Potential Mars Landing Site Near Mounds Associated with Crater Rim
ESP_021919_2135  Science Theme: Future Exploration/Landing Sites
This observation shows large mounds that may represent hydrothermal diapirism in a lacustrine (lake) setting, possibly involving fluid movement from great depth. "Diapirism" is a process where a more mobile (and deformable) material is forced up onto overlying material, hence the mounds. An easy point of reference for this process is something most people have seen: a lava lamp.

One of the justifications for this observation is to assess landing/roving hazards and morphology. Additionally, HiRISE has a stereo pair and an anaglyph that helps determine morphology and mineralogy of the mounds and the suitability of a future landing ellipse. This observation also underscores how landing sites are chosen: a safe place to land and explore that is also scientifically compelling.

This caption is based on the original science rationale.
