The Syrtis Major volcanic province, Mars: Synthesis from Mars Global Surveyor data
[1] We investigated the geology, stratigraphy, morphology, and topography of Syrtis Major, one of the large Hesperian-aged volcanic provinces on Mars. New data from the Mars Global Surveyor (MGS) and Odyssey spacecraft allowed us to study Syrtis Major in unprecedented detail. On the basis of Mars Orbiter Laser Altimeter (MOLA) data we estimated the thickness of Syrtis Major lavas to be on the o...
متن کاملThe gravity field of Mars: results from Mars Global Surveyor.
Observations of the gravity field of Mars reveal a planet that has responded differently in its northern and southern hemispheres to major impacts and volcanic processes. The rough, elevated southern hemisphere has a relatively featureless gravitational signature indicating a state of near-isostatic compensation, whereas the smooth, low northern plains display a wider range of gravitational ano...
متن کاملAn Orthoimage Map Using Data Obtained from the Mars Orbiter Camera of Mars Global Surveyor
A basic requirement for the planning of future Mars missions are precise and high resolution maps, especially, of the landing site area. We present a new digital orthoimage map of Mars using data obtained from the Mars Orbiter Camera (MOC) of the Mars Global Surveyor (MGS). The new map covers the Mars surface from 180° E (180° W) to 360° E (0° W) and from 60° South to 60° North with a resolutio...
متن کاملSilica deposits in the Nili Patera caldera on the Syrtis Major volcanic complex on Mars
The martian surface features abundant volcanoes and evidence for past liquid water. Extant or relict martian volcanic hydrothermal systems have therefore been sought in the pursuit of evidence for habitable environments1. The Mars Exploration Rover, Spirit, detected deposits highly enriched in silica with accessory minerals, suggesting formation by hydrothermal leaching of basaltic rocks by low...
متن کاملOverview of the Mars Global Surveyor mission
The Mars Global Surveyor spacecraft was placed into Mars orbit on September 11, 1997, and by March 9, 1999, had slowly circularized through aerobraking to a Sunsynchronous, near-polar orbit with an average altitude of 378 km. The science payload includes the Mars Orbiter Camera, Mars Orbiter Laser Altimeter, Thermal Emission Spectrometer, Ultrastable Oscillator (for Radio Science xperiments), a...
