NASA announced this week that they have turned off one of Voyager 1's science instruments. The spacecraft has been exploring space since 1977. It is now the farthest human-made object from Earth. Scientists say the spacecraft still sends information back to us. Voyager 1 has traveled for nearly 50 years. It studies the space around it and sends data to Earth. Scientists are excited about the information they receive.
The spacecraft has limited power. Scientists need to manage the power carefully. This is why NASA decided to switch off one instrument. The decision will help keep other systems running. Scientists made this choice to extend the spacecraft's life. Voyager 1 is very old, but it still works. People are amazed that it keeps sending data. Scientists want to keep the spacecraft alive as long as possible.
