Sdelannyi 7 iyulya s rasstoyaniya v 50 kilometrov etot volnuyushii snimok soderzhit priblizitel'no 1.8 kilometra v poperechnike. Na nem mozhno videt' kraya dvuh bol'shih perekryvayushihsya meteoritnyh kraterov, uhodyashih za gorizont. Massivnye valuny, kotorye mogut byt' oblomkami ot udarov, nahodyatsya po krayam kraterov.
