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.
