Ever wondered how long a spacecraft can last? NASA's Voyager 2 is a great example. Launched in 1977, it's still going strong, but things are changing. NASA has turned off one of its science instruments to save power. Why? The plutonium power supply is slowly running out. This isn't the end for Voyager 2, though. It has four other tools still working, studying space beyond our solar system.

Voyager 2 is special. It's the only probe to visit Uranus and Neptune. NASA wants to keep it going as long as possible. But keeping an old spacecraft running isn't easy. The power supply is fading, so NASA had to make a tough choice: turn off one tool now to keep others working longer. By 2030, only one tool might still be on.

Imagine if your phone started turning off apps to save battery. That's what's happening with Voyager 2. It has a magnetometer, particle measurer, cosmic ray detector, and plasma wave detector. These tools help us learn about space. But as the power fades, these tools will eventually shut down too.

Voyager 1 and 2 started together but took different paths. Voyager 2 is more unique because of its visits to ice giants. NASA has been fixing issues with both probes for years. Keeping them running takes a lot of work, but it's worth it. These probes have sent back amazing data about our solar system and beyond.

Sadly, even with these changes, the Voyagers will go silent one day. That day might not be soon, but it's coming. NASA is just trying to make that day as far away as possible. It's like squeezing every last drop of juice from a fruit. You know it won't last forever, but you want to enjoy it for as long as you can.
