Abstract
We have prepared an Atlas of Phobos, which based on new data from Mars Express mission and innovative techniques for recently derived Phobos control point network and shape model (Nadezhdina and Zubarev, 2014; Oberst et al., 2014). The Atlas contains results of Phobos research, based on Mars Express images from the HRSC Camera including its SRC-Channel (Oberst et al., 2008): gravity field working models and studies their characteristics (Uchaev Dm. et al., 2013); geomorphologic properties of craters (Basilevsky et al., 2014); calculations of surface roughness (Karachevtseva et al., 2012); morphometric studies (Kokhanov et al., 2013); statistics of crater size-frequency distributions based on multi-fractal approach (Uchaev Dm. et al., 2012); and surface compositional studies based on HRSC color-channel data (Patsyn et al., 2012). The Atlas includes 42 thematic maps describing various aspects of the surface of the small irregular body with various scale: from global maps (1: 250 000) to several local maps based on images with high resolution (1: 60 000-1: 40 000). The structure of Atlas consists of four chapters and describe some aspects of Phobos research and mapping: 1) History of Phobos mapping in Russia; 2) Control point network, shape model and gravity field of Phobos. 3) GIS-analyses of Phobos’ surface. 4) Geomorphologic studies of Phobos. Different coordinate systems are used to match the map content and Atlas format, for which we choose a page size of A4 (320 mm × 220 mm). The maps are based on the sphere with radius 11.1 km according to IAU recommendations (Archinal et al., 2011). While the Atlas prepared in Russian, feature names is presented in bilingual form (Russian and English). To maintain heritage and continuity with previous mapping of Martian satellite in Russia Atlas includes map of surface based on design of first Russian Phobos map produced for mission Phobos-1 and -2 (1988). The preliminary version of the map was published before the missions started, 30 March, 1988 (now is available at the web-page http://planetologia.elte.hu/ipcd/phobos_map.jpg). During preparation for those missions new cartography projections and map design were developed by Lev Bugaevskiy and Kira Shingareva (Bugaevskiy, 1987; Bugaevskiy et al., 1992). The new Phobos Atlas is held in memory of these Russian cartographers with which efforts was created the first Russian Phobos map. The digital versions of the Phobos maps from the Atlas will be placed into the MIIGAiK Extraterrestrial Laboratory web-page (http://mexlab.miigaik.ru/eng/). Data products which were used for the mapping also will be available at the MExLab Geoportal (http://cartsrv.mexlab.ru/geoportal/) (Karachevtseva et al., 2014). Printed version of a new Phobos Atlas will be presented at the conference.
