Voyager 1 and 2, meanwhile, are always on the verge of a more lasting breakdown. Even if all of their systems perform optimally going forward, the spacecrafts are still not expected to survive ...

As humanity’s first emissaries into the vast reaches of interstellar space, the Voyager 1, Voyager 2, and Pioneer probes have ...

NASA’s Voyager 1 spacecraft is depicted in this artist’s concept traveling through interstellar space, or the space between stars, which it entered in 2012. (NASA/JPL-Caltech) ...

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.

The Voyager 1 probe, the first human-made object to reach the space between stars, has suffered a serious problem that NASA experts are struggling to understand and repair.

Voyager 1 is so far away that it takes 22.5 hours for commands sent from Earth to reach the spacecraft. Additionally, the team must wait 45 hours to receive a response.

Voyager 1 and its twin, Voyager 2, have outlasted many of those who designed and built them. So to try to fix Voyager 1's current woes, the dozen or so people on Dodd's team have had to pore over ...

NASA figured it out what was going on with Voyager 1 and why it was sending weird messages to Earth. Now, it will operate smoothly for years to come.

NASA has explored the space beyond Earth and our solar system with spacecraft like Voyagers 1 and 2, and how we’ve discovered ...

NASA scientists are able to fire up a set of thrusters on Voyager 1 for the first time since 1980, allowing the spacecraft to orient itself in interstellar space, 13 billion miles from Earth.

Voyager 1 is now so far from Earth that commands take more than 17 hours to reach it. But it will be a little while before the spacecraft will encounter any more planets.
