Vyzhivshii: NEAR-Shoemaker na asteroide Eros
Avtory i prava: NEAR Project, NASA
Poyasnenie: Net, eto ne televizionnyi serial. Komicheskii apparat NEAR-Shoemaker deistvitel'no vyzhil v proshlom mesyace posle besprecedentnoi posadki na asteroide. Vrezka na risunke illyustriruet predpolagaemoe polozhenie zonda na poverhnosti, kotoryi pokoitsya teper', opirayas' na koncy panelei solnechnyh batarei, progibayushiesya pod deistviem slabogo prityazheniya Erosa. K schast'yu, solnechnye batarei kosmicheskogo apparata okazalis' posle posadki osvesheny Solncem, chto pozvolilo snabzhat' energiei gamma-spektrometr NEAR. Rabotaya na poverhnosti, etot pribor mozhet, izmeryaya signatury gamma-izlucheniya atomnyh yader, opredelit' sostav grunta Erosa na glubine do 10 santimetrov s tochnost'yu, na kotoruyu prezhde nel'zya bylo rasschityvat'. Poluchennye s poverhnosti Erosa dannye predstavleny na grafike, gde otchetlivo vidny piki, sootvetstvuyushie zhelezu, kislorodu, kremniyu i kaliyu, soderzhashimsya v regolite asteroida. Nenadolgo vklyuchennyi bortovoi magnitometr podtverdil, chto magnitnogo polya na poverhnosti Erosa net. Teper' apparat NEAR-Shoemaker vyklyuchen i na milliardy let ostanetsya lezhat' nepodaleku ot ogromnoi sedloviny Himeros. Odnako paneli solnechnyh batarei apparata budut periodicheski povorachivat'sya k Solncu vsledstvie dvizheniya asteroida po svoei orbite... I v takie momenty, spyashii apparat, vozmozhno, eshe prosnetsya.
