Presentation transcript:

Lobate ejecta from large and fresh crater Long/lat: E, 23.69N E, 23.74N Rational: A crater of diameter ~12 km has exhumed material from deep layers of the clay unit. The ejecta could give access to material from deeper layers that would not be reachable for the rover on any other outcrop. Morphology & mineralogy: Some lobate ejecta are well preserved (dashed line), but HiRISE reveals further lobate ejecta (the dotted line shows a putative limit). These ejecta at HiRISE scale show elongated, lobate features with scattered meter to sub- meter scale bright blocks. The two targets shown by red dots are the two best examples imaged by HiRISE. Most rocks are Fe/Mg-smectite bearing but blocks of different mineralogy are expected. MSL tasks: At large scale, study the extent of the ejecta, the distribution, sizes and morphology of mega-breccia. At small scale, the grain structure, the mineralogy and chemistry of the rocks in the ejecta and blocks. HRSC mosaic with HRSC nadir & color images 1 2
