  1. FOBOS-GRUNT LANDING SITE SELECTION • T. Basilevsky, T.V. Shingareva • Vernadsky Institute of Geochemistry & Analytical Chemistry, RAS • Kosygin Str., 19, 119991Moscow Russia. • Contact: atbas@geokhi.ru The first Moscow Solar System Symposium (1M-S3) Mars system studies Institute for Space Research, RAN, Moscow October 11-15, 2010

  2. Current landing sites for Fobos-Grunt mission 2 1 Two alternative sites: 1) 5oS, 235oW; 2) 5oN, 230oW

  3. Current landing sites for Fobos-Grunt mission on the map of Peter Thomas

  4. One of new images of Phobos taken by the HRSC camera at the July 22, 2008 flyby with craters seen on previously taken images

  5. Current (red) and suggested (blue) landing sites for Fobos-Grunt Mission on the HRSC image

  6. Results of the photogeologic analysis of the new HRSC images of the suggested landing sites for Fobos-Grunt mission Density of impact craters in the suggested sites is generally lower than on the “average” Phobos. A few gentle sloping grooves are seen. No large rock blocks are seen.

  7. We have determined coordinates of the new sites comparing imaged features on the HRSC and the DLR map 1) 11oN, 226oW; 2) 17oN, 220oW

  8. What can be helpful for Fobos-Grunt project: • New images for photogeologic and geodetic analysis. • New maps based on high-resolution HRSC images for determination of coordinates of the selected sites. • New DTM with improved horizontal and vertical resolution and accuracy for the computer modelling of the landing. • Map of gravity potentials for understanding of potential slopes in the landing sites.

  9. Our next steps : • Photogeologic analysis of new images. • Possible minor changes of the landing site position • Official approval of the new landing sites
