Mars Reconnaissance Orbiter's High Resolution Imaging Science Experiment (HiRISE)
[1] The HiRISE camera features a 0.5 m diameter primary mirror, 12 m effective focal length, and a focal plane system that can acquire images containing up to 28 Gb (gigabits) of data in as little asExpand
Cassini Observes the Active South Pole of Enceladus
Cassini has identified a geologically active province at the south pole of Saturn's moon Enceladus. In images acquired by the Imaging Science Subsystem (ISS), this region is circumscribed by a chainExpand
In Situ Evidence for an Ancient Aqueous Environment at Meridiani Planum, Mars
Sedimentary rocks at Eagle crater in Meridiani Planum are composed of fine-grained siliciclastic materials derived from weathering of basaltic rocks, sulfate minerals (including magnesium sulfate andExpand
Jarosite and Hematite at Meridiani Planum from Opportunity's Mössbauer Spectrometer
Mössbauer spectra measured by the Opportunity rover revealed four mineralogical components in Meridiani Planum at Eagle crater: jarosite- and hematite-rich outcrop, hematite-rich soil,Expand
Martian fretted terrain: Flow of erosional debris
Abstract Viking orbital photographs of two regions of Martian fretted terrain have revealed a number of landforms which appear to possess distinct flow lineations. These range from valley floors withExpand
The distribution of lobate debris aprons and similar flows on Mars
Planet-wide mapping of lobate debris aprons and other similar flows on Mars shows a strong concentration in two latitudinal bands roughly 25° wide and centered at 40°N and 45°S. This distributionExpand
Distribution of Hydrogen in the Near Surface of Mars: Evidence for Subsurface Ice Deposits
Using the Gamma-Ray Spectrometer on the Mars Odyssey, we have identified two regions near the poles that are enriched in hydrogen. The data indicate the presence of a subsurface layer enriched inExpand
Cassini Imaging Science: Instrument Characteristics And Anticipated Scientific Investigations At Saturn
The Cassini Imaging Science Subsystem (ISS) is the highest-resolution two-dimensional imaging device on the Cassini Orbiter and has been designed for investigations of the bodies and phenomena foundExpand
Alpha Particle X‐Ray Spectrometer (APXS): Results from Gusev crater and calibration report
[1] The chemical composition of rocks and soils on Mars analyzed during the Mars Exploration Rover Spirit Mission was determined by X-ray analyses with the Alpha Particle X-Ray Spectrometer (APXS).Expand
Cassini Imaging of Jupiter's Atmosphere, Satellites, and Rings
The Cassini Imaging Science Subsystem acquired about 26,000 images of the Jupiter system as the spacecraft encountered the giant planet en route to Saturn. We report findings on Jupiter's zonalExpand
