Ancak arac\u0131n enerji kaynaklar\u0131n\u0131n t\u00fckenmeye ba\u015flamas\u0131 nedeniyle, bilim insanlar\u0131 enerji tasarrufu sa\u011flamak i\u00e7in Voyager 2\u2019nin plazma bilimi<\/strong> deneyini kapatma karar\u0131 ald\u0131. <\/figure>\n

Voyager 2, 20 A\u011fustos 1977’de f\u0131rlat\u0131ld\u0131 ve 5 Kas\u0131m 2018’de G\u00fcne\u015f Sistemi’nden \u00e7\u0131karak y\u0131ld\u0131zlararas\u0131 uzaya girdi. \u015eu anda D\u00fcnya’dan yakla\u015f\u0131k 20,6 milyar kilometre uzakta<\/strong> bulunuyor ve d\u00f6rt bilimsel arac\u0131yla heliosferin (G\u00fcne\u015f’in etkisinin sona erdi\u011fi b\u00f6lge) \u00f6tesindeki uzay\u0131 inceliyor. Ancak enerji kaynaklar\u0131 t\u00fckenmeye ba\u015flad\u0131k\u00e7a, NASA’n\u0131n daha fazla cihaz\u0131 kapatmas\u0131 gerekecek. Yetkililer, Voyager 2’nin 2030’lara kadar bir bilimsel arac\u0131 \u00e7al\u0131\u015f\u0131r durumda tutabilece\u011fini <\/strong>d\u00fc\u015f\u00fcn\u00fcyor.<\/p>\n

Voyager 2 ne kadar uzakta?<\/b><\/p>\n

<\/span> Bu arada ba\u011flam a\u00e7\u0131s\u0131ndan Voyager 2\u2019nin ne kadar uzakta oldu\u011fu hakk\u0131nda da biraz detay verelim. Voyager 2\u2019nin D\u00fcnya\u2019ya uzakl\u0131\u011f\u0131 belirtti\u011fimiz gibi 20,6 milyar kilometre<\/strong>. Bu ayn\u0131 zamanda yakla\u015f\u0131k 137 AU<\/strong> yani Astronomik Birim\u2019e denk geliyor. Bilmeyenler i\u00e7in AU, bir uzunluk birimi konumunda ve D\u00fcnya ile G\u00fcne\u015f aras\u0131ndaki mesafeyi temsil ediyor. O da 149.6 milyon kilometre civar\u0131nda. <\/figure>\n
<\/span> Buna ek olarak Voyager 2 ile olan ileti\u015fimimiz \u0131\u015f\u0131k h\u0131z\u0131nda<\/strong> ger\u00e7ekle\u015fiyor. Bu ba\u011flamda Voyager 2, \u0131\u015f\u0131k h\u0131z\u0131nda bizden tam 19 saat 5 dakika uzakta<\/strong>. Yani, Voyager ile ileti\u015fim kurmak i\u00e7in 38 saate (sinyali g\u00f6ndermemiz ve almam\u0131z) ihtiya\u00e7 duyuyoruz. Yani plazma bilimi enstr\u00fcman\u0131n\u0131 kapatma i\u015fleminin ba\u015far\u0131l\u0131 oldu\u011funu 38 saat sonra \u00f6\u011frenebildik. Bu, inan\u0131lmaz bir uzakl\u0131k. \u00d6rne\u011fin G\u00fcne\u015f\u2019in \u0131\u015f\u0131\u011f\u0131 bize yakla\u015f\u0131k 8 dakikada ula\u015f\u0131yor. <\/figure>\n

Voyager 2\u2019nin kapat\u0131lan cihaz\u0131 ne yap\u0131yordu?<\/b><\/p>\n

<\/span> Son olarak kapat\u0131lan plazma bilimi cihaz\u0131, uzaydaki plazma miktar\u0131n\u0131 ve y\u00f6n\u00fcn\u00fc \u00f6l\u00e7en d\u00f6rt k\u00fc\u00e7\u00fck kab\u0131 i\u00e7eriyordu. Bu cihaz, Voyager 2’nin 2018 y\u0131l\u0131nda heliosferin d\u0131\u015f\u0131na \u00e7\u0131kt\u0131\u011f\u0131n\u0131 tespit eden \u00f6nemli bir ara\u00e7t\u0131. Ancak arac\u0131n G\u00fcne\u015f\u2019e bakan \u00fc\u00e7 kab\u0131, G\u00fcne\u015f r\u00fczgar\u0131n\u0131n etkisinin sona ermesiyle birlikte veri toplamay\u0131 durdurdu ve cihaz\u0131n etkinli\u011fi s\u0131n\u0131rl\u0131 hale geldi. <\/figure>\n

NASA’n\u0131n Jet \u0130tki Laboratuvar\u0131’ndan yap\u0131lan a\u00e7\u0131klamada, 47 ya\u015f\u0131ndaki uzay arac\u0131nda yap\u0131lan her de\u011fi\u015fikli\u011fin dikkatle izlendi\u011fi ve plazma cihaz\u0131n\u0131n kapat\u0131lmas\u0131n\u0131n sorunsuz ger\u00e7ekle\u015fti\u011fi belirtildi. Voyager 2, mevcut cihazlar\u0131yla normal bir \u015fekilde \u00e7al\u0131\u015fmaya devam ediyor.<\/p>\n

Voyager 2’nin y\u00f6nelimi nedeniyle plazma cihaz\u0131, sadece \u00fc\u00e7 ayda bir veri toplayabiliyordu. Bu durum, NASA’n\u0131n di\u011fer cihazlar yerine plazma cihaz\u0131n\u0131 kapatma karar\u0131nda etkili oldu. Uzay arac\u0131n\u0131n enerjisi, plutonyumun do\u011fal radyoaktif bozunumundan sa\u011flan\u0131yor ve her y\u0131l yakla\u015f\u0131k 4 watt g\u00fc\u00e7 kaybediyor.<\/p>\n

Daha \u00f6nce 1980’lerde devre d\u0131\u015f\u0131 b\u0131rak\u0131lan baz\u0131 cihazlar sayesinde Voyager 2’nin g\u00f6rev s\u00fcresi uzat\u0131lm\u0131\u015ft\u0131. \u015eimdiye kadar uzay arac\u0131n\u0131n ba\u015flang\u0131\u00e7taki 10 aletinden 6\u2019s\u0131 devre d\u0131\u015f\u0131<\/strong> b\u0131rak\u0131ld\u0131. Halihaz\u0131rda sadece Kozmik \u0131\u015f\u0131n alt sistemi (Cosmic Ray Subsystem, CRS), D\u00fc\u015f\u00fck enerji y\u00fckl\u00fc par\u00e7ac\u0131klar (LECP), Manyetometre (MAG) ve Plazma dalgas\u0131 alt sistemi (PWS) faal durumda.<\/p>\n\n
