A savage, a scientist, an officer, a rebel, a soldier, a mechanic, and an ex-villainess. All brought together by fate to harness legendary powers and become the Power Rangers. These heroes protect the station Terra Venture on its journey to a new world, and along the way, help anyone in need, and face powerful new foes.

Terra Venture was a perfect simulation of an Earth environment, complete with its own economy, goverment, projection dome, and artifical weather conditions. Command was located at the top of the center dome. Terra Venture was destroyed by Trakeena.
