Man has always observed the canopy of heaven. The planets and the stars, which are always above his head, have stimulated man’s imagination and aroused in him the desire to reach them. Soon, he dreamt at night that he “had found the secret of freeing himself from the laws of gravity, so that his body, having become indifferent to ascending of descending, could do one or the other with equal ease and according to his will”, Brillat-Savarin tells us. This dreamlike flight, mobilized by a light impulse, is the very impression of a pure leap, of an impulse forever suspended. The Humans then become, through his dream, a light and floating being, thus rediscovering the maternal matrix. But our desire to fly, as old as humanity, nevertheless requires a surpassing of the body, which alone struggles to rise. But how do we solve this problem of the mechanics of flight? How can we find the dynamics that allow us to free ourselves from the laws of gravity? This search, which up to now has been purely visual, gradually turned into a physical project. In order to reach these extreme altitudes, man had to ensure that the centrifugal force and the earth’s attraction were exactly balanced. In order to ensure that the chosen vehicle receives a mathematically exact impulse, man had recourse to the old celestial mechanics. Thus was born the science of astronautics, which is capable of predicting the trajectory and speed of any projectile. Journeys outside our atmosphere then took shape, v=but where they to go? This flight towards the sky will make us imagine with envy the flight of astronauts in weightlessness, thus becoming revealing agents of this underlying dream. With Celestial Mechanics, I lake myself the vessel of an imaginary journey, transporting us to the farthest reaches of the world, a journey through the history of propulsion mechanics and into the vacuum of space. Thus reminding us that the imaginary was and will very often be the ideal vehicle for the simulation of scholarly proposals. I would like to thank the Cité de l’Espace and ISAE SUPAERO, and more particularly Serge Gracieux and Laurent Joly, who took the time to enrich my research and to feed my imagination through discussions, readings and laboratory visits.

Manon Lanjouère

I consider Manon Lanjouère like an open space, an interrogative power, and the desire not to close questions. Her heuristic process, finding by groping, and inventing herself as a tightrope walker on the horizon, int the bricolage of the composite. In the night of space, there are no more boundaries, it is a vertical dive into the void, the nothingness, the infinite amniotic...
