NASA engineers found a way to conserve Voyager 2’s dwindling power supply, extending the spacecraft’s mission into at least 2027.

NASA's Voyager 2 is now 49 years old. The probe is more than 13.2 billion miles from Earth, having crossed into interstellar ...

Ten watts may buy Voyager 2 roughly two more years in interstellar space. NASA engineers have reduced the probe’s electrical ...

Somewhere more than 13 billion miles from Earth, a nearly 50-year-old spacecraft is still doing its job. Voyager 2 has been ...

A clever swap has extended the historic Voyager 2’s mission in interstellar space. Engineers are hoping to do the same for Voyager 1.

After 49 years in space, NASA’s Voyagers are running low on power—but an audacious move should extend the tenures of the two spacecraft ...

Find out how a rare planetary alignment made a four-planet grand tour possible, and how nuclear technology keeps these aging ...

Nasa engineers have reconfigured Voyager 2's onboard power systems with a new "Big Bang" upgrade, allowing the nearly 49-year-old spacecraft to continue returning data from interstellar space ...

This artist’s concept shows one of NASA’s Voyager spacecraft entering interstellar space, or the space between stars. This ...

NASA has managed to save so much power on Voyager 2 that the remaining instruments can collect data for at least a year longer.

Voyager 2 runs on radioisotope thermoelectric generators, which turn heat from decaying plutonium into electricity. That heat source weakens over time. The spacecraft generate about 4 fewer watts of ...

After a successful trial on Voyager 2, NASA plans to execute its “big bang” power diversion on humanity’s most distant space probe.
