Galileo Observations of Volcanic Plumes on Io
Co-analysis of Galileo imaging observations of the gas and dust components of Io’s plumes suggests that the deposits produced by Prometheus-type plumes are made up of pyroclastic particles that are entrained with the gas flow. Peletype plumes, in contrast, deposit material that could be condensed from the gas phase. Introduction: Many outstanding questions remain to be answered about Io’s spect...
متن کاملSilicate Cooling Model Fits to Galileo NIMS Data of Volcanism on Io
The Near Infrared Mapping Spectrometer (NIMS) has obtained spectra of volcanoes on the surface of the jovian satellite Io. Fits to data using a silicate cooling model allow us to constrain lava eruption rates and eruption age. The thermal signatures of the hot spots are indicative of active and cooling silicate lava flows. For large, active hot spots maximum ages of flow surfaces detected by NI...
متن کاملIo after Galileo
Io, the volcanically active innermost large moon of Jupiter, was a target of intense study during the recently completed NASA Galileo mission to Jupiter (1989–2003). Galileo’s suite of instruments obtained unprecedented observations of Io, including high spatial resolution imaging in the visible and infrared. This paper reviews the insights gained about Io’s surface, atmosphere and space enviro...
متن کاملGalileo imaging of atmospheric emissions from Io.
The Galileo spacecraft has detected diffuse optical emissions from Io in high-resolution images acquired while the satellite was eclipsed by Jupiter. Three distinct components make up Io's visible emissions. Bright blue glows of more than 300 kilorayleighs emanate from volcanic plumes, probably due to electron impact on molecular sulfur dioxide. Weaker red emissions, possibly due to atomic oxyg...
متن کاملCombining Galileo Ssi and Nims Spectra for Europa
Introduction: Prior to spacecraft exploration, ground-based observations of Jupiter's moon Europa revealed that the surface had the spectral signature of water ice [1,2]. Later observations, by the Voyager and Galileo spacecraft, have shown that the surface can be divided up into two main geological and colorimet-ric/spectral units [3]. Most of the surface has a bright, whitish color that is at...
