Mars Reconnaissance Orbiter's High Resolution Imaging Science Experiment (HiRISE)
- A. McEwen, E. Eliason, C. Weitz
- Geology
- 1 May 2007
[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 as…

- C. Porco, P. Helfenstein, S. Squyres
- Geology, PhysicsScience
- 10 March 2006
The shape of Enceladus suggests a possible intense heating epoch in the past by capture into a 1:4 secondary spin/orbit resonance.

- Physics
- 11 March 2010
The Lunar Reconnaissance Orbiter Camera (LROC) Wide Angle Camera (WAC) and Narrow Angle Cameras (NACs) are on the NASA Lunar Reconnaissance Orbiter (LRO). The WAC is a 7-color push-frame camera (100…
Spectral evidence for hydrated salts in recurring slope lineae on Mars
- L. Ojha, M. Wilhelm, M. Chojnacki
- Geology, Physics
- 1 November 2015
Transient streaks that appear seasonally on Martian slopes are consistent with brine flows, but evidence of water or salts has been lacking. Analysis of spectral data reveals hydrated salts…
Cassini Imaging of Jupiter's Atmosphere, Satellites, and Rings
- C. Porco, R. West, A. Vasavada
- Physics, GeologyScience
- 7 March 2003
Findings on Jupiter's zonal winds, convective storms, low-latitude upper troposphere, polar stratosphere, and northern aurora are reported, including previously unseen emissions arising from Io and Europa in eclipse, and a giant volcanic plume over Io's north pole are described.
Ultrahigh resolution topographic mapping of Mars with MRO HiRISE stereo images: Meter‐scale slopes of candidate Phoenix landing sites
- R. Kirk, E. Howington-Kraus, A. McEwen
- Physics, Environmental Science
- 1 March 2008
[1] The objectives of this paper are twofold: first, to report our estimates of the meter-to-decameter-scale topography and slopes of candidate landing sites for the Phoenix mission, based on…
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 found…
THE IMPORTANCE OF SECONDARY CRATERING TO AGE CONSTRAINTS ON PLANETARY SURFACES
- A. McEwen, E. Bierhaus
- Geology, Physics
- 28 April 2006
Small craters (less than one kilometer diameter) can be primary craters produced by impact of interplanetary debris, or they can be secondary craters produced by fallback of high-velocity ejecta…
Terrestrial analogs and thermal models for Martian flood lavas
- L. Keszthelyi, A. McEwen, T. Thordarson
- Geology
- 1 March 1999
The recent flood lavas on Mars appear to have a characteristic “platy-ridged” surface morphology different from that inferred for most terrestrial continental flood basalt flows. The closest analog…
