After many months of extremely long-distance repairs, NASA’s Voyager 1 space probe is fully operational once again. “The spacecraft has resumed gathering information about interstellar space ...

Given Voyager 1's immense distance from Earth, it takes a radio signal about 22.5 hours to reach the probe, and another 22.5 hours for a response signal from the spacecraft to reach Earth.

Still, Voyager 1's ground team identified the FDS as the likely source of the problem. The Flight Data Subsystem was an innovation in computing when it was developed five decades ago.

Voyager 1 took the last picture, affectionately known as the solar system family portrait, on Feb. 14, 1990. While the spacecraft are still functioning today, most of their other instruments have ...

In 2012, Voyager 1 became the first spacecraft to reach interstellar space. Last year, Voyager 2 joined its companion in the interstellar medium, reaching the boundary set 119 times the Earth ...

This is an artist's impression of Voyager 1's position on the sky when observed by the Very Long Baseline Array (VLBA) on Feb. 21, 2013, at which point -- according to NASA's Jet Propulsion ...
