Teni na yuzhnom polyuse Luny
Avtory i prava: NASA / Kosmicheskii centr Goddard / Gosudarstvennyi universitet Arizony / Lunar Rekonnessans Orbiter
Perevod: Vol'nova A.A.
Poyasnenie: Chto eto? Eto karta zasvetki v zavisimosti ot vremeni. Chtoby sdelat' ee, sputnik Lunar Rekonnesans Orbiter (Lunar Reconnaissance Orbiter) sdelal svoei shirokougol'noi kameroi 1700 snimkov v techenie 6 lunnyh dnei (6 zemnyh mesyacev). Eti snimki pokryvali odin i tot zhe uchastok Lunnoi poverhnosti vokrug yuzhnogo polyusa. Dalee vse kartinki pereveli v dvoichnyi vid (temnym uchastkam prisvoili znachenie 0, a svetlym — 1) i slozhili. Poluchilas' karta, pokazyvayushaya procentnoe sootnoshenie osveshennosti Solncem toi ili inoi oblasti. Bez somneniya, dno 19-kilometrovogo kratera Sheklton postoyanno nahoditsya v teni. Krater viden pochti v centre kartinki. Sam lunnyi yuzhnyi polyus nahoditsya v levoi chasti obodka kratera. Tak kak os' vrasheniya Luny ostaetsya vse vremya prakticheski perpendikulyarnoi ploskosti ekliptiki, nizhnie chasti kraterov vozle yuzhnogo i severnogo polyusov Luny postoyanno nahodyatsya v teni, a vershiny gornyh hrebtov postoyanno osvesheny Solncem. Eto polezno dlya budushih Lunnyh baz: v postoyanno temnye kotlovany kraterov mogut sluzhit' estestvennymi rezervuarami vodyanogo l'da, a na osveshennyh gornyh vershinah mozhno raspolozhit' solnechnye batarei.
