Summary

Description
Українська: Ділянка рівнини Елізій на Марсі. Внизу видно частину долини Лета (Lethe Vallis). Координати центру — 4,493°N, 155,934°E. Розмір зображення — близько 850×850 м, північ угорі. Знімок камери HiRISE на супутнику Mars Reconnaissance Orbiter, контраст збільшено. Висота Сонця — 37°; висота супутника — 282,5 км. Нижче центру видно скупчення кам'яних багатокутників. Такі об'єкти утворюються при регулярному замерзанні й відтаюванні ґрунту, багатого на лід (Balme et al., 2010, New Scientist, 2008).
