UV auroras in projections on the ionosphere of Io, Europe and Ganymede occur almost permanently, while the observation of the track of Callisto is difficult. One of the reasons is that the Callisto projection lies near or inside Jupiter's bright main oval. Another reason is that Callisto is ...
Beyond about 10RJfrom Jupiter the configuration of magnetic field lines in Jupiter's magnetosphere is strongly affected by the presence of an equatorial cu... RB Mckibben,JEP Connerney - 《Journal of Geophysical Research Biogeosciences》 被引量: 0发表: 1986年 High fidelity? Deception and seducti...
The peak electron density indicated by the upper hybrid resonance emission was 400 cm 3 , almost one-thousand times the electron density in the magnetosphere of Jupiter at the orbit of Callisto. These observations indicate that Callisto is probably surrounded by a dense ionospheric-like plasma. ...
The discovery had not only astronomical, but also religious implications. At the time, the Catholic Church supported the idea that everything orbited the Earth, an idea put forth in ancient times by Aristotle and Ptolemy. Galileo's observations of Jupiter's moons — as well as noticing that ...
research. In addition to the possibility of a subsurface ocean, this moon is the only Galilean far enough outside of Jupiter’s powerful magnetosphere that it does not experience harmful levels of radiation. This, and the prospect of finding life, make Callisto a prime candidate for future ...
These moons orbit within the giant magnetospheres of their respective host planets, and thus the presence of O3 on their surfaces is the result of its abiotic synthesis: the irradiation of oxygen-rich surface ices liberates atomic oxygen, which in turn may yield molecular oxygen (O2) and then...
In the vicinity of Callisto, PEP will characterize the plasma environment, the outer parts of Callisto's atmosphere and ionosphere and their interaction with Jupiter's dynamic magnetosphere. Roughly 20 Callisto flybys with closest approaches between 200 and 5,000 km altitude are planned over the ...
with the Jovian magnetosphere, which drives ~1.5×10A through Callisto's highly conducting (~10mho) ionosphere and generates a highly reduced ionospheric electric field, severely retarded ionospheric convection (~0.1 km s), and a factor of ~1500 reduction in the net electron impact emission rate....
Callisto orbits too far away from Jupiter to be effected by the giant planets’ magnetosphere, which means that Callisto is not subject to the tidal friction, orbital, and rotational energy that causes the surfaces of the other moons, such asEuropa, to be heated to the point where surface ic...
Depth Dose Exposures in the Magnetosphere of Jupiter at the Icy Moons:Callisto,Ganymede,and EuropaThe highly successful Galileo mission made a number of startling and remarkable discoveries during its eight-year tour in the harsh Jupiter radiation environment.Two of these revelations were:1) salty ...
