متن کاملSolving the mystery of Iapetus
Since the discovery of Iapetus by G. D. Cassini, in 1672, it has been known that the leading hemisphere of this Saturnian satellite is one order of magnitude darker than the trailing hemisphere. Since the Cassini spacecraft entered the Saturnian orbit, several high-quality images of the dark hemisphere of Iapetus have been obtained, in particular during the Dec 31 2004 flyby of this satellite. ...
متن کاملHyperion Correction
Two Hyperion images of the Greenland ice sheet are used to characterize errors in the VNIR and SWIR detector arrays of Hyperion. Spatial variability in detector output is seen in both arrays and, in both cases, is largest at the shorter wavelengths and decreases as wavelength increases. Standard deviations of the maximum variability are 40 DN for the VNIR array and 123 DN for the SWIR array. Te...
متن کاملLuminous Phenomena of Earthquakes: Observations and Theories
Over the past few years, different theories (piezoelectric, positive holes, friction-vaporization, exo-electron emission, tribo- or fracture electrification) have been presented for the interpretation of earthquake lights. Although these theories can interpret earthquake luminous, each suffer from particular problems. There are also ambiguities and questions about the location of the light, the...
متن کاملThe Chaotic Rotation of Hyperion
A plot of spin rate versus orientation when Hyperion is at the pericenter of its orbit (surface of section) reveals a large chaotic zone surrounding the synchronous spin-orbit state of Hyperion, if the satellite is assumed to be rotating about a principal axis which is normal to its orbit plane. This means that Hyperion's rotation in this zone exhibits large, essentially random variations on a ...
