The article presents the results of studies on low-energy “detour” transfer trajectories to
an artificial lunar satellite orbit in the Earth-Moon-Sun system for spacecraft launched
from a Russian space canter. In this type of trajectories, the spacecraft (SC) first flies
beyond the Moon’s orbit, out of the Earth’s sphere of influence. Its trajectory parameters
are altered by the Sun’s gravitational perturbations, which enables lunar gravitational
capture of the SC to take place, reducing the delta-V budget of the mission. The SC veloc-
ity is required to be low enough when approaching the Moon’s sphere of influence, which
limits incoming trajectory inclination with respect to the Moon’s geocentric orbit plane.
Therefore, supplementary studies of “detour” trajectories for launches from Russian
space centres are necessary. Calculations conducted in this research confirm the possi-
bility of lunar gravitational capture for SC launched from Russian space centers onto a
“detour” trajectory. In some of the trajectories considered, a gravity assist maneuver
with the Moon is used to increase SC energy and change its orbit inclination.
Keywords:
low-energy detour trajectories, lunar gravitational capture, gravity assist
maneuver.
