Our previous analyses of radio Doppler and ranging data from distant spacecraft in the solar system indicated that an apparent anomalous acceleration is acting on Pioneer 10 and 11, with a magnitude aP ∼ 8 × 10 −8 cm/s 2 , directed towards the Sun. Much effort has been expended looking for possible systematic origins of the residuals, but none has been found. A detailed investigation of effects both external to and internal to the spacecraft, as well as those due to modeling and computational techniques, is provided. We also discuss the methods, theoretical models, and experimental techniques used to detect and study small forces acting on interplanetary spacecraft. These include the methods of radio Doppler data collection, data editing, and data reduction.There is now further data for the Pioneer 10 orbit determination.

“…The smaller body that is passing by the larger one is accelerated or braked by the gravity field of the celestial body and so its trajectory is modified. Successful missions, such as Voyager 1 and 2 [7], showed the efficiency of the swing-by in saving fuel. An example of the use of this maneuver to change the orbital inclination of a spacecraft is the Ulysses mission, presented in [8], where the spacecraft was placed in a near polar orbit around the Sun, in order to observe the poles of the Sun.…”

Abstract. This paper has the goal of showing some cases of plane change maneuvers using a swing-by with the Moon to decrease the magnitude of the impulses used, when compared to a classical Hohmann maneuver. The analytical model is based on the "patched-conics" approach, where a series of "two-body" problems is considered to build the whole maneuver. A study of the effects of the semi-major axes of the transfer orbits were made, to complete some previous studies made in the literature. The results show that, for some final inclinations, the use of the swing-by in the Moon is really advantageous.
