An illustration shows the position of NASA’s Voyager 1 and Voyager 2 probes. On Dec. 10, 2018, NASA announced that Voyager 2 had joined Voyager 1 in interstellar space.

Voyager 1 and 2 were both launched in reverse order 16 days apart in 1977. Their goal was to explore the outer planets of our solar system, while Voyager 2 remains the only probe to get up close ...

In the latest shutdown, the cosmic ray subsystem experiment on Voyager 1 and Voyager 2’s low-energy charged particle ...

And half of the 50 years, NASA Voyager 1 has spent billions of miles traveling into interstellar space. In October, it went ...

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

They were also not the first missions to carry a message intended for extraterrestrial beings should they reach interstellar ...

Nearly 50 years after they were first launched, Voyager 1 and 2 are still traveling around interstellar space — though they've faced some setbacks over the years. Now, NASA has announced that ...

V oyager 1 – and its sibling, Voyager 2 – were always meant to be a testament to humanity’s ingenuity. When they left Earth in the summer of 1977, they did so carrying a record that was ...

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 ...

Although this provided Voyager 1 and 2 with about 470 W at 30 volts when they launched in 1977, the plutonium’s 87.74-year half-life means they have annually lost roughly 0.79-percent their power.

NASA and Voyager 1 resumed communications and operations after a fault protection system switched the interstellar spacecraft's mode of communication to one using less power.

On February 25, NASA’s Jet Propulsion Laboratory (JPL) turned off Voyager 1's cosmic ray subsystem experiment and on March 25, it will shut down Voyager 2's low-energy charged particle instrument.
