Global Mineralogical and Aqueous Mars History Derived from OMEGA/Mars Express Data
Global mineralogical mapping of Mars by the Observatoire pour la Mineralogie, l'Eau, les Glaces et l'Activité (OMEGA) instrument on the European Space Agency's Mars Express spacecraft provides new
Mars Orbiter Laser Altimeter: Experiment summary after the first year of global mapping of Mars
The Mars Orbiter Laser Altimeter (MOLA), an instrument on the Mars Global Surveyor spacecraft, has measured the topography, surface roughness, and 1.064-μm reflectivity of Mars and the heights of
The global topography of Mars and implications for surface evolution.
Elevations measured by the Mars Orbiter Laser Altimeter have yielded a high-accuracy global map of the topography of Mars. Dominant features include the low northern hemisphere, the Tharsis province,
Surface of Young Jupiter Family Comet 81P/Wild 2: View from the Stardust Spacecraft
Images taken by the Stardust mission during its flyby of 81P/Wild 2 show the comet to be a 5-kilometer oblate body covered with remarkable topographic features, including unusual circular features
Observations of the north polar region of Mars from the Mars orbiter laser altimeter.
Elevations from the Mars Orbiter Laser Altimeter (MOLA) have been used to construct a precise topographic map of the martian north polar region and correlation of topography with images suggests that the cap was more spatially extensive in the past.
Comet 81P/Wild 2 Under a Microscope
The Stardust spacecraft collected thousands of particles from comet 81P/Wild 2 and returned them to Earth for laboratory study. The preliminary examination of these samples shows that the nonvolatile
Grooves on Phobos: Their distribution, morphology and possible origin
A remarkable characteristic of the surface of Phobos is that it is densely covered by grooves—long linear depressions formed in a regolith. Typically, grooves are 100–200 m wide, 10–20 m deep, and
Astrometric observations of Phobos and Deimos with the SRC on Mars Express
Observations of Phobos and Deimos, carried out by the SRC (Super Resolution Channel) on the Mars Express spacecraft between May 2004-April 2005, were used to determine the center-of-figure positions
