The upper spacecraft completes a clockwise rotation every five minutes, whilst the lower vessel turns in the opposite direction, completing a counter-clockwise revolution every ten minutes. Meanwhile, two constantly revolving space stations stage a powerful defense against the effects of gravity.

The mechanism devised by Jean-Marie Schaller is entirely original. Initially deemed impossible, its development required more than three years of research. Given the complexity of the technology involved, the possibility of a successful outcome was even called into doubt after a year's research.
