Designing 3D transfers: application to Earth-Moon

Allan Kardec de Almeida Junior, Timothée Vaillant, João P. F. Agostinho +2

Three dimensional Earth-Moon transfers usually consume more fuel than planar ones, but are needed depending on the latitude of the launch site and the desired inclination of the fi…

Analytical modeling of the gravitational potential of irregularly shaped celestial bodies considering three distinct internal structures: application to (21) Lutetia

Marcelo L. Mota, Safwan A., Antonio F. B. A. Prado

The classical polyhedral model is one of the most accurate methods currently used to represent the gravitational field of irregularly shaped bodies. However, it assumes a homogeneo…

Potential series expansion method applied in Analytical Modeling of Gravitational field of Irregularly Shaped Celestial Bodies

Marcelo Lisboa Mota, Safwan Aljbaae, Antonio F. B. A. Prado

This study aims to establish an analytical model that reproduces the gravitational field around non-spherical bodies with constant density. Due to the non-spherical geometry of suc…
