Mike was known for doing "swing-bys" to Superdawg with his cousin and partner-in-crime, Steve Bower.
Other applications of this maneuver are available in the literature, like the use of swing-bys to send a spacecraft to the giant planets [11-14] or even to the Sun 15], the use of Venus in a trip to Mars [16,17], the studies to make a three-dimensional close approach to Jupiter to change the orbital plane of the spacecraft [18], the use of the passages by the Moon to increase the energy of the spacecraft [19], and the use of multiple passages by the secondary body to find trajectories linking the primaries or the Lagrangian points [20, 21].
It is important to choose values that are not too low, because that causes too many captures by the Earth, and also those which are not too high, which causes the Swing-Bys to have very few effects on the trajectory of the spacecraft.
If the atmosphere was not present, this type of maneuver would be the standard swing-by described in the references cited previously.
Considering, in some detail, the specific cases, it is clear that the maneuvers where [psi] =0[degrees] and [psi] = 180[degrees] have no change in the energy due to the Swing-By itself.
