Mars surface mineralogy from Hubble Space Telescope imaging during 1994-1995: Observations, calibration, and initial results
Bell, James F.; Wolff, Michael J.; Clancy, R. Todd +3 more
Visible to near-infrared observations of Mars were made with the Hubble Space Telescope (HST) during 1994-1995 with the goals of monitoring seasonal variability of the surface and atmosphere and mapping specific spectral units to constrain the planet's surface mineralogy. This paper presents the details of the collection and calibration of the dat…
1995 observations of Martian dust storms using the Hubble Space Telescope
Bell, James F., III; Wolff, Michael J.; Clancy, R. Todd +3 more
A synoptic monitoring program of Mars using the Wide Field Planetary Camera 2 on board the Hubble Space Telescope has resulted in the observation of discrete dust activity for two dates following the 1995 opposition. Data obtained on April 8 (LS=82°) and August 21, 1995 (LS=145°) reveal the presence of local dust storms in th…
Comparison of IUE and HST diagnostics of the Jovian Aurorae
Livengood, T.; Harris, W. M.; Prangé, R. +2 more
Analysis of international ultraviolet explorer (IUE) and Voyager ultraviolet spectrometer (UVS) spectra of the Jovian auroral emission indicates that the Jovian auroral brightness is modulated in longitude (brighter near 180° in the north and 20° in the south) and that there is a color ratio asymmetry associated with this brightening. The purpose …
