DALLAS (AP) — NASA’s Voyager 1 spacecraft is sending science data again.

The Jet Propulsion Laboratory says the spacecraft’s four instruments are back in business after a computer problem in November.

The team first received meaningful information from Voyager 1 in April and recently commanded it to start sending science data.

Launched in 1977, Voyager 1 is the most distant spacecraft from Earth.

It’s exploring interstellar space, or the space between star systems.

Its twin, Voyager 2, is working fine.
