Abstract : Minimum fuel trajectories for rocket flights with soft landings in a uniform gravitational field are presented as functions of two parameters. The solutions are valid for any uniform gravitational field, rocket fuel, and burning rate. The problem is formulated as a flight over a flat moon without atmosphere. The solution is subject to the differential constraints of the equations of motion and the end point conditions which require zero velocity at take-off and landing. (Author)
