Tsarin sarrafa makamashi na "Big Bang" da aka yi a kan Voyager 2 a watan Yulin 2026 ya tsawaita rayuwar kayan aikin kimiyya guda uku (Magnetometer, Plasma Wave Subsystem, da Cosmic Ray Subsystem) na akalla shekara guda. NASA ta bayar da rahoton nasarar aikin a cikin wani sabuntawa a ranar 4 ga Agusta 2026.    

Tawagar fasaha a dakin gwaje-gwajen Jet Propulsion na NASA ta yi nasarar gudanar da wani tsari na ceton wutar lantarki wanda ya tsawaita rayuwar jirgin sama na Voyager 2 wanda ke ƙarancin wutar lantarki daga janareta.

Tsarin (wanda aka yi wa lakabi da Big Bang saboda musayar na'urori da yawa a lokaci guda) ya ƙunshi kashe na'urorin dumama guda biyu da na'urar rikodin dijital da kunna na'urorin dumama masu ƙarancin wutar lantarki da kuma wata na'urar samar da zafi don kiyaye jirgin sama mai ɗumi don yin aiki a sararin samaniya tsakanin taurari a kusan 2.7 K. Wannan ya haifar da adana wutar lantarki kusan watts 10 (ba tare da wani mummunan tasiri ga tsarin mahimmanci ba) wanda ya isa ya ba da damar sauran kayan aikin kimiyya guda uku (Magnetometer, Plasma Wave Subsystem, da Cosmic Ray Subsystem) su ci gaba da aiki na akalla shekara ɗaya. Ba tare da tsarin ceton wutar lantarki ba, da waɗannan kayan aikin dole ne a kashe su kafin ƙarshen wannan shekarar. 

Jiragen sama jannatin Voyager suna amfani da na'urorin samar da wutar lantarki na radioisotope thermoelectric (RTG) waɗanda ke canza zafi daga ruɓewar plutonium zuwa wutar lantarki. Jiragen sun rasa watts 4 na wutar lantarki a kowace shekara saboda ƙarancin wutar lantarki na plutonium tun lokacin da aka ƙaddamar da su a 1977. Jiragen sama jannatin suna aiki a kan ƙarancin wutar lantarki wanda ke buƙatar rufe kayan aiki da tsarin da ba su da mahimmanci don adana makamashi. 

Voyager 2 a halin yanzu tana da nisan kilomita biliyan 21.37 daga Duniya tana tafiya a sararin samaniya tsakanin taurari. Voyager 1 tana da nisan kilomita biliyan 25.57 daga Duniya. Su ne kawai jirgin sama mai saukar ungulu da ya taɓa ratsa sararin samaniyar rana zuwa sararin samaniya tsakanin taurari.
