Voyager-1 now returning science data from all working instruments
Engineers have now resumed full science operations on Voyager-1, presently more 15 billion miles from Earth, after computer issues shut the spacecraft down in November 2023.
The team partially resolved the issue in April when they prompted the spacecraft to begin returning engineering data, which includes information about the health and status of the spacecraft. On May 19, the mission team executed the second step of that repair process and beamed a command to the spacecraft to begin returning science data. Two of the four science instruments returned to their normal operating modes immediately. Two other instruments required some additional work, but now, all four are returning usable science data.
The four instruments study plasma waves, magnetic fields, and particles. Voyager 1 and Voyager 2 are the only spacecraft to directly sample interstellar space, which is the region outside the heliosphere — the protective bubble of magnetic fields and solar wind created by the Sun.
Voyager-2 is 12 billion miles from Earth. Both spacecraft are using what are the longest continously running computers ever built, having been turned on 47 years ago. Both spacecraft however do not have much longer to live, despite the recent fixes. The nuclear power source for both no longer provides enough power to run all their instruments, and will run down completely sometime in 2026, as expected, when operations will finally cease.
The spacecraft however will continue to fly out into interstellar space. In 40,000 years or so Voyager-1 will get within 1.6 light years of the star Gliese 445 in the constellation Camelopardalis, while at the same time Voyager 2 will pass 1.7 light-years from the star Ross 248 in the constellation Andromeda.
Readers!
Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.

We need to do this soon. https://breakthroughinitiatives.org/initiative/3
GeorgeC,
Elon says Starship will reduce the cost of getting stuff into orbit to a few dollars a kg, that SpaceX will soon be building a Starship a day, and that each Starship will fly several times each week.
If those numbers become reality, we’ll soon see telescopes in space larger than any surface based telescopes existing or planned. Then high resolution direct imaging of extrasolar plants will happen at an enormous rate.
