Derivation of planetary topography using multi-image shape-from-shading
Kirk, Randolph L.; Lohse, Volker; Heipke, Christian
In many cases, the derivation of high-resolution digital terrain models (DTMs) from planetary surfaces using conventional digital image matching is a problem. The matching methods need at least one stereo pair of images with sufficient texture. However, many space missions provide only a few stereo images and planetary surfaces often possess insuf…
OMEGA/Mars Express: Visual channel performances and data reduction techniques
Gondet, B.; Langevin, Y.; Poulet, F. +4 more
In this paper we discuss the on-ground and in-flight performances of the visual channel of the OMEGA instrument on board the European mission Mars Express. OMEGA is a mapping spectrometer designed for mineralogical and atmospheric investigation of Mars. This work aims to be a guide to future users for the analysis of the OMEGA data. We give a deta…
Evidence for an Hesperian-aged South Circum-Polar Lake Margin Environment on Mars
Head, James W.; Dickson, James
A broad pitted plain and an elongated low rise occur near the south pole of Mars between a region of major cavi (Cavi Angusti) and a regionally smooth and broad valley (Argentea Planum). Viking, Mars Global Surveyor (MGS), and Odyssey data reveal a densely pitted plain covering ∼6750 km 2, and containing >300 irregularly shaped, stee…
The planetary fourier spectrometer (PFS) onboard the European Venus Express mission
Baines, K. H.; Grigoriev, A.; Bellucci, G. +47 more
The planetary fourier spectrometer (PFS) for the Venus Express mission is an infrared spectrometer optimized for atmospheric studies. This instrument has a short wavelength (SW) channel that covers the spectral range from 1700 to 11400 cm -1 (0.9-5.5 µm) and a long wavelength (LW) channel that covers 250-1700 cm -1 (5.5…
Top layers charaterization of the Martian surface: Permittivity estimation based on geomorphology analysis
Kofman, W.; Herique, A.; Nouvel, J. -F. +1 more
Mars Express spacecraft inserted successfully Martian orbit at the end of 2003. On board this probe, a radar instrument called MARSIS (for Mars Advanced Radar for Surface and Ionosphere Sounding) is looking for water inside the first kilometers of Martian crust. To support MARSIS planning and data inversion, Laboratoire de Planétologie de Grenoble…
Digging deep for ice in Isidis Planitia—New constraints on subsurface volatile concentrations from thermal modeling
Helbert, J.; Benkhoff, J.
The Isidis Planitia region on Mars usually is regarded as a comparably attractive site for landing missions based on engineering constraints such as elevation and smooth regional topography. The Mars Express landed element Beagle 2 was deployed to this area, and the southern margin of the basin was selected as one of the backup landing sites for t…
