SUPERPIXEL BASED FACTOR ANALYSIS AND TARGET TRANSFORMATION METHOD FOR MARTIAN MINERALS DETECTION
Superpixel Factor Analysis Target Transformation Minerals detection Mars
2018/5/15
The Factor analysis and target transformation (FATT) is an effective method to test for the presence of particular mineral on Martian surface. It has been used both in thermal infrared (Thermal Emissi...
Crater clusters on Mars:Shedding light on martian ejecta launch conditions
Cratering Mars Meteorites Impact processes
2015/12/25
We have identified two classes of crater clusters on Mars. One class is “small clusters” (crater diameter D ～ tens m, spread over few hundred m), fitting our earlier calculations for the breakup of we...

Tales Martian Rock
2014/12/30
A new analysis of a Martian rock that meteorite hunters plucked from an Antarctic ice field 30 years ago this month reveals a record of the planet's climate billions of years ago, back when water like...
Mineralogical characterization of Martian Jezero crater from MRO CRISM hyperspectral images
Planetary mapping Hyper spectral Minerals Mars
2014/7/23
Martian mineral detection and mapping can provide important information and constraints on Martian aqueous history, which can be used to assess the potential habitability of Mars. The key parameters t...
High-spatial resolution U–Pb dating of phosphate minerals in Martian meteorite Allan Hills 84001
U–Pb dating phosphates NanoSIMS Martian meteorites ALH 84001
2017/4/11
Phosphate minerals, which are ubiquitous in terrestrial and extra-terrestrial rocks, are important carriers of trace elements,
including U and Th, which provide chronological information because of t...

Physicochemical properties concentrated Martian surface waters
2014/4/8
Understanding the processes controlling chemical sedimentation is an important step in deciphering paleoclimatic conditions from the rock records preserved on both Earth and Mars. Clear evidence for s...
A simplified model of the Martian atmosphere-Part 1:a diagnostic analysis
simplified model Martian atmosphere POD-Galerkin analysis
2009/11/11
In this paper we derive a reduced-order approximation to the vertical and horizontal structure of a simplified model of the baroclinically unstable Martian atmosphere. The original model uses the full...

simplified model Martian atmosphere POD-Galerkin analysis
2009/11/11
In Part I of this study Whitehouse et al. (2005) performed a diagnostic analysis of a simplied model of the Martian atmosphere, in which topography was absent and in which heating was modelled as Newt...

Prediction of the structure of the martian upper atmosphere for the Mars Reconnaissance Orbiter (MRO) mission
Mars Reconnaissance Orbiter mapping orbit General Circulation Model predictions
2009/6/1
The Mars Reconnaissance Orbiter (MRO) spacecraft will undergo aerobraking from April through September 2006 in order to achieve the desired mapping orbit. This aerobraking process requires knowledge o...
Martian sub-surface ionising radiation:biosignatures and geology
Martian sub-surface ionising radiation biosignatures geology
2010/1/14
The surface of Mars, unshielded by thick atmosphere or global magnetic field, is exposed to high levels of cosmic radiation. This ionising radiation field is deleterious to the survival of dormant cel...

Martian minerals water
2007/3/22
Mar 17, 2007，Some bright Martian soil containing lots of sulfur and a trace of water intrigues researchers who are studying information provided by NASA's Spirit rover.
Mar 18, 2007，Based on new data, scientists have estimated that the amount of water trapped in frozen layers over Mars' south polar region is enough to cover the entire planet in a liquid layer about 1...
