The mission team at NASA JPL has fixed the communication problem with Voyager 1 and now it's sending back good data to Earth.
The venerable Voyager 1 spacecraft is finally phoning home again. This is much to the relief of mission engineers, scientists, and Voyager fans around the world.
It wasn’t completely surprising that Voyager 1 would have issues, after all. And, this isn’t the first time Voyager 1 has. It’s been traversing space since its launch in 1977. Currently, the spacecraft is rushing away from the Solar System toward interstellar space. The spacecraft systems will eventually fail due to age and lack of power. But, people have always held out hope for them to last as long as possible. That’s because Voyager 1 is probing unexplored regions of space.
They started out by taking the code that packages engineering data and moving it to a safe spot in FDS. Then they sent some commands to the spacecraft for the FDS to do some tasks. That worked because, on April 20th, they heard back from the spacecraft with clear, intelligible data. Now, they just need to do the same thing with other bits of code so that the spacecraft can send back both engineering and science data.
For now, at least, the science and engineering teams can check the spacecraft’s health and its systems. Once they relocate the other bits of code and test them after being moved, they should be able to start receiving science data again. This could take several weeks to accomplish. They’re communicating with a spacecraft that’s 22.5 light-hours away, so having a lengthy diagnostic conversation with Voyager is going to take some time.

Voyager 1: NASA may have just managed to save its historic spacecraftVoyager 1 and 2 launched in 1977 and are NASA’s oldest and most distant robotic space travelers. An issue with Voyager 1’s code that began in November meant the spacecraft was unable to send back data from interstellar space. After some creative engineering to find a solution, Voyager teams got the first usable data from the spacecraft on April 20.
