Optimal ballistically captured Earth–Moon transfers

Autor: Paul Ricord Griesemer, Cesar A. Ocampo, D. S. Cooley

Publikováno v: Acta Astronautica. 76:1-12

The optimality of a low-energy Earth–Moon transfer terminating in ballistic capture is examined for the first time using primer vector theory. An optimal control problem is formed with the following free variables: the location, time, and magnitude

Autor: D. S. Cooley, Paul Ricord Griesemer, Cesar A. Ocampo

Publikováno v: Journal of Guidance, Control, and Dynamics. 34:893-902

DOI: 10.2514/1.46843 A particular periodic orbit in the Earth–sun circular restricted three-body problem is shown to have the characteristics needed for a ballistic lunar capture transfer. An injection from a circular parking orbit into the periodi

Mission Design for the Lunar CRater Observation and Sensing Satellite (LCROSS)

Autor: K. Berry, G. Marr, Cesar A Ocampo, K. F. Galal, L. Janes, J. Carrico, D. S. Cooley

Publikováno v: AIAA/AAS Astrodynamics Specialist Conference.

The Lunar CRater Observation and Sensing Satellite (LCROSS) was part of a recently completed lunar impactor mission that successfully hit a target crater on October 9, 2009 and discovered the presence of water-ice in a permanently shadowed region of
