The Antares crew launches into space, on "Defying Gravity," SUNDAY, AUGUST 2 (9:00-11:00 p.m., ET) on the ABC Television Network. In the first hour, "Pilot" (9:00-10:00 p.m.), a team of eight astronauts, embarking on a six-year journey to explore Venus and other planets in the solar system, find their lives and destinies intertwined and carefully directed, not only by Mission Control officials on Earth, but also by an unseen force which is much closer and far more powerful.

"Pilot" was directed by David Straiton and written by James Parriott.
