ဗွိုင်ယေဂျာတို့၏ပင်မတာဝန်သည် ''ဗွိုင်ယေဂျာ၂''အား ၁၉၈၉တွင် နက်ပကျွန်းဂြိုဟ်အနီးမှဖြတ်သန်းပျံသန်းပြီးနောက်ပြီးဆုံးသွားခဲ့ပြီဖြစ်သည်။ The Voyager Interstellar Mission (VIM) is a mission extension, which began when the two spacecraft had already been in flight for over 12 years.<ref>{{cite web |url=http://voyager.jpl.nasa.gov/mission/interstellar.html |title=Interstellar Mission |publisher=NASA}}</ref> The Heliophysics Division of the NASA Science Mission Directorate conducted a Heliophysics Senior Review in 2008. The panel found that the VIM "is a mission that is absolutely imperative to continue" and that VIM "funding near the optimal level and increased DSN ([[Deep Space Network]]) support is warranted."<ref>{{cite web |url=http://www.igpp.ucla.edu/public/THEMIS/SCI/Pubs/Proposals%20and%20Reports/Senior%20Review%202008%20Report%20Final.pdf |title=Senior Review 2008 of the Mission Operations and Data Analysis Program for the Heliophysics Operating Missions |page=7 |publisher=NASA|format=PDF|archiveurl=http://web.archive.org/20080626213548/www.igpp.ucla.edu/public/THEMIS/SCI/Pubs/Proposals%20and%20Reports/Senior%20Review%202008%20Report%20Final.pdf|archivedate=2008-06-26}}</ref>
As of the present date, the ''Voyager 2'' and ''Voyager 1'' scan platforms, including all of the platform instruments, have been powered down. The ultraviolet spectrometer (UVS)<ref>{{cite web | title=Ultraviolet Spectrometer | work=Voyager: The Interstellar Mission | publisher = NASA JPL | url=http://voyager.jpl.nasa.gov/spacecraft/instruments_uvs.html | accessdate=2006-06-11}}</ref> on ''Voyager 1'' was active until 2003, when it too was deactivated. Gyro operations will end in 2015 for ''Voyager 2'' and 2016 for ''Voyager 1''. Gyro operations are used to rotate the probe 360 degrees six times per year to measure the [[magnetic field]] of the spacecraft, which is then subtracted from the [[magnetometer]] science data.
The two ''Voyager'' spacecraft continue to operate, with some loss in subsystem redundancy, but retain the capability of returning scientific data from a full complement of Voyager Interstellar Mission (VIM) science instruments.
Both spacecraft also have adequate electrical power and attitude control propellant to continue operating until around 2025, after which there may not be available electrical power to support science instrument operation. At that time, science data return and spacecraft operations will cease.<ref>{{cite web|url=http://voyager.jpl.nasa.gov/spacecraft/spacecraftlife.html| title=Voyager - Spacecraft Lifetime NASA website|accessdate=2011-09-13}}</ref>
