Probing the Flyby Anomaly with the Galileo Constellation [PDF]
arXiv, 2011 In the last few years, the so-called flyby anomaly has been widely discussed, but remains still an illusive topic. This is due to the harsh conditions experienced during an Earth flyby as well as due to the limited data available. In this work, we assess the possibility of confirming and characterizing this anomaly by resorting to the scientific ...

Journal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.Abstract The prospect that the five major moons of Uranus could host subsurface oceans makes them high‐priority targets for future exploration. Different techniques can be used to search for deep oceans in these objects. Here, we focus on ocean detection and characterization from measurements of the moons' response to the gravitational tides and ...

Raffaello Caverni (1837 - 1900) and the Society for the progress of the sciences: an independent priest criticized by the lay scientists [PDF]
arXiv, 2012 Raffaello Caverni, a Catholic priest, was a truly lay and anti-establishment intellectual in his opinions both on Darwin and on Galileo. He opposed the mythicization of Galileo, as a rule in Italy after the unification, even though he considered Galileo a great scientist.

Galileo internal electrostatic discharge program [PDF]
, 1985 The Galileo spacecraft which will orbit Jupiter in 1988 will encounter a very harsh environment of energetic electrons. These electrons will have sufficient energy to penetrate the spacecraft shielding, consequently depositing charges in the dielectric ...

A Search for the Near‐Surface Particulate Layer Using Venera 13 In Situ Spectroscopic Observations
Journal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.Abstract Whether or not there is a particulate layer in the lowest 10 km of the Venusian atmosphere is still an open question. Some of the past in situ experiments showed the presence of a detached particulate layer, and a few suggested the existence of finely dispersed aerosols, while other instruments supported the idea of no particulate matter in ...

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 4, April 2025.Abstract The Global Navigation Satellite System (GNSS) airborne radio occultation (ARO) technique is used to retrieve profiles of the atmosphere during reconnaissance missions for atmospheric rivers (ARs) on the west coast of the United States. The measurements of refractive bending angle integrate the effects of variations in refractive index over ...
