AbstractTrajectory corrections for lunar flyby transfers to Sun-Earth/Moon libration point orbits (LPOs) with continuous thrusts are investigated using an ephemeris model.  ...  Using a prograde type 2 orbit as an example, numerical simulations show that our control strategy can efficiently address trajectory corrections for lunar flyby transfers with different practical constraints  ...  The data of the spacecraft and thrust engine are listed in Table 1 Lunar flyby transfers to libration point orbits In this paper, lunar flyby transfers from an LEO at an altitude of 200 km to Sun-Earth  ...

Use of Libration-Point Orbits for Space Observatories

Robert W. Farquhar, David W. Dunham
1990 International Astronomical Union Colloquium  
AbstractThe Sun-Earth libration points, L1and L2, are located 1.5 million kilometers from the Earth towards and away from the Sun.  ...  Halo orbits about these points have significant advantages for space observatories in terms of viewing geometry, thermal and radiation environment, and delta-V expediture.  ...  These transfers utilize a powered close lunar swingby to decrease the libration-point insertion costs. Figure 3 is like T h e delta-V is largest to achieve an orbit of about 100,000-km.  ...
