“…0148-0227/99/1998JE900015509.00 siderations were developed (for the robust lander), and the potential science return at different sites was considered [Golombek et al, 1997a]. Sites (100 'lorn by 200 'lan target ellipses) were considered safe if they were below 0 km elevation (to provide enough atmosphere for parachute descent), were free of hazards in high-resolution (<50 m/pixel) Viking orbiter images (for a reasonably flat stirface for final free fall and bounces), had acceptable reflectivity and rouglmess at radar wavelengths (for proper measurement of closing velocity with the radar altimeter during final descent), and had relatively (compared to Mars average) high thermal inertia (for a relatively dust free and trafficable surface), moderate rock abundance (for scientific analyses), low red to violet ratio, and low albedo (for relatively dust free and/or unweathered rocks).…”

“…The particular utility of understanding the relationship between pressure and topography on Mars is that it provides an estimate of mass of the atmospheric column above a particular location, which is critical in the assessment of potential landing sites. Indeed, elevation relative to the 6.1-mbar surface is one of the key criteria in assessing whether an area of Mars will be safe to land at [Golombek et al, 1997].…”

“…Slope maps have been widely used for scientific research such as landing site selection (Braun and Manning, 2007;Golombek et al, 1997;Golombek et al, 2012) and rover manoeuvre (Lindemann and Voorhees, 2005;Maimone et al, 2007). Thus, the acquisition of an accurate slope map is of great significance.…”

ABSTRACT:The surface slopes of planetary bodies are important factors for exploration missions, such as landing site selection and rover manoeuvre. Generally, high-resolution digital elevation models (DEMs) such as those generated from the HiRISE images on Mars are preferred to generate detailed slopes with a better fidelity of terrain features. Unfortunately, high-resolution datasets normally only cover small area and are not always available. While lower resolution datasets, such as MOLA, provide global coverage of the Martian surface. Slopes generated from the low-resolution DEM will be based on a large baseline and be smoothed from the real situation. In order to carry out slope analysis at large scale on Martian surface based low-resolution data such as MOLA data, while alleviating the smoothness problem of slopes due to its low resolution, this paper presents an amplifying function of slopes derived from lowresolution DEMs based on the relationships between DEM resolutions and slopes. First, slope maps are derived from the HiRISE DEM (meter-level resolution DEM generated from HiRISE images) and a series of down-sampled HiRISE DEMs. The latter are used to simulate low-resolution DEMs. Then the high-resolution slope map is down-sampled to the same resolution with the slope map from the lower-resolution DEMs. Thus, a comparison can be conducted pixel-wise. For each pixel on the slope map derived from the lowerresolution DEM, it can reach the same value with the down-sampled HiRISE slope by multiplying an amplifying factor. Seven sets of HiRISE images with representative terrain types are used for correlation analysis. It shows that the relationship between the amplifying factors and the original MOLA slopes can be described by the exponential function. Verifications using other datasets show that after applying the proposed amplifying function, the updated slope maps give better representations of slopes on Martian surface compared with the original slopes.
