Optimization of satellite constellations in the moon
(2010-12-01)
Nowadays, we return to live a period of lunar exploration. China, Japan and India heavily invest in missions to the moon, and then try to implement manned bases on this satellite. These bases must be installed in polar ...

Alternative paths for insertion of probes into high inclination lunar orbits
(Elsevier B.V., 2007-01-01)
The dynamics of the restricted three-body Earth-Moon-particle problem predicts the existence of direct periodic orbits around the Lagrangian equilibrium point L1. From these orbits, we derive a set of trajectories that ...
Half a century after the first bootprint on the lunar surface: the ichnological side of the Moon
(Elsevier, 2021-01)
Humankind began with extra-planetary expeditions in the 1960s. To date, more than fifty manned and unmanned lunar missions have taken place. Maybe, the most iconic image of these campaigns is the bootprint left and ...

A permanent magnet hall thruster for pulsed orbit control of lunar polar satellites
(2014-01-01)
Future Moon missions devoted to Lunar surface remote sensing, for example, will require very fine and accurate orbit control. It is well known that Lunar satellites in polar orbits will suffer a high increase on the ...
Strategies for plane change of Earth orbits using lunar gravity and derived trajectories of family G
(Springer, 2009-04-01)
The dynamics of the circular restricted three-body Earth-Moon-particle problem predicts the existence of the retrograde periodic orbits around the Lagrangian equilibrium point L1. Such orbits belong to the so-called family ...
