Yet fans of NASA’s farthest-flung spacecraft can’t stop talking ... Although we often consider Pluto the end of the solar system, Voyager 1 is more than three times farther than that and ...

The Voyager spacecraft rely on electricity generated from the heat of decaying plutonium, and both are losing an estimated 4 watts of power per year. “The Voyagers have been deep space rock ...

There's more bad news for NASA's Voyager 1 and 2 spacecraft. The twin space probes ... which use radioactively decaying plutonium-238 isotopes as a direct source of power, are losing roughly ...

The decision comes as the Voyager spacecraft face diminishing power supplies due to the gradual decay of their radioactive plutonium. Going where no spacecraft has gone before: NASA shuts down ...

Most RTGs are built using plutonium-238 as their source ... capture the power of RTGs quite like the Voyager missions. NASA launched the twin spacecraft Voyager 1 and Voyager 2 in 1977 to take ...

The Voyager spacecraft rely on electricity generated from the heat of decaying plutonium, and both are losing an estimated 4 watts of power per year. “The Voyagers have been deep space rock ...

Losing 4 watts every year, both Voyagers now run on dwindling plutonium heat—forcing NASA to cut instruments to keep them exploring the void. Launched in 1977, Voyager 1 and 2 have traveled 29 ...
