On a single day last November, two spacecraft millions of kilometers apart turned their ultraviolet eyes toward the same ...

The LECP has been operating almost without interruption since the Voyager 1 and 2 probes launched in 1977. Meanwhile, the power output of Voyager 1's RTGs has been declining by about 4 watts per year, ...

The farthest spacecraft from Earth has shut down another instrument in the hopes of buying time for an upgrade that could boost the aging probe’s impressive lifespan.

NASA's twin Voyager spacecraft are still flying in interstellar space. But their power is dwindling, and it's unclear how much longer they can last.

The Southwest Research Institute-led Ultraviolet Spectrograph (UVS) instruments aboard ESA's Jupiter Icy Moons Explorer (Juice) spacecraft and NASA's Europa Clipper made unique observations of ...

The Southwest Research Institute-led Ultraviolet Spectrograph (UVS) aboard ESA’s Jupiter Icy Moons Explorer (Juice) spacecraft observed the interstellar comet 3I/ATLAS, revealing higher levels of ...

In 1977, NASA launched an ambitious mission: Two spacecraft called Voyager 1 and Voyager 2 blasted off to investigate Jupiter and Saturn. They’re still gathering data today—now, in interstellar ...

Nasa is rushing to find a solution to prevent its first interstellar spacecraft from running out of power. Voyager 1, which launched in 1977, suffered a drop in power levels that forced mission ...

NASA has confirmed that after a pause in communications with Voyager 1 in late October, the spacecraft has regained its voice and resumed regular operations. Voyager unexpectedly turned off its ...

Interstellar space is unforgivingly vast, but the emptiness has some advantages. The lack of atmosphere means there is no aerodynamic drag. So when the ship reaches its cruise spe ...

In November 2025, two spacecraft on opposite sides of an interstellar comet did something no observatory on or near Earth ...
