Gwyneth Lewis and Joe Tanner are cousins - she is a poet and he is a Nasa astronaut. In 1997
Joe's second shuttle mission gave Gwyneth the inspiration for her acclaimed poem Zero Gravity. Now as Joe returns to space as part of the team building the international space station, Gwyneth travels to Florida to witness the launch and to explore the themes of the poem -the physical and spiritual journeys we all make.
