5 milyar dolarl\u0131k g\u00f6rev tehlikede<\/b><\/p>\n

Europa Clipper g\u00f6rev ekibi \u00fcyeleri arac\u0131n transist\u00f6rlerinde<\/strong>, yani sonda \u00fczerindeki elektrik ak\u0131\u015f\u0131n\u0131 kontrol eden cihazlarda bir sorun ke\u015ffetti<\/strong>. NASA yetkilileri yapt\u0131klar\u0131 a\u00e7\u0131klamada sorunun, beklenenden daha d\u00fc\u015f\u00fck radyasyon seviyelerinde<\/strong> transist\u00f6rlerin ar\u0131zalanmas\u0131n\u0131n bildirilmesiyle ortaya \u00e7\u0131kt\u0131\u011f\u0131n\u0131 s\u00f6yledi. Bu ciddi bir endi\u015fe kayna\u011f\u0131, \u00e7\u00fcnk\u00fc Clipper, J\u00fcpiter’in ortam\u0131 gibi adeta bir radyasyon cehennemine girecek<\/strong>.<\/p>\n

J\u00fcpiter’in muazzam manyetik alan\u0131 – D\u00fcnya’n\u0131n manyetik alan\u0131ndan 20.000 kat daha g\u00fc\u00e7l\u00fc – y\u00fckl\u00fc par\u00e7ac\u0131klar\u0131 yakalay\u0131p onlar\u0131 \u00e7ok y\u00fcksek enerjilere h\u0131zland\u0131rarak Europa ve di\u011fer i\u00e7 uydular\u0131 bombalayan yo\u011fun radyasyon yarat\u0131yor. Bu da uydulara g\u00f6nderilecek uydular\u0131n a\u015f\u0131r\u0131 radyasyon seviyelerine kar\u015f\u0131 dayan\u0131kl\u0131 olmalar\u0131n\u0131 \u015fart ko\u015fuyor.<\/p>\n

Transist\u00f6rler bozuluyor<\/b><\/p>\n

<\/span> Europa Clipper’\u0131n J\u00fcpiter sistemine 2030 y\u0131l\u0131nda<\/strong> ula\u015fmas\u0131 planlan\u0131yor. Sonda Europa’n\u0131n de\u011fil gaz devinin y\u00f6r\u00fcngesinde d\u00f6necek olsa da dev gezegenin uydusunun etraf\u0131nda epeyce bir zaman ge\u00e7irecek. G\u00f6rev plan\u0131na g\u00f6re Clipper, 3,5 y\u0131ll\u0131k program\u0131 boyunca Europa\u2019ya<\/strong> yakla\u015f\u0131k 50 u\u00e7u\u015f<\/strong> ger\u00e7ekle\u015ftirecek. <\/figure>\n

NASA, halihaz\u0131rda transist\u00f6re testlerine devam ediyor ancak sonu\u00e7lar pek de umut verici de\u011fil. NASA, test verilerine g\u00f6re baz\u0131 transist\u00f6rlerin<\/strong> J\u00fcpiter ve uydusu Europa yak\u0131nlar\u0131ndaki y\u00fcksek radyasyonlu ortamda ar\u0131zalanabilece\u011fini<\/strong> s\u00f6yl\u00fcyor. Ajans, bu ay\u0131n sonuna kadar \u00f6n analizin tamamlanmas\u0131n\u0131 bekliyor. Clipper arac\u0131nda Infineon<\/strong> Technologies<\/strong> taraf\u0131ndan \u00fcretilen metal oksit yar\u0131 iletken alan etkili transist\u00f6rler ya da bilindik adlar\u0131yla MOSFET<\/strong>\u2019ler kullan\u0131l\u0131yor.<\/p>\n

NASA, ar\u0131zalanabilecek transist\u00f6rlerin g\u00f6rev \u00fczerinde y\u0131k\u0131c\u0131 bir etkisi olmayaca\u011f\u0131n\u0131 tespit ederse bir erteleme olmadan mevcut f\u0131rlatma planlar\u0131na devam edebilir. Ancak etkilenen transist\u00f6rlerin etkisi b\u00fcy\u00fck olacaksa g\u00f6revin ertelenmesi de ihtimaller aras\u0131nda.<\/p>\n\n
