 20th century sci-fi pop culture never prepared him for. Hunted by a merciless military race, Crichton begins his quest for home from a galaxy far, far away.

John Robert Crichton, Jr. is a second generation IASA astronaut with a full doctorate in Theoretical Sciences. He was a popular Mission Specialist on several successful Shuttle missions. His active, take-charge, hero side -- inherited from his father -- has remained untapped until that fateful day when he stepped into his one-man capsule and ended up at the far end of the universe.
Some 30-odd years ago, John Robert Crichton, Jr. was born in North Carolina. His scientist mother was a strong role-model, and he was inspired to study physics, attending MIT and ultimately achieving a doctorate in theoretical sciences. But Crichton was equally inspired by his astronaut father. When the opportunity arose to train with IASA as an astronaut, he jumped at the chance. Because of his strengths as a scientist, he was a valued mission specialist on several shuttle missions.
Despite his astronaut status and tall, classic good looks, Crichton still considers himself just one of the science nerds, like his buddies. Up until recently, his take-charge, heroic nature has remained dormant -- until that fateful day when his experimental, one-man capsule accidentally shot him to the far end of the universe.
Since being hurtled across the galaxy and joining a fugitive crew aboard a living vessel (Moya), Crichton has managed to survive many obstacles, including lethal confrontations with carnivorous and shape shifting aliens. The difficulties he and the alien crew have undergone have forged a special bond between them all. They'll need that bond to survive. The merciless Peacekeepers, a military race, dog their every step, and Crichton in particular is their target.
