ʻO ke kaʻina hana hoʻokele ikehu "Big Bang" i hana ʻia ma Voyager 2 i Iulai 2026 ua hoʻolōʻihi i ke ola hana o ʻekolu mau mea hana ʻepekema (Magnetometer, Plasma Wave Subsystem, a me Cosmic Ray Subsystem) no hoʻokahi makahiki keu. Ua hōʻike ʻia ka holomua o ke kaʻina hana e NASA ma kahi hōʻano hou ma ka lā 4 ʻAukake 2026.    

Ua hoʻokō pono ke kime loea ma ka Jet Propulsion Laboratory o NASA i kahi kaʻina hana mālama mana i hoʻolōʻihi i ke ola hana o ka mokulele Voyager 2 e pau ana ka mana mai kāna mīkini hana.

ʻO ke kaʻina hana (i kapa ʻia ʻo Big Bang ma muli o ka hoʻololi ʻana o nā mea hana he nui i ka manawa like) e pili ana i ka hoʻopau ʻana i ʻelua mau mea hoʻomehana i hoʻolaʻa ʻia a me kahi mea hoʻopaʻa leo kikohoʻe a me ka hoʻohuli ʻana i nā mea hoʻomehana ʻē aʻe me ka mana haʻahaʻa a me kahi mea hana wela ʻē aʻe e hoʻomau i ka mahana o ka mokulele e hana ai ma ka lewa interstellar ma kahi o 2.7 K. ʻO ka hopena o kēia, ua mālama ʻia ka mana o kahi kokoke i 10 watts (me ka ʻole o ka hopena maikaʻi ʻole i nā ʻōnaehana koʻikoʻi) i lawa ia e ʻae i nā mea hana ʻepekema ʻekolu i koe (Magnetometer, Plasma Wave Subsystem, a me Cosmic Ray Subsystem) e hoʻomau i ka holo no hoʻokahi makahiki keu. Me ka ʻole o ke kaʻina hana mālama mana, pono e hoʻopau ʻia kēia mau mea hana i ka hopena o kēia makahiki. 

Hoʻohana ʻia nā mokulele Voyager e nā mea hana thermoelectric radioisotope (RTG) e hoʻololi i ka wela mai ka plutonium palaho i uila. Ua nalowale nā ​​​​mea hana i 4 watts o ka mana i kēlā me kēia makahiki ma muli o ka emi ʻana o ka lako plutonium mai ko lākou hoʻomaka ʻana i ka makahiki 1977. Ke hana nei nā mokulele i kēia manawa ma nā palena mana lahilahi loa e koi ana i ka pani ʻana i nā mea hana a me nā ʻōnaehana pono ʻole e mālama i ka ikehu. 

Aia ʻo Voyager 2 i kēia manawa ma kahi o 21.37 biliona km mai ka Honua e hele ana ma ka lewa interstellar. ʻOi aku ka mamao o Voyager 1 ma kahi o 25.57 biliona km mai ka Honua. ʻO lākou wale nō ka moku mokulele i hele ma waena o ka heliosphere o ka Lā a hiki i ka lewa interstellar.
